Documents needed to sell a small business

Selling a small business involves a range of legal documents, and the exact package will depend on the type of business (sole trader, partnership, or limited company), what is being sold (shares or assets), and the complexity of the deal. Here is a practical overview of the key documents typically involved in England and Wales.

Preliminary stage documents:

1. Non-disclosure agreement (NDA). This is usually the first document signed, protecting confidential information shared during negotiations.

2. Heads of terms (also called a letter of intent or memorandum of understanding). This sets out the main commercial terms agreed in principle, such as price, structure, and timeline. It is usually not legally binding except for certain clauses like confidentiality and exclusivity.

Due diligence materials:

3. Disclosure letter and disclosure bundle. The seller provides detailed information about the business, its contracts, finances, employees, liabilities, property, intellectual property, litigation, and regulatory compliance. This is the seller's opportunity to disclose anything that qualifies or limits the warranties given in the main agreement.

Core transaction documents:

4. Share purchase agreement (if selling a limited company by way of shares). This is the main contract and typically covers the purchase price, completion mechanics, warranties and indemnities, restrictive covenants, limitations on liability, and conditions precedent.

5. Business asset purchase agreement (if selling the assets of the business rather than shares). This covers which assets are included, allocation of the price among different asset classes, assumption of liabilities, and similar protections to a share sale.

6. Tax deed or tax covenant. In a share sale, this deals with tax liabilities that arose before completion. It is a separate indemnity from the seller to the buyer for pre-completion tax liabilities.

Employee-related documents:

7. TUPE information and consultation documents. If the Transfer of Undertakings (Protection of Employment) Regulations 2006 apply, both parties have obligations to inform and consult affected employees. This is especially relevant in asset sales but can also arise in share sales where there is a reorganisation.

Property documents:

8. Assignment or transfer of lease. If the business occupies premises under a lease, the lease will usually need to be assigned to the buyer with the landlord's consent. A licence to assign from the landlord may be required.

9. If freehold property is included, a transfer deed (TR1) will be needed.

Ancillary documents:

10. Board minutes and shareholder resolutions. In a share sale, both the seller's and buyer's companies will usually need board approval. If pre-emption rights exist in the articles of association, shareholder waivers or resolutions may be needed.

11. Stock transfer forms. In a share sale of a private company, these are the forms used to transfer the shares.

12. Deed of restrictive covenants. The buyer will normally require the seller (and sometimes key individuals) to agree not to compete, solicit customers, or poach employees for a defined period and area.

13. Service agreements or consultancy agreements. If the seller is staying on in any capacity after completion, a new contract will be needed.

14. Intellectual property assignment. If IP is held personally or outside the company, a formal assignment may be needed to transfer it.

15. Notices to customers, suppliers, and counterparties. Many commercial contracts contain change of control provisions or require notice of assignment.

16. Completion accounts or locked box mechanism documentation. These deal with how the final price is calculated, depending on the pricing mechanism agreed.

Post-completion filings and notifications:

17. Companies House filings. In a share sale, confirmation of new directors, resignation of old directors, and updated persons of significant control (PSC) register entries must be filed.

18. HMRC notifications. Both parties may have tax reporting obligations. Stamp duty of 0.5 per cent is payable on the share transfer in a share sale.

Important considerations:

The distinction between a share sale and an asset sale is fundamental. A share sale transfers the entire company including all its liabilities, whereas an asset sale lets the buyer cherry-pick assets and usually leaves historical liabilities with the seller. The tax consequences for both parties differ significantly between the two.

The scope and detail of warranties and the disclosure process are usually the most heavily negotiated parts of the deal. Getting the disclosure letter right is critical for the seller because it limits exposure under the warranties.

If the business holds regulatory licences or authorisations, you will need to check whether these can transfer and what notifications or applications are required.

The timescale, cost, and complexity scale up considerably with the size and nature of the business, so for even a relatively small transaction it is worth having the documents professionally drafted or at least reviewed to avoid costly problems down the line.

If you can tell me more about the structure of the business and whether you are the buyer or seller, I can give more targeted guidance on what to prioritise.
