New Square Chambers


Described by Chambers & Partners as ‘an exceptional barrister’, Aidan Briggs has established himself as a specialist advocate and advisor for trusts, estates and property disputes. His regular trial experience in the High Court gives him the edge in the courtroom and makes him a favourite for factually complex cases where effective cross-examination may be the difference between winning and losing.

Aidan’s practice covers the full range of private client matters: contested probate and 1975 Act claims, partnership disputes and contentious trusts work (both on- and offshore) as well as proprietary estoppel, commercial landlord and tenant disputes and trusts of land. His cases often involve multiple jurisdictions and issues of domicile.

Aidan is fully versed in the tax implications of private client disputes and regularly advises in relation to Inheritance Tax, Capital Gains Tax and Stamp Duty Land Tax matters, particularly as they affect farmland and farming families.

Aidan is an Associate Editor of Lewin on Trusts (20th Ed.) and a contributor to Williams, Mortimer & Sunnucks on Executors, Administrators and Probate (21st Ed.). His writing has appeared in Trusts & Trustees, the Wills & Trusts Law Reports and the New Law Journal.

Aidan is sought-after as an accredited mediator and as an arbitrator in his main areas of practice.
