About O'Donohue & O'Donohue

O'Donohue & O'Donohue is an established estates, trusts and wealth management law practice in Toronto, founded in 1951. The firm advises individuals, families and their businesses on estate planning, estate administration and estate litigation, along with related tax, corporate and real estate matters. It also handles business succession planning and family law. The firm keeps a network of domestic and foreign professional colleagues it partners with on a case by case basis, so clients working across more than one jurisdiction can draw on a wider range of skills.

The firm's principal, Stephen O'Donohue, is certified by the Law Society of Ontario as a Specialist in Estates and Trusts Law and was called to the Ontario and British Columbia bars in 1988 and 1991. Stephen's education includes a science degree, an MBA in finance and a law degree, and the practice covers estate planning, estate administration and estate litigation, including large and complex estates. The team also includes associate Lauren O'Donohue, who joined in 2023 after articling at Gardiner Roberts LLP, and two counsel lawyers, Jean M. DeMarco and Gregory R. Mallough, who bring civil and estate litigation, family law, corporate and real estate experience to the firm.
