Spanning over four decades as lawyer, Judge, Justice, and JAMS mediator/arbitrator, Hon. Sheila Prell Sonenshine has embraced the challenges of emotionally charged disputes and brought them to successful resolution.
As an attorney she played an instrumental role in the development of a computerized estate planning program for a prominent Wall Street brokerage firm while working effectively with its high net worth clients. Her estate planning practice also included consulting with families of Western Regional Center patients, the drafting of pre-marital agreements, and providing legal advice on conservatorships as well as estate, trust, and probate litigation.
Justice Sonenshine wrote scores of opinions in matters involving wills, trusts, and intestacy in her nearly twenty years on the bench. She also resolved hundreds of cases at settlement conferences, including 85% of those that she heard under the appellate settlement conference program she inaugurated.
Justice Sonenshine founded and served as Managing Director of an international investment banking firm (M&A) focused on privately held mid market businesses. This experience makes her particularly adept in resolving closely held family business disputes.
As a mediator she is sensitive to the personal nuances involved in estate, probate, and trust litigation. She is known for patiently working to bring the parties together and for her common sense approach to resolving disputes.
As an arbitrator, her command of the process, demonstrated fairness, and knowledge of the law and rules result in appropriate, timely, and well-reasoned awards.
