About Alison

Alison leads the contentious trust and estate team, representing a range of clients including private individuals, trustees, executors and beneficiaries.  

Alison has significant and wide-ranging experience advising on succession, inheritance and trust issues, often involving international issues and including advice on a variety of issues such as the validity and construction of wills and trust deeds, the removal of fiduciaries, breach of trust claims, claims under the Inheritance (Provision for Family and Dependants) Act 1975 and succession disputes. 

Alison works closely with colleagues in the private client, family and corporate teams when advising on issues that arise that may affect an individual or a family’s long term personal and business interests. This may involve the impact of a pre-nuptial agreement, stress testing trust structures or advising on family wealth structuring so as to avoid a dispute.

She is ranked in Private Client Global Elite and regularly acts in contentious administrations via the Russell- Cooke Trust Company where the trust company is appointed as independent administrator in circumstances involving beneficiary litigation or family disharmony.

With experience in mediation as well as litigation, Alison is known to try and resolve disputes as quickly and cost efficiently wherever possible, but is also a tenacious litigator where she needs to be.

Alison Regan is one of the leading lights for contentious trusts and estates work in London, a recognised leader in our field.
