The Sale and Purchase Agreement (SPA): Key Clauses That Protect the Seller

Once a buyer and seller agree a price, the deal moves to the document that governs everything: the Sale and Purchase Agreement (SPA). This is where the real negotiation often lies, because the terms behind the price determine what a seller actually keeps — and what risk they carry after completion. This guide walks through the SPA clauses that matter most from a seller's perspective.

This is general information, not legal advice. An SPA must be drafted and negotiated by qualified lawyers for your specific transaction and jurisdiction.

Why the SPA matters as much as the price

Two deals at the same headline price can leave sellers in very different positions depending on the SPA. A seller who accepts a strong price but gives sweeping warranties, weak limitations and a large holdback may end up worse off than one who accepts slightly less with tighter, better-protected terms. Reading and negotiating these clauses carefully is where experienced advisers and lawyers protect value.

The price mechanism

The SPA sets out not just the number but how the price is calculated and adjusted:

• Completion accounts vs. locked box. In a completion accounts deal, the price is adjusted after closing based on the actual net debt and working capital at completion. In a locked box deal, the price is fixed by reference to a recent balance sheet, with protections against value leaving the business in the meantime. Each has trade-offs for certainty and timing.
• Net debt and working capital. Definitions here move real money. Sellers should scrutinise how debt-like items and the "normal" level of working capital are defined.
• Deferred consideration and earn-outs. If part of the price is deferred or contingent, the mechanics and protections matter enormously — see our guide to earn-outs and deferred consideration.

Warranties

Warranties are statements of fact the seller makes about the business — that the accounts are accurate, there is no undisclosed litigation, key contracts are in force, and so on. If a warranty turns out to be untrue and the buyer suffers loss, the buyer can claim. Warranties are heavily negotiated because they define the seller's exposure. Sellers seek to:

• Qualify by knowledge and materiality where appropriate (for example, "so far as the seller is aware").
• Disclose fully. Anything properly disclosed in the disclosure letter and data room generally cannot later be the basis of a warranty claim — so thorough disclosure is a seller's best protection.

Indemnities

An indemnity is a promise to reimburse the buyer, on a pound-for-pound basis, for a specific identified risk (for example, a known tax exposure or a particular dispute). Indemnities are more onerous than warranties because they usually sidestep the usual limitations. Sellers should resist broad, open-ended indemnities and confine them to genuinely specific, identified matters.

Limitations on liability

This is the seller's core protection package, and among the most important parts of the SPA:

• Financial caps. An overall cap on total liability (often a percentage of the price), plus lower caps for certain claim types.
• De minimis and baskets/thresholds. Small claims below a threshold are excluded, and claims only become payable once they exceed an aggregate basket — preventing a stream of trivial claims.
• Time limits. Deadlines by which claims must be brought (commercial warranties typically expire sooner than tax warranties).
• Other exclusions. Carve-outs for matters disclosed, provided for in the accounts, or arising from changes in law after completion.

Getting these limitations right is often worth as much to a seller as several percentage points on the price.

Conditions, covenants and security

• Conditions precedent. Anything that must happen before completion (regulatory approvals, consents). Sellers want these to be limited and achievable.
• Restrictive covenants. Buyers usually require non-compete and non-solicit undertakings. These should be reasonable in scope, duration and geography.
• Security for the buyer. Buyers may seek a retention/holdback, an escrow, or warranty and indemnity (W&I) insurance. W&I insurance can be attractive to sellers because it can allow a cleaner exit with less residual liability.

The takeaway

The SPA is where a sale is truly won or lost. Price mechanics, warranties, indemnities and — above all — the limitations on liability determine what you keep and what risk you carry after you have handed over the keys. Never treat the SPA as a formality after agreeing the number. RV Capital works alongside your legal counsel to negotiate the commercial terms of the SPA in your favour.
