Can a Stepparent Be a Guardian of a Child in British Columbia?

This answer covers the law of British Columbia.

Not automatically. If a guardian marries or enters a marriage-like relationship with a person who is not a guardian, that person does not become a guardian by reason only of the relationship. A stepparent is a guardian only if a court appoints them.

To be appointed, you apply to the court under section 51, giving details about your plans for the child's care and your own history. If the child is 12 or older, a non-parent appointment needs the child's written approval unless the court is satisfied the appointment is in the child's best interests. You can apply at the same time for a parenting order allocating parental responsibilities and parenting time. A person who is not a parent cannot become a guardian by agreement; only a parent can.

This matters because only a guardian may have parental responsibilities and parenting time. Without an appointment, a stepparent may still be able to ask for a contact order, which the court decides on the child's best interests. Whether an appointment is right for your family depends on the facts, and a lawyer can help you weigh it.
