Eleanor Sinclair

Eleanor Sinclair is widely regarded as one of the UK's most trusted private client lawyers, bringing 18 years of dedicated experience across inheritance law, family law, and financial dispute resolution. Based in London and regularly engaged across North America, Europe, and the Middle East, she advises high-net-worth individuals, families, and business owners on some of the most sensitive and complex legal matters they will ever face — from contested wills and estate disputes to divorce proceedings and cross-border succession planning.

Eleanor's inheritance law practice covers the full lifecycle of estate matters. She advises clients on the drafting of robust and tax-efficient wills, the administration of estates through probate, and the establishment of trusts designed to preserve family wealth across generations. Where disputes arise — whether on grounds of undue influence, lack of testamentary capacity, or improper execution — Eleanor is an exceptionally skilled litigator with a strong track record of achieving favourable outcomes for beneficiaries, executors, and administrators alike.

In family law, Eleanor handles the full spectrum of matrimonial and relationship breakdown matters. Her practice covers divorce and separation, financial remedy proceedings, pre- and post-nuptial agreements, cohabitation disputes, and child custody and care arrangements. She is particularly experienced in representing high-net-worth clients whose cases involve complex asset structures including businesses, pensions, offshore accounts, and international real estate portfolios.

Eleanor's financial law expertise adds a distinctive dimension to her private client practice. She advises on the financial implications of relationship breakdown and inheritance — including asset tracing, pension sharing orders, variation of trusts, and the enforcement of overseas financial orders in UK courts. Her ability to bridge the gap between family law and financial law gives clients a strategic advantage in proceedings where money and family intersect.

A member of Resolution and STEP (Society of Trust and Estate Practitioners), Eleanor is committed to resolving matters wherever possible through constructive negotiation and mediation. She understands that family and inheritance disputes carry enormous emotional weight, and she approaches every case with compassion, discretion, and an unwavering focus on her client's long-term interests.

Eleanor is a recognised thought leader in private client law, regularly contributing to leading publications and speaking at national and international conferences on inheritance, family finance, and trust law. Her insights are frequently sought by fellow practitioners, private banks, and family offices navigating the evolving legal landscape of wealth planning and family dispute resolution.

Given the increasingly international nature of her caseload — with matters regularly spanning the United States, Canada, UAE, and across Europe — Eleanor maintains a dedicated US contact line to ensure clients and counterpart counsel in North America can reach her seamlessly. This reflects her commitment to being genuinely accessible across time zones and jurisdictions, wherever her clients need her most.
