Child's surname

The Civil Code of Québec allows the parents to assign their child only one surname derived from their respective surnames.

Your child may be given a single or compound surname. If you choose to give your child a compound surname, it may not have more than two parts.

If you each have a single surname, your child may be given either or both of your surnames, whether joined by a hyphen or not.


If one parent's surname is Beaulieu and the other's is Lajoie, the child's surname may be

  • Beaulieu;
  • Lajoie;
  • Beaulieu-Lajoie;
  • Beaulieu Lajoie;
  • Lajoie-Beaulieu;
  • Lajoie Beaulieu.

If you both have compound surnames, you may, if you wish, give your child a single surname derived from one of your surnames. If you want to give your child a compound name, you must make a choice, because the child's surname can be composed of only two parts, whether joined by a hyphen or not.


The child of Jean Gagnon-Beaulieu and Marie Bouchard-Lajoie may be given the surname

  • Gagnon;
  • Beaulieu;
  • Lajoie;
  • Bouchard;
  • Beaulieu-Lajoie;
  • Gagnon-Bouchard;
  • Gagnon-Beaulieu;
  • Bouchard-Lajoie;
  • or any other combination that the parents choose.

The surname can not contain a number or an initial.

If the child's maternal or paternal filiation alone is established, the child will bear all or part of the surname of the parent whose name is declared on the Declaration of Birth.
