Buying an existing business can be faster than building one from the beginning. The licences, employees, contracts, customers and operating history may already be in place. That convenience is also the source of the principal legal risk: a buyer may acquire not only the business it wants, but also liabilities and restrictions created before it arrived.

The first question is what exactly is being purchased. In a share acquisition, the buyer acquires an interest in the company itself. The company ordinarily continues to own its assets, owe its liabilities and remain party to its contracts. In an asset transaction, the buyer instead acquires identified assets or business components, subject to the transfer requirements that apply to each of them. The legal due diligence process should therefore be designed around the structure of the proposed deal. Reviewing a share purchase as though it were simply a list of assets can miss the liabilities that remain inside the company.

Corporate ownership and authority come first. The buyer should verify the legal existence of the target, its licence, ownership records, constitutional documents, managers and authorised signatories. Any restrictions on transferring the relevant interest should be identified early. The UAE Commercial Companies Law and the relevant licensing regime may affect how ownership can be transferred and which approvals or corporate steps are required. If the seller cannot legally deliver the interest being sold, commercial negotiations about price become secondary.

The review should then examine what gives the business its value. Key customer and supplier contracts may contain change-of-control provisions, termination rights, exclusivity obligations or restrictions on assignment. A valuable lease may not automatically remain available after a transaction. Intellectual property may be used by the business without being properly owned by it. Important equipment may be leased, financed or subject to security. A buyer should distinguish between assets the company actually owns and assets it merely relies on.

Employees and management arrangements can also materially affect the transaction. The buyer should understand key employment terms, accrued liabilities, incentive arrangements, pending disputes and the dependency of the business on particular individuals. If the commercial rationale for the acquisition depends on founders remaining for a transition period, that expectation should be converted into binding transaction documentation rather than left as an informal understanding.

Disputes, regulatory history and compliance should be considered with the same seriousness as financial information. Existing claims, threatened proceedings, unpaid obligations, regulatory notices or compliance gaps can alter the value of the target even if they have not yet resulted in a judgment or penalty. Legal due diligence is not limited to finding current liabilities; it should identify facts that could reasonably develop into liabilities after completion.

The buyer also needs to understand the company’s financial and tax position, although those areas will usually require accountants and tax specialists alongside legal counsel. The legal team should coordinate with those advisers because a financial issue may have contractual consequences and a legal issue may affect valuation. Material debt, guarantees, security, related-party balances and unusual payment arrangements often require both legal and financial analysis.

Due diligence findings are useful only if they influence the deal. A serious issue may justify walking away, but many findings are instead addressed through the transaction structure. The buyer may require a problem to be corrected before completion, reduce or defer part of the price, retain money, obtain a specific indemnity, require warranties, or make completion conditional on an approval or document being obtained. The purpose of due diligence is therefore not to produce a long report. It is to give the buyer information that changes the contract or the decision.

The sale agreement should then allocate risks that cannot be eliminated before closing. Representations, warranties, indemnities, disclosure processes, liability limits and claim procedures all determine who bears the consequences if the information provided about the target proves incomplete or inaccurate. These provisions should be linked to the findings from due diligence; generic warranties cannot substitute for a known risk that requires a specific solution.

Closing mechanics deserve equal attention. The buyer should know which documents will be signed, which approvals are required, when funds are released, how ownership is transferred, and what evidence confirms that completion has occurred. Where several steps must happen together, the transaction documents should prevent the buyer from paying before the legal conditions for transfer have been satisfied.

Legal due diligence does not make a business successful and it cannot uncover information that is deliberately concealed and unavailable through reasonable review. Its purpose is more practical: to test whether the legal reality matches the business being sold, identify the risks that can be discovered, and ensure that those risks are reflected in the buyer’s decision and documents. A buyer should know what it is acquiring before the price becomes irreversible.
