What we stand for.

We understand that family law is not a zero-sum game.  We know that nothing is more important to you than your family.  We take an attentive and proactive approach to family matters and litigation, working closely with clients to achieve the best possible results.  We specialize in finding creative, affordable solutions, and we offer a complete range of family legal services and representation in French or English. 

On Family Law

Experience has taught us that taking a collaborative approach to family law matters can produce the most practical and cost-effective solutions in even the most contentious of situations. Collaborative practice offers clients the opportunity to retain a team of dedicated professionals at a fraction of the cost of litigation.  We also offer bilingual family mediation services in a safe and confidential environment.

On Collaborative Practice & Mediation

We realize that being responsible for your family also means planning ahead.  We work with our clients to prepare affordable, clear and reliable wills and powers of attorney that will bring them peace of mind and security for their families and loved ones.  We can also assist in preparing and notarizing other important documents.  We provide all our services in French and English.

"Steve guided my daughters and I through a very challenging time in our lives.  His expertise, professionalism, empathy and genuine interest in helping us were obvious from the very beginning and consistent throughout the duration of our matter.  I will forever be grateful for all he did for us but, the thing that touched me most is how caring he was towards us.  I cannot thank him and Chelsea enough for the hard work they did on our behalf and for enabling us to move on with our lives." C.B.

"Duplain Law is by far the most helpful firm in Ottawa. Steve gave me guidance to find my faith when all hope was lost. In the end, we succeeded. Thank you Steve Duplain and Chelsea Ross for your awesome work. " K.H.

"Steve worked very hard for my case over a 3 year period, representing me in court, motion after motion, all the way up to the trial. He was very kind, understanding and especially approachable during the long process of separation and divorce. Both he and his paralegal assistant Chelsea, were very knowledgeable and professional, promptly replying to my multitude of questions either by phone or email, going above and beyond to make sure I was as well informed and up to date. Chelsea was especially patient and thorough with researching, drafting, and organizing documents. This team of two is always willing to find the best way to present their client's case to the judge.  I would like to thank them both, time and again with my highest gratitude and utmost appreciation." I.O.

"Steve Duplain was great! His knowledge, patience and understanding was indispensable! I had no knowledge of the legal or family law system in Canada and Steve expertly guided me through every step of the way and made sure I was comfortable and understood what was happening at all times. He always took the time to answer my questions, without judgement and put me at my ease during face to face meetings with the other parties. Highly recommended :)" M.T.

"As a client of Steve Duplain, I can state my complete satisfaction with his professional services. He has been helpful and supportive throughout the court process and he was always available to answer my questions. I sincerely thank him for all he has done to resolve my case." D. B.

"When I first came to Steve Duplain, I was a broken woman. My whole world had fallen apart because of the domestic violence situation I was in. I understood that I needed a good lawyer but I was actually surprised by the healing I received throughout the process; something I attribute to his compassion and validation. All matters that I came to him for were professionally handled above and beyond what I could have expected. Just as he came so highly recommend to me, I as well can very confidently do the same." L.F.
