Couple’s frequently assume that getting married changes a bride’s name. Getting married does not legally change a name. Although either partner may legally assume their spouse’s name (you may choose to use your spouse’s surname), this does not constitute a legal change of name.
You must elect to legally change your surname (family name) as a result of marriage or a common-law relationship. You may change your surname to the surname your partner had immediately before the union or to a surname combining both your surnames in either order. If you change your name within 90 days after your marriage, there is no fee.
For more information regarding changing your name, go to the Ontario Government Website or contact the Office of the Registrar General at 1-800-461-2156, or (416) 325-8305 in the Toronto area.
