Legal Due Diligence in Business Acquisitions: The Specific Provisions Buyers Most Commonly Miss — and How to Read a Disclosure Schedule
Legal due diligence is the workstream that most acquisition entrepreneurs are least equipped to engage with directly. They understand the financial analysis. They have formed a commercial view of the business. They have assessed the management team. Then the solicitor produces a legal due diligence report and the buyer either reads it and understands a fraction of it, or — more commonly — accepts the solicitor's summary and moves on.
That passivity is expensive. Legal due diligence is the workstream most likely to surface the specific provisions — in leases, in customer contracts, in employment arrangements, in the company's articles and shareholder agreements — that create genuine post-completion complications. The buyer who understands what their solicitor is looking for, and why specific provisions matter, participates in the legal review rather than receiving its output. That participation produces better outcomes — not because it replaces specialist legal advice, but because an informed buyer asks better questions, gives better instructions, and makes better decisions about which legal risks to accept, price, or seek protection against.
This post covers the specific legal due diligence areas where buyers most commonly fall short, the provisions in standard commercial documents that create the most frequent complications, and how to read and assess a disclosure schedule with the level of scepticism and commercial judgement it deserves.
The Commercial Lease: The Most Consequential Legal Document in Most SME Acquisitions
The commercial lease governing the business's trading premises is consistently the single most important legal document in any SME acquisition — and the one most frequently reviewed too late in the process, or with insufficient attention to the specific provisions that matter. We covered this in the Week 3 deal autopsy, where an assignment clause discovered eleven days from exchange nearly ended a deal that had been running for four months. The pattern is so consistent it warrants a dedicated treatment.
Assignment provisions
The right to assign a commercial lease — to transfer it from the current tenant to a new tenant as part of a business sale — is not automatic. Most commercial leases require the landlord's consent to any assignment, and the landlord has the right to grant or withhold that consent subject to reasonable conditions. In a share purchase, the business itself continues as the same legal entity, so there is technically no assignment — the shares change hands, not the lease. But many leases contain change of control provisions that treat a material change in the ownership of the tenant company as effectively an assignment requiring landlord consent.
Due diligence must identify whether the lease contains a change of control provision, what it triggers, and what the landlord's rights are if consent is required. A landlord who is entitled to withhold consent can effectively block the acquisition — or can use the leverage of that right to extract a rent increase, a premium payment, or other concessions as the price of their agreement. As the Week 3 deal autopsy illustrated, discovering this eleven days before exchange, rather than at the start of the legal process, is an entirely avoidable complication.
The fix: make review of the commercial lease, and specifically of the assignment and change of control provisions, one of the first items in the legal due diligence process. Identify the issue, assess the landlord's likely response, and engage the landlord early enough that the process of obtaining consent — which can take weeks — does not threaten the completion timeline.
Lease term and renewal rights
The remaining term of the commercial lease is an asset — or a liability — that directly affects both the operational security of the business and its valuation. A business operating from premises with fifteen years remaining on its lease is in a fundamentally more secure position than one operating from premises with eighteen months to run and an uncertain renewal position.
Review the remaining term, the break clauses, and the renewal rights. Under the Landlord and Tenant Act 1954, many commercial leases in England and Wales carry statutory renewal rights — the tenant has the right to renew the lease on broadly similar terms at the end of the contractual term, subject to specific grounds of opposition by the landlord. But leases can be contracted out of these statutory rights, in which case the tenant has no right of renewal and must negotiate from scratch or vacate at the end of the term. Identifying whether the lease is inside or outside the Act is a basic but critical legal due diligence step.
Repairing obligations and dilapidations
Commercial leases typically impose repairing obligations on the tenant — an obligation to maintain the premises in a defined state of repair throughout the lease term and to return them at the end of the term in at least the condition specified in the lease. In a business with a long history in its premises, the accumulated dilapidations — the gap between the current condition of the premises and the condition required by the repairing obligation — can represent a significant liability.
Due diligence should include a review of the repairing obligations in the lease and, in cases where the premises are older or where there is evidence of deferred maintenance, a physical survey of the dilapidations position. A dilapidations liability that has been accumulating for years is a balance sheet item that is invisible in the company's accounts but very real in terms of the cash the business will eventually be required to spend.
Customer and Supplier Contracts: The Provisions That Affect Transferability
Change of control clauses
In a share purchase, the legal entity — the company — continues to exist, so most contracts continue automatically without the need for the counterparty's consent. The exception is contracts that contain a change of control clause — a provision that gives the counterparty the right to terminate, suspend, or renegotiate if the ownership of the company changes materially.
Change of control clauses are most common in: significant commercial contracts with large corporate customers; finance agreements with banks and other lenders; licence agreements for software, intellectual property, and proprietary systems; and franchise agreements. Each one needs to be identified, the trigger conditions reviewed, and the likelihood of the counterparty exercising their rights assessed.
A customer with a change of control right is not automatically going to exercise it — they may have no commercial reason to do so and may be entirely happy to continue with the new owner. But identifying the clause in advance gives the buyer the opportunity to proactively manage the relationship before the customer discovers the change of ownership from another source. A customer who learns about the acquisition from a press announcement rather than from a direct conversation with the new owner is more likely to exercise any rights they have than one who has been personally briefed and reassured.
Assignment restrictions in supplier contracts
Supplier contracts often contain restrictions on assignment — provisions that prevent the customer from transferring the contract to a new entity without the supplier's consent. In an asset purchase, where the buyer is creating a new legal entity that takes on the business's assets, these assignment restrictions directly affect the buyer's ability to continue using the supplier on existing terms. Every significant supplier contract needs to be reviewed for assignment restrictions and, where they exist, the supplier's likely response to a request for assignment consent needs to be assessed early in the due diligence process.
Most-favoured-nation and exclusivity provisions
Some customer contracts contain most-favoured-nation clauses — provisions that entitle the customer to the same commercial terms as the supplier's most favourable customer. If the acquired business has such clauses in its customer contracts, the new owner inherits them and must honour them. Introducing different pricing for new customers, or adjusting pricing for existing customers, may trigger MFN claims from customers who have the right to demand equivalent terms.
Exclusivity provisions — which prevent the business from providing services or products to specified competitors of the customer — can significantly constrain the business's commercial freedom under new ownership. Both types of provision need to be specifically identified and their commercial implications assessed as part of the legal due diligence.
Employment Documentation: Beyond the Basic Checklist
Restrictive covenants — what is and is not enforceable
Non-compete clauses, non-solicitation clauses, and garden leave provisions are standard features of employment contracts for senior roles in most UK businesses. Their value as protection for the business depends entirely on whether they are enforceable — and the enforceability of restrictive covenants in English law is notoriously fact-specific.
A non-compete clause that prevents an employee from working in the same industry for twelve months post-employment may be enforceable for a senior director with access to genuinely confidential client lists. The same clause applied to a junior fee earner with no access to strategic information is likely to be struck down by a court as an unreasonable restraint of trade. The legal due diligence should review the restrictive covenant provisions in all key employee contracts and provide an honest assessment of which ones are likely to be enforceable in practice — not just which ones exist on paper.
This assessment matters particularly in professional services businesses, where the departure of senior fee earners carrying client relationships is the most significant retention risk. As the Week 15 deal autopsy illustrated, notice periods and restrictive covenants on paper provide limited protection if the departing employee has had twelve months to restructure client relationships before actually leaving.
TUPE — the obligations that most buyers underestimate
TUPE — the Transfer of Undertakings (Protection of Employment) Regulations 2006 — applies to both business transfers and service provision changes. In an asset purchase, TUPE transfers the employees of the business to the new employer automatically, on their existing terms and conditions, with continuity of employment preserved. The buyer cannot simply choose which employees to take on — all employees who are assigned to the transferred undertaking transfer regardless of the buyer's preference.
The specific TUPE obligations that buyers most frequently underestimate: the information and consultation requirements (which must be completed before the transfer, not after), the obligation to honour all existing employment terms including any informal benefits or arrangements that have been provided consistently enough to acquire contractual status, and the liability for any employment claims that arise from pre-transfer conduct — which in a share purchase transfers with the company but in an asset purchase may also transfer under TUPE's employee liability information provisions.
Legal advice on TUPE in the specific context of the proposed acquisition structure is essential — particularly where the buyer is planning workforce restructuring in the first year of ownership, where the costs and constraints that TUPE imposes on that restructuring can be significant.
Settlement agreements and historical employment disputes
The disclosure schedule should reveal any settlement agreements, compromise agreements, or historical employment tribunal claims. Review each one carefully. A settlement agreement typically contains confidentiality provisions that prevent the former employee from discussing the circumstances of their departure — which is precisely why they were settled rather than litigated. Understanding what the settlement resolved, and whether the underlying circumstances could repeat under new ownership, requires asking specific questions about the background rather than simply accepting the fact of the settlement.
Corporate Documents: The Articles and Any Shareholder Agreements
Existing shareholder rights
In a business with multiple shareholders — even where one individual holds the majority — the articles of association and any shareholders' agreement govern the rights of the minority shareholders. Pre-emption rights, tag-along rights, drag-along rights, and approval rights for specific corporate actions can all affect the acquisition process and the buyer's post-completion freedom to manage the business.
If there is a shareholders' agreement in place, it should be reviewed as a priority. Shareholders' agreements often contain provisions that give minority shareholders rights that are not obvious from the articles alone — including information rights, veto rights over specific decisions, and rights to appoint a director or observer to the board. A buyer who acquires a majority stake without understanding the minority shareholders' rights may find their commercial freedom significantly constrained in ways they did not anticipate.
Company filing history and statutory obligations
A review of the company's filing history at Companies House — the confirmation statements, the annual accounts, the changes in directors and shareholders — provides a historical record that should corroborate the seller's narrative about the business. Discrepancies between the filing history and the narrative deserve investigation. Late-filed accounts or confirmation statements are a governance signal. Frequent changes in director or shareholder appointments may have an explanation — or may indicate a history of commercial relationships that require understanding.
Reading the Disclosure Schedule: The Skill That Separates Informed Buyers
The disclosure schedule — the document that qualifies the warranties in the SPA by setting out all known facts that would otherwise constitute a breach — is one of the most important documents in any acquisition and one of the least carefully read by most buyers.
The purpose of the disclosure schedule is to shift the risk of known problems from the seller to the buyer. If the seller discloses a matter, the buyer cannot bring a warranty claim for loss arising from that matter — because the buyer knew about it before completion and chose to proceed. Reading the disclosure schedule carefully, and assessing whether each disclosed item is properly understood and appropriately priced into the deal, is therefore one of the most commercially important due diligence activities.
The structure of a disclosure schedule
A well-constructed disclosure schedule typically has two parts: general disclosures (broad references to public information that the seller is deemed to have disclosed) and specific disclosures (particular matters that the seller is specifically flagging as qualifications to specific warranties).
General disclosures — references to information available from Companies House, the Land Registry, HMRC, or other public registers — are standard and largely uncontroversial. They are the seller's attempt to be deemed to have disclosed the full content of public records without having to reproduce them. Buyers' solicitors typically resist overly broad general disclosures that would encompass categories of information the buyer has not actually reviewed.
Specific disclosures are where the real content is. Each specific disclosure relates to a specific warranty and explains a specific fact that qualifies it. The buyer's job is to read each specific disclosure and ask: do I understand what is being disclosed? Does my understanding of the disclosed matter match the due diligence findings? Is the disclosed matter appropriately reflected in the price and structure I have agreed? And is there anything about the disclosed matter that suggests other issues the seller has not disclosed?
The questions a disclosure schedule should prompt
For each specific disclosure, work through these questions:
Is the disclosure clear and specific — does it tell you exactly what the issue is, when it arose, and what the current status is? A disclosure that is vague or general may be concealing the full scope of the issue.
Is the disclosure consistent with what due diligence found? If the disclosure reveals something that due diligence did not surface, understand why — was it a gap in the due diligence scope, or was the information not available in the materials reviewed?
Does the disclosed matter have financial implications that are not yet fully quantified? A disclosed regulatory investigation, for example, may have a disclosed cost of legal fees to date — but the ultimate financial outcome of the investigation may be unknown and potentially material.
Does the disclosed matter suggest anything about the culture of the business's management and its approach to compliance and governance? A disclosure of repeated regulatory breaches across different areas tells a different story from a disclosure of a single isolated incident.
Has the seller proposed specific protection — an indemnity, an escrow, a price adjustment — for the disclosed matter, or are they simply disclosing it and leaving the buyer to accept the risk? If the latter, is that risk appropriately reflected in the overall deal terms?
The disclosure you do not see is as important as the one you do
The most important discipline in reading a disclosure schedule is remembering that it can only disclose what the seller knows about or chooses to disclose. It cannot disclose problems the seller is unaware of, and — in the case of dishonest sellers — it may not disclose problems they are aware of but prefer the buyer not to know about.
The warranty and disclosure process is not a substitute for due diligence — it is a complement to it. The due diligence is designed to find the issues before completion. The disclosure schedule documents the issues the seller acknowledges. The warranties provide recourse for issues that were neither found in due diligence nor disclosed by the seller. All three elements work together — and the buyer who treats any one of them as sufficient in isolation is taking a risk they may not have consciously chosen.
