Selling Part of Your Business: Asset vs Share Deal Compared

Selling part of your business can be a smart way to raise capital, sharpen your focus, or bring in new expertise. Maybe you’re ready to streamline and concentrate on your most profitable ventures, or perhaps you’ve been approached by an investor eager to buy into your growth. Whatever your motivation, navigating a business sale – whether you “i-sale” assets or shares – is a significant legal and strategic move. But how do you actually sell part of your business (not all of it)? And what’s the difference between an asset sale and a share sale? More importantly, which approach will work best for your business and your goals? If you’re unsure where to start – don’t stress! In this guide, we’ll break down what each method involves, the pros and cons of each, and the key steps (and pitfalls) to watch for. Keep reading to get clear, practical advice before you “sale my business” or answer the question “can I sale just one division?”.

When Might You Sell Part of Your Business?

Let’s start with why a business owner might look to sell off part of their company rather than the whole thing. Here are some of the most common scenarios we see:

• Streamlining focus: Maybe you want to concentrate on your core offering and divest an underperforming or non-core unit.
• Raising capital: You might be looking for a cash injection to fund growth, and selling a division or shares can provide the capital you need.
• Attracting new expertise: Bringing in a strategic investor or partner to help take your business to the next level.
• Managing succession: If you’re preparing for eventual retirement or want to transition ownership gradually.
• Responding to market or personal changes: Sometimes market shifts, changes in your own goals, or financial pressures make it sensible to scale back.

No matter your reasons, a partial sale should always line up with your broader business strategy. The right choice can deliver not just short-term capital, but set you up for future success.

How Can You Sell Part of Your UK Business?

There are two main ways to sell part of a UK business:

1. Asset Sale – You sell specific business assets (like equipment, intellectual property, a customer list, or an entire division).
2. Share Sale – You sell shares in your company to a buyer, effectively transferring a portion of company ownership.

Both routes can be used for a partial or “i-sale” of your business. But which is best for you?

Asset Sale vs Share Sale: What’s the Difference?

It’s easy to confuse the two, but they work very differently – with important implications for control, risk, and tax.

Asset Sale (Selling Parts or Units)

In an asset sale, you are selling specific things owned by the company. This could be equipment, real estate, intellectual property, or even an entire business unit or brand operated by the company. The buyer gets only those assets and, usually, only takes on related liabilities (if any) that are expressly agreed upon.

Share Sale (Selling Company Ownership)

In a share sale, you sell shares in the company itself. That means the buyer acquires a percentage of your business – taking on a stake in all the company’s current and future assets and liabilities (unless excluded by agreement).

Asset Sale vs Share Sale: Pros, Cons & Key Differences

Benefits of an Asset Sale	Benefits of a Share Sale
Streamlines costs by offloading a specific part of the business (without selling everything)	Allows you to bring in a new shareholder without selling or transferring specific assets
Potentially secure a higher price for valuable, standalone assets	No dilution of company assets – you keep the business intact but change the ownership mix
Avoid unwanted liabilities (you can negotiate exactly which assets/liabilities are included in the sale)	May attract investors who want a say in the whole business rather than just buying selected assets
Buyer “cherry-picks” what they want; you keep strategic or profitable units	Simplifies contracts with suppliers and customers (most agreements stay with the company)

Drawbacks to Consider

• Asset Sale:
  • May trigger the need to transfer contracts, licences, or permits (which can be time-consuming or need third-party consent)
  • Some assets, like key supply agreements, may not be easily assignable
  • Tax implications may be significant if asset values have changed or there is capital gains liability
• Share Sale:
  • Buyer inherits all company obligations and known/unknown liabilities unless specifically excluded
  • May result in you giving up strategic control or a say in business direction
  • Can impact employment arrangements, company culture, or decision-making

When Is an Asset Sale Better?

You’ll probably lean towards an asset sale if:

• You want maximum flexibility to keep valuable operations/assets and just sell a segment (e.g. “i-sale” my restaurant brand, but keep my catering business)
• The buyer only wants certain assets – not to take on all your existing contracts or potential risks/liabilities
• You want a clean break from a non-core or underperforming part of the business
• Regulatory, tax, or licensing reasons make selling assets individually easier

When Is a Share Sale Better?

On the other hand, a share sale might be smarter if:

• The buyer wants a stake in the entire business (including goodwill, brand, and ongoing contracts with suppliers and clients)
• You want to bring on an investor with voting rights or an appetite for company growth
• It’s easier to transfer company shares than to assign dozens of customer contracts or licenses individually
• The legal structure of your business (e.g. a Ltd company) enables share sales

A share sale can sometimes be less disruptive to trading: contracts, staff, and leases remain with the company, minimising operational changes. If you’re unfamiliar with share sales, our comprehensive article on share sale vs asset sale gives even more detail and practical examples.

What Legal Documents Will I Need?

No matter which type of partial business sale you choose, having the right legal documents is absolutely critical. The exact documents will depend on your chosen sale method, but often include:

• Asset Sale Agreement – Outlining exactly what is being sold, what stays, the sale price, transfer procedures, and any warranties or liabilities being assumed. (See our guide to Asset Sale Agreements for more details.)
• Share Sale Agreement – Setting out the number of shares being transferred, price, rights of both parties, and requirements for completion. It often covers warranties, indemnities, and other protections. (Read more on Subscription and Shareholders Agreements.)
• Ancillary Documents – Depending on how the sale is structured, you may also need resignation letters (for outgoing directors), new service agreements, revised Shareholders Agreements, or transfer forms.

It’s essential to have these drafted or reviewed professionally, as off-the-shelf templates may not protect you properly – especially for partial sales where clarity on exactly what’s being sold (and what isn’t) is vital.

What Are the Key Strategic Considerations?

1. Business Strategy & Future Direction

The “right” approach to a partial sale depends on your bigger picture strategy. Ask yourself:

• Is the part of the business I’m selling profitable, or do I want to offload something underperforming?
• Will the sale help (or hinder) my company’s long-term prospects and growth?
• Would a new shareholder’s involvement support my future aims, or cause friction?

Remember: sometimes, holding onto certain assets is more valuable than cashing out, especially if they’re core to your business or offer future potential.

2. Tax Implications

Tax is a big consideration – and it’s different for asset and share sales. You might face capital gains tax on the sale of assets, or stamp duty on certain asset transfers. With share sales, buyers inherit company tax positions, which can be an issue if there’s unused tax relief or losses in the business. Getting advice from your accountant is crucial before you proceed, as even a well-priced sale can end up less lucrative after taxes if not structured correctly.

3. Contractual Restrictions and Consents

Review all key contracts (customer, supplier, landlord, franchise, etc.) before you commit. Some contracts might require the other party’s consent before you transfer assets or shares. Similarly, specific regulatory approvals may be necessary, especially in sectors like healthcare, finance, or education. Our piece on changing company ownership elaborates on what to check before making any moves.

Are There Any Legal Risks to Watch For?

Absolutely – and the risks can be very different for each method.

• For asset sales, unclear documentation over which assets (and liabilities) are included/excluded can lead to disputes later.
• For share sales, buyers may discover “hidden” liabilities post-completion, so disclosure and due diligence are essential.
• If you don’t update underlying legal agreements (like leases or licences), the sale might not be effective or could breach third party terms.
• Failing to comply with laws like data protection (see our GDPR overview) during a business handover can lead to fines or reputational damage.

To minimise risk, get a lawyer to review all agreements and advise on the transfer process. Our Business Sale Agreement service can help ensure you’re protected from day one.

Step-By-Step Guide: Selling Part of Your Business

1. Define What You’re Selling – and Why Clarify which assets, divisions, or shares you want to sell, and be clear about your goals (fundraising, exit, strategic investment, etc). 2. Prepare for Sale and Get a Valuation Organise financials, tidy up contracts, and get a professional valuation so you know your asking price and negotiation position. 3. Choose Your Sale Structure Decide between an asset sale and a share sale, with input from your financial, tax, and legal advisors. 4. Negotiate Heads of Terms Outline the main sale points and intentions early (often called “heads of terms” or a Heads of Agreement) to avoid confusion or wasted time later on. 5. Carry Out Due Diligence Both sides investigate the business’s legal, financial, and operational status – be transparent and respond promptly to any information requests. 6. Draft and Negotiate Legal Agreements Instruct lawyers to draft or review Sale Agreements, Disclosure Letters, and any associated documents. 7. Get Necessary Consents and Approvals Check all third-party permissions are sorted before completion date. This includes landlords, franchisors, or regulatory bodies if applicable. 8. Complete the Sale and Transfer Once all paperwork (and money) is exchanged, formally transfer the assets or shares, update your records, and notify Companies House if needed.

Do I Need a Lawyer to Sell Part of My Business?

We strongly recommend you do. The process of structuring and finalising a partial business sale is rarely as simple as it first appears – and mistakes can be costly. A commercial lawyer can help you to:

• Choose the optimal sale structure for your goals and minimise tax risk
• Draft and review watertight agreements tailored to your sale
• Spot hidden liabilities or regulatory issues before they become a problem
• Guide you through disclosures, due diligence, and getting all consents in place

If you’ve been approached with an “i-sell” or “i-sale” opportunity, investing in sound legal advice will save you stress, money, and time in the long run.

Key Takeaways

• Selling part of your business can help you raise capital, streamline operations, or prepare for growth – but it’s important to choose the right method.
• Asset sales let you sell specific units, assets or divisions, but may require intricate transfers of contracts and liabilities.
• Share sales transfer ownership in the company itself and are better suited for bringing in partners or investors who want a stake in the complete business.
• Both methods have important tax, legal, and strategic implications – professional advice is essential.
• Plan thoroughly, clarify which assets/shares are involved, and use tailored legal documents to protect your interests from day one.
• Always check all key contracts, regulatory requirements, and secure necessary consents before completing any transaction.
