London is the deepest private client legal market in the world. The specialist firms, including Farrer and Co, Withers, Payne Hicks Beach, Boodle Hatfield, Forsters, Charles Russell Speechlys, Mishcon de Reya, Harbottle and Lewis and Taylor Wessing, maintain dedicated private client departments of a size that has no equivalent elsewhere. Chambers and Legal 500 rank them annually; most of the firms listed here appear in the top bands.
The work falls into recognisable categories: UK and international tax and estate planning, trust structuring and trustee advice, super-prime property acquisition, family law including pre-nuptial agreements, reputation and privacy, and increasingly, immigration under the UK's post-2025 regime for wealthy new arrivals.
The abolition of the remittance basis in April 2025 and its replacement with a four-year foreign income and gains regime has changed the advice for internationally mobile clients. Firms with strong cross-border tax capability have become more important, not less.
