Key takeaways
  • Living together alone is not the test; the relationship must be one of interdependence.
  • You can qualify with three continuous years together, a child of the relationship, or a written agreement.
  • An unmarried partner who is not an adult interdependent partner has no intestacy share under Part 3.

Many couples in Alberta live together for years without marrying and call themselves common-law. When one partner dies without a will, the survivor often assumes they will inherit. Whether they do depends on a legal test that is different from the everyday meaning of common-law.

This article explains how the test works, who can qualify, and what happens if you do not.

This article covers the law of Alberta.

Living together is not enough on its own

The intestacy rules in Alberta speak of a spouse or an adult interdependent partner, and the second term has the meaning given in the Adult Interdependent Relationships Act. That Act defines a relationship of interdependence as one 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 alone is not the test.

A partner who qualifies has the same intestacy entitlements as a surviving spouse.

The three ways to qualify

RouteWhat is required
Time togetherLiving together in a relationship of interdependence for a continuous period of not less than 3 years
ChildLiving together in a relationship of interdependence of some permanence, with a child of the relationship by birth or adoption, and no three-year minimum
AgreementAn adult interdependent partner agreement under section 7, with no minimum period of living together

If the relationship is questioned in court proceedings, the person claiming to be the partner has the onus of proving it.

What you would receive if you qualify

On a net estate of $200,000 with one child from a prior relationship, that is $150,000 to the partner and $50,000 to the child.

These rules apply to deaths on or after February 1, 2012, and the estate is measured by its net value after debts, charges, and funeral and administration expenses. The $150 000 figure is set by the Preferential Share (Intestate Estates) Regulation, which expires on December 31, 2031, so the figure may be reviewed or re-made by then.

Situations that can stop you qualifying

If you do not qualify

An unmarried partner who is not an adult interdependent partner has no intestacy share under Part 3 of the Wills and Succession Act. If there is no spouse, partner or descendant, the estate passes to relatives by blood or adoption, and relatives by marriage are not included. The order runs from the parents, to siblings, nieces and nephews, then grandparents and their descendants, and then great-grandparents and their descendants.

Where descendants inherit, the estate is divided into one share for each surviving child and one for each deceased child who left descendants.

Whether you qualify can turn on detailed facts, and there may be other routes to a claim depending on your situation, so a lawyer can confirm your options.

What to do next

Only the personal representative named in a Court grant has authority to act for the estate once it issues. People entitled in an intestacy may nominate someone to administer the estate.

Where there is no will, the order of priority to apply for a grant starts with the surviving spouse or adult interdependent partner, followed by a child.

Frequently asked questions

Is a common-law partner treated like a spouse if there is no will?

Only if they are an adult interdependent partner. A qualifying partner has the same intestacy entitlements as a spouse.

How long do we have to live together to qualify?

A continuous period of not less than 3 years in a relationship of interdependence qualifies. A child of the relationship or a written partner agreement can qualify you without that period.

What if I am not a qualifying partner?

An unmarried partner who is not an adult interdependent partner has no intestacy share under Part 3. The estate then goes to relatives by blood or adoption.

Do I have to prove we were partners?

In court proceedings, the person claiming to be an adult interdependent partner has the onus of proving the relationship.
