Law Office of Jeff O'Brien

About Law Office of Jeff O'Brien

Jeff O'Brien Barrister & Solicitor is a small law firm based in downtown Chatham, Ontario, at 213 King Street West. Family law is the firm's main focus, and it also handles corporate and commercial matters, estate litigation, wills and estate planning, real estate, independent legal advice, and commissioner services. Jeff O'Brien was born and raised outside the small fishing village of Erieau, Ontario, and chose to build a law practice back in the home region rather than elsewhere. The firm serves clients across Chatham-Kent, Windsor-Essex, and Sarnia-Lambton. According to the lawyer's Legal Aid Ontario directory listing, O'Brien practices family law and offers services in English and Spanish.

The office is supported by legal clerk Cathy Knights, who is local to the area and previously worked as a social worker before gaining legal support experience at a Kitchener law firm. On family law files, the firm handles family litigation, separation agreements, adoptions, mediation, and matters involving the Children's Aid Society and the Family Responsibility Office. Its real estate work often overlaps with family law, including helping clients work through property division after a separation. The office keeps regular hours Monday to Friday, with additional appointment times available.
