Key takeaways
  • Unmarried partners cannot use the Divorce Act, but may claim support under Alberta's Family Law Act if they are adult interdependent partners.
  • You can become an adult interdependent partner by living in a relationship of interdependence for at least 3 continuous years, by having a child of the relationship in a relationship of some permanence, or by signing an adult interdependent partner agreement.
  • Having a child together does not by itself create an entitlement to support.

You lived with someone for years, shared a home and bills, and never married. Now the relationship has ended and you wonder whether you can ask for support. In Alberta, the answer depends on whether the law treats the two of you as adult interdependent partners.

This article explains how that status works, what else must be shown before a court can order support, and what to do next. It is general information, and your own facts matter a great deal.

This article covers the law of Alberta.

Why the Divorce Act does not apply to you

The federal Divorce Act covers married couples who are seeking a divorce. Unmarried partners cannot use it. Instead, support between unmarried partners is dealt with under Alberta's Family Law Act, which places a support obligation on every spouse or adult interdependent partner.

A court can order one partner to pay support to the other when an application is made. The Family Law Act also includes a former adult interdependent partner, so you can usually apply after the relationship has ended.

Who counts as an adult interdependent partner

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. Living together is not enough on its own; the nature of the relationship matters.

Under the Adult Interdependent Relationships Act, you become an adult interdependent partner in one of three ways:

Exceptions that can change the answer

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

What else must be shown before support is ordered

Being a partner is only the first step. A support order may be made only if one of the following applies:

If these tests are met, the court looks at each person's condition, means, needs and other circumstances, including how long you lived together and the roles each of you performed. It also considers the payer's legal obligation to support someone else and what others living in either household contribute to expenses. The aims include recognizing economic advantages and disadvantages from the relationship, relieving hardship from the breakdown and promoting self-sufficiency within a reasonable time.

If child support is also being sought, child support gets priority.

What to do next

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

Frequently asked questions

Can I claim support if we never married?

Possibly. If you were adult interdependent partners, the Family Law Act allows a court to order support between you, but only if one of these applies: you have a declaration of irreconcilability, you are living separate and apart, you are in discord and cannot reasonably be expected to live together, or one of you has without sufficient cause refused or neglected to provide necessaries. Unmarried partners cannot use the Divorce Act.

How long do we need to have lived together?

Generally a continuous period of at least 3 years in a relationship of interdependence. A relationship of some permanence with a child of the relationship can also qualify, and two people can become partners right away by signing an adult interdependent partner agreement.

Does having a child together entitle me to support?

Not by itself. A child can affect whether you qualify as partners, but entitlement still depends on the other requirements.

Do we have to be living apart to get an order?

Not always. Living separate and apart is one route, but a declaration of irreconcilability or discord where you cannot reasonably be expected to live together can also qualify.
