The firm: Sinclair Gibson is a specialist firm, based in Lincoln’s Inn Fields in London, focused on the needs of the private client and private client adviser through its three complementary practice areas of private client, litigation and family law.

Following in the footsteps of Harcus Sinclair, Sinclair Gibson, which was set up in 2019, represents a return to the core work that the founding partners have always enjoyed and valued and continues to move away from the expansionist business model reliant on compartmentalisation, juniors and precedent-led work increasingly prevalent in the market.

The firm’s model places an emphasis on bespoke advice from experienced, partner-led teams with many of the firm’s practitioners having competence and proficiency across the conventional departmental demarcation, allowing teams for individual matters to span two or more practice areas depending on specific needs.

This ensures that clients benefit from high quality and robust advice, rooted in independent and intelligent thinking as well as extensive experience. These expertise, coupled with individual partners’ personable and pragmatic approach, has resulted in long standing relationships with clients who recognise that Sinclair Gibson is committed to delivering excellent and relevant advice in all aspects of private client law.

Types of work undertaken: 

Private client: the private client practice of Sinclair Gibson is led by Keith Bruce-Smith, a partner with over 30 years’ experience.

Litigation: headed by Alison Meek, the firm’s vastly experienced and well-regarded litigation practice acts for private clients specialises in acting for private individuals, charities and trust companies in trust litigation, succession and probate disputes and inheritance claims.  It also undertakes commercial litigation in the High Court (Commercial Court) and offshore.
