Key takeaways
  • Since January 1, 2020, the Family Property Act applies to adult interdependent partners as well as married spouses.
  • You can qualify after 3 years together, sooner if you have a child together, or at any point if you signed an adult interdependent partner agreement.
  • Partners generally have 2 years from when they knew or should have known the relationship ended to apply.

If you have lived with a partner without marrying, you may wonder whether Alberta law gives you a right to a share of the property if you separate. The answer often depends on how long you lived together, whether you have children, and when you separated.

This article explains who counts as an adult interdependent partner, what property can be divided, and the time limits that matter. It is general information, and a lawyer can confirm how it applies to your situation.

This article covers the law of Alberta.

Who is an adult interdependent partner?

The Family Property Act, formerly the Matrimonial Property Act, was renamed and the changes took effect January 1, 2020. It now applies to adult interdependent partners as well as married spouses.

Under the Adult Interdependent Relationships Act definition, you may qualify in any of these ways:

Does the Act apply to your separation date?

For adult interdependent partners, the Act applies only if you had not begun living separate and apart, and had not become former partners, before January 1, 2020. The government describes this as applying to those who separate on or after that date.

Existing property division agreements that were enforceable when signed remain enforceable after the change.

What property can be divided?

The Court may divide all property owned by the partners, whether owned jointly or individually. Property acquired after the relationship began is generally distributed equally between adult interdependent partners. An equal split can change where it would not be just and equitable after the Court considers the factors in section 8.

Some property is exempt from distribution. This includes gifts from a third party, inheritances, and property an adult interdependent partner acquired before the relationship began. Growth in the value of exempt property is not automatically exempt, and the Court shares it in a just and equitable way rather than automatically equally.

The Act has no stand-alone debt-division section. Liabilities are considered when the Court decides whether an equal division is just and equitable.

When can you apply, and by when?

Adult interdependent partners can obtain a family property order once they have become former adult interdependent partners. They can also apply while separate and apart if the other partner is transferring property to defeat the claim or dissipating property. Living under one roof or sharing some household services does not prevent a finding of separation.

You have 2 years from the date you knew, or should have known, that the relationship had ended. A single reconciliation period of up to 90 days is not counted when calculating time for spouses, and a resumed relationship of up to 90 days aimed at reconciliation does not restart the process for partners.

Agreements and protecting property

Adult interdependent partners may opt out of the default rules by signing their own agreement dividing property differently. If they do not, the rules apply to property obtained after the start of the relationship.

Once proceedings start, a party who knows of them must not dispose of or encumber household goods or remove household items from the home without consent or a court order. The Court can also restrain a planned transfer or gift that could defeat a claim, and can do so without notice to the other party.

What to do next

A claim is started with a Statement of Claim for Division of Family Property (Form FL-2), or Form FL-3 where combined with a divorce claim. Each party must also file a sworn statement disclosing all their property. Confirm current forms on the Alberta Courts website.

Frequently asked questions

Do we need to live together for 3 years to qualify?

Not always. You can qualify with less than 3 years if the relationship has some permanence and you have a child together. You can also qualify for any period if you signed an adult interdependent partner agreement.

Is the Act the same for common-law partners and married spouses?

The Act now applies to both. The equal-sharing rule for partners covers property acquired after the relationship began. The application time limits and starting points differ between spouses and partners.

What if I separated before 2020?

The Act applies to partners only if they had not begun living separate and apart, and had not become former partners, before January 1, 2020. A lawyer can confirm how your situation is treated.

Does it matter whose name is on the home?

The Court may divide property owned jointly or individually. A home in one partner's name can still be divided, subject to exemptions such as property owned before the relationship.
