Non-Compete Agreement for Selling a Business: How to Make It Enforceable

When a buyer acquires a mid-market business, a significant portion of the purchase price is not paid for machinery, inventory, or contracts. It is paid for the seller's position in the market, the customer relationships built over years, the supplier networks, the regulatory standing, the reputation that makes the business worth acquiring rather than building from scratch. That position is what economists call goodwill, and it is what a non-compete agreement is designed to protect.

‍

The protection logic is simple: if the seller can begin reconstructing that competitive position the day after closing, the buyer has paid a goodwill premium for something that will not transfer. The non-compete is the mechanism that creates the window, typically two to three years, during which the acquired relationships can migrate to the new owner without the seller actively working to recapture them.

‍

In practice, non-compete clauses fail in two distinct ways. The first is a clause drafted too narrowly to capture what the seller actually does after closing, covering formal employment or equity ownership while leaving informal advisory conduct, financing, and supplier introductions entirely unrestricted. The second is a clause drafted too broadly to survive judicial scrutiny, voided on grounds of geographic overbreadth or an activity definition so vague the seller cannot identify what is restricted without the buyer's interpretation. Both failures produce the same outcome: the acquisition price paid for goodwill is unprotected.

‍

A 2025 English High Court decision illustrates the first failure mode with unusual clarity, and maps directly onto the structural risks that define founder-led acquisitions in CEE mid-market transactions.

‍

The seller signed at closing in December. By October the following year, his former employees were operating a competing business in the same market, supplied by the same vendors, serving many of the same customers, with his financial support, his supplier introductions, and his description of their venture as a “sister” of the business he had just sold.

‍

This is not a hypothetical. It is the factual background of Spill Bidco Ltd v Wishart [2025] EWHC 2513 (Comm), an English High Court decision that every acquirer structuring a mid-market deal should have read. While based on English law, the case is illustrative of broader interpretive issues relevant in CEE jurisdictions. The founder held no formal position in either competing business, had no equity in either, and made no employment arrangement. He believed this kept him outside the scope of his non-compete covenant. The court found otherwise.

‍

This article covers the full structure of an enforceable non-compete agreement in a business sale context: the legal distinction from employment restrictions, the four structural requirements courts apply across CEE jurisdictions, the drafting decisions that determine whether a clause holds under pressure, and the jurisdiction-specific requirements in Hungary and Romania. It also addresses the question that most non-compete guidance ignores: whether a correctly drafted restriction is, by itself, sufficient to protect the goodwill the buyer paid for, and why the answer is consistently no.

‍

Why Business Sale Non-Competes Are a Distinct Legal Category

When an employee signs a post-termination restriction, courts balance the employer’s interest in protecting trade secrets against the employee’s constitutional right to work. This creates a high burden: post-employment non-competes are narrowly constructed, temporally limited, and frequently subject to mandatory compensation requirements.

‍

In Romania, employment non-competes under the Labour Code require monthly compensation payments of at least 50% of the employee’s average gross salary for the final six months of employment, while terms are capped at 24 months post-termination. In Hungary, the Labour Code requires compensation equivalent to at least one-third of the employee’s base salary owed during the restricted period, the restriction being also capped at 24 months. These figures define the employment-context floor. 

‍

The seller of a business is not an employee, the above rules do not apply to non-compete clauses tied to the sale of a business The seller received market value, including a premium for goodwill, customer relationships, and operational know-how, in exchange for both the business and the undertaking not to reconstruct it immediately elsewhere. Thus, courts across Hungary, Romania, the UK, and the broader CEE region recognise that the buyer’s payment for goodwill becomes economically worthless if the seller can begin competing the following day. This creates meaningfully more room for enforceable restrictions. But the structural requirements remain demanding, and complacency about this distinction is a common cause of poorly drafted clauses that fail in practice.

‍

The EU Competition Law Ancillary Restraints Framework

There is also, a seldomly addressed, second legal layer in notifiable M&A transactions: the EU competition law framework for ancillary restraints. A non-compete restriction that is “directly related and necessary” to the implementation of a concentration is treated as an ancillary restraint, assessed as part of the merger clearance rather than separately under Article 101 TFEU.

‍

The European Commission’s guidance on ancillary restraints specifies that non-compete clauses of up to three years are generally acceptable where the acquisition involves the transfer of both goodwill and know-how. Restrictions limited to goodwill only support a two-year restriction. Restrictions beyond these periods require specific justification and may be vetoed by the relevant competition authority.

‍

This matters in Romanian and Hungarian M&A transactions because both countries maintain national merger notification thresholds that are lower than EU-level thresholds. A transaction that does not require EU notification can still require Romanian or Hungarian notification, and the Romanian Competition Council may review non-compete provisions as part of its ancillary restraints assessment for those filings. Buyers who have primarily executed Western European transactions sometimes assume that the absence of an EU filing requirement means no regulatory review of the non-compete is necessary. This assumption creates exposure.

‍

Consideration: What the Sale Price Already Covers

In a business sale, the purchase price paid for goodwill constitutes the commercial consideration for the non-compete, provided the restriction is expressly embedded in the share or asset purchase agreement. 

‍

However, where the clause’s duration or scope approaches the upper bound of what the specific transaction supports, explicitly allocating a defined portion of the purchase price to the covenant strengthens the enforceability argument. This creates a documented record that both parties attributed specific commercial value to the restriction, that the seller acknowledged it, and that the buyer’s payment reflected it. In practice, courts might treat this allocation as evidence that the restriction was a genuine commercial negotiation rather than a one-sided imposition, and be more willing to uphold it under scrutiny.

‍

The Four Structural Requirements

Courts across CEE and Western European jurisdictions tend to apply broadly similar proportionality principles when deciding on the validity and enforceability of a  business sale non-compete.

‍

In principle four structural, independently met  requirements are essential:.

‍

1. Duration: Long Enough to Matter, Short Enough to Survive

Two to three years is the defensible standard for a mid-market business sale. This aligns with the EU ancillary restraints safe harbour where goodwill and know-how transfer, with general market practice and EU ancillary restraints guidance across the region, and with the documented practice of CEE M&A advisory firms.

‍

Duration beyond three years is not automatically unenforceable. Courts in the UK and across CEE have upheld restrictions of four and five years in specific factual contexts: complex technical know-how with a long commercial half-life, a founder whose personal relationships covered the entire customer base with no management-level substitutes, or an industry where new entrants require regulatory licensing that takes several years to obtain. But longer durations require specific commercial justification grounded in the transaction facts. The risk of challenge increases materially beyond three years, and courts in both jurisdictions are unlikely to sustain a period that is not demonstrably required to allow the buyer to establish independent customer relationships.

‍

The correct approach is not to default to convention but to determine duration by reference to the specific question: how long would it realistically take, absent the seller’s competitive interference, for the acquired customer relationships to transfer fully to the new owner? A manufacturing business with multi-year supply contracts and a management team that already maintains customer relationships independently is structurally different from a professional services business where every client relationship is held personally by the founder. Duration should reflect this difference, documented in the transaction rationale.

‍

2. Geographic Scope: Operational Footprint, Not Aspirational Coverage

The restriction should map to where the business actually operated at the date of closing, not to where the buyer intends to expand. A Hungarian manufacturing company with no material Romanian revenue cannot support a clause restricting competition across Romania. A regional services business operating within two counties cannot support a nationwide restriction. A business whose entire customer base is domestic cannot support a restriction framed as covering Central Europe.

‍

The operative test is competitive relevance: could the seller, operating from the territory in question, meaningfully compete for the customers, contracts, or market position the buyer acquired? If the answer is no, the restriction is overbroad.

‍

Clauses that fail this test may be voided rather than reduced, particularly where the overbreadth is substantial, although courts retain discretion to modify restrictions in some cases. The reasoning is that a restriction beyond the business’s actual competitive footprint is designed to suppress trade generally, not to protect specific goodwill transfers.

‍

For cross-border HU-RO transactions, which are structurally common in this market, geographic scope should be assessed separately for each jurisdiction, based on that jurisdiction’s actual business operations. A single unified clause may be insufficient where it does not reflect the distinct operational footprint in each jurisdiction. Where the business has significant operations in both countries, the restriction legitimately covers both, but with separate activity and geographic definitions per market. Where operations are concentrated in one country, the other should be excluded or defined precisely by customer or supplier geography rather than political boundary.

‍

3. Activity Definition: Specific Enough to Enforce, Specific Enough to Identify

The activity definition is where most non-competes fail in practice. A prohibition on engaging in “any business similar to” the sold entity, or in “the same sector,” is simultaneously too vague to enforce clearly and too broad to survive proportionality review. The seller cannot identify with certainty what is restricted, the buyer cannot prove a breach without resolving an interpretation dispute first, and courts tend to read contractual ambiguity against the enforcing party.

‍

The correct approach is to define the restricted activity by reference to the specific business operations transferred: the NACE codes or product categories of the sold company, the identified customer segments or geographies served, and the specific services or manufacturing activities that constitute competition with the acquired business. Where the business operates in a defined niche, name the niche. Where it has a specific technology, process advantage, or regulatory position, reference that element directly.

‍

Hungarian courts have specifically voided clauses where the definition gave the enforcing party effective discretion to determine, after signing, what conduct was restricted. In a 2023 decision, a Budapest court struck down a non-compete that prohibited employment at any company “in a business relationship with” a company engaged in similar activities, because this formulation could reach almost any employer in a connected industry, and the employee had no way to assess their own position without asking the claimant. The same logic applies to business sale non-competes: the seller should be able to evaluate correctly whether a specific activity is restricted, without the buyer’s intervention.

‍

4. Consideration: The Commercial Quid Pro Quo

As noted above, the purchase price itself constitutes consideration for the non-compete in most jurisdictions where the restriction is embedded in the SPA. The baseline position is that no separate payment is legally required. But two scenarios warrant explicit allocation of a portion of the purchase price to the covenant.

‍

The first is where duration or geographic scope is at the upper bound of what the transaction supports. Explicit allocation creates a documented record that the parties attributed specific value to the restriction and that the seller accepted it. This is materially more defensible than treating the covenant as a standard SPA clause with no separate commercial weight.

‍

The second is where the transaction structure includes a transition services agreement, an earnout, or a continuing board role for the seller. In this scenario, the non-compete clause interacts with economic incentives created by the post-closing structure, and the interaction should be reviewed deliberately. If an earnout is tied to customer retention over 24 months, the seller’s financial interest already aligns with the buyer’s during that period. The non-compete then primarily governs the post-earnout phase, and its duration should be calibrated accordingly. Treating these provisions in isolation is a structural error that produces gaps in coverage or redundancy that weakens the overall restriction.

‍

Drafting the Behavioral Perimeter: What “Competing” Actually Means

Duration, geography, and activity definition establish the outer boundary of the restriction. The behavioral formulation, what the seller is specifically prohibited from doing within that boundary, determines whether the clause captures the actual risk.

‍

The founder of Spill Bidco held no formal position in either competing business. He had not become an employee, director, or shareholder. What he had done was: make a series of payments to fund a competing Spanish venture; provide supplier names; describe the rival business to third parties as a “sister” company to add credibility; give pricing and supplier advice to a UK competitor; and allow his company’s premises to be used for stock storage. The SPA and investment agreement both prohibited being “engaged, concerned or interested” in a competing business.

‍

The court found that the cumulative payments and support crossed the threshold of being “concerned in” a competing business. One or two isolated payments might not have cleared the threshold alone, the court noted, but the pattern of acts demonstrated active involvement. Facilitating stock storage through his separate company did not breach the covenant: the court treated that as a corporate act rather than the founder’s personal involvement. The distinction is essential.

‍

The practical drafting implication: “engaged in, concerned in, interested in” captures a meaningfully wider range of conduct than “employed by” or “holding equity in.” Going further and listing specific prohibited acts reduces the scope for dispute about whether particular behaviour falls within or outside the restriction. Recommended formulations include: providing financing to; providing advisory services to; introducing customers or suppliers to; holding shares in (other than publicly traded securities below a de minimis threshold); acting as director, officer, or consultant of; and otherwise directly or indirectly supporting a competing business.

‍

This matters in CEE mid-market transactions specifically. Founders in this market operate through personal networks that exist entirely outside formal commercial documentation — supplier relationships built over decades, customer relationships maintained through personal contact, regulatory access tied to the founder’s reputation and relationships. A non-compete after selling a business that prohibits formal employment or equity ownership while leaving informal advisory conduct unrestricted is structurally incomplete for this market.

‍

Multiple Agreements in a Single Transaction

In Spill Bidco the founder in that case was subject to two separate non-compete covenants simultaneously, one in the share purchase agreement (three years) and one in the investment agreement with the private equity TopCo (18 months). Both were found individually enforceable. Both were found to have been breached.

‍

In transactions involving a PE buyer structure, a management co-investment arrangement, or multiple contracting entities, the seller may be bound by restrictions in several documents with varying durations and scopes. What matters is that each restriction should be justifiable on its own commercial terms, courts assess them independently. Where multiple agreements exist, defined terms and enforcement mechanics should be aligned across all documents, each restriction should expressly name the entities for whose benefit it operates, and any overlap or gap in coverage should be deliberate rather than accidental. A restriction that is coherent in the SPA but contradicted or undermined by the investment agreement creates enforcement uncertainty the seller will exploit.

‍

The Severability Clause: Limited Insurance, Not a Safety Net

A severability clause, allows courts to remove unenforceable portions of a restriction while preserving the remainder. Courts may, in certain circumstances, reduce overbroad restrictions, cutting back the duration, geographic scope, or activity definition to something proportionate, rather than voiding the clause entirely. This is commonly described as the blue pencil doctrine.

‍

Including such a boiler plate clause is more than advisable in both Hungarian and Romanian SPAs, however it is no reliable insurance against poor drafting.

‍

Courts are generally reluctant to rewrite commercial agreements between legally represented parties and as such the blue pencil principle is more likely to be applied where the agreement contains a severability clause expressly authorising judicial modification and where the required modification is surgical, reducing a five-year restriction to three years, for example, rather than a fundamental rewrite of the clause’s structure. Where the activity definition is fundamentally misconceived or gives the enforcing party de facto discretion to define its own scope, courts have voided the entire clause rather than reconstructing a valid one.

‍

The safer approach is to draft conservatively on scope and duration, closer to the lower bound of what the transaction commercially supports, rather than to draft aggressively and rely on judicial intervention.

‍

Hungary: Civil Law Framework and Judicial Practice

Hungarian law contains no specific statutory regime for business sale non-competes. The restriction is governed by the Civil Code’s general contract law principles: proportionality, fairness, freedom of contract, and the prohibition on terms that give one party unilateral control over the scope of the restriction after signing.

‍

The employment-context compensation rules (one-third of salary, 24-month cap) do not apply in the M&A context. However, the proportionality standard applies with equal force. Courts assess the specific transaction facts: the seller’s actual competitive footprint, the nature and depth of the goodwill transferred, the duration of the restriction relative to the commercial lifecycle of the acquired customer relationships, and the geographic scope relative to the business’s actual operations.

‍

The documented judicial failure mode in Hungary is overbreadth in activity definition. A 2023 Budapest appeal court decision voided a non-compete entirely because the activity definition was circular and gave the enforcing party de facto discretion to determine its own scope post-signing. The restriction covered employment not only at directly competing companies but at any company with a “business relationship or interest in” such a competing company, a formulation so broad it could reach most of the relevant industry. The court found this inherently invalid: a restriction whose perimeter is defined by one party’s interpretation is not a restriction at all.

‍

For business sale non-competes specifically, the practical guidance from Hungarian judicial practice is: define the restricted activity by reference to specific NACE codes and commercial activities transferred; limit geographic scope to the operating territories documented in the SPA; choose a duration between 24 and 36 months and include transaction-specific rationale for anything beyond two years; and include a severability clause authorising judicial reduction as a residual protection.

‍

Where the transaction involves a PE structure and multiple agreements, all non-compete provisions across all transaction documents should be individually coherent and mutually consistent. The Hungarian Civil Code’s general contract principles do not prevent multiple simultaneous restrictions from operating, but each should independently satisfy the proportionality standard.

‍

Romania: Civil Code, Competition Law, and Cross-Border Structuring

Romania presents the same general civil law framework, proportionality, no statutory cap for business sale non-competes, freedom of contract within the limits of the Civil Code..

‍

The Competition Council Layer

Where a Romanian/cross border  transaction involving Romania meets the national notification thresholds , the non-compete provisions submitted with the filing are reviewed as potential ancillary restraints. Restrictions within the safe harbour — up to three years where both goodwill and know-how transfer, up to two years for goodwill only — are cleared alongside the main transaction. Restrictions outside these parameters may be subject to separate assessment or required modification before clearance.

‍

This is not a theoretical concern. Romanian M&A transactions in the manufacturing, energy, and agrifood sectors that involve regional businesses with combined worldwide turnovers trigger notification requirements. Buyers who assume that the absence of an EU filing means no regulatory review of the non-compete is necessary are structurally exposed. The correct approach is to assess Romanian notification thresholds independently and to structure the non-compete clause within the ancillary restraints safe harbour unless there is specific documented justification for exceeding it.

‍

The Constitutional Right to Work

Romanian civil courts apply the proportionality standard common to most European jurisdictions, but with one additional consideration: the constitutional protection of the right to engage in economic activity. Courts are reluctant to enforce restrictions that would effectively exclude the seller from any productive activity in their area of expertise, even if the clause is correctly scoped in time and geography.

‍

This is not a reason to avoid non-competes in Romanian transactions. It is a reason to define the restricted activity precisely and narrowly, so the seller retains clear pathways to legitimate economic activity outside the restriction’s perimeter. A founder of a Romanian manufacturing business who sells and agrees not to operate in the same product category is not excluded from economic life: they can work in management consulting, in a different manufacturing sector, or in an advisory capacity for non-competing businesses. Articulating these available pathways in the clause itself, or at minimum ensuring they exist implicitly in a narrowly drafted activity definition, strengthens the enforceability argument before Romanian courts.

‍

Cross-Border HU–RO Structuring

For transactions covering both Hungary and Romania, which constitute a significant proportion of Ferdinand’s deal activity, the non-compete should be assessed against both jurisdictions’ requirements independently. A single unified clause may be insufficient where it does not reflect the distinct operational footprint in each jurisdiction.

‍

Where the business has material operations in both countries, the SPA should contain either two jurisdiction-specific non-compete provisions or a single provision with clearly differentiated geographic and activity definitions for each market. The duration can be common; the geographic scope and activity definition should reflect each market’s actual business footprint. Where operations are concentrated in one country, the restriction for the other market should be limited or defined by customer geography, not extended to the full national territory by default.

‍

The practical consideration is also regulatory: if the transaction is notified in Romania, the non-compete provisions will receive explicit regulatory scrutiny. If the transaction is notifiable in Hungary, ancillary restraints are generally covered by the merger clearance. Structuring the clause within safe harbour parameters in both jurisdictions simplifies clearance and reduces the risk that the competition authority requires modification as a condition of approval.

‍

What Enforcement Actually Looks Like

Drafting an enforceable clause is the precondition for meaningful enforcement, but enforcement requires more than a valid restriction. The practical mechanics of pursuing a breach matter as much as the contractual language.

‍

Injunctive Relief and Damages

Courts in both Hungary and Romania provide two primary remedies for non-compete breach: temporary injunctive relief to stop the competing activity, and damages to compensate for the business harm caused by the breach. Injunctive relief is typically the more valuable remedy in practice, stopping the competing conduct before the restriction period expires is commercially more useful than claiming damages after the harm has occurred.

‍

Interim injunctions are available in both jurisdictions where the buyer can demonstrate a credible and imminent threat to their legitimate business interests. The standard is probabilistic: the buyer need not prove breach has occurred, but should show it is sufficiently probable to justify interim relief pending trial. Acting quickly upon becoming aware of the breach is essential, delay in seeking injunctive relief is treated by courts in both jurisdictions as evidence that the harm is not sufficiently urgent to warrant emergency intervention.

‍

For damages claims, the buyer should prove both breach and causality report. In cases where a seller has begun competing before the restriction period expires, causality analysis is genuinely complex: what portion of customer attrition is attributable to the seller’s competitive activity versus normal commercial factors, management quality, or integration disruption? A well-structured clause includes a contractual penalty provision, a pre-agreed sum payable per breach or per month of breach, which eliminates this complexity. Contractual penalties are enforceable under both Hungarian and Romanian civil law as liquidated damages, subject to judicial reduction if the amount is manifestly disproportionate to the actual harm. Setting the penalty at a realistic rather than punitive level reduces the risk of reduction and makes enforcement more straightforward.

‍

The Cumulative Conduct Threshold

The behavioral threshold for breach, particularly for diffuse forms of competitive assistance rather than a formal competing business, follows the logic established in Spill Bidco: isolated or passive contact with a competing business does not constitute being “concerned in” it, but cumulative active assistance does.

‍

In practice, this means that a seller who provides one personal introduction to a former customer occupies a different legal position from one who provides a series of supplier contacts, participates in pricing strategy discussions, publicly associates themselves with a competing venture, and makes multiple financial transfers to the competing entity. The pattern is what matters. For enforcement purposes, this means systematic documentation of the seller’s post-closing conduct, monitoring public statements, trade press mentions, industry contact networks, and supplier references, is commercially valuable even before a breach threshold has clearly been crossed.

‍

Backup Protections: Non-Solicitation, Confidentiality, and Key Employee Agreements

A non-compete agreement addresses one specific risk: the seller entering direct competition. It does not address the full range of post-acquisition exposure in a founder-led mid-market acquisition. Three additional instruments should be structured alongside the non-compete as a coherent protection package.

‍

‍

Non-Solicitation Clauses

Non-solicitation clauses prohibit the seller from actively approaching the acquired business’s customers or employees, regardless of whether the seller has established a competing business. They are generally easier to enforce than broad non-competes because they target specific, identifiable acts of competitive harm, a direct approach to a named customer, an offer of employment to a named employee, rather than broadly restricting market participation.

‍

Non-solicitation provisions should address customer-facing and employee-facing conduct separately, with different temporal parameters where the commercial risk profile warrants it. Customer non-solicitation is typically coextensive with or slightly longer than the non-compete period. Employee non-solicitation can often be extended further, the commercial harm of losing a key employee to a seller-backed venture is not time-limited in the same way that customer relationship risk is. A seller who cannot compete directly but can systematically hire the acquired business’s best people creates a structurally equivalent harm through a different mechanism.

‍

Essential: courts thought the CEE region tend to interpret restrictive non-compete clauses as a method to both split the market (competition law related negative impact) and restrict the relevant employees right to work (constitutional /employment law related impact) so the use of these type of clauses shall be restricted to minimum. 

‍

Confidentiality Provisions

Confidentiality obligations protecting trade secrets, pricing structures, customer lists, and operational processes operate on a different legal basis from non-competes and are generally subject to fewer temporal constraints. A perpetual confidentiality obligation is enforceable in most jurisdictions to the extent it protects information that remains genuinely confidential. A time-limited restriction is appropriate for information with a natural shelf life, a pricing structure that will be superseded within 18 months supports an 18-month restriction, not a permanent one.

‍

Confidentiality provisions are also a useful complement to non-competes in jurisdictions where non-compete enforcement is uncertain. Even where a court declines to sustain the non-compete, a separate confidentiality breach arising from the same conduct may provide a parallel enforcement pathway. The two instruments should be drafted to be mutually reinforcing rather than redundant.

‍

Key Employee Agreements

Key employee retention post-acquisition is not addressed by any clause in the seller’s SPA. Employees are not parties to that agreement. Employee retention after acquisition requires separate instruments: retention agreements with identified key staff, often structured with a retention bonus vesting over 12 to 24 months post-closing, sometimes funded in part by the seller as a condition of the transaction closing.

‍

Identifying which employees carry the relationships and operational knowledge that the acquisition price reflects, and securing those employees independently of the seller’s continuing presence, is structurally more reliable than assuming the non-compete will prevent the relevant harm. A seller who does not actively compete but whose departure triggers the resignation of three key employees achieves the same economic effect without technically breaching any restriction.

‍

The Gap That Most Guidance Misses: A Valid Clause Is Not Enough

The most consistently underweighted point in non-compete guidance, and in most deal structures, is that a correctly drafted restriction is, by itself, insufficient to protect the goodwill the buyer paid for.

‍

Consider the mechanics. The non-compete prohibits the seller from rebuilding the customer relationships they transferred. What it does not do is ensure those relationships successfully transfer. If the business is deeply owner-dependent, the seller is the primary contact for the five largest accounts, the regulator’s interlocutor for the licence driving 40% of revenue, the only person who has met the three critical suppliers, then the non-compete restriction holds, and the underlying value it was designed to protect quietly migrates away regardless. The restriction prevented the seller from competing. No one structured the transfer of what the seller agreed not to compete for.

‍

This is one of the most consistent post-acquisition problems in CEE mid-market transactions. The non-compete clause is signed and filed. The transition plan is verbal, or covers a 30-day handover period that is not adequate for relationships built over a decade. The seller honours the restriction. The customer base nevertheless erodes over 18 months, because the customer relationships were personal and the acquisition process included no mechanism for their structured transfer. This is among the primary acquisition failure reasons in owner-managed mid-market businesses.

‍

The Correct Sequence: DD Through to Integration

The correct structure is a sequential one where each step informs the next. Due diligence identifies the owner-dependency profile in granular detail: which customer relationships are personal, which are contractual, which can be transferred with a structured introduction, and which require ongoing founder involvement over an extended period. This informs valuation: revenue streams that are genuinely at risk in a transition are not valued at the same multiple as contracted, management-independent revenue. It then informs deal structure, where the non-compete, earnout, transition services agreement, and key employee plan each address a distinct dimension of the same underlying risk.

‍

The non-compete agreement prevents the seller from rebuilding elsewhere. The earnout aligns the seller’s financial interest with successful owner transition after sale. The transition services agreement specifies the mechanism and timeline for introducing customers to the new owner. The key employee retention plan addresses the staff who carry the relationships the seller cannot personally introduce. An acquisition integration plan that treats these as separate workstreams rather than an integrated response to a single risk is not a complete post-merger integration plan.

‍

Understanding merger integration risks in CEE mid-market transactions also requires acknowledging that standard integration playbooks, derived from larger, more institutionally managed Western European businesses, may not apply directly. In Hungarian and Romanian owner-managed businesses, informal authority structures, supplier relationships, and regulatory relationships held personally by the founder require a tailored post-acquisition integration strategy that addresses the actual dependency profile, not the formal org chart. The org chart will show a management team. The dependency map will show which of those managers have ever spoken to a major customer without the founder being present.

‍

A post-merger integration checklist that does not include a non-compete review, a detailed transition plan, and a key employee retention framework as integrated and sequenced elements is structurally incomplete for mid-market transactions in this market. Customer retention after acquisition is not a natural outcome of a legally valid non-compete. It is the result of a structured process that begins in the due diligence phase and runs through the first 18 to 24 months of ownership.

How Ferdinand Approaches Non-Compete Structuring in CEE Transactions

Ferdinand Investment Partners advises buyers on mid-market transactions across Hungary, Romania, and the broader CEE region. On buy-side mandates, deal structuring is part of the engagement, not just identifying risk, but determining how it is allocated between the parties and how the acquisition agreement reflects that allocation.

‍

Non-compete structuring is part of that work. We review the seller’s actual competitive footprint, assess the owner-dependency profile identified during due diligence, and work with local legal counsel in both jurisdictions to determine the duration, geographic scope, and activity definition that the specific transaction supports and that local courts are likely to sustain. The commercial structuring and the legal drafting are distinct disciplines, the first informs the second, and both are required to produce a clause that functions as intended. A commercially grounded restriction that is legally incoherent fails on enforcement. A legally precise clause that does not reflect the transaction’s actual risk profile does not work in practice.

‍

This article was produced in partnership with Nagy and Associates, one of Ferdinand’s legal advisory partners for CEE transactions. Nagy and Associates is a full-service law firm based in Transylvania, advising clients in Romanian, Hungarian, English, and German across a broad range of corporate and commercial mandates — with particular depth in the legal dimensions of cross-border transactions in the region.

Non-Compete Agreement for Selling a Business: FAQ

‍

How long can a non-compete agreement last when selling a business in Hungary or Romania?

In Hungary, there is no statutory cap on duration for a non-compete clause in a business sale agreement, the restriction is governed by the Civil Code’s proportionality standard rather than the Labour Code’s fixed limits. In practice, periods of 24 to 36 months are the defensible standard for mid-market transactions, and periods beyond three years require specific commercial justification: industry dynamics with unusually long customer relationship cycles, a seller whose technical know-how has a multi-year shelf life, or a business where the founder personally holds every material customer relationship without management-level substitutes. In Romania, the same general framework applies, no statutory cap for business sale restrictions, courts assess duration against the time commercially necessary for the buyer to establish independent customer relationships. The EU competition law ancillary restraints safe harbour, which covers both jurisdictions, supports up to three years where both goodwill and know-how transfer, and up to two years for goodwill only. Structuring within these parameters simplifies regulatory clearance in notifiable transactions and reduces the risk of independent competition authority review.

‍

What makes a non-compete clause unenforceable in a business sale?

The most common failure modes are: geographic scope exceeding the business’s actual operating area at closing; an activity definition so broad or vague that the seller cannot identify what is restricted without the buyer’s interpretation; duration that is not commercially justified by the specific transaction facts; and a behavioral formulation that covers only formal employment or equity ownership while leaving material forms of competitive assistance unrestricted. In Hungary and Romania, courts have also voided clauses where the activity definition gave the enforcing party effective discretion to determine its own scope post-signing, treating this as inherently invalid because it is not a restriction at all, but a unilateral right. A clause that prevents the seller from engaging in any productive economic activity in their area of expertise, rather than targeting the specific business sold, is likely to fail on proportionality grounds in both jurisdictions. The practical test in both markets is whether the seller can assess their own position, whether a specific act or commercial arrangement is restricted, without needing to ask the buyer.

‍

Does the seller need to be paid separately for agreeing to a non-compete in a business sale?

No, as a general rule: in Hungary, Romania, and the UK, the purchase price paid for the business, including the goodwill premium, constitutes adequate consideration for the non-compete where the restriction is expressly embedded in the SPA. However, where duration or geographic scope approaches the upper bound of what the transaction can commercially support, allocating a defined portion of the purchase price explicitly to the non-compete covenant substantially strengthens the enforceability argument. It creates a documented record that both parties attributed specific commercial value to the restriction and that the seller accepted it knowingly. This allocation should appear in the SPA itself, not in a side letter or recital. For transactions structured with an earnout or transition services arrangement, review the interaction between those provisions and the non-compete: financial incentives that apply during the restriction period can reinforce it; those that apply after the restriction expires may create a cliff that weakens the non-compete’s commercial logic during the final period.

What is the difference between a non-compete and a non-solicitation clause in a business sale, and which is easier to enforce?

A non-compete restricts the seller from operating a competing business within a defined geography and period. A non-solicitation clause restricts the seller from approaching identified customers, employees, or suppliers, regardless of where the seller’s post-closing activities are based or whether those activities constitute competition. Non-solicitation clauses are generally easier to enforce because they target specific, identifiable acts of harm — a direct approach to a named customer, an employment offer to a named employee — rather than broadly prohibiting market participation. They are also less exposed to proportionality challenge, because they do not prevent the seller from earning a living; they only prevent the seller from targeting the specific relationships that were transferred at closing. Both provisions should appear in any well-structured business sale agreement as they address different risk scenarios. A seller who does not establish a competing business but systematically approaches the acquired company’s customer base is causing material harm that only the non-solicitation clause, not the non-compete, would address.

Can a court modify an overbroad non-compete rather than striking it entirely?

Courts may both reduce overbroad restrictions, cutting back the duration, geographic scope, or activity definition to something proportionate,  or, if the relevant restriction is considered as extremely harmful, void the clause entirely. In practice, this power is applied selectively and is not reliable as a drafting safety net. Courts in both jurisdictions are generally reluctant to rewrite commercial agreements between legally represented parties. The blue pencil as explained above, is more likely to be applied where the agreement contains a severability clause expressly authorising judicial modification and where the required modification is surgical. Where the activity definition is fundamentally misconceived or gives the enforcing party de facto discretion to define its own scope, courts in both Hungary and Romania have voided the entire clause rather than reconstructing a valid one. The correct approach is to draft conservatively: a restriction that is narrow enough to survive scrutiny is commercially more valuable than one that is broad enough to require court modification.

What happens if the seller remains involved post-closing as a director or advisor?

The seller’s continuing involvement through a board role, transition services agreement, or advisory arrangement does not suspend or modify the non-compete covenant unless the SPA explicitly provides for this. Spill Bidco is instructive here: the founder remained on the board of the acquired group as a non-executive director throughout the period when he was providing assistance to competing businesses. His continuing involvement did not affect the court’s analysis of breach — the non-compete covenant operated independently of the board role.

Where the seller retains a formal role post-closing, the non-compete and the service or advisory agreement should be reviewed together for consistency. An advisory agreement that creates an obligation on the seller to identify market opportunities may inadvertently create conflict with the non-compete’s prohibition on being “concerned in” competing businesses. The transition services arrangement should define specifically what assistance the seller is providing, for whom, and in what capacity, and should expressly confirm that the seller’s obligations under the non-compete continue in full during and after the transition period. A transition services agreement that is silent on the non-compete creates interpretive risk that the seller will exploit.

How does owner dependency identified during due diligence affect non-compete design?

Owner dependency findings are the most direct input into non-compete structuring. If due diligence establishes that the seller personally holds all five largest customer relationships, that the key regulatory licences are issued on the basis of the founder’s personal accreditation, and that the three critical supplier relationships exist entirely through the founder’s network, then the non-compete should be structured to prevent the seller from immediately reconstructing that competitive position elsewhere. Duration should cover the period required to transfer those relationships under the transition plan. Geographic scope should map to wherever those customers or suppliers operate. Activity definition should specifically cover the product lines and customer segments where the owner-dependency is concentrated.

Where owner dependency is severe, the founder is, operationally, the business rather than its manager, the non-compete is a necessary but not sufficient protection. The deal structure should also include an earnout tied to customer retention over 18 to 24 months, a substantive transition services agreement specifying the mechanism and timeline for relationship transfer, and a key employee retention plan for the staff who support the founder’s customer-facing activities. The non-compete prevents the seller from rebuilding the value that was transferred. The integration structure determines whether that value successfully transfers in the first place. One without the other leaves the buyer holding a legally valid restriction over goodwill that no longer exists.
