The Legal Implications of Selling a Business with International Operations.

Which country's law actually governs the sale

A share sale of a UK parent company is typically governed by English law even where the group has overseas subsidiaries, because the buyer is acquiring shares in a UK entity. Complications arise when a buyer wants, or is legally required, to acquire specific overseas subsidiaries directly, or when local law imposes its own transfer requirements, such as notarisation, government approval, or registration with a local companies registry. Sellers should identify early which jurisdictions require separate local completion steps, since these can add process time that is easy to underestimate if only the UK legal team is consulted.

Currency exposure is a related practical issue that often gets overlooked until late in the process. Where overseas subsidiaries trade in a currency other than sterling, a buyer will want to understand how exchange rate movements have affected historic reported profit, and how proceeds will ultimately be converted and repatriated to the seller. This does not usually change the legal structure of the deal, but it affects how financial information should be presented and explained during due diligence, and sellers who address it proactively avoid unnecessary back and forth once negotiations are underway.

How overseas tax exposure affects deal structure

International operations usually mean the group is taxed in more than one country, and a buyer's tax advisers will check whether profits have been correctly allocated between jurisdictions, whether transfer pricing between related entities is properly documented, and whether any withholding tax applies to dividends or royalties moving between the overseas subsidiary and the UK parent. UK tax treatment of the sale itself depends on individual circumstances and current reliefs, which change, so sellers should take specific advice rather than relying on general assumptions about how the proceeds will be taxed.

Dispute resolution clauses in overseas contracts deserve particular attention, since a contract governed by a foreign jurisdiction with an unfamiliar arbitration process can be harder for a buyer's advisers to assess quickly, and this uncertainty is sometimes priced into an offer as additional risk. Reviewing key overseas contracts specifically for governing law and dispute resolution terms, alongside change-of-control provisions, gives sellers a clearer picture of which agreements are likely to need renegotiation or consent before completion can proceed.

Employment and regulatory rules abroad

Employment law varies significantly by country, and some jurisdictions give employees or works councils a statutory right to be consulted before a change of control, or impose automatic transfer protections similar to UK TUPE rules. Regulated sectors such as financial services, healthcare or defence may also require local regulatory notification or approval before ownership changes, and missing this step can delay completion even after commercial terms are agreed. Identifying which overseas jurisdictions carry these requirements should happen during preparation, not after heads of terms have been signed.

Contracts, IP and data that cross borders

Many international businesses hold customer contracts, licences or intellectual property registrations in the name of an overseas entity rather than the UK parent, and a buyer will want confirmation these assets transfer cleanly with the sale. Key supply or distribution contracts sometimes include change-of-control clauses that require counterparty consent, and losing one during a cross-border deal can be more damaging than in a purely domestic sale because the contract may be harder to replace locally. Data protection rules also differ between jurisdictions, and transferring customer or employee data as part of the sale may need to satisfy both UK and local requirements.

What this means for preparing the sale

Owners of internationally operating businesses should treat legal preparation as a distinct workstream from financial preparation, engaging advisers who understand both UK company law and the relevant overseas jurisdictions before the business goes to market. Buyers researched through the EXITS.co.uk Buyer Demand Analysis (343 acquisition requirements recorded between 2023 and 2025) included a significant proportion of overseas acquirers, at 33.1% of the sample, which underlines why cross-border legal clarity matters even when the seller's own operations are the ones based abroad rather than the buyer's. A clean legal structure, documented early, keeps the process on the business sale timeline owners expect rather than adding months once a buyer's lawyers start asking questions.
