Family relationships and civil union

A civil union is prohibited between close relatives for moral and physiological reasons. As a result, you cannot form a civil union with a person who is your:

  • brother or sister;
  • half-brother or half-sister;
  • parent or child.

This rule applies to both biological and adoptive relatives.

However, you may form a civil union with certain other relatives, such as:

  • your cousin;
  • a person who is related to by marriage only, such as the former spouse of your uncle or aunt, or your former sister-in-law.
