Due diligence - buyers and sellers

Anyone who is thinking of acquiring a business or a company, purchasing shares or assets needs to undertake an audit of the affairs and financial health of the target in question.

This investigative process is referred to as due diligence and it will identify any areas of risk. Potential investors are able to appraise the potential purchase and review important factors such as its contracts, expenses and any claims. It is about getting a full picture of how the target is run, its financial pressures and the state of the accounts.

The due diligence process usually starts following a deal being agreed. Initially, the potential buyer sends enquiries to the seller, which require a response. The enquiries can go backwards and forwards a number of times with additional information requested. During this phase, lawyers and accountants will get involved to support and advise their clients.

It is the opportunity to get any issues out in the open so the buyer is fully aware of the current status and any liabilities. It is vital to be honest in response to the enquiries as, ultimately, the information provided will create the warranties and indemnities – in other words, a guarantee – that the seller has disclosed everything which may affect the buyer once a transaction is completed.

What the buyer needs to do - due diligence

The buyer needs to research the target and find answers to important questions such as why is the entity for sale and is it still profitable? They need to identify potential issues such as employee claims, financial matters or undisclosed assets.

Often, buyers underestimate the importance and demands of this part of the due diligence process. As a buyer you need robust evidence to judge the integrity of the intended purchase.

What the seller needs to do - due diligence

During due diligence the seller will need to consult a professional to assist in responding to the enquiries made by the buyer. Clear guidance is required on making full and frank disclosures about specific issues.

The seller can face an overwhelming stream of enquiries and has to deal with them fully and accurately as the responses are relied upon in the agreement as a whole.

The enquiries form the basis of the disclosure letter and so having professional advice will help in the negotiation process and protect the interests of the seller.

Being honest at this stage is vital to avoid potential claims by the buyer at a later date.

Specialist due diligence solicitors for transactions of every size

When the stakes are high, you need due diligence solicitors who combine commercial judgement with meticulous attention to detail. Our due diligence lawyers support buyers, sellers, investors and management teams on share and asset deals, private equity transactions, mergers and strategic disposals. We scope the issues that matter, interrogate the data room efficiently and deliver pragmatic, plain‑English advice that protects value and minimises risk.

Our buy‑side and sell‑side approach

On the buy‑side, we focus on what can derail price, delay completion or affect integration. We prioritise contract assignability, change‑of‑control risks, key customer dependencies, IP ownership and encumbrances, title to assets, regulatory permissions, financial covenants, litigation exposure and employee liabilities. You receive a concise red‑flag report with a clear risk rating, the practical steps to mitigate each issue and how the findings should feed into price adjustment, conditions precedent, warranties, indemnities and covenant packages.

On the sell‑side, we prepare you early with vendor due diligence to surface and resolve issues before marketing. We help curate a clean, well‑structured data room, draft robust disclosures and align your disclosure letter with the sale documentation, reducing the scope for post‑completion claims. The result is a smoother process, stronger buyer confidence and better deal certainty.

Share purchase v asset purchase due diligence

On a share purchase, the buyer acquires the company with all its liabilities, so the emphasis falls on corporate structure, historical compliance, tax exposures, financing arrangements, pensions, disputes and contingent liabilities. On an asset purchase, title to specific assets, contract novations or assignments, transfer of licences and permits, property transfer formalities and TUPE are central. We tailor our enquiries and reporting to the structure you choose so you are not paying for work you do not need.

What our due diligence lawyers cover

Our scope is tailored to the deal, sector and timetable, but typically spans corporate governance and share capital, commercial contracts and supply chains, data protection and information security, intellectual property, real estate and environmental matters, employment and pensions, regulatory licences and consents, disputes and complaints history, insurance and risk, financing and security, and sector‑specific compliance. Where necessary we bring in specialist colleagues in tax, competition, property, employment, regulatory and dispute resolution to give a joined‑up view.

Sectors we understand

We regularly act on transactions in technology and software, healthcare and care services, manufacturing and engineering, logistics and transport, professional and financial services, retail and e‑commerce, hospitality and leisure, and construction and property services. Sector familiarity allows us to ask the right questions faster and to signpost the commercial consequences of findings with confidence.

How we manage the process

We begin with a scoping call to agree materiality thresholds, key risks, timelines and reporting format. We then run focused enquiries through a secure data room, escalate information gaps early and maintain a live issues list so there are no surprises at the eleventh hour. Findings are delivered in an executive summary with a visual risk heat map and an annex of supporting detail. We coordinate closely with your corporate lead on the sale and purchase agreement so warranties, indemnities, disclosures and conditions reflect the realities uncovered.

Timeframes you can rely on

Speed matters. For straightforward SME transactions, headline findings can often be delivered within five to ten working days of receiving a complete data room. Complex, multi‑site or highly regulated targets will take longer. We resource the matter appropriately from day one and keep you informed of progress against milestones throughout.

Pricing that is transparent

Where the scope is defined, we can offer fixed or capped fees with clear assumptions, staged billing and no hidden extras. For evolving projects, we agree sensible materiality thresholds and reporting formats to control cost while ensuring that critical issues receive the attention they deserve.

Risk mitigation and deal negotiation

Due diligence is only valuable if it changes outcomes. We translate findings into action by shaping price chips and earn‑out mechanisms, negotiating targeted indemnities, ring‑fencing known liabilities, structuring holdbacks and retention arrangements, tightening pre‑completion undertakings and ensuring appropriate consents are obtained before completion. Our goal is to protect value without creating unnecessary friction.

Regulatory and cross‑border considerations

For regulated targets, we assess permissions, supervisory history and change‑in‑control rules. We address data protection compliance, international data transfers and information security hygiene.

Frequently asked questions

What is legal due diligence?

Legal due diligence is a structured review of a target’s legal and commercial position to identify risks and value drivers. It informs pricing, contractual protections and the go or no‑go decision, and it helps avoid unpleasant surprises after completion.

How long does due diligence take?

The timeframe depends on the size of the business, the completeness of the data room and regulatory complexity. With good cooperation, initial red‑flags can often be issued within one to two weeks, with deeper dives following as required.

What documents are usually required?

Typical materials include constitutional documents, statutory registers, key customer and supplier contracts, IP registers and licences, employee contracts and policies, property documents, insurance schedules, litigation records, financial agreements and regulatory correspondence. We provide a tailored checklist at the outset to streamline collation.

Can you act for both buyer and seller?

No. To maintain independence and avoid conflicts of interest, one team cannot act for both sides on the same transaction. We can, however, recommend trusted advisers for the other party if asked.

What is vendor due diligence and do I need it?

Vendor due diligence is a seller‑commissioned review to identify and fix issues before going to market and to provide credible information to potential buyers. It can reduce execution risk, shorten timetables and support stronger valuations, particularly where multiple bidders are expected.

How do you protect confidentiality?

We agree non‑disclosure agreements, use secure data rooms with granular permissions and limit document circulation to essential personnel. Sensitive information can be staged or anonymised until later in the process.

What happens if due diligence uncovers issues?

Findings rarely mean a deal must fail. We assess materiality, quantify exposure and propose solutions such as price adjustments, indemnities, insurance, enhanced disclosures, remediation before completion or adjusted transaction structures.
