About Duplain Law

Duplain Law Professional Corporation is a family law firm in the Orleans area of east Ottawa, founded in June 2016. Its founder, Steve Duplain, was called to the Ontario Bar in June 2010, after earning a B.A. with honours in psychology from the University of Ottawa in 2005 and an LL.B. from the same university in 2009. Duplain spent the years leading up to the firm's founding as an associate at Chénier & Notturno, focusing on family law, before opening Duplain Law.

Duplain Law has practiced family law in Ottawa since 2016, and its practice covers custody and access, support, property division, and divorce, along with preventative agreements such as marriage contracts and separation agreements. Duplain has also completed certified training in family mediation and is an active member of Collaborative Divorce Ottawa, so clients can pursue a negotiated settlement instead of a trial. The firm rounds out its work with wills, powers of attorney, and notarial services, and offers all of it in English and French.
