Do I Need A Solicitor To Sell My Business?

Yes, you should usually get legal help when you sell your business - especially once a buyer is serious and money, employees, premises or intellectual property are involved.

That doesn't always mean you need a traditional high street solicitor billing by the hour. Many small business sales can be handled through an online legal team or legal consultancy on a fixed-fee basis. The real point is that the sale documents need to match what you're actually selling.

The tricky part is that "selling a business" can mean two very different things: an asset sale or a share sale. Each route has different documents, risks, warranties and handover steps, so it's worth getting the structure right before you sign anything.

Do I Need A Solicitor To Sell My Business?

Yes, in most cases you should get legal support to sell your business because the business sale agreement does much more than record the price.

A properly drafted agreement deals with what is being sold, when payment is made, what happens if something goes wrong, and what promises you're giving to the buyer. If those details are vague, you can end up with disputes after completion - for example, over unpaid invoices, staff liabilities, customer refunds, stock value or whether a social media account was included.

You may be able to keep things lighter if you're selling a very simple sole trader business with no staff, no lease, no major assets and a low sale price. Even then, a short tailored agreement is safer than relying on emails and a bank transfer.

Legal help is especially useful where your sale involves:

  • A limited company, shares or Companies House updates
  • A commercial lease or landlord consent
  • Employees, contractors or TUPE issues
  • Trade marks, copyright, software, domain names or confidential information
  • Deferred payments, earn-outs or seller finance
  • Warranties, indemnities or a detailed disclosure process
  • A buyer asking for a due diligence pack before they commit

A business sale solicitor in the UK, or a commercial legal team experienced in small business sales, can help you choose the right structure and avoid signing heads of terms that accidentally lock you into a bad position.

Is It An Asset Sale Or A Share Sale?

It depends on what the buyer is actually purchasing: selected assets from your business, or the shares in the company that owns the business.

Asset Sale

In an asset sale, the buyer chooses which business assets and liabilities they want to take over. This might include equipment, stock, customer lists, phone numbers, website domains, goodwill, business name rights, intellectual property and key contracts.

If you run the business through a limited company, the company remains with you after completion. The buyer doesn't automatically inherit the whole company history, but some liabilities can still transfer. Employees are the big one, because the Transfer of Undertakings (Protection of Employment) Regulations 2006, usually called TUPE, can apply when a business or part of a business transfers to a new owner.

Asset sales are common for small business sales because they're flexible. The buyer can avoid taking on unwanted parts of the business, and you can carve out assets you want to keep.

Share Sale

In a share sale, the buyer purchases shares in your limited company. The company keeps owning the business, contracts, assets, liabilities, debts and history. From the outside, the business may look the same, but the shareholders change.

Share sales often need more due diligence and stronger warranties because the buyer takes the company as a whole. If there are hidden tax issues, old employee claims, unpaid suppliers or data protection problems, they usually remain inside the company after completion.

For example, Nina owns 100% of a cafe company in Manchester and agrees to sell for £85,000. If the buyer buys assets, they might take the coffee machines, stock, lease, brand and customer database. If the buyer buys Nina's shares, they take over the whole company, including its bank history, supplier contracts, staff records and any old problems sitting inside it.

You usually need a main sale agreement plus supporting transfer documents, and the exact set depends on whether it's an asset sale or share sale.

For an asset sale, the main document is usually an asset sale agreement. For a share sale, it's usually a share purchase agreement. These aren't just formalities. They set out the deal mechanics and allocate risk between you and the buyer.

Your document pack may include:

  • Heads of terms: A short heads of agreement covering price, structure, deposit, exclusivity and key conditions.
  • Asset sale agreement: The contract for transferring specific business assets, goodwill, any goodwill sale terms and agreed liabilities.
  • Share purchase agreement: The contract for selling shares in a company.
  • Disclosure letter: Your formal exceptions to warranties, used to reduce post-sale claims.
  • IP assignment: A document transferring trade marks, copyright, designs, software, domains or brand assets where needed.
  • Lease assignment or licence to assign: Landlord consent and lease transfer documents if premises are included.
  • Employee transfer information: TUPE and employee liability information where staff are moving across.
  • Board minutes and shareholder approvals: Internal company approvals under the Companies Act 2006 and your articles of association.
  • Stock transfer form: For share sales, usually signed by the seller and dealt with for stamp duty if required.
  • Completion checklist: A practical list of what must happen before funds are released and control changes hands.

Templates often miss the details that matter most, such as deferred payment protections, customer contract consent, lease timing and what happens to debts. A lawyer should tailor the document before it's used, even if the deal feels friendly.

What Should An Asset Sale Agreement Include?

An asset sale agreement should clearly say what is being sold, what is excluded, when completion happens and what each side must do before and after completion.

Here is a fill-in outline you can use to understand the moving parts. It's not a finished legal document, and it should be tailored before you sign anything.

  1. Parties: Write the full legal names of the seller, buyer and any company involved.
  2. Sale Structure: State that the deal is an asset sale and list the business being transferred.
  3. Purchase Price: Set out the amount, deposit, timing, adjustments, earn-out terms and any deferred payments.
  4. Assets Included: List equipment, stock, goodwill, IP, websites, domains, records and customer lists.
  5. Assets Excluded: Spell out what you're keeping, such as cash, personal equipment or certain debts.
  6. Liabilities: Say which liabilities the buyer takes on and which remain with you.
  7. Employees: Deal with TUPE, employee liability information and handover obligations.
  8. Contracts: Identify customer, supplier, franchise, software or finance contracts that need consent.
  9. Premises: Cover lease assignment, landlord consent, deposits, rent apportionments and licences.
  10. Warranties: Record the promises you give about the business and assets.
  11. Restraints: Set reasonable limits on whether you can compete, solicit customers or approach staff after completion.
  12. Completion: List the documents, payments, passwords, keys and records exchanged on completion.

Say Nina's cafe buyer pays a 10% deposit, so £8,500 is paid on signing and £76,500 is due on completion. The agreement should say whether the deposit is refundable, what happens if the landlord refuses consent, and whether stock is included or valued separately. If stock is valued at £4,200 on completion day, the contract should say whether that's already included in the £85,000 or added on top.

What Are Warranties, Indemnities And Disclosure?

Warranties are promises about the business, indemnities are specific risk allocations, and disclosure is how you qualify or limit the promises you're making.

Buyers ask for warranties because they can't know everything about your business from a few meetings and spreadsheet exports. In a share sale, warranties are usually broader because the buyer is taking the whole company. In an asset sale, they may be narrower and focus on the assets, contracts, staff and key information being transferred.

Common warranties cover:

  • Who owns the shares or assets
  • Whether the accounts are accurate
  • Whether there are unpaid debts or disputes
  • Whether customer and supplier contracts are valid
  • Whether employees have been paid correctly
  • Whether intellectual property is owned or properly licensed
  • Whether personal data has been handled under UK GDPR and the Data Protection Act 2018
  • Whether the business has the licences and permits it needs

If a warranty is wrong and the buyer suffers loss, they may try to claim against you after completion. That's why disclosure matters. If you tell the buyer about a problem properly in a disclosure letter, you can often stop them later saying they were misled about that issue.

For example, if one key supplier contract needs consent before assignment, don't just hope it goes unnoticed. Disclose it and make consent a condition of completion. That way, the deal has a clear path instead of a surprise argument after the buyer pays.

What Due Diligence Should I Expect From The Buyer?

You should expect the buyer to ask for documents that prove the business is worth what they're paying and that there are no hidden problems.

Due diligence can feel intrusive, but it's a normal part of selling a business. The best approach is to organise the key documents early and only share sensitive information under a confidentiality agreement.

A buyer may ask for:

  • Company records, articles of association and Companies House filings
  • Management accounts, annual accounts and financial reports
  • Customer and supplier contracts
  • Employment contracts, contractor agreements and staff policies
  • Lease documents, rent deposit deeds and landlord correspondence
  • Trade mark registrations, copyright records, domain ownership and software licences
  • Insurance policies and claims history
  • Privacy notices, data processing agreements and ICO registration details where relevant
  • Licences, permits and regulatory approvals
  • Details of debts, finance arrangements, disputes or complaints

If employees are transferring under TUPE, you normally need to give employee liability information to the buyer at least 28 days before the transfer. This covers information such as employee identities, terms, disciplinary or grievance records from the previous two years, claims and collective agreements.

For a share sale, the buyer may also check the company's statutory registers, persons with significant control records and whether any share issues or transfers were properly approved under the Companies Act 2006. If stamp duty applies to the share transfer, it's generally charged at 0.5% of the consideration, and the buyer usually handles that process with HMRC. Get tax advice on tax treatment, VAT and whether any reliefs or special rules apply.

It depends on the size and complexity of the sale, the structure and how much negotiation is needed.

The main cost drivers are usually:

  • Whether it's an asset sale or share sale
  • How many contracts, employees and premises are involved
  • Whether the buyer needs finance or investor approval
  • Whether payment is all upfront or spread over time
  • How heavily the warranties and indemnities are negotiated
  • Whether there are IP, data protection, lease or regulatory issues

A free template might look attractive, but it can leave big gaps if your sale has staff, a lease, deferred payments or valuable IP. A traditional firm may bill by the hour, which can work well for complex deals but can be hard to budget for. An online legal service can often give you a fixed fee up front for a defined scope, which is useful when you want certainty before committing.

Before you agree to legal support, ask what is included. For example, will the quote cover reviewing heads of terms, drafting the sale agreement, reviewing buyer mark-ups, preparing disclosure wording, dealing with completion documents and answering practical questions along the way?

Also keep your accountant close. Legal documents deal with the sale mechanics and risk allocation, while your accountant can advise on tax, VAT, corporation tax, capital gains tax and HMRC reporting. The two pieces need to work together.

Key Takeaways

  • You usually should get legal help when selling a business, especially if there are employees, premises, IP, shares or deferred payments.
  • An asset sale transfers selected business assets, while a share sale transfers ownership of the company itself.
  • The main document will usually be an asset sale agreement or share purchase agreement, supported by disclosure, transfer and completion documents.
  • Warranties and indemnities can create post-sale liability, so they need careful review and proper disclosure.
  • Due diligence is normal, and preparing your records early can make the sale smoother and more credible to the buyer.
  • Legal and accounting advice should work side by side so the deal structure, documents and tax position line up.
