Key takeaways
  • Unmarried partners cannot use the Divorce Act, but may claim partner support under Alberta's Family Law Act.
  • Adult interdependent partner status generally requires three continuous years in a relationship of interdependence, or a child together plus some permanence.
  • Signing an adult interdependent partner agreement can create the status immediately.

If you lived with a partner but never married, you may wonder whether you can claim support after separation. In Alberta, the answer often turns on whether you were adult interdependent partners.

This article explains what that term means, how long a relationship generally has to last, and where the rules change.

This article covers the law of Alberta.

Support for partners who were never married

Unmarried partners cannot use the Divorce Act. Instead, Alberta's Family Law Act says every spouse or adult interdependent partner has an obligation to provide support for the other. On application, the court may order one to pay support to the other.

A former adult interdependent partner counts too. The Alberta Court of Justice describes this as Adult Interdependent Partner Support.

The Divorce Act covers married couples seeking a divorce. Married spouses who are not seeking a divorce can still claim spousal support under the Family Law Act, and the Alberta Court of Justice can order spousal support for a married former spouse.

Who is an adult interdependent partner?

Under the Adult Interdependent Relationships Act, a person is an adult interdependent partner of another if any one of these applies:

A relationship of interdependence is a relationship outside marriage in which two people share one another's lives, are emotionally committed to one another, and function as an economic and domestic unit.

The Alberta Court of Justice notes that having a child together does not, in itself, give rise to entitlement.

Exceptions that change the answer

SituationWhat the rules say
Signed an agreementPeople who live or intend to live together can become partners immediately, without waiting 3 years, by signing an agreement in the form set by regulation.
Related by blood or adoptionThey can become partners only by entering an agreement; living together alone does not qualify.
Still married to someone elseA married person cannot become an adult interdependent partner while living with his or her spouse.

Conditions for a support order

Being a partner is not enough by itself. A support order may be made only if one of these is true:

The court may declare there is no prospect of reconciliation on application by one or both partners, which is one route to qualifying.

The court then looks at each party's conditions, means, needs and other circumstances, including the length of cohabitation and the functions each performed. It also considers the payer's legal obligation to support another person, and the extent to which others living with the payer or the recipient contribute to household expenses. Its objectives include recognizing economic advantages and disadvantages from the relationship and relieving hardship from its breakdown. If child support is also sought, it gets priority.

Misconduct is generally not considered, except conduct that arbitrarily or unreasonably precipitates, prolongs or aggravates the need for support, or unreasonably affects the payer's ability to pay. While an application is waiting to be decided, the court may make an interim order, which must follow these factors and objectives so far as practicable given the need for interim support.

After an order is made

The court may vary, suspend or terminate a support order or any part of it. For partner support, the ground is a change in the condition, means, needs or other circumstances of either party.

The Spousal Support Advisory Guidelines are not law. How far they are used for partner support in Alberta depends on your situation, so it is worth confirming with a lawyer. They do not decide entitlement: entitlement must be established first, and an income gap alone is not enough.

What to do next

Whether you qualify depends on your facts, so a lawyer can confirm how the rules apply to your relationship.

Frequently asked questions

Can a common-law partner claim spousal support in Alberta?

Possibly. If you are an adult interdependent partner, the Family Law Act allows the court to order support. Status generally needs 3 continuous years, or a child with some permanence, or a signed agreement.

Does having a child together qualify me?

Not automatically. The relationship must have some permanence where there is a child, and the Alberta Court of Justice notes that having a child together does not itself give rise to entitlement.

Can we sign an agreement to become partners right away?

Possibly. Two people who live or intend to live together can become partners immediately by signing an agreement under section 7 in the form set by regulation. A married person cannot become an adult interdependent partner while living with his or her spouse. Related persons can become partners only by entering such an agreement.

Who collects the support payments?

Unless the parties agree or the court orders otherwise, the Maintenance Enforcement Program collects and enforces them in Alberta.
