Navigating a share purchase agreement can feel daunting. Whether you’re acquiring a company or selling your stake, the fine print matters. Every clause, warranty, and schedule can affect your financial position, future liabilities, and even your reputation. At The Law Firm Group, we understand how crucial it is to get things right. In this article, we’ll walk you through the essential considerations for share purchase agreements in 2026, so you can approach your transaction with confidence and clarity.
Understanding the Share Purchase Agreement
At its core, a share purchase agreement (SPA) sets out the terms under which shares in a company are bought and sold. It’s a binding contract that determines exactly what’s being transferred, for how much, and under which conditions. The SPA covers far more than just the purchase price—it also addresses the rights and obligations of both parties, details on completion, and what happens if things don’t go as planned.
In England and Wales, the SPA is central to the transfer of company ownership. It ensures that both buyer and seller are clear about their responsibilities and the implications of the transaction. A well-drafted SPA can prevent costly disputes and provide a solid foundation for the business moving forward.
Pro tip: It’s wise to have the SPA reviewed by a legal professional with experience in English company law. The Law Firm Group can help ensure your agreement is robust and tailored to your needs.

Price, Payment, and Completion Mechanics
The purchase price is usually the headline issue, but there’s more to it than simply agreeing a figure. The SPA will define how the price is calculated, when and how it’s paid, and whether it’s subject to any adjustments post-completion. Common mechanisms include locked box or completion accounts, which can significantly influence the final amount exchanged.
Payment terms might involve a lump sum on completion, deferred payments, or even earn-outs dependent on future company performance. The SPA should also specify what happens if the buyer is unable to pay, or if the seller fails to deliver the shares as agreed.
Completion is another key area: this is when the legal ownership of the shares changes hands. The SPA must clearly set out the steps to be taken at completion, including the delivery of share certificates, updating of the company register, and release of funds.
Pro tip: Payment structures can be complex and might have tax implications. Get tailored advice from The Law Firm Group to optimise your transaction and avoid unexpected pitfalls.
Warranties, Indemnities, and Disclosures
Warranties and indemnities make up the backbone of risk allocation in any SPA. Warranties are statements made by the seller about the company’s affairs—covering everything from accounts and contracts to compliance and assets. If a warranty turns out to be false, the buyer may be able to claim damages. Indemnities, on the other hand, are specific promises to compensate the buyer if a particular risk materialises.
The disclosure letter sits alongside the SPA and is the seller’s opportunity to qualify or limit the warranties. It sets out any known issues so the buyer can make an informed decision. The interplay between warranties, indemnities, and disclosures is nuanced and can have significant financial consequences.
Pro tip: Properly drafted warranties and a thorough disclosure process can protect both parties. Speak to The Law Firm Group to ensure your position is safeguarded.

Conditions Precedent and Post-Completion Obligations
SPAs often include conditions precedent—matters that must be satisfied before completion takes place. These might involve regulatory consents, third-party approvals, or the repayment of debts. If these conditions aren’t met, the transaction may not proceed.
Post-completion obligations are equally important. These can include restrictions on the seller (such as non-compete clauses), transitional assistance for the buyer, or the transfer of key contracts. Ensuring these obligations are clear and enforceable is vital for a smooth transition and to protect the value of the business acquired.
Pro tip: Don’t overlook the importance of conditions and post-completion steps. We can help you anticipate practical issues and ensure nothing is missed.
Employee Matters and Pensions
Staff are often a company’s most valuable asset, and their rights and entitlements are a central concern in any SPA. The agreement must address how employees will be treated, whether any changes to terms are anticipated, and how any existing or potential claims will be handled. In England and Wales, employment law can be complex, especially where pensions are involved.
If the company operates a pension scheme, the SPA should detail how liabilities are dealt with and the steps for notifying or consulting with employees where required. Failing to address these issues can lead to claims, disruption, or even regulatory penalties.
Pro tip: Early consideration of employee and pension matters can prevent complications later. The Law Firm Group’s employment team can advise on all related aspects.

Confidentiality, Restrictive Covenants, and Dispute Resolution
Protecting confidential information and business relationships is often a priority for both buyers and sellers. The SPA should include robust confidentiality terms to prevent sensitive details from being disclosed. Restrictive covenants may be imposed on the seller to prevent them from competing with or soliciting customers from the business for a set period after completion.
Dispute resolution clauses are also essential. They set out how any disagreements will be handled, whether through negotiation, mediation, or formal proceedings. Having these provisions in place can save time and money if issues arise down the line.
Pro tip: The right restrictive covenants and dispute resolution provisions can give you peace of mind long after the deal is done. We can draft these to suit your situation and objectives.
