Sinclair Gibson LLP

Sinclair Gibson is a specialist law firm based in Lincoln’s Inn Fields, London, established in 2019. The firm focuses on private client, litigation, and family law, serving the needs of private clients and their advisers. Its practice model emphasises bespoke, partner-led advice, with practitioners often working across traditional departmental boundaries to provide tailored solutions that span multiple practice areas.

The firm’s private client practice is led by Keith Bruce-Smith, who has more than 30 years of experience and is an author of key works on trusts and wills. He, alongside Lucy Gibson, recognised for her international trust and estate law expertise, advises UK and international individuals and trustees on a wide range of matters.

The litigation practice, headed by Henry Hickman, represents private individuals, charities, and trust companies in trust litigation, succession and probate disputes, and inheritance claims. The team also undertakes commercial litigation in the High Court and in offshore jurisdictions.

The family law department is led by Kathryn Peat and James Copson, both highly regarded practitioners. The team advises on all aspects of family law, with particular strength in high net worth financial remedy claims, nuptial agreements, and domestic and international private children matters. The department also handles disputes involving unmarried couples and the preparation of cohabitation agreements. A significant portion of the work involves international clients, with expertise in offshore trusts, overseas assets, and cross-border relocation of children, supported by the firm’s private client specialists
