Key takeaways
  • A birth mother is already a guardian, but a father may be one automatically only in certain situations.
  • A father who is not a guardian can apply for a Guardianship Order using Claim – Family Law Act (CTS3459) and Adult's Statement – Guardianship of Child (CTS3484).
  • Guardianship, not parentage status, is what ties to making decisions about a child in Alberta.

Many unmarried fathers assume that being the father is enough to make decisions for a child. In Alberta, the answer depends on guardianship, and not every father is automatically a guardian.

This article walks through the situations where a father is a guardian, what to do if you are not sure, and how to apply if you are not. Details of your own history matter here, so a lawyer can confirm where you stand.

This article covers the law of Alberta.

Why guardianship matters

In Alberta, the ability to make decisions about a child is tied to guardianship, not 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 guardian of her child.

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. If you are not a guardian, your options are different, so it is worth sorting this out early.

When a father is automatically a guardian

Alberta guidance gives several situations. 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. Other routes include the following.

These rules turn on dates and facts, such as how long you lived together and when you learned of the child. If your situation is close to the line, a lawyer can help you assess it.

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

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

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

What if you only want to see the child?

Someone who is not a guardian, such as a non-guardian parent or a grandparent, applies for a Contact Order using Claim – Family Law Act, Statement – Contact and Affidavit of Service – Applicant. A contact order sets out visits, calls or letters and does not give the person rights or responsibilities over the child.

Guardianship and contact are different things. Guardianship carries decision-making standing, while contact is limited to the time or communication the order sets out. Which one you need depends on what you are trying to achieve.

What to do next

Frequently asked questions

Am I a guardian if I live with the mother when the child is born?

Possibly. A father can be a guardian automatically if he lived with the mother for at least 12 months including when the child was born. Shorter periods may still qualify in some situations, such as certain adult interdependent relationships.

Does signing the birth registration make me a guardian?

Alberta guidance ties guardianship to the Family Law Act rules, not parentage status alone. Check whether one of the listed situations applies to you, such as the 12-month rule or a written agreement.

Can the mother and I agree that I am a guardian?

Yes. A parent is also a guardian if there is a written deal with the other parent saying he is a guardian. Have a lawyer review the wording so it says what you intend.

Which forms do I use to apply for guardianship?

Use Claim – Family Law Act (CTS3459) and Adult's Statement – Guardianship of Child (CTS3484). File at any court in Alberta if there is no existing action with the other party, or at the same court and location if there is.
