About MJ Gauthier Professional Corporation

MJ Gauthier Professional Corporation is a sole-practitioner law firm in Rockland, Ontario, led by Marie-Josee Gauthier. Gauthier earned a B.Sc., Soc. and an LL.B. from the University of Ottawa in 1993 and has practiced law since 1995. The firm concentrates on three areas: family law, wills and estates, and residential real estate, working out of an office on Laurier Street in Rockland.

In family law, the practice handles divorce and separation, custody and access, child and spousal support, and division of property, and since 2000 has taken court appointments through the Office of the Children's Lawyer to represent children in family proceedings. Wills and estates work covers planning for the distribution of property, an area the firm describes as increasingly complex. The real estate practice handles residential purchases, sales, and mortgages. MJ Gauthier Law serves clients in French and English, reflecting a community where both languages are in daily use.

In the community

  • Gauthier volunteered for 13 years at Interlude House, a shelter serving survivors of domestic abuse, an experience that informed an understanding of the issues facing survivors when they separate.
  • Gauthier served as vice-president of the United Way from 2010 to 2011.
