Nova Scotia Canadian Spousal Support (SSAG) Estimator

Nova Scotia courts use the Spousal Support Advisory Guidelines (SSAG) to calculate support ranges. The without-child formula multiplies 1.5% to 2.0% of the gross income difference by the years of marriage, producing a low-to-high monthly range. For couples with dependent children, the with-child formula targets 40% to 46% of combined Individual Net Disposable Income (INDI) for the recipient. Nova Scotia's Supreme Court (Family Division) treats these ranges as the starting point in most cases.

The Rule of 65 grants indefinite spousal support when the years of marriage plus the recipient's age at separation equals or exceeds 65. For example, a 55-year-old recipient from a 10-year marriage qualifies (55 + 10 = 65). This rule does not apply to marriages under 5 years. Indefinite support means no fixed end date is set initially, though the order remains subject to future variation or review based on changed circumstances.

Under the SSAG, duration ranges from 0.5 to 1.0 years for each year of marriage under the without-child formula. A 12-year marriage produces a 6-to-12-year duration range. Support becomes indefinite for marriages lasting 20 years or longer, or when the Rule of 65 applies. Indefinite does not mean permanent—courts may terminate support if the recipient achieves self-sufficiency or circumstances materially change.

Yes, periodic spousal support payments in Canada remain fully tax-deductible for the payor and taxable income for the recipient under the Income Tax Act. This differs significantly from the United States, where spousal support lost its tax-deductible status in 2019. To qualify, payments must be made under a written separation agreement or court order. Lump-sum payments are neither deductible nor taxable.

The without-child formula applies when there are no dependent children. It calculates spousal support as 1.5% to 2.0% of the gross income difference between spouses, multiplied by the years of marriage or cohabitation. After 25 years, amounts cap at 37.5% to 50% of the income difference. The SSAG applies to payor incomes between the $20,000 floor and $350,000 ceiling.

The with-child formula applies when the higher-income spouse pays both child support and spousal support. It uses Individual Net Disposable Income (INDI)—gross income minus child support obligations minus taxes plus benefits—for each spouse. The formula iterates to find the spousal support amount that leaves the recipient with 40% to 46% of combined INDI. Duration is initially indefinite but tied to the youngest child's school status and relationship length.

Yes, spousal support can be varied upon demonstrating a material change in circumstances under section 17(4.1) of the Divorce Act or Nova Scotia's Parenting and Support Act. Common material changes include job loss, significant income changes, retirement, serious illness, or the recipient's cohabitation with a new partner. The change must not have been contemplated in the original order or agreement. Courts may then recalculate support using current incomes and the SSAG.

Yes, under Nova Scotia's Parenting and Support Act, unmarried partners may claim spousal support if they cohabited in a conjugal relationship for at least 2 years continuously, or if they have a child together regardless of cohabitation length. Common-law spousal support uses the same SSAG formulas as married couples. However, unlike married spouses, common-law partners do not automatically share property under Nova Scotia law unless they have a registered domestic partnership.
