Beyond Common Law: A Guide to the Adult Interdependent Relationships Act

The Adult Interdependent Relationships Act is a specialized piece of legislation in Alberta that legally recognizes unmarried couples, and, in some cases, non-romantic partners, who have significantly merged their lives. While other provinces use “common law” as a broad term, Alberta has replaced it with the concept of Adult Interdependent Partners (AIPs). Individuals enter this status automatically after three years of cohabitation or immediately by signing a formal adult interdependent partner agreement. Once recognized, partners gain rights to property division, spousal support, and inheritance, similar to those of married couples. However, in Regina, Saskatchewan, the law differs slightly, using the Family Property Act and a two-year cohabitation rule to provide similar “common law” protections.

Driving with Experience

Imagine you have lived with your partner for five years. You share a mortgage, you’ve raised a dog together, and you both contribute to the same grocery bill. In your mind, you are a family. But in the eyes of the law, are you “official”?

If you are in Alberta or moving between provinces, the term “common law” might be what you use at the dinner table, but the Adult Interdependent Relationships Act is what matters in the courtroom.

Many people believe that simply living together for a few months confers legal rights.

That is a myth. The reality is that unless you meet specific criteria, you could be left with nothing if the relationship ends.

For those in Regina, it is crucial to understand how these inter-provincial laws interact, especially if you have assets in different parts of Canada. Whether you are protecting your home or seeking support, knowing your status under the Adult Interdependent Relationships Act is your first line of defence.

What is the Adult Interdependent Relationships Act?

The Adult Interdependent Relationships Act is an Alberta law that defines the legal status of “Adult Interdependent Partners” (AIPs). 

It applies to two people who live together in a relationship of interdependence for at least three years, or less if they have a child together or have signed a formal agreement. This act provides unmarried individuals with many of the same rights as married spouses, including property division and partner support.

Adult Interdependent Partner vs Common Law: What is the Difference?

The term “common law” is actually quite outdated in many legal circles. While the Canada Revenue Agency (CRA) uses it for tax purposes after just one year of cohabitation, provincial laws have their own definitions.

• Common Law (General): A broad term used across Canada to describe couples who live together but are not married.
• Adult Interdependent Partner (AIP): A specific legal designation under Alberta’s Adult Interdependent Relationships Act.

In Saskatchewan, there is no “Adult Interdependent Relationships Act.” Instead, we use the Family Property Act and the Family Maintenance Act. Under Saskatchewan law, you are considered “spouses” for property purposes after living together in a conjugal relationship for two years.

Adult Interdependent Relationships Act, Ontario

It is common for people to search for the Adult Interdependent Relationships Act (Ontario).

Ontario does not have an “Adult Interdependent Relationships Act.” In Ontario, unmarried couples are governed by the Family Law Act and, notably, do not have the same automatic rights to property division as married couples, regardless of how long they have lived together. This is a stark contrast to the protections found in Western Canada.

How to Become an Adult Interdependent Partner

There are three main paths to gaining legal status under the Adult Interdependent Relationships Act. Understanding these is vital for anyone who wants to avoid a “legal accident” and become a partner without intending to.

1. The Three-Year Rule

If you live with someone in a “relationship of interdependence” for a continuous period of at least three years, the law automatically deems you AIPs.

• You share expenses.
• You are emotionally committed.
• You function as a single domestic unit.

2. The Relationship of Permanence (With a Child)

If you have a child together (by birth or adoption) and live in a relationship of some permanence, you become AIPs immediately. 

The three-year clock does not apply here because the presence of a child is seen as a definitive merger of lives.

3. The Adult Interdependent Partner Agreement

The most direct way to gain status is by signing an adult interdependent partner agreement. This is a formal document that can be used by romantic couples and by platonic partners, such as two siblings or close friends who live together and support each other financially.

Protecting Your Future: The Adult Interdependent Partner Agreement Form

If you want to be sure about your rights, you shouldn’t leave it to a judge to decide if you lived together “long enough.” Many couples choose to use an Adult Interdependent Partner Agreement form to set the record straight from day one.

This form is a regulated legal document. It must be signed by both partners and witnessed by two people. It is essentially a “contract of commitment.”

However, be careful. Signing this form is a double-edged sword. While it grants you rights to insurance and pensions, it also makes you responsible for your partner’s debts and potential spousal support if you split.

If you are looking for an Adult Interdependent Partner Agreement form, it is highly recommended to speak with a lawyer first to ensure you aren’t signing away more than you intended.

Why You Need a Regina Family Lawyer for Inter-Provincial Issues

If you own property in Alberta but live in Regina, or if you moved to Saskatchewan after living as an AIP in Calgary, your legal situation is complex.

The adult interdependent relationships act might apply to your Calgary condo, while the Saskatchewan Family Property Act governs your home in Regina. 

This “conflict of laws” can lead to expensive mistakes if not handled by a professional who understands the Western Canadian landscape.

FAQ: Your Common Law Questions Answered

Can a married person have an adult interdependent partner?

Yes, but only if they are living separately and apart from their spouse. You cannot be in an AIP relationship with a new person while still living with your legally married spouse. The law requires a clear break from the marriage before a new “relationship of interdependence” can be legally recognized.

Does the Adult Interdependent Relationships Act apply to non-romantic partners?

Surprisingly, yes. Unlike traditional “common law,” which requires a conjugal (sexual) relationship, the AIRA allows for platonic partners. This could include two elderly friends who live together to share costs and care for one another. However, if the partners are related by blood, they MUST sign a formal agreement to be recognized.

How do you end an adult interdependent partnership?

You don’t need a divorce to end an AIP status. It ends if you marry each other, if one of you marries someone else, if you sign a formal “Statement of Termination,” or if you live separate and apart for more than one year with the intention to end the relationship.

Is an adult interdependent partner the same as a spouse for taxes?

For federal tax purposes (CRA), the definitions differ. The CRA considers you a common-law partner after 12 months of living together. The 3-year provincial rule applies only to matters of property division, support, and inheritance under provincial law.
