Mergers and acquisitions (M&A) is a broad term covering transactions where businesses combine or change ownership. In practice, most deals involve one business buying another, though true mergers where companies combine as equals also happen.
An acquisition is when one business buys another. This might be a share purchase (buying the company’s shares from its shareholders) or an asset purchase (buying specific assets and parts of the business rather than the company itself).
A merger is when two or more businesses combine to form a single entity. The original companies typically cease to exist separately, with their assets, liabilities, and operations merging into the new combined business.
For SMEs and owner-managed businesses, the most common transactions are:
Whatever the structure, M&A transactions involve significant legal complexity. The documentation needs to protect your interests, allocate risks fairly, and ensure a smooth transfer of ownership.

Whether you’re buying, selling, or advising management, we provide practical legal support throughout the transaction.
Selling a business you’ve built is a significant decision. You want to maximise value, minimise risk, and ensure a smooth handover. We help sellers prepare for sale, manage the process, and negotiate terms that protect them after completion.
We can help you with:
Buying a business is an investment that needs protecting. You need to understand what you’re buying, identify risks, and secure contractual protections. We help buyers conduct due diligence, negotiate fair terms, and complete acquisitions smoothly.
We can help you with:
MBOs and MBIs have their own dynamics. Management teams need to balance their role as employees with their position as buyers, often while working with private equity backers and lenders. We understand these complexities and help management teams navigate them.
We can help you with:
PE-backed transactions bring additional complexity. Investors have their own requirements around governance, reporting, and exit rights. We work with both PE houses and portfolio companies on investments, bolt-on acquisitions, and exits.
We can help you with:
Sometimes businesses need to reorganise before or after a transaction. This might involve demerging parts of a group, transferring assets between companies, or preparing a business for sale by separating the trading operations from property or IP.
We can help you with:
One of the first decisions in any acquisition is whether to buy shares or assets. The choice has significant implications for risk, tax, and practicality.
In a share purchase, the buyer acquires the shares in the target company from its shareholders. The company itself, with all its assets, contracts, employees, and liabilities, stays the same. Only the ownership changes.
Advantages:
Disadvantages:
Best for: Acquiring established businesses where continuity matters, where contracts require consent to assign, or where the target’s corporate history is clean.
In an asset purchase, the buyer acquires specific assets and parts of the business rather than the company itself. The buyer chooses which assets, contracts, and liabilities to take on.
Advantages:
Disadvantages:
Best for: Acquiring specific parts of a business, distressed acquisitions, or situations where the buyer wants to avoid historical liabilities.
Every transaction is different, but most M&A deals follow a similar path. Here’s what to expect:
Before any deal gets underway, there’s groundwork to do. Sellers should get their house in order: reviewing contracts, tidying up corporate records, and identifying any issues that might affect value or saleability. Buyers should clarify their objectives and what they’re looking for in a target.
Getting legal and tax advice early is worthwhile. Structuring decisions made at this stage can have significant implications later. If you’re selling, a pre-sale legal health check can identify and fix problems before a buyer finds them.
Typical timeframe: 2-8 weeks (longer for complex situations)
Once buyer and seller reach agreement in principle on price and key terms, this is typically documented in heads of terms (also called a letter of intent or memorandum of understanding). Heads of terms are usually non-binding on the commercial terms but may include binding provisions on confidentiality, exclusivity, and costs.
Getting heads of terms right is important. They set the framework for negotiating the detailed legal documents. Issues that aren’t addressed at this stage often become contentious later.
Typical timeframe: 1-2 weeks
Due diligence is the buyer’s investigation of the target business. The seller provides information (usually through an online data room), and the buyer’s advisers review it, ask questions, and identify risks.
Due diligence typically covers legal, financial, tax, and commercial matters. The scope depends on the deal size, the buyer’s appetite for risk, and what’s already known about the target. For smaller deals, a focused approach targeting the key value drivers often makes sense.
Under English and Welsh aw, the principle of “caveat emptor” (buyer beware) applies. The buyer bears the risk of problems it didn’t discover. Thorough due diligence protects the buyer and informs negotiations on warranties, indemnities, and price.
Typical timeframe: 3-6 weeks
With due diligence underway or complete, lawyers draft the main transaction documents. For a share purchase, this is a share purchase agreement (SPA). For an asset purchase, it’s a business and asset purchase agreement (BAPA or APA).
These documents set out the mechanics of the transaction, the consideration, representations and warranties, indemnities, limitations on liability, restrictive covenants, and conditions to completion. Negotiating these provisions is where much of the legal work happens.
There will also be ancillary documents: disclosure letters, tax deeds, service agreements for continuing directors, property documents, IP assignments, and whatever else the specific transaction requires.
Typical timeframe: 3-6 weeks
The seller prepares a disclosure letter qualifying the warranties in the sale agreement. The disclosure letter sets out known exceptions to the warranties and typically refers to documents in the data room. If something is properly disclosed, the buyer can’t claim for breach of warranty on that point.
Disclosure is a critical exercise. Incomplete or unclear disclosures can lead to post-completion disputes. Sellers need to take disclosure seriously and ensure it’s comprehensive and fair.
Runs alongside documentation
Once documents are agreed, conditions satisfied, and parties ready, the transaction completes. This involves signing the final documents, transferring shares or assets, paying the consideration, and updating registers and filings.
For straightforward deals, signing and completion happen simultaneously (a “sign and complete” deal). For more complex transactions, there may be a gap between signing and completion while conditions are satisfied (a “split exchange and completion”).
Typical timeframe: 1-2 days for the completion meeting itself
After completion, there’s still work to do. This includes filing changes at Companies House, updating statutory registers, paying stamp duty on share transfers, integrating the acquired business, and dealing with any completion accounts or earn-out arrangements.
If issues arise post-completion, the buyer may have claims under the warranties or indemnities. How these are managed depends on the contractual provisions and the relationship between the parties.
Ongoing
Understanding the key provisions in M&A documentation helps you negotiate more effectively. Here are the terms that matter most:
Warranties are statements of fact about the target business made by the seller (and sometimes by management). They cover matters like the accuracy of accounts, ownership of assets, compliance with laws, employment matters, tax, contracts, and litigation.
If a warranty turns out to be untrue, the buyer can claim damages for breach of contract. The measure of damages is typically the difference between the value of what the buyer got and what it would have been worth if the warranty had been true.
Indemnities provide pound-for-pound protection against specific identified risks. Unlike warranties (where damages may be limited), indemnities typically cover the full loss suffered.
Indemnities are usually sought for known issues identified in due diligence, tax liabilities, or specific risks where the buyer wants full protection. They’re negotiated based on the specific circumstances of the deal.
The disclosure letter qualifies the warranties by setting out known exceptions. It typically has two parts: general disclosures (standard matters like publicly available information) and specific disclosures (particular issues disclosed against particular warranties).
The disclosure process is important. If something isn’t disclosed, the seller may be liable for breach of warranty. If it is disclosed, the buyer can’t claim but should factor the issue into its assessment of value and risk.
Sellers will seek to limit their liability under the warranties and indemnities. Common limitations include:
The purchase price might be paid as a lump sum on completion, but other structures are common:
For many deals, the final price is adjusted based on completion accounts prepared after the transaction closes. This adjusts for movements in working capital, cash, or debt between the accounts date and completion. The mechanism needs careful drafting to avoid disputes.
Sellers are typically restricted from competing with the business they’ve sold, soliciting its customers or employees, or using confidential information. These covenants need to be reasonable in scope and duration to be enforceable.
Due diligence is about understanding what you’re buying and identifying risks. Legal due diligence typically covers:
Confirming the target’s corporate structure, share capital, constitutional documents, and governance arrangements. Checking that the seller has good title to sell.
Reviewing key contracts with customers, suppliers, and partners. Identifying change of control provisions, termination rights, and any consents needed.
Understanding the workforce, employment contracts, policies, and any ongoing issues. Assessing pension arrangements and TUPE implications.
Reviewing property ownership, leases, and any issues affecting the target’s premises. Identifying consents needed from landlords.
Confirming ownership of key IP (trademarks, patents, copyrights, domain names). Checking that IP has been properly assigned to the company.
Identifying ongoing or threatened litigation, regulatory investigations, or disputes.
Checking licences, permits, and regulatory compliance. Identifying any issues with health and safety, environmental, or sector-specific regulation.
Reviewing GDPR compliance, privacy policies, and data processing arrangements.
Identifying tax liabilities, reviewing tax compliance, and understanding the tax implications of the transaction structure. This is typically undertaken by accountants.

The support we had from the team at Darwin Gray meant that we were able to achieve what we needed without complication.
Darwin Gray supported family-run business Flocon in successfully completing a company share buy-back in early 2024. Flocon is a distributor of products servicing the pipeline industry nationwide, based at Treforest Industrial Estate. The transaction saw the two founders and brothers retire, with the future of the company transferring to the safe hands of the remaining shareholders and directors within the family.
We supported an established manufacturing company in the acquisition of another manufacturer as part of their expansion plans. The target business complemented our client’s existing business, and enabled them to expand further into the sector.
We acted for the sellers of a family-run security systems business in the sale of their business to a national acquirer as part of our client’s exit strategy. The transaction was completed within approximately 3 months and we assisted the sellers throughout the extensive due diligence process through to completion.
Mergers and acquisitions (M&A) refers to transactions where businesses combine or change ownership. A merger is when two or more companies combine to form a single entity. An acquisition is when one business buys another, either by purchasing its shares or its assets. In practice, the term “M&A” covers a wide range of transactions including company sales and purchases, management buyouts, private equity investments, and corporate restructurings.
Timescales vary significantly depending on the deal’s size and complexity. A straightforward transaction might complete in 6-10 weeks from heads of terms. More complex deals typically take 3-6 months, and large or complicated transactions can take longer. Key factors affecting timing include the extent of due diligence, how aligned the parties are on terms, whether regulatory approvals are needed, and the availability of all parties to progress the transaction.
It depends on your circumstances. A share purchase is often cleaner and simpler, with contracts and employees transferring automatically, but you inherit all the company’s historical liabilities. An asset purchase lets you cherry-pick what you want and leave unwanted liabilities behind, but it’s more complex and contracts typically need to be novated or assigned. The right choice depends on factors including the target’s liability history, key contracts, tax implications, and operational considerations. We’ll help you work through the options.
Due diligence is the investigation a buyer conducts before completing an acquisition. It involves reviewing information about the target business to verify what’s being sold, identify risks, and assess value. Due diligence typically covers legal, financial, tax, and commercial matters. The findings inform negotiations on price, warranties, indemnities, and deal structure. Under English law, the principle of “buyer beware” means the buyer bears the risk of problems not discovered, making thorough due diligence essential.
Warranties are contractual statements about the target business made by the seller. They cover matters like the accuracy of accounts, ownership of assets, compliance with laws, and the state of contracts and employment. If a warranty turns out to be untrue, the buyer can claim damages. Warranties matter because they allocate risk between buyer and seller and provide the buyer with contractual protection beyond what due diligence reveals.
A disclosure letter qualifies the warranties in the sale agreement by setting out known exceptions. If the seller discloses an issue properly, the buyer can’t claim for breach of warranty on that point (though it should factor the issue into its assessment of value). The disclosure process is important for both parties: sellers need to disclose comprehensively to limit liability, while buyers need to review disclosures carefully to understand what they’re accepting.
If issues arise post-completion, the buyer may have claims under the warranties or indemnities in the sale agreement. The availability and value of these claims depends on what was warranted, what was disclosed, and the contractual limitations on liability. Claims typically need to be brought within a specified time period. Having well-drafted documentation and thorough disclosure reduces the likelihood of disputes.
M&A transactions involve significant legal complexity. Getting the structure wrong can have serious tax consequences. Poor documentation can leave you exposed to liabilities or unable to enforce your rights. Inadequate due diligence can mean buying problems you didn’t know about. While there’s no legal requirement to use a solicitor, professional advice is strongly recommended. The cost of getting it wrong far exceeds the cost of doing it properly.
TUPE (Transfer of Undertakings Protection of Employment Regulations 2006) protects employees when a business transfers to a new owner. It applies to most asset purchases and some share sales where there’s a service provision change. When TUPE applies, employees transfer automatically to the buyer on their existing terms, and dismissals connected with the transfer may be automatically unfair. Both buyer and seller have information and consultation obligations. Understanding TUPE implications is an important part of deal planning.
An earn-out is a payment mechanism where part of the purchase price depends on the business’s future performance. Earn-outs are used when buyer and seller disagree on value, when the seller is staying on to run the business, or when future performance is uncertain. They can bridge valuation gaps and align incentives, but they’re also a common source of post-completion disputes. Clear drafting of earn-out provisions is essential.
Yes. Transactions can fail for many reasons: problems discovered in due diligence, failure to agree terms, loss of financing, regulatory issues, or simply one party changing their mind before contracts become binding. Until exchange of contracts, either party can usually walk away (though they may lose their costs). This is why it’s important not to incur significant expense before there’s reasonable certainty the deal will proceed.
