Unlike child support, spousal (and partner) support in Alberta doesn't follow a strict, legally binding formula — but the Spousal Support Advisory Guidelines (SSAG) provide a widely used framework that most lawyers, mediators, and judges reference to estimate a reasonable range.
Two Legal Bases for Spousal Support
- Compensatory support — compensates a spouse for economic disadvantage arising from the relationship or its breakdown (e.g., leaving the workforce to raise children)
- Non-compensatory (needs-based) support — addresses one spouse's financial need and the other's ability to pay, independent of any specific economic sacrifice
Many cases involve a combination of both.
What the SSAG Framework Considers
- Length of the relationship (including any period of cohabitation before marriage)
- Income disparity between the spouses
- Whether there are dependent children and who has primary parenting time
- Each spouse's age, health, and ability to become self-sufficient
The SSAG produces a range for both amount and duration — not a single fixed number — which is one reason spousal support negotiations often take more back-and-forth than child support.
Duration: "With Child Support" vs. "Without Child Support" Formulas
The SSAG uses different formulas depending on whether dependent children are involved, since child-related formulas account for the interaction between child support and spousal support obligations on the paying spouse's remaining income.
Common Misunderstandings
- Spousal support is not automatic — entitlement must be established first, before amount and duration are even discussed
- A short marriage with no children and comparable incomes may result in little or no spousal support entitlement
- Support obligations can be reviewed and varied later if circumstances change materially (job loss, retirement, remarriage, or a new relationship)
Frequently asked questions
Is spousal support taxable?
Periodic spousal support payments are generally taxable to the recipient and deductible to the payor, while lump-sum payments are typically treated differently — confirm the tax treatment with your lawyer and accountant before finalizing an agreement.
How long does spousal support last?
Duration depends on the length of the relationship and other SSAG factors; shorter marriages often have defined end dates, while longer marriages may result in indefinite (reviewable) support.
Can spousal support be changed after it's ordered?
Yes, where there's a material change in circumstances, either party can apply to vary the amount or duration.
