Business Sale Agreements
The Business Sale Agreement is the principal legal document governing the sale of a business. It records what is being sold, the purchase price, each party's obligations and how legal and commercial risk will be managed before, during and after completion. We draft and negotiate Business Sale Agreements that accurately reflect the agreed transaction while protecting your position throughout the sale.

What is a Business Sale Agreement?
A Business Sale Agreement is the contract that turns the parties' commercial understanding into binding legal obligations. Depending on the transaction, it may document an asset sale, under which specified assets and liabilities are transferred, or a share sale, under which ownership of the company carrying on the business changes.
The agreement identifies the parties, defines precisely what the buyer is acquiring and records the price and payment arrangements. It also deals with the information the buyer has relied on, the protection available if that information is inaccurate, the steps required for completion and any obligations that continue afterwards.
Its terms should reflect the structure, value and particular risks of the transaction. A document prepared for one sale will rarely be suitable for another without careful review. The agreement must work alongside the Heads of Terms, due-diligence findings, disclosure letter, tax advice, finance arrangements and the documents transferring individual assets or shares.
The agreement is not simply a record of the deal. It is the principal mechanism for deciding which party bears a risk if an assumption proves incorrect, a liability emerges or an obligation is not performed.
If you are planning the wider transaction, see our guidance on selling a business or buying a business.
Why the Agreement Matters
A business sale involves more than transferring ownership in exchange for payment. The agreement connects the commercial bargain with the legal steps needed to deliver it and sets out what happens if the transaction does not proceed as expected.
-
Records exactly what is being sold
Clear definitions and schedules distinguish the assets, shares, rights and liabilities included in the deal from anything being retained or excluded. -
Sets the purchase price and payment terms
The agreement explains how the price is calculated, when it must be paid and what security or adjustment applies where payment is deferred or dependent on future performance. -
Allocates legal and commercial risk
Warranties, disclosure, indemnities, covenants and liability limitations determine the protection available if a problem exists or emerges after completion. -
Controls completion
Conditions, deliverables and payment mechanics are coordinated so that control, title and funds pass in the intended order. -
Defines continuing obligations
The contract can govern handover support, restrictive covenants, outstanding payments, confidentiality, claims and other matters long after the completion date.
How our Business Sale Agreement solicitors help
We connect the drafting and negotiation of the agreement with the commercial objectives of the sale. Our role is to identify the issues that matter, explain the available options and secure workable terms without losing sight of the timetable.
Reviewing the transaction and Heads of Terms
We review the proposed structure, agreed price, parties, funding, timetable and any conditions already recorded. Early review can identify provisions that require clarification before they become difficult to renegotiate.
Drafting, reviewing and negotiating the agreement
We prepare or review the Business Sale Agreement, incorporate the due-diligence findings and negotiate the warranties, indemnities, liability limits, payment protections and operational provisions relevant to your position.
Completion and post-completion support
We coordinate signing, completion documents, funds and transfer formalities, then help manage registrations, notifications, retained obligations, deferred payments and other steps that continue after the sale.
What is included in a Business Sale Agreement?
The precise contents depend on whether the transaction is an asset sale or share sale and on the nature of the business. The following provisions commonly form the framework of the agreement.
- Parties
Identifies who is selling, who is buying and whether guarantors, covenantors or other parties must also assume obligations. - Assets or shares
Defines the legal and beneficial interests being transferred and, in an asset sale, separates included assets and assumed liabilities from excluded items. - Purchase price
Records the amount payable, its allocation or calculation, the payment timetable and any retention, adjustment, earn-out or deferred element. - Completion
Lists the documents, approvals, payments and practical actions needed to complete the sale and deals with any conditions that must be satisfied first. - Warranties
Records contractual assurances about the business, company or assets and provides a basis for a claim if an assurance is inaccurate and loss results. - Disclosure
Allows the seller to qualify warranties by giving the buyer sufficiently clear information about exceptions before completion. - Indemnities
Allocates identified risks through a contractual promise to compensate for specified losses or liabilities, subject to the negotiated wording. - Restrictive covenants
May restrict the seller from competing with the transferred business, soliciting customers or staff, or interfering with commercial relationships, within enforceable limits. - Liability limitations
Sets financial thresholds and caps, time limits, exclusions, conduct requirements and claim procedures that control the seller's continuing exposure. - Post-completion obligations
Deals with handover, records, access, announcements, releases, registrations, further assurance and obligations connected with later payments.
Purchase price and payment
Agreeing a headline price does not settle how much will ultimately be paid or when the seller will receive it. The Business Sale Agreement must translate the valuation and commercial bargain into a payment mechanism that can be applied without ambiguity.
Fixed price
A fixed price offers simplicity, but the parties must still decide what happens to cash, debt, stock, work in progress and other balance-sheet items. The agreement should state whether any adjustment is permitted and specify the payments to be made at completion.
Deferred consideration
Where part of the price is paid after completion, the seller takes the risk that the buyer may pay late or become unable to pay. The agreement can address payment dates, interest, security, guarantees, acceleration following default and whether the buyer may set off claims against instalments. Buyers will want to preserve legitimate remedies without creating uncertainty over funding.
Earn-outs
An earn-out links part of the price to the future performance of the business. It can bridge a valuation gap, but only if the relevant targets, accounting policies, calculation period and control of the business are defined carefully. The seller may seek protections against actions that depress the earn-out; the buyer will require sufficient freedom to operate the acquired business.
Completion accounts and price adjustments
Completion accounts can adjust the price by reference to matters such as cash, debt or working capital at completion. The agreement should specify the accounting principles, preparation process, access to information, review period and method for resolving disputes. A locked-box or other fixed-price mechanism requires different protections, including controls over value leaving the business before completion.
A payment mechanism should produce a predictable result. Definitions, examples and an agreed hierarchy of accounting rules can prevent the same commercial formula being interpreted in different ways.
Warranties, disclosure and indemnities
Due diligence helps the buyer investigate the business, but the buyer will not normally rely on investigation alone. The agreement uses warranties, disclosure and indemnities to allocate the consequences of inaccurate information and identified risks.
What are warranties?
Warranties are contractual statements about matters such as ownership, accounts, contracts, employees, disputes, intellectual property, property, compliance and tax. They require the seller to test the accuracy of information being given and can give the buyer a contractual remedy if a warranty is untrue and the legal requirements for a claim are met.
The warranties should be proportionate to the business and transaction. Buyers need meaningful protection covering the matters that affect value. Sellers should avoid giving assurances that are unnecessarily broad, outside their knowledge or inconsistent with the agreed scope of the sale.
Why disclosure matters
The disclosure process allows the seller to identify exceptions to the warranties before completion. Disclosures are normally recorded in a disclosure letter supported by a bundle of documents. Effective disclosure can prevent a buyer from later claiming that a matter was not revealed, while inadequate or unclear disclosure may leave the seller exposed.
Disclosure is not a substitute for organised preparation. Information provided during legal due diligence must be reviewed against the actual warranties, because placing a document in a data room does not necessarily achieve the contractual standard of disclosure.
Why indemnities may be required
An indemnity is commonly used for a specific risk already identified, such as a known dispute, tax exposure or unresolved contractual liability. Its scope, causation, recoverable loss, mitigation, exclusions and relationship with the general liability limitations must be negotiated carefully. The label alone does not determine how a provision will operate.
Buyers need protection that is usable if a material problem emerges. Sellers need the subject matter, scope and duration of that protection defined so that the sale does not create unlimited or unpredictable exposure.

Limiting seller liability
A seller will usually remain exposed to potential claims after completion. Negotiating the limits on that exposure is therefore as important as negotiating the warranties and indemnities themselves. The appropriate protection depends on the sale price, the risks identified, the bargaining position of the parties and any insurance or security arrangements.
Financial thresholds and caps
The agreement may disregard individual claims below an agreed minimum and require qualifying claims to exceed an aggregate threshold before recovery is available. Overall caps can limit liability to an agreed amount, while different caps may apply to general warranties, tax matters, specific indemnities and fundamental issues such as title.
Time limits
Claims may have to be notified within a contractual period, with different deadlines for general, tax and other liabilities. The agreement should state what a valid notice must contain and whether proceedings must begin within a further period. Unclear notice provisions can create disputes before the underlying claim is considered.
Claim procedures and exclusions
The seller may seek control or participation rights where a third party brings a claim. Other provisions can address mitigation, recovery from insurers or third parties, changes in law, matters already disclosed or reserved in the accounts, contingent liabilities, double recovery and conduct by the buyer after completion.
A commercial negotiation
Liability limitations must be considered together rather than in isolation. A low cap may offer little protection if important claims are excluded from it; a short limitation period may be weakened by an imprecise notification requirement. We assess the complete package and explain where the remaining exposure lies.
The agreement should leave the seller with a defined, manageable level of continuing risk and give the buyer appropriate remedies for matters that genuinely affect the acquired business.
Completion and post-completion
The agreement must provide a practical route from signing to the transfer of ownership. Signing and completion may occur together, or completion may be delayed until conditions such as regulatory consent, landlord approval, finance or another transaction requirement have been satisfied.
Completion mechanics
The completion provisions coordinate the delivery of signed documents, release of funds, transfer of shares or assets, board approvals, resignations, records, keys, passwords and other items needed to place the buyer in control. They should also explain what happens if one party cannot complete or a condition remains outstanding.
Transfer documents and third-party consents
An asset sale may require separate assignments, novations, property documents, intellectual-property transfers and arrangements for employees, stock and customer payments. Contracts cannot always be transferred by the sale agreement alone, so the parties may need third-party consent or interim arrangements.
See our guides to what happens to contracts when a business is sold, commercial lease assignments and TUPE and employee transfers.
Continuing obligations
Completion does not necessarily end the relationship. The agreement may govern deferred consideration, earn-out reporting, collection of historic debts, access to records, handover support, announcements, confidentiality, restrictive covenants, release of guarantees and assistance with claims or regulatory matters.
Registrations, notices and filings must also be completed within the relevant timetable. We can coordinate these steps through our completion and post-completion support service.
A detailed completion checklist should allocate responsibility for every payment, document and notification. This reduces last-minute uncertainty and helps prevent important obligations being overlooked once control has changed.

These answers provide a general overview. The correct drafting and negotiation strategy depends on the structure and circumstances of the transaction.
What does a Business Sale Agreement do?
It records the terms on which a business, its assets or shares are sold. It defines the subject of the sale, price, payment arrangements, completion obligations, contractual protections and the allocation of risk before and after completion.
Who prepares the Business Sale Agreement?
In many transactions the buyer's solicitor prepares the first draft, particularly in a share sale, although this is not an absolute rule. The seller's solicitor reviews and negotiates the draft, prepares disclosures and ensures that it reflects the commercial terms. The parties may agree a different drafting responsibility depending on the transaction.
Can a Business Sale Agreement be negotiated?
Yes. Its commercial and legal terms are normally negotiated. Common areas include the definition of what is sold, payment mechanics, conditions, warranties, indemnities, disclosure, restrictive covenants, liability limitations and the documents required at completion.
What are warranties in a Business Sale Agreement?
Warranties are contractual statements about the business, company, assets or transaction. They help the buyer assess risk and may support a contractual claim if a statement is untrue and loss results. Their scope and the applicable limitations should be negotiated for the particular sale.
What is a disclosure letter?
A disclosure letter sets out information that qualifies the warranties. It usually contains general disclosures and specific disclosures supported by documents. A seller should ensure disclosures are accurate and satisfy the standard required by the agreement; a buyer should assess how each disclosure changes the protection offered by the warranties.
What are indemnities?
Indemnities allocate specified risks by requiring one party to compensate the other for defined loss or liability. They are often requested where due diligence identifies a particular exposure. Their effect depends on the exact drafting, including scope, exclusions and any liability limitations.
Can a seller remain liable after completion?
Yes. Liability may continue under warranties, indemnities, restrictive covenants, deferred-payment provisions, tax covenants, guarantees or other continuing obligations. The agreement should set appropriate caps, time limits, exclusions and claim procedures and should identify any obligations that are intended to continue without those limits.
When should a Business Sale Agreement be drafted?
Drafting commonly begins once the principal commercial terms and transaction structure are sufficiently clear. Legal advice should be taken earlier, ideally before Heads of Terms are finalised, because decisions made at that stage can affect the price mechanism, due-diligence process, risk allocation and timetable.
How long does it take to negotiate a Business Sale Agreement?
The timetable depends on the size and complexity of the business, quality of its records, due-diligence findings, funding, third-party consents and the number of issues requiring negotiation. A straightforward sale may progress within several weeks, while a complex or heavily negotiated transaction may take several months.
How much does a Business Sale Agreement cost?
Cost depends on whether the matter is an asset or share sale, the transaction value, drafting responsibility, quality of the business records, extent of due diligence, number of warranties and disclosures, price mechanism and level of negotiation. We can explain the likely scope and provide cost information after reviewing the proposed transaction. Read our guide to the legal costs of selling a business.
