About Us

The Firm

Sinclair Gibson LLP is a leading independent private client law firm based in London. We advise a domestic and international client base including corporate and private clients, institutions, professional bodies and trade associations, charitable trustees and other law firms.

Our clients benefit from high quality and robust advice, rooted in independent and intelligent thinking and our extensive experience. Our partners, who specialise in contentious and non-contentious matters, ensure that our clients, many of whom have worked with us for many years, can rely on Sinclair Gibson throughout their lives and when challenges arise.

Core practice areas include:

Non-contentious private client tax, trust and estate planning to create secure and sensible wealth planning arrangements within a rapidly changing international climate for wealthy private clients, their taxation and their private affairs.

Cross-border concerns, including property and family overseas to business assets and offshore trusts.

Litigation on private client matters typically involving high-value, complex cases usually conducted in the High Court (or equivalent courts in other jurisdictions) with the firm having experience of running cases in appeal courts and the Privy Council. Also disputes involving high-value works of art and other chattels, and revenue disputes.

Domestic and international family law, dealing with all aspects of the creation of and breakdown of relationships. Particular emphasis on nuptial agreements, financial disputes and all their consequences and arrangements for children, including international relocation.
