Choosing a Corporate Solicitor UK: Full Guide (2026)

Overview

A corporate solicitor is a legal specialist who works on the life events of a company: formation, share issues, shareholder agreements, mergers, acquisitions, disposals, group reorganisations, investment rounds, and occasionally winding up. They are distinct from commercial solicitors (who focus on day-to-day contracts) and litigation solicitors (who handle disputes), although many firms blur the lines.

In a typical transaction, a corporate solicitor drafts or reviews the share purchase agreement, disclosure letter, and ancillary documents, runs or responds to legal due diligence, negotiates warranties and indemnities, and handles completion mechanics. They will also keep an eye on statutory obligations under the Companies Act 2006, including directors' duties, filings at Companies House, and any required shareholder resolutions.

Because the stakes are high and the drafting is technical, using a generalist solicitor for a corporate deal is usually false economy. You want someone who has done the type of transaction you are doing, in a business of roughly your size, and who can tell you in plain English what the risks are.

Key steps

1. Define what you actually need. Before calling anyone, write down the transaction in one paragraph: what you are buying or selling, the rough deal value, the timeline, and any unusual features such as earn-outs, overseas parties, or regulated activity. This lets you compare solicitors on like-for-like terms and stops you being sold services you don't need.
2. Check qualifications and regulation. Every practising solicitor in England and Wales must be on the roll held by the Solicitors Regulation Authority. Use the SRA's public register to confirm the individual is currently authorised and to see their firm's regulatory history. Membership of bodies like the Law Society is a baseline rather than a mark of excellence.
3. Test sector and deal-size experience. Ask directly how many transactions of your type the solicitor personally led in the last two years, not the firm as a whole. A partner with ten mid-market tech acquisitions under their belt is worth more to a software founder than a City heavyweight who usually works on deals ten times the size.
4. Get fees in writing, ideally capped. A good corporate solicitor will give you a written engagement letter with a fee estimate, hourly rates for each team member, and a sensible scope. For defined workstreams, ask for fixed fees or a cap. Watch out for vague wording that allows costs to balloon if the deal gets complicated.
5. Assess communication and chemistry on a call. Have a proper conversation before instructing. You are going to be in close contact with this person under pressure, often at short notice. If they cannot explain a warranty in a way you understand in the first fifteen minutes, that will not improve once the deal is live.
