Alberta Interdependent Relationships

Need To Know

Alberta’s Adult Interdependent Relationship (AIR) is a unique legal status that gives unmarried partners — and in some cases, close friends or relatives — rights similar to married couples. Defined under the Adult Interdependent Relationships Act (AIRA), this status can form automatically after three years of cohabitation, after having a child together, or through an agreement. Being in an AIR affects property division, support, inheritance, and decision-making rights. Understanding this relationship type — and protecting yourself with a cohabitation agreement — is crucial for managing your financial and legal responsibilities in Alberta.

Understanding relationships in Alberta can be confusing because the law recognizes more than just marriage or common-law partnerships. Alberta has a unique category of relationships called Adult Interdependent Relationship (AIR), defined under provincial law. This status can give you rights and responsibilities similar to those of married spouses, even if you never had a wedding.

For Alberta couples, it is important to understand how provincial law defines these partnerships, how they are created, and what legal implications come with them.

What is an Adult Interdependent Relationship in Alberta?

An Adult Interdependent Relationship is a legal relationship defined in the Adult Interdependent Relationships Act (AIRA). It is designed to cover situations where two people are in a committed, interdependent partnership but are not married.

Adult Interdependent Relationships Act

The Adult Interdependent Relationships Act (AIRA) came into effect in 2003. Its goal was to extend certain legal rights and obligations to unmarried partners who are emotionally and financially interdependent. The Act is unique to Alberta and goes beyond what many other provinces recognize as common-law relationships.

Who qualifies as an Adult Interdependent Partner (AIP)?

An Adult Interdependent Partner (AIP) can be:

  • Two people who live together in a relationship of interdependence for at least three years, or
  • Two people who live together in a relationship of interdependence of some permanence and have a child together by birth or adoption, or
  • Two people who sign an Adult Interdependent Partner Agreement to formalize their relationship.

Importantly, AIPs don’t have to be romantic partners. The law allows for family members or even friends who share interdependent lives to qualify, though restrictions apply.


Differences Between Adult Interdependent Relationship and Marriage

While both marriages and AIRs create legal rights and responsibilities, they differ in key ways:

  • Formality: Marriage requires a license and ceremony; AIRs can arise automatically after three years of cohabitation or through an agreement.
  • Scope of recognition: Marriages are recognized across Canada and internationally. AIRs are unique to Alberta, though other provinces may recognize them in limited contexts.
  • Termination: Ending a marriage requires divorce; ending an AIR can be achieved by separation, new marriage, or agreement.


Becoming an Adult Interdependent Partner

Steps to establish Alberta Interdependent Partner status

You can become an AIP in one of three ways:

  1. Living together in an interdependent relationship for at least three years.
  2. Living together with some permanence and having a child together.
  3. Signing an Adult Interdependent Partner Agreement (this option is not available to married couples or people under 16).

Exceptions to Creating an Adult Interdependent Relationship

You cannot enter into an AIR if:

  • You are under the age of 16.
  • You are already married.
  • You are already in another Adult Interdependent Relationship.
  • You are closely related by blood or adoption (except in limited caretaker situations).


How Does an Adult Interdependent Relationship Impact Your Rights?

Being an AIP carries significant legal consequences. You may have rights and responsibilities related to:

  • Property division under Alberta’s Family Property Act.
  • Spousal support obligations, even without marriage.
  • Inheritance rights, such as being recognized as a dependent under the Wills and Succession Act.
  • Decision-making rights, such as health care directives and next-of-kin status.

This means that once AIR status is established, your partner could have claims on your property or estate, even if you never intended that outcome.


Adult Interdependent Relationship Benefits

There are also important benefits to AIR recognition:

  • Access to spousal benefits like health coverage, pensions, and insurance.
  • Eligibility for tax benefits and federal/provincial support programs.
  • Legal recognition of caregiving relationships, which can be crucial for non-romantic partnerships.

For many couples and families, AIR status provides needed security and fairness.


How to Legally Protect Your Alberta Interdependent Relationship

Because AIRs can arise automatically, many people do not realize they are in one until a legal issue arises. To protect yourself:

  • Consider a Cohabitation Agreement: This agreement clarifies property division, financial responsibilities, and expectations. Yes, AIPs can sign one, and it is strongly recommended.
  • Review your estate planning: Wills, powers of attorney, and beneficiary designations should reflect your wishes. Without them, your AIP may have claims you did not anticipate.
  • Review Jointly’s free Agreement Starter Kit or get legal advice: Understanding your rights early can prevent conflict later.


Ending an Adult Interdependent Relationship

An AIR can end when:

  • The partners live apart for at least one year with the intention to end the relationship.
  • One partner marries someone else.
  • The partners sign an agreement to end the relationship.
  • A court declares the relationship is over.

Ending an AIR still involves rights and responsibilities. For example, property and support obligations may continue, so it is important to address these with legal guidance or through formal agreements.


FAQs

How long do you need to live together to become an AIP?

Generally, three years of cohabitation, unless you have a child together or sign an AIP agreement.

Do AIPs have the same rights as married couples?

In many provincial contexts, yes — especially regarding property division, spousal support, and estate rights. But AIRs are not always recognized outside Alberta.

Can same-sex partners be AIPs in Alberta?

Yes. Same-sex partners can qualify as Adult Interdependent Partners under the Act.

Do AIPs need to register their relationship with the government?

Not necessarily. AIR status can arise automatically through time and cohabitation. Signing an AIP agreement is one way to formalize the relationship, but registration is not required.

Can AIPs get a cohabitation agreement?

Yes. A cohabitation agreement is one of the best tools for AIPs to clarify financial responsibilities and protect themselves in case of separation.
