Key takeaways
  • In Alberta, the power to make decisions about a child comes from guardianship, not from being a parent alone.
  • An unmarried father can be a guardian automatically in some situations, such as living with the mother for at least 12 months including when the child was born.
  • If you are not a guardian, you can apply for a Guardianship Order using Claim – Family Law Act (CTS3459) and Adult's Statement – Guardianship of Child (CTS3484).

If you are an unmarried father in Alberta, you may wonder whether you have a legal say in major decisions about your child. The answer depends less on whether you are named as a parent and more on whether you are a guardian.

This article explains in plain words how guardianship works under the Family Law Act, when a parent is a guardian automatically, and how a parent who is not a guardian can apply. Your situation may have details that change the answer, so a lawyer can confirm where you stand.

This article covers the law of Alberta.

Guardianship, not parentage, decides who makes decisions

In Alberta, the ability to make decisions about a child is tied to guardianship, not to parentage status. A guardian under the Family Law Act is a guardian for all legal purposes, and in most cases a child's parents are also guardians.

A birth mother is already a legal guardian of her child under the Family Law Act. For a father who is not married to the mother, the question is whether he meets one of the routes to guardianship below.

When an unmarried father is a guardian automatically

A parent who is not the birth mother can be a guardian automatically if, for example, he lived with the mother for at least 12 months including when the child was born, or was married to her when the child was born.

There are other routes as well. These include the following:

If you are not a guardian: applying for a Guardianship Order

A parent who is not a guardian can apply for a Guardianship Order. So can an adult who has had care and control of the child for at least 6 months. The forms are Claim – Family Law Act (CTS3459) and Adult's Statement – Guardianship of Child (CTS3484).

If there is no existing action with the other party, the application can be filed at any court in Alberta. If there is an existing action, file at the same court and location. In Greater Edmonton, Calgary, Red Deer or Grande Prairie the Family Justice Strategy may apply first. If you do not attend court, the judge may make an order in your absence.

What guardianship means after separation

After separation, guardians who agree can keep exercising guardianship powers without a court order. If they disagree, either guardian can apply for a parenting order. That order can divide parenting time, assign specific responsibilities, or set a process for resolving future disputes.

If guardians cannot agree, a judge decides based on the child's best interests, aiming to protect the child's physical, psychological and emotional safety. Factors include the child's care history, the child's views, the benefit of relationships with both parents or guardians, and any history of family violence.

If you are not a guardian, for example a grandparent or a non-guardian parent, you can apply for a Contact Order. It sets out visits, calls or letters and does not give you rights or responsibilities over the child.

What to do next

Before filing a Family Law Act application in the Court of King's Bench, you generally must take the Parenting After Separation course. Whether it applies to your guardianship application is worth confirming with a lawyer.
