About Montagnese and Sherr LLP

Montagnese and Sherr LLP is a small law firm based in Toronto, operating from Suite 703 on Islington Avenue. Partners Katherine Montagnese and David Sherr serve clients across the Greater Toronto Area, and the firm concentrates on three areas: family law, wills and estate planning, and real estate law.

Katherine Montagnese practices across all three areas, handling separation agreements and parenting arrangements alongside residential closings and personalized estate plans. Montagnese has appeared before the Superior Court of Justice, the Ontario Court of Justice, and the Ontario Court of Appeal, and also assists clients with mediation and arbitration. David Sherr focuses on family law and has practiced in the field since being called to the bar in 2012, appearing before the Ontario Court of Justice, Superior Court of Justice, Divisional Court, and Court of Appeal, along with private arbitrations. The firm's real estate practice offers flat rate pricing for most residential purchases, sales, and refinances, and its estate planning work extends to specialized tools such as Henson trusts for beneficiaries with disabilities.
