Post-sale restrictive covenants may limit competition, solicitation or other activity after completion. Their enforceability and appropriate scope depend on the facts and applicable law. Review what the buyer needs to protect and what the seller intends to do next before agreeing broad restrictions.
Distinguish a business sale covenant from an employment restriction. Identify prohibited activities, customers, staff, territory and duration, including exceptions for retained businesses or passive investments where appropriate. Avoid assuming that a longer restriction is automatically stronger or that every negotiated clause will be enforceable.
Identify the business interest being protected
Describe the goodwill, customer relationships or confidential know-how the buyer is acquiring. Then ask which post-sale activities could materially undermine that purchase. A restriction should be analysed against the actual business and applicable law, not copied from an employment contract because the wording is familiar. The appropriate scope and enforceability require advice on the transaction's facts and jurisdiction.
List the seller's plans after completion, including retained businesses, consultancy, investments and existing outside roles. Raise these before agreeing the headline bargain if they matter commercially. A broad prohibition on any involvement in a related industry may interfere with activities the seller assumed were unaffected. Specific disclosure allows the parties to negotiate clear boundaries rather than discover the conflict after the price and structure are fixed.
Read each type of restriction separately
Distinguish competing, soliciting customers, dealing with customers, recruiting staff and using confidential information. These clauses can prohibit different conduct even where they appear under one heading. Check definitions of the business, customers, employees and connected persons. An exception in one clause should not be assumed to apply to every other restriction unless the document makes that clear.
Review territory and duration against the interest and evidence. An online business may need a different analysis from a local operation, but internet access does not automatically justify a worldwide restraint. Do not assume a longer period creates stronger protection. Obtain advice on proportionality and the consequences of overbroad drafting rather than expecting a court to repair an unsuitable clause later.
Test ordinary future scenarios before signing
Work through concrete examples: the seller receives an unsolicited enquiry from a former customer, buys a small passive investment or continues a disclosed service line. Ask whether each action is prohibited, permitted or requires consent. Use the intended wording rather than the negotiating team's general reassurance. The examples expose differences between non-solicitation and non-dealing restrictions that may be commercially significant.
If an exception is agreed, define it precisely enough to remain useful when management changes. Identify the retained activity or investment threshold as appropriate to the bargain. Check whether the exception applies to entities through which the seller may act. Avoid an arrangement in which ordinary permitted work depends on informal goodwill from one buyer representative who may leave shortly after completion.
Coordinate restrictions with other transaction documents
Review employment, consultancy, shareholder and confidentiality documents alongside the sale agreement. The seller may be subject to overlapping provisions with different periods or triggers. A restriction starting on completion is different from one starting when employment later ends. Keep those timelines visible and obtain advice on the combined effect rather than reviewing each document in isolation.
Use Earn-out terms: points to negotiate where an earn-out depends on the seller's continuing role and IP checks before buying a company where confidential know-how or IP is part of the value. The general sale-responsibilities guidance from nibusinessinfo provides transaction context; it is not a ruling that any particular covenant is enforceable. [1] Record the legal questions requiring tailored review instead of presenting a standard duration as automatically valid for every sale.
For Business sale document review, provide the proposed restrictions, sold business description and the seller's future plans. Ask for a scenario-based explanation and drafting aligned with the legitimate commercial objective. Keep the agreed exceptions and consent process accessible after completion. If a possible breach arises, preserve evidence and seek advice promptly before making public allegations or contacting customers in a way that creates further confidentiality or commercial problems.
Examine restrictions against the seller's future plans
List the activities the seller expects to undertake after completion, including employment, consultancy, investment and any retained business. Compare each realistic activity with the proposed wording and discuss uncertain cases before signing. A broad assurance that the seller can still work in the industry may not explain how the actual restriction applies.
Record any agreed exclusions precisely and check them against confidentiality, employee and customer provisions elsewhere in the documents. Consider what happens if the buyer later changes the acquired business or if the seller's new role develops over time. Specialist advice should address the particular facts and jurisdiction. A practical scenario list helps that advice focus on the decisions the seller will actually face.
Illustrative scenario
A founder sells one service line but intends to continue a separate consultancy. The draft restriction covers all consulting work. The parties define the sold business and assess a proportionate restriction, so the seller can understand whether the retained activity is permitted before accepting the deal.
Preparation checklist
- Define the goodwill or interest intended to be protected.
- Compare restrictions with the seller’s future plans.
- Check activities, people, territory, duration and exceptions.
- Obtain advice on proportionality and enforceability.
Frequently asked questions
Are business sale covenants identical to employment restrictions?
No. Context matters, and overlapping documents may have different purposes and triggers. Obtain advice on the actual transaction rather than copying an employment clause into a sale agreement.
Does a longer restriction give better protection?
Not automatically. Scope, duration and enforceability need assessment against the business interest and applicable law. Overbroad drafting can create problems rather than additional certainty.
Should the seller disclose a planned new business?
Raise material future activities before signing so their treatment can be negotiated clearly. Do not rely on an informal assurance that a broadly worded clause will never be used.
What examples should we test?
Consider unsolicited customer approaches, retained services, recruitment, consultancy and passive investments. Read each restriction and exception against the scenario instead of assuming all clauses prohibit the same conduct.
