How long do you have to be common-law to claim partner support in Alberta?

1 Jul 2026 6 min read No comments Family Law & Divorce Alberta
💡

In Alberta, you must live together in a relationship of interdependence for at least 3 continuous years to be considered Adult Interdependent Partners and claim partner support. However, if you share a child together by birth or adoption, this timeline does not apply, and you gain this status immediately.

Navigating the complex rules around common-law relationships and financial support can be incredibly confusing. Whether you are living in Fort McMurray, Calgary, Lethbridge, or Edmonton, understanding your rights regarding partner support in Alberta is essential after a breakup to ensure your financial stability.

First, it is important to know that Alberta law does not officially use the term common-law. 📚 Instead, the legal term in this province is Adult Interdependent Partner (AIP). Once you qualify as an AIP under the Adult Interdependent Relationships Act, your rights to claim financial support are very similar to those of legally married couples claiming spousal support.

Because proving your status and calculating support amounts can be tricky, getting proper legal advice is highly beneficial. We encourage you to search our directory to find a compassionate local lawyer or law firm who can evaluate your situation, explain the legal nuances, and fight for the financial support you deserve.

Understanding the Adult Interdependent Relationships Act

To fully grasp how partner support works, you need to understand the legislation behind it. In Alberta, the Adult Interdependent Relationships Act defines exactly who qualifies for support. You are legally considered an AIP if you have lived with someone in a relationship of interdependence for three continuous years, or if you live together and share a child, or if you have signed a formal Adult Interdependent Partner Agreement.

A relationship of interdependence means more than just being roommates. 🧡 The court looks at several factors, including whether you share a romantic relationship, how you present yourselves to your community, whether you share bank accounts, and how you divide household chores. Proving these elements is crucial if your ex-partner denies that you were truly living as common-law.

Step-by-Step Process for Claiming Partner Support in Alberta

Claiming partner support requires you to prove both your relationship status and your genuine financial need. If you are seeking financial assistance after a separation, the legal process generally follows these foundational steps through the Alberta justice system.

Step 1: Confirming Your AIP Status

Before you can ask for a single dollar, you must legally prove you were Adult Interdependent Partners. 👥 This means showing concrete evidence that you lived together for three years, lived together and share a child, or signed a formal legal agreement acknowledging your partnership.

Step 2: Assessing Financial Need and Entitlement

Just because you were an AIP does not automatically mean you will get support. You must prove entitlement. This means showing that you suffered a financial disadvantage because of the relationship (like giving up your career to raise children) or that you simply cannot meet your basic living needs without financial help from your higher-earning ex-partner.

Step 3: Calculating the Amount and Duration

If you are entitled to support, the next step is figuring out how much and for how long. 💰 Lawyers and judges in Canada rely heavily on the Spousal Support Advisory Guidelines (SSAG) to calculate a fair range. The SSAG uses complex formulas based on both partners’ incomes and the total length of the relationship to determine appropriate support levels.

Step 4: Creating an Agreement or Selecting the Right Court

Ideally, your law firm will help you negotiate a fair monthly amount with your ex-partner and draft a binding separation agreement. If your ex simply refuses to pay, you will need to file a formal claim. Crucially, if you are only seeking partner support without a property division, you do not have to file at the Court of King’s Bench; you can file your Family Law Act claim in either the Court of King’s Bench or the Alberta Court of Justice. The Alberta Court of Justice is often a significantly faster and cheaper option for standalone support claims.

However, if you choose to proceed in the Court of King’s Bench, you must comply with the Family Focused Protocol (FFP) implemented on January 2, 2026 (NPP 2026-01). This protocol mandates that partners in Court of King’s Bench support disputes must participate in alternative dispute resolution (ADR)-such as completing at least one hour of mediation-before a judge will hear their application. Notably, the Alberta Court of Justice has not adopted these changes, meaning claims filed there proceed under standard provincial family rules without the FFP’s mandatory pre-court ADR requirements.

How Much Does it Cost in Alberta?

Seeking partner support involves some upfront expenses, but securing long-term financial stability is usually worth the initial investment. Here are the typical costs you might encounter in Alberta as of June 2026:

  • Court Filing Fees: Exactly $100 CAD to file a Family Law Act claim for support at either the Court of King’s Bench or the Alberta Court of Justice.
  • Income Tax Records: $0 CAD to request your own notices of assessment from the CRA, which are mandatory for support calculations.
  • Mediation Services: Around $200 to $500 CAD per hour if you choose to negotiate smoothly out of court.
  • Lawyer Retainers: Expect to pay $2,500 to $5,000+ CAD to have a lawyer handle a standard support claim, depending on overall complexity.

It is crucial to remember that periodic partner support is generally considered taxable income for the person receiving it and tax-deductible for the person paying it, according to CRA rules. 💲 Always consult an accountant or tax professional when finalizing your support amounts to avoid unexpected tax bills.

How Long Does the Process Take?

Getting a final partner support order can take anywhere from a few weeks to several months. If your ex-partner acknowledges their financial responsibility and cooperates, a lawyer can draft and finalize a support agreement in less than a month, allowing payments to start almost immediately.

An interim order is a temporary decision made by a judge to provide you with financial help while you wait for the final trial, which can usually be secured within a few months of filing your initial application. Note that if you are proceeding in the Court of King’s Bench, you must first satisfy the mandatory pre-court ADR requirements under the 2026 Family Focused Protocol.

Be intensely aware of the strict time limits for making a claim. In most cases, you must bring your formal claim for partner support within two years of the date your relationship ended. Missing this deadline could mean losing your right to support forever, so acting quickly is incredibly important.

Frequently Asked Questions (FAQ)

What if we lived together for 2 years and 11 months?

Under Alberta law, the 3-year requirement is very strict. If you did not share a child and lived together for less than three continuous years, you generally do not qualify as Adult Interdependent Partners and cannot claim partner support.

Do same-sex couples qualify for partner support?

Absolutely. The Adult Interdependent Relationships Act applies to all couples in Alberta, regardless of gender or sexual orientation, provided you meet the time or child requirements.

Can we sign an agreement to opt out of partner support?

Yes. Many couples sign a Cohabitation Agreement before or during their relationship that limits or entirely waives the right to claim partner support if they separate. However, a judge can overturn this if it is deemed extremely unfair.

Is partner support the same as child support?

No. Partner support is meant to help the lower-income spouse meet their personal living expenses. Child support is a separate, mandatory payment intended strictly for the financial care and well-being of the children, regardless of parenting time.

Can two platonic friends be Adult Interdependent Partners?

Yes, but it is exceptionally rare. Two people who are not in a romantic relationship can become AIPs if they live together in a relationship of interdependence and intentionally sign an Adult Interdependent Partner Agreement.
