What is this right?
Spousal support is not automatic. The Supreme Court's Bracklow v. Bracklow (1999) set the framework: the person asking has to establish entitlement on at least one of three bases — compensatory (you gave up career opportunities for the family), needs-based (you're at a financial disadvantage after separation), or contractual (an existing agreement governs).
Once entitlement is shown, the numbers come from the Spousal Support Advisory Guidelines (SSAG). They aren't law, but courts use them as the default starting point. Without children, the formula runs 1.5% to 2% of the gross income difference per year of marriage; duration runs half to one year per year of marriage.
After 20 years of marriage — or when the "rule of 65" applies (age plus years of marriage equals 65) — support may be indefinite. Periodic spousal support is taxable to the recipient and deductible to the payer — the structure that lump-sum payments don't get.
When does it apply?
Spousal support may apply to:
- Married spouses under the Divorce Act.
- Common-law partners under provincial legislation — most provinces require 2 to 3 years of cohabitation, though Ontario uses 3 unless you have a child together.
- Cases with a significant income gap between the partners.
What to Do If Your Spouse in Canada Won't Pay Spousal Support
- Establish entitlement first. Identify the basis — compensatory, needs-based, or contractual — before arguing about quantum.
- Exchange full financial disclosure. Income, assets, debts, expenses — both sides.
- Run the SSAG numbers so you know the range a court would land in.
- Negotiate or mediate before litigation. Cheaper, faster, and you keep control of the outcome.
- Think about the tax structure early — periodic vs lump-sum changes the after-tax math significantly.
What should you NOT do?
- Don't assume working disqualifies you. A meaningful income gap can still justify support.
- Don't drag your feet. Long delays in claiming weaken the case.
- Don't quit your job to engineer entitlement. Courts impute income based on earning capacity.
- Don't ignore a support order. Enforcement runs through provincial Maintenance Enforcement Programs — wage garnishment, licence suspension, even jail in egregious cases.
- Don't assume a prenup ends the discussion. Courts will set aside agreements that are unfair or that were signed under pressure or without independent legal advice.
How Alberta differs from federal law
Spousal support in Alberta is available under the federal Divorce Act (for married couples) and the provincial Family Law Act, SA 2003, c. F-4.5 (for unmarried partners who qualify as "adult interdependent partners").
- Under the Family Law Act, adult interdependent partners (couples who have lived together in a relationship of interdependence for 3+ years, or who have a child together, or who have entered into an adult interdependent partner agreement) can claim spousal support, similar to married couples.
- The court considers factors including: the length of the relationship, the roles each partner played, the economic advantage or disadvantage arising from the relationship, the needs and means of each party, and the goal of promoting self-sufficiency within a reasonable time.
- The Spousal Support Advisory Guidelines (SSAGs) — while not law — are widely used by Alberta courts to determine the amount and duration of spousal support based on the length of the marriage and income disparity.
- Spousal support can be ordered as a lump sum, periodic payments, or both. It can also be time-limited or indefinite, depending on the circumstances.
- Spousal support orders can be varied if there is a material change in circumstances, such as a significant change in income, retirement, or the recipient becoming self-sufficient.
Additional Steps in Alberta
To apply for spousal support, file at the Alberta Court of King's Bench (for divorce) or Provincial Court (for Family Law Act claims). Family Justice Services can help with mediation. The Maintenance Enforcement Program (MEP) enforces spousal support orders — contact 1-800-642-3449. For adult interdependent partner claims, you must establish your relationship meets the legal criteria under the Adult Interdependent Relationships Act, SA 2002, c. A-4.5.
Relevant Law: Divorce Act, RSC 1985, c. 3 (2nd Supp.), ss. 15.2–15.3; Family Law Act, SA 2003, c. F-4.5, Part 5 (Support); Adult Interdependent Relationships Act, SA 2002, c. A-4.5
