Quebec spousal support (called "support" or "alimentary obligation" under Quebec civil law) is governed by both the Civil Code of Quebec, articles 585-596 and the Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), s. 15.2. Unlike most Canadian provinces, Quebec uses a civil law system where married and civil-union spouses may claim support, but common-law (de facto) partners have no right to spousal support under CCQ art. 585. An alimony calculator for Quebec applies the Spousal Support Advisory Guidelines (SSAG) formulas, producing ranges of 1.5% to 2% of the gross income difference per year of marriage (without child support formula) or net disposable income sharing (with child support formula). Courts retain full discretion to deviate from these ranges based on the needs and means of each spouse under CCQ art. 587.

How Does the Quebec Alimony Calculator Work?
The Quebec alimony calculator estimates spousal support by applying the Spousal Support Advisory Guidelines (SSAG) formulas to each spouse's income, the length of the marriage, and whether dependent children are involved. The SSAG produces a range (low, mid, and high) rather than a single fixed amount, giving Quebec Superior Court judges discretion to set support within that range. According to the Department of Justice Canada (2008), the SSAG "without child support" formula calculates support at 1.5% to 2% of the difference between the spouses' gross incomes, multiplied by the number of years of cohabitation, up to a maximum of 50% of the gross income difference.
Quebec courts are not legally bound by the SSAG because these guidelines are advisory, not legislated. However, Quebec Superior Court judges increasingly reference the SSAG ranges as a starting point when determining spousal support amounts. The final award depends on the factors listed in CCQ art. 587: the needs and means of both spouses, their circumstances, and the time the support creditor needs to become self-sufficient. A Quebec alimony calculator provides a useful estimate, but the court retains ultimate discretion under both federal and provincial law.
What Are the Two SSAG Formulas for Calculating Spousal Support?
The Spousal Support Advisory Guidelines use two distinct formulas depending on whether the couple has dependent children. The "without child support" formula applies when no children require support and calculates a range of 1.5% to 2% of the gross income difference multiplied by years of marriage, capped at 50%. The "with child support" formula uses net disposable income sharing and applies when child support obligations exist concurrently.
Without Child Support Formula
The without child support formula under the SSAG calculates Quebec spousal support as follows: take the difference between the two spouses' gross annual incomes, multiply by 1.5% (low range) to 2% (high range), and multiply again by the number of years of cohabitation. The maximum amount is capped at 50% of the gross income difference. Duration ranges from 0.5 to 1 year per year of marriage, with support becoming indefinite (subject to review) after 20 years of marriage or when the marriage years plus the recipient's age at separation equals 65.
For example, if Spouse A earns CAD $120,000 and Spouse B earns CAD $40,000 after a 15-year marriage in Quebec, the income difference is CAD $80,000. The low range equals $80,000 multiplied by 1.5% multiplied by 15 years, producing CAD $18,000 per year (CAD $1,500 per month). The high range equals $80,000 multiplied by 2% multiplied by 15 years, producing CAD $24,000 per year (CAD $2,000 per month). Duration would range from 7.5 to 15 years under the SSAG framework.
With Child Support Formula
The with child support formula is more complex because it accounts for the paying spouse's child support obligation before calculating spousal support. Quebec's version of this formula adjusts for the province's unique child support model under the Quebec Child Support Determination Model (Regulation respecting the determination of child support payments, CQLR c. C-25.01, r. 12) and for Quebec's more generous child benefits, including the Family Allowance. The SSAG with child support formula shares the spouses' combined individual net disposable income (INDI) so that the lower-income spouse receives between 40% and 46% of the combined INDI.
What Factors Do Quebec Courts Consider When Setting Spousal Support?
Quebec courts consider the needs and means of both spouses, the length of the marriage, each spouse's age and health, and the time needed for the recipient to achieve financial autonomy, as required by CCQ art. 587. The court examines all sources of income, assets, debts, employability, and whether one spouse sacrificed career advancement during the marriage. Quebec judges have broad discretion and are not restricted to a fixed formula.
Under CCQ art. 587.1, the court specifically considers the assets of each spouse, including any rights accumulated under a pension plan. The court also evaluates the standard of living during the marriage, the distribution of roles during the relationship, and whether one spouse assumed a disproportionate share of domestic responsibilities. Quebec courts may consider the Family Patrimony division under CCQ arts. 414-426 when assessing overall financial circumstances, because a substantial patrimony equalization payment could reduce the need for ongoing spousal support.
| Factor | How It Affects Support |
|---|---|
| Income Disparity | Greater gap increases support amount |
| Marriage Length | Longer marriage increases duration and amount |
| Age and Health | Older or less healthy recipient may receive more |
| Parenting Responsibilities | Primary parent may receive higher support |
| Career Sacrifice | Spouse who left workforce receives compensatory support |
| Self-Sufficiency Timeline | Court sets duration to achieve financial autonomy |
| Family Patrimony Division | Large equalization payment may reduce support need |
| Standard of Living | Court considers lifestyle during marriage |
How Is Spousal Support Different From Family Patrimony Division in Quebec?
Spousal support and family patrimony are two separate legal mechanisms in Quebec divorce. Family patrimony under CCQ arts. 414-426 requires equal division of specific property categories (family residences, furniture, vehicles, and pension rights accrued during marriage), while spousal support under CCQ art. 585 provides ongoing or lump-sum payments based on need and ability to pay. Both may apply simultaneously in the same divorce proceeding.
Family patrimony division is mandatory and applies to all married and civil-union couples in Quebec regardless of their matrimonial regime. The division is based on property value, not ownership. Spousal support, by contrast, is discretionary and based on the circumstances of each case. A spouse who receives a large patrimony equalization payment may still qualify for spousal support if the payment does not address ongoing income disparity. Conversely, a generous patrimony settlement may reduce or eliminate the need for periodic support payments. Quebec courts assess both mechanisms together when determining the overall financial outcome of a divorce.
Can Common-Law Partners Claim Spousal Support in Quebec?
Common-law (de facto) partners in Quebec cannot claim spousal support under provincial law. The Supreme Court of Canada confirmed this position in Quebec (Attorney General) v. A, 2013 SCC 5, ruling that CCQ art. 585 does not violate the Canadian Charter of Rights and Freedoms by excluding de facto spouses from alimentary obligations. Quebec remains the only Canadian province where common-law partners have no statutory right to spousal support.
This exclusion means that approximately 38% of Quebec couples living in de facto unions (according to Statistics Canada, 2021 Census) have no access to spousal support upon separation unless they have a cohabitation agreement that explicitly provides for it. Common-law partners in Quebec can protect themselves by entering a written cohabitation contract ("contrat de vie commune") that specifies support obligations. Without such a contract, a de facto spouse who sacrificed career opportunities during a 20-year relationship has no legal claim to support from the higher-earning partner under Quebec law.
How Much Does It Cost to File for Divorce in Quebec?
Filing for divorce in Quebec costs CAD $108 for a joint (uncontested) application or CAD $325 for a contested application at the Superior Court, plus a mandatory CAD $10 Central Registry fee payable to Justice Canada. These fees are indexed annually on January 1 under the Tariff of Court Costs. The total cost of a Quebec divorce ranges from approximately CAD $1,750 for an uncontested divorce to CAD $13,638 or more for a contested proceeding, based on 2020 median cost data.
Quebec divorce attorneys charge between CAD $150 and CAD $500 per hour, with a median rate of approximately CAD $375 per hour. Mediation services, which are partially subsidized by the Quebec government for the first 5 hours of sessions, can significantly reduce costs. Legal aid is available through the Commission des services juridiques for individuals whose income falls below provincial thresholds. As of January 2026, a single person in Quebec qualifies for legal aid if their annual income is below approximately CAD $26,000. Verify current fees with your local Superior Court clerk.
What Are the Residency Requirements for Divorce in Quebec?
At least one spouse must have been ordinarily resident in Quebec for a minimum of 1 year immediately before filing for divorce, as required by Divorce Act, s. 3(1). The application must be filed at the Superior Court in the judicial district where the spouses last had their joint residence or, if they no longer live together, where either spouse currently resides. There is no additional municipal or district-level residency requirement beyond the 1-year provincial threshold.
The 1-year residency requirement applies to either spouse, not necessarily the applicant. If one spouse has lived in Quebec for 14 months while the other spouse lives in Ontario, the Quebec-resident spouse can file in Quebec. The court where the application is first filed generally retains jurisdiction under Divorce Act, s. 3(1). For couples where both spouses live in different provinces, the spouse who files first establishes the jurisdiction for the divorce proceeding.
How Long Does Spousal Support Last in Quebec?
Spousal support duration in Quebec depends on the length of the marriage and whether the SSAG guidelines are applied. Under the SSAG without child support formula, duration ranges from 0.5 to 1 year of support for each year of marriage. Support becomes indefinite (subject to review, not necessarily permanent) when the marriage lasted 20 years or more, or when the years of marriage plus the recipient's age at separation equals 65 or more (the "rule of 65").
Quebec courts emphasize the goal of self-sufficiency under CCQ art. 587, which directs judges to consider the time needed for the recipient to "acquire sufficient autonomy." In shorter marriages of 5 years or less without children, Quebec courts frequently award support for 1 to 3 years as a transitional measure. In marriages lasting 10 to 19 years, support typically ranges from 5 to 15 years. For marriages of 20 years or longer, Quebec courts often order indefinite support subject to a future review or material change in circumstances, consistent with the SSAG "rule of 65" framework.
| Marriage Length | SSAG Duration Range | Typical Quebec Court Approach |
|---|---|---|
| Under 5 years | 0.5-5 years | Transitional, 1-3 years |
| 5-10 years | 2.5-10 years | Medium-term, review date set |
| 10-19 years | 5-19 years | Longer-term, possible review |
| 20+ years | Indefinite (review) | Indefinite, subject to material change |
| Rule of 65 met | Indefinite (review) | Indefinite, subject to material change |
Can Spousal Support Be Modified After Divorce in Quebec?
Spousal support orders in Quebec can be modified when there is a material change in circumstances, as permitted by Divorce Act, s. 17 for divorce judgments or CCQ art. 594 for provincial orders. Common qualifying changes include job loss, retirement, significant income increase or decrease, serious illness, or the recipient achieving self-sufficiency. The party seeking modification must file a motion at the Quebec Superior Court demonstrating the change.
The threshold for modification requires that the change be significant, unforeseen at the time of the original order, and ongoing rather than temporary. A temporary 3-month layoff would generally not justify a modification, while a permanent disability reducing earning capacity by 40% or more would likely qualify. Quebec courts may increase, decrease, suspend, or terminate support based on the changed circumstances. Under CCQ art. 596, the court may also convert periodic support payments to a lump sum when circumstances warrant, such as when the paying spouse has assets but unreliable income.
How Do Quebec Courts Handle Spousal Support and Tax Implications?
Periodic spousal support payments in Quebec are tax-deductible for the paying spouse and taxable income for the receiving spouse under the federal Income Tax Act and Quebec's Taxation Act. This tax treatment means that the net cost to the payor is lower than the gross payment, while the recipient receives less after taxes. An alimony calculator for Quebec should account for these tax effects when estimating the real financial impact of support.
Lump-sum spousal support payments receive different tax treatment in Quebec. A lump sum is generally not deductible by the payor and not taxable to the recipient, making it a fundamentally different financial arrangement. The SSAG formulas calculate ranges based on gross income, so the actual after-tax impact requires additional calculation. For a payor in Quebec earning CAD $150,000 (combined federal and provincial marginal tax rate of approximately 48.4%), a monthly spousal support payment of CAD $2,000 costs approximately CAD $1,032 after the tax deduction. The recipient receiving CAD $2,000 monthly with CAD $40,000 in other income (approximate 32% combined marginal rate) retains approximately CAD $1,360 after taxes.
