Gabrielle Vidal is co-chair of Loeb & Loeb’s Trust and Estate Litigation Practice. She concentrates on high-net-worth trust, probate, conservatorship, and guardianship litigation, and is known for her success at trial in high profile private wealth disputes. Most recently, she served as lead trial counsel to Sumner Redstone, controlling shareholder of Viacom Inc. and CBS Corp., securing complete dismissal of the matter after the first day of trial.

Cited by The Wall Street Journal as “an expert who litigates disputes over wills and high-net-worth trusts,” Gabriellel’s practice includes disputes regarding the obligations of fiduciaries; interpretation of testamentary instruments; and trust and probate issues arising in the context of family law proceedings.

Gabrielle represents 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 practitioners.

Gabrielle was appointed to the Judicial Council of California’s Probate and Mental Health Advisory Committee. She is a past member of the Los Angeles County Bar Association Trust and Estate Executive Committee.
