Tips for Businesses
Before entering a share sale, review your company’s Articles of Association to identify any transfer restrictions or board approval requirements. Conduct thorough due diligence to understand all assets, liabilities and contractual obligations being transferred. Ensure all documentation, including Stock Transfer Forms and Share Purchase Agreements, is properly completed and signed. Register the transfer promptly in the company’s register of members to make the sale legally effective.
If you are a founder, business owner or investor looking to grow, restructure or exit a business, you may consider selling or acquiring shares in another company. However, understanding what happens to shares during a sale can feel complex, especially if you are unfamiliar with the legal requirements and practical implications. Under UK company law, if you do not properly structure a share sale, you risk invalid transfers, unexpected liabilities or disputes that could derail your transaction. In this article, we explain what happens during a share sale in a UK private company and guide you through the key legal processes and considerations.
What is a Share Sale?
A share sale occurs when shareholders sell their ownership stakes in a company to new buyers, transferring control and ownership through the purchase of shares rather than individual business assets. Think of it like selling a fully furnished house – the buyer does not just get the property, but everything that comes with it, including the furniture, utility connections and even any outstanding bills.
In a share sale, the buyer acquires the entire company entity with all its:
- assets;
- liabilities;
- contracts;
- employees; and
- trading history.
The company continues as the same legal entity, but with new ownership. This differs from an asset sale, where the parties transfer only specific business assets while the seller retains the original company shell.
Legal Requirements for Share Transfers
Stock Transfer Forms and Documentation
UK law requires you to properly document all share transfers using Stock Transfer Forms. The seller must complete and sign this form, including:
- details of the shares they are transferring
- the purchase price; and
- both parties’ information.
The buyer then receives the completed form along with the original share certificates.
Both parties should retain copies of all transfer documentation for their records. You may also need to notify Companies House of significant shareholding changes through Form CS01. Proper documentation is essential – without it, UK law may treat the transfer as invalid.
Board Approval and Articles of Association
Most private companies include restrictions on share transfers within their Articles of Association. Directors typically have discretionary power to approve or refuse share transfers, particularly to maintain control over who becomes a shareholder. The Articles may require the board to pass formal resolutions before transferring shares to new parties.

The Share Sale Process
Due Diligence and Preparation
Before any share sale, buyers typically conduct comprehensive due diligence to understand exactly what they are acquiring. This involves reviewing the:
- company’s financial records;
- legal agreements;
- employee contracts; and
- potential liabilities.
Sellers should prepare a data room containing all relevant company information and documents. Due diligence helps identify any issues that could affect the sale price or structure.
Share Purchase Agreement Negotiation
The Share Purchase Agreement (SPA) forms the heart of any share sale transaction. This document sets out the:
- purchase price;
- completion conditions;
- warranties about the company’s condition; and
- post-completion arrangements.
Negotiations often focus on the scope of warranties provided by sellers and the indemnities protecting buyers from unknown liabilities.
- purchase price adjustments based on completion accounts;
- retention amounts held in escrow; and
- specific indemnities for identified risks.
The SPA also addresses practical matters like employee retention and integration arrangements.
Completion and Registration
Completion involves the formal exchange of signed transfer documents, share certificates, and payment. The company must then register the transfer in its register of members for the sale to become legally effective. Until registration occurs, the buyer does not become a legal shareholder despite having paid for the shares.
Companies have two months to register transfers or provide valid reasons for refusal. Registration involves:
- updating company records;
- issuing new share certificates; and
- notifying relevant authorities of ownership changes.
What Happens to Different Stakeholders
Existing Shareholders
In a full company sale, all existing shareholders typically sell their stakes simultaneously under the same terms. However, in partial sales, remaining shareholders may see their ownership percentages change and could gain new rights or obligations under updated shareholders’ agreements.
Minority shareholders often benefit from tag-along rights, allowing them to sell their shares on the same terms as majority shareholders. Conversely, majority shareholders may have drag-along rights to force minority shareholders to participate in sales to avoid blocking transactions.
Employees and Management
Share sales generally provide more continuity for employees than asset sales. Staff remain employed by the same company under existing contracts, though new ownership may bring changes to management structure, strategy, or working practices. TUPE regulations typically do not apply to share sales since employees are not transferring between different employers.
However, key employees may have share options or incentive schemes that are triggered by ownership changes. Senior management often negotiate retention packages or earn-out arrangements tied to future performance targets.
Creditors and Suppliers
Company debts and supplier relationships typically continue unchanged through share sales. Creditors remain owed money by the same legal entity, and supplier contracts stay in force unless they contain specific change of control clauses. This continuity can be advantageous for maintaining business relationships and operational stability.
However, some contracts may include provisions allowing termination upon change of ownership. Identifying and addressing these clauses during due diligence helps prevent key relationships being lost after completion.
