Adult Interdependent Partner (Common‑Law) Separation in Alberta

What Is an Adult Interdependent Partner (AIP)?

Alberta does not use the term “common‑law spouse.” Instead, the Adult Interdependent Relationships Act (Alberta) (AIRA) defines an Adult Interdependent Partner (AIP) as someone who:

 

  • Has lived with another person in a relationship of interdependence for 3+ years, or
  • Has lived together for less than 3 years but has a child together, or
  • Has signed an Adult Interdependent Partner Agreement

 

AIPs have many of the same rights and obligations as married spouses, especially when it comes to property division and support.

Property Division for Common‑Law Partners (AIPs)

As of January 1, 2020, Alberta’s Family Property Act applies to AIPs. This means:

 

  • Property is divided the same way as for married spouses
  • The focus is on fair and equitable division
  • Both partners must provide full financial disclosure

 

Property subject to division includes:

 

  • The home you lived in
  • Vehicles
  • Bank accounts
  • Investments
  • Pensions
  • RRSPs and TFSAs
  • Business interests
  • Household contents
  • Debts and liabilities

 

Exempt property rules also apply, including:

 

  • Pre‑relationship assets
  • Inheritances
  • Gifts from third parties
  • Certain insurance proceeds

 

However, increases in value during the relationship may still be divisible.

Spousal Support (Partner Support) for AIPs

AIPs may qualify for spousal support under the Family Law Act (Alberta). Entitlement is based on:

 

  • Economic disadvantage from the relationship
  • Income disparity
  • Roles during the relationship
  • Need and ability to pay
  • Length of the relationship
  • Whether the parties have children

 

Once entitlement is established, the Spousal Support Advisory Guidelines (SSAG) are used to determine:

 

  • Amount
  • Duration
  • Whether support should be periodic or lump‑sum

 

Support can be negotiated, mediated, arbitrated, or determined by the court.

Parenting, Decision‑Making, and Child Support

For AIPs with children, parenting issues are governed by the Family Law Act (Alberta). This includes:

 

  • Decision‑making responsibility
  • Parenting time
  • Contact for non‑guardians
  • Child support
  • Section 7 expenses

 

Child support is calculated using the Federal Child Support Guidelines, regardless of marital status.

Ending an Adult Interdependent Relationship

An AIP relationship generally ends when:

 

  • The partners live separate and apart for 1 year, or
  • One partner marries someone else, or
  • The partners sign a written agreement ending the relationship, or
  • One partner dies

 

Once the relationship ends, property division and support claims must be addressed within the applicable limitation periods.

Limitation Periods for AIP Claims

AIPs must act quickly. Key deadlines include:

 

  • 2 years from the date of separation to start a property claim
  • 2 years from the date the AIP relationship ends to claim support
  • 6 months from the date of death to make certain estate claims

 

Missing these deadlines can permanently bar a claim.

Financial Disclosure Requirements

Both partners must provide full, honest disclosure, including:

 

  • Tax returns and Notices of Assessment
  • Bank and investment statements
  • Pension and RRSP information
  • Business financials
  • Property appraisals
  • Debt and loan records

 

Disclosure is essential for a fair and enforceable agreement.

Resolving AIP Separation Issues

AIP separations can be resolved through:

 

  • Negotiation
  • Mediation
  • Arbitration
  • Collaborative law
  • Court applications (if necessary)

 

Most AIP matters settle outside of court with the right structure and guidance.

Adult Interdependent Partner (Common‑Law) Separation in Alberta FAQ

What is an Adult Interdependent Partner (AIP)?

An AIP is Alberta’s legal term for a “common‑law partner.” You are considered AIPs if you:

  • Lived together in a relationship of interdependence for 3+ years, or
  • Lived together and have a child together, or
  • Signed an Adult Interdependent Partner Agreement
    AIPs have many of the same rights and obligations as married spouses.

Yes. Since January 1, 2020, Alberta’s Family Property Act applies to AIPs.
This means property is divided using the same rules as married spouses, including:

  • Equal division of family property
  • Exempt property rules
  • Division of increases in value
  • Full financial disclosure obligations

Property subject to division includes:

  • The home you lived in
  • Vehicles
  • Bank accounts
  • Investments
  • RRSPs, TFSAs, pensions

  • Debts and liabilities

Exempt property (pre‑relationship assets, inheritances, gifts) may still have increases in value that are divisible.

Yes. AIPs may qualify for spousal support under the Family Law Act (Alberta).
Entitlement is based on:

  • Economic disadvantage
  • Income disparity
  • Roles during the relationship
  • Need and ability to pay
  • Length of the relationship

Once entitlement is established, the Spousal Support Advisory Guidelines (SSAG) help determine amount and duration.

Child support for AIPs is calculated using the Federal Child Support Guidelines, just like married parents.
This includes:

  • Base (table) child support
  • Section 7 expenses
  • Shared or split parenting calculations

Evidence may include:

  • Length of cohabitation
  • Joint finances or bank accounts
  • Shared bills or leases
  • Children together
  • A signed AIP Agreement
  • How you presented yourselves publicly

Courts look at the overall nature of the relationship

An AIP relationship ends when:

  • You live separate and apart for 1 year, or
  • One partner marries someone else, or
  • You sign a written agreement ending the relationship, or
  • One partner dies

Yes, and the deadlines are strict.
AIPs must start a claim:

  • Within 2 years of separation, or
  • Within 2 years of the relationship ending, or
  • Within 6 months of a partner’s death (for certain estate claims)

Missing these deadlines can permanently bar your claim.

This is common. Courts may look at:

  • Cohabitation length
  • Financial interdependence
  • Emotional and domestic partnership
  • Whether you functioned as a family unit

Evidence matters, and early legal advice is crucial.

A separation agreement is strongly recommended. It can address:

  • Property division
  • Spousal support
  • Parenting and child support
  • Disclosure obligations
  • Future dispute‑resolution processes

A properly drafted agreement provides clarity and prevents future disputes.

Pre‑relationship assets may be exempt, but:

  • Increases in value during the relationship may be divisible
  • Joint contributions may affect exemptions
  • Tracing may be required to prove exemptions

This is often a complex analysis.

The home is typically considered family property, even if only one partner’s name is on title.
Options include:

  • One partner buying out the other
  • Selling the home and dividing proceeds
  • Temporary exclusive possession (in limited cases)

AIP separations can be resolved through:

  • Negotiation
  • Mediation
  • Arbitration
  • Collaborative law

Court is available when necessary, but most matters settle outside of litigation.

Both partners must provide full financial disclosure, including:

  • Tax returns and Notices of Assessment
  • Bank and investment statements
  • Pension and RRSP information
  • Business financials
  • Property appraisals
  • Debt and loan records

Disclosure is essential for a fair and enforceable agreement.

The first step is a consultation to confirm AIP status, review property and financial issues, and outline your rights and obligations. From there, a tailored strategy is developed to protect your interests and achieve a fair, durable resolution.
