As co-chair of Loeb & Loeb’s Trust and Estate Litigation Practice, Gabrielle Vidal concentrates on high net worth trust, probate, conservatorship, and guardianship litigation. Widely recognized for her work, Gabrielle was cited by The Wall Street Journal as “an expert who litigates disputes over wills and high net worth trusts” and was one of 20 lawyers identified on The Hollywood Reporter’s 2018 Troubleshooters list.
Known for her success at trial in high profile private wealth disputes, Gabrielle’s practice includes the representation of public figures in highly publicized controversies. Most recently, she served as counsel to Sumner Redstone, controlling shareholder of Viacom Inc. and CBS Corp., first securing complete dismissal of a challenge to his advance healthcare directive and subsequently obtaining an order confirming Mr. Redstone’s capacity and free will to execute his estate plan.
Gabrielle is an accomplished trial attorney, fiercely protective of her clients and committed to unpacking the psychology and interpersonal dynamics at issue in her cases. Clients turn to Gabrielle not only for her ability to navigate the complex legal and financial issues involved in trust and estate litigation, but also for her understanding and appreciation of the sensitive and emotional nature of these cases.
Gabrielle is one of the most poised, articulate and knowledgeable practitioners that I know. Her papers really are a work of art, her ethics are beyond reproach and she's everything you would want in a litigator, either as your counsel or as your adversary. Chambers USA
Maintaining a practice that is nearly unmatched in her peer group, Gabrielle represents clients in disputes regarding the obligations of fiduciaries; interpretation of testamentary instruments; and trust and probate issues arising in the context of family law proceedings.
Gabrielle’s clients include private and corporate fiduciaries, settlors and individual and charitable beneficiaries. In both her pre-litigation advice work and litigated matters, she teams with Loeb & Loeb’s nationally recognized estate planning and tax controversy practices, giving her clients access to the most sophisticated estate and tax planning practitioners.
Gabrielle is a frequent lecturer in her field, a past member appointed to the Judicial Council of California’s Probate and Mental Health Advisory Committee, and a past member of the Los Angeles County Bar Association Trust and Estate Executive Committee.
