Barry Nussbaum

Barry Nussbaum is the founder and senior lawyer at Nussbaum Law Professional Corporation, a family and divorce law firm with six locations across Ontario. He is a Certified Specialist in Family Law by the Law Society of Ontario, a designation awarded to a limited number of lawyers who have demonstrated extensive experience, knowledge, and proficiency in family law. Called to the Ontario Bar in 2005 and the New York Bar in 2007, Barry holds a Juris Doctor from Osgoode Hall Law School and an MBA from the Schulich School of Business, both from York University. Before practicing law, he worked in international tax consulting for Canadian multinationals, a background that directly informs his approach to the financial complexity of high-asset divorce and property division. With over 20 years of experience dedicated almost exclusively to family and divorce law, Barry leads a growing legal team and provides strategic direction across a broad range of complex matters, including high-conflict parenting disputes, child relocation and Hague Convention cases, support and income determination issues, complex property division, domestic contracts, and sensitive Children’s Aid Society proceedings. Barry’s practice is defined by his ability to manage complex and emotionally charged cases with clarity, strategy, and focus. He represents clients at every stage of the process, from initial consultation through negotiation, mediation, litigation, and trial, and is regularly before both the Ontario Court of Justice and the Superior Court of Justice. He has acted in significant cases involving international child abduction, serious allegations of family violence, high-income support disputes, and intricate financial and property issues. While a skilled courtroom advocate, Barry is equally recognized for his practical approach to resolving disputes efficiently, with a focus on narrowing issues and achieving meaningful, cost-effective outcomes.
