What If My Ex Won't Pay Alimony in Quebec? 2026 Enforcement Guide

When your ex-spouse refuses to pay court-ordered alimony in Quebec, you have powerful enforcement mechanisms at your disposal. Quebec operates Canada's most robust government-run support collection system through Revenu Quebec, which automatically deducts payments from the payor's income under the Act to facilitate the payment of support (CQLR c. P-2.2). The collection rate for domestic enforcement in Quebec exceeds 85%, and persistent non-payers face wage garnishment up to 50% of earnings, asset seizure by bailiff, legal hypothec registration against property, passport suspension, and contempt of court penalties including fines up to CAD $10,000 or imprisonment up to one year under Code of Civil Procedure, art. 62.

Key Facts: Quebec Alimony Enforcement

Registering with Revenu Quebec's Support-Payment Collection Program

Revenu Quebec's Support-Payment Collection Program provides free, automatic enforcement of spousal support orders without requiring individual collection efforts from the recipient spouse. Once your Quebec court judgment grants spousal support, Revenu Quebec automatically administers collection by deducting payments directly from the payor's income, indexing the support amount annually for inflation, and remitting payments to you on a consistent schedule. The program collected over CAD $700 million in support payments in 2024, demonstrating its effectiveness as the primary enforcement mechanism for alimony enforcement in Quebec.

To register with the program, submit your court order granting spousal support to Revenu Quebec's Support-Payment Collection office. Registration is automatic for most Quebec divorce judgments issued after 1995. If you have an older order or one from outside Quebec, you must provide certified copies of the judgment, both parties' social insurance numbers and addresses, and employment information for the payor spouse if known. Processing typically takes 30-45 days after registration.

The program handles collection at no cost to you, eliminating the need to repeatedly pursue your ex-spouse through the courts. Even self-employed payors cannot easily evade collection, as Revenu Quebec has authority to garnish bank accounts, seize assets, and register legal hypothecs against property when voluntary payments cease.

Wage Garnishment and Source Deductions

Wage garnishment represents the most effective enforcement tool for collecting unpaid alimony from employed ex-spouses in Quebec. Under the Act to facilitate the payment of support (CQLR c. P-2.2), Revenu Quebec can garnish up to 50% of a support debtor's net earnings, compared to only 30% for ordinary debts. This elevated garnishment rate reflects Quebec's policy priority of ensuring support obligations are paid.

When Revenu Quebec issues a deduction notice to an employer, the employer becomes legally obligated to withhold the specified amount and remit it directly to Revenu Quebec for your benefit. Employers who fail to comply with deduction notices become jointly liable with the payor for the support owed. This joint liability provision ensures employers take garnishment orders seriously and do not assist payors in evading their obligations.

Garnishment exemptions protect a portion of the debtor's income to cover basic living expenses. As of April 2024, the weekly exemption amounts are approximately CAD $217 for a single person, with additional amounts for dependents. Revenu Quebec publishes updated garnishment exemption tables each year. The seizable portion is calculated after accounting for these exemptions, ensuring the payor retains sufficient income for basic necessities while still satisfying support obligations.

For self-employed payors or those with irregular income, Revenu Quebec can garnish amounts owed by clients, seize business receivables, or attach funds held in business bank accounts. The agency's broad enforcement powers make it difficult for determined non-payers to shield income from collection.

Seizure of Assets by Bailiff

When wage garnishment proves insufficient or the payor is self-employed with limited garnishable income, you can pursue seizure of assets through a Quebec bailiff. This process, known as forced execution, allows collection of unpaid alimony from the debtor's property including vehicles, furniture, bank accounts, liquid cash, investment accounts, and other valuable assets. Seizure by bailiff often produces faster results than contempt proceedings and may be the preferred remedy when the payor has assets but claims inability to pay.

To initiate seizure, you need a final judgment ordering support that remains unpaid. Your attorney files a motion for forced execution at the Superior Court, and once authorized, a bailiff executes the seizure. The bailiff physically locates and seizes assets, which are then sold at judicial auction with proceeds applied to your support arrears. Bank account seizures are particularly effective, as they capture funds immediately without requiring physical sale of property.

Seizure enjoys priority over ordinary creditors for support arrears. Under CQLR c. P-2.2, when the Minister acts as claimant, other creditors' claims are subordinate to support obligations. This super-priority status means your unpaid alimony takes precedence over most other debts your ex-spouse may owe, increasing the likelihood of successful collection.

The costs of seizure proceedings, including bailiff fees and court costs, are typically added to the amount owed by the debtor. This means pursuing enforcement does not further deplete your already unpaid support—the payor bears the enforcement costs as well as the arrears.

Legal Hypothec on Property

Registering a legal hypothec against your ex-spouse's immovable property provides powerful security for unpaid support arrears. Under Quebec civil law, a hypothec functions similarly to a mortgage lien, creating a registered charge against real estate that must be satisfied before the property can be sold or refinanced. Once registered, the hypothec follows the property into whosever hands it may be, as stated in CCQ art. 2660.

To register a hypothec for support arrears, you must obtain a court order authorizing the registration, typically granted as part of enforcement proceedings. The hypothec is then registered at the Land Registry Office (Bureau de la publicité des droits) for the district where the property is located. Registration costs approximately CAD $100-$200 plus notarial fees.

The practical effect of a registered hypothec is that your ex-spouse cannot sell or refinance the property without first paying the support arrears. This creates strong incentive for payment, particularly if the payor needs to access home equity or wishes to sell. Even if the payor attempts to sell, the purchaser's notary will discover the hypothec during title searches and require its discharge before closing, ensuring you receive payment.

Hypotheques for support arrears take priority over most subsequent creditors and even some prior creditors. This super-priority protects your claim against other debts the payor may incur. The hypothec remains in force until the support arrears are paid in full or the court orders its discharge.

Contempt of Court Proceedings

Contempt of court represents the most serious enforcement measure available when your ex-spouse deliberately refuses to comply with a support order. Under CCP art. 57-62, a person who disobeys a court order is guilty of contempt and faces significant penalties including fines up to CAD $10,000 for individuals or CAD $100,000 for corporations, community service, and imprisonment for up to one year.

Contempt proceedings are quasi-criminal in nature and require proof that the payor knowingly and willfully refused to comply with the support order despite having the ability to pay. The court must find dishonest conduct or deliberate manoeuvring to avoid payment, not mere inability to pay. This distinction is crucial: a payor who genuinely cannot afford payments due to job loss or illness would not be found in contempt, while one who hides income, transfers assets to evade payment, or simply refuses despite having resources would face contempt sanctions.

To initiate contempt proceedings, you file a motion summoning your ex-spouse to appear before the court to explain their failure to pay. Under CCP art. 59, the person charged must be served with an order specifying the day and time to appear and hear proof of the acts alleged against them. At the hearing, you present evidence of the support order, the arrears owed, and the payor's ability to pay. The payor has the opportunity to defend themselves.

If the court finds contempt was committed, the judgment must set out the facts on which the finding is based under CCP art. 61. Sanctions may be imposed immediately or in a subsequent judgment. Contempt findings can be appealed as of right, meaning no permission is needed to appeal.

Contempt should be used cautiously and only as a last resort. The proceedings are expensive, time-consuming, and can damage the relationship between separated parents if children are involved. However, for persistent, willful non-payers, contempt proceedings send a clear message that support obligations will be enforced.

Passport Suspension and Federal Enforcement

For payors who evade domestic enforcement by leaving Canada or threatening to do so, federal enforcement mechanisms provide additional leverage. Under the Family Orders and Agreements Enforcement Assistance Act, the federal government can suspend or deny passports to support debtors owing more than CAD $3,000 in arrears. This suspension remains in effect until the arrears are paid or a satisfactory payment arrangement is made.

Passport suspension is particularly effective against payors who travel frequently for work or pleasure. The inability to leave Canada creates strong incentive to resolve support arrears. To request passport suspension, Revenu Quebec must refer the case to the federal Family Responsibility Office, which then coordinates with Service Canada to flag the passport.

Other federal enforcement tools include interception of federal payments such as GST credits, income tax refunds, and Employment Insurance benefits. These funds are redirected to pay support arrears before reaching the debtor. The federal government also shares debtor information across provinces, making it difficult for non-payers to evade enforcement by relocating.

For cases involving international enforcement, Canada participates in the 2007 Hague Convention on the International Recovery of Child Support and Other Forms of Family Maintenance. This treaty provides mechanisms for enforcing support orders across member countries, with the Quebec Ministry of Justice serving as the designated Central Authority for incoming and outgoing requests.

Modification and Variation of Support Orders

If your ex-spouse claims inability to pay, they must file a formal variation application rather than simply stopping payments. Under Divorce Act, s. 17 for divorce judgments or CCQ art. 594 for provincial orders, support orders can be modified only when there is a material change in circumstances. Simply accumulating arrears and refusing to pay does not constitute grounds for variation—the payor must demonstrate a significant, unforeseen, and ongoing change such as job loss, retirement, serious illness, or the recipient achieving self-sufficiency.

Variation applications must be filed at the Superior Court of Quebec in the judicial district where the spouses reside or last resided together. The filing fee is CAD $108 as of January 2026. The applicant must provide substantial documentation including 3 years of tax returns, current pay stubs, medical records if health-related, evidence of job search efforts if claiming inability to work, and any documents proving the changed circumstances.

Courts expect parties to first attempt negotiation or mediation before litigation. 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 modification, while a permanent disability reducing earning capacity by 40% or more would likely qualify.

Until a court grants the variation, the original support order remains in full force. Arrears continue to accumulate during the variation proceedings, and the payor remains obligated to pay as ordered. Courts rarely grant retroactive reductions, meaning missed payments cannot typically be recovered even if the variation is eventually granted. This rule creates strong incentive for payors to continue paying and seek variation promptly rather than simply defaulting.

Interjurisdictional Enforcement

When your ex-spouse relocates to another province or territory, Quebec's reciprocal enforcement agreements ensure your support order remains enforceable across Canada. Quebec has reciprocal agreements with every Canadian province and territory to recognize and enforce each other's court orders for support. To enforce a Quebec support order in another province, submit your certified judgment to the appropriate enforcement agency in that jurisdiction.

Quebec is implementing the Act Respecting the Reciprocal Issue and Enforcement of Support Orders to modernize interjurisdictional enforcement. Unlike other provinces' Interjurisdictional Support Orders Acts, Quebec requires a court judgment for enforcement—separation agreements, domestic contracts, and paternity agreements alone are not enforceable without court confirmation. If you have only a separation agreement, you must first obtain a court order before seeking enforcement in another jurisdiction.

For international cases, enforcement depends on whether the payor's country has a reciprocal agreement with Quebec. The collection rate for cases involving payors outside Canada is approximately 63%, lower than domestic enforcement but still significant. The 2007 Hague Convention provides the most comprehensive framework for international enforcement among member countries.

To pursue international enforcement, contact the Ministère de la Justice du Québec, which serves as Quebec's Central Authority for international support matters. Their offices are located at Édifice Louis-Philippe-Pigeon, 1200 route de l'Église, 4e étage, Québec (Québec) G1V 4M1.

Calculating and Proving Arrears

Accurate calculation of support arrears is essential before pursuing enforcement. Arrears consist of all unpaid periodic support payments from the date of default through the current date, plus any indexation (cost-of-living increases) applied under the original order or by Revenu Quebec. Many Quebec support orders are indexed annually to the Consumer Price Index, meaning the monthly amount increases each year.

Revenu Quebec maintains detailed records of all payments made through the Support-Payment Collection Program. To obtain a statement of arrears, contact Revenu Quebec's support payment division and request an official accounting. This statement serves as proof of arrears in any enforcement proceeding. If payments were made directly between spouses rather than through Revenu Quebec, you will need to prove arrears through bank records, cancelled cheques, or other documentation.

Interest may accrue on support arrears in some circumstances, though Quebec courts have discretion in awarding interest. The legal rate of interest for civil matters in Quebec is 5% annually. Courts may award interest from the date each payment became due, significantly increasing the total amount owed in cases involving long-standing arrears.

When proving arrears in court, prepare a detailed schedule showing each payment due, the date due, any amount paid, and the running arrears balance. Cross-reference this schedule with bank records and Revenu Quebec statements. Courts expect clear, organized documentation when enforcing support obligations.

Self-Employed and Cash-Based Income Earners

Enforcing alimony against self-employed ex-spouses or those with cash-based income presents unique challenges in Quebec. These payors may underreport income, claim excessive business expenses, or simply fail to deposit earnings in accounts subject to garnishment. However, Quebec law provides several tools to address these situations.

Revenu Quebec can impute income based on lifestyle analysis when reported income does not match apparent spending. If your ex-spouse claims minimal income but lives in an expensive home, drives luxury vehicles, and takes frequent vacations, you can present this evidence to the court to argue that actual income exceeds reported amounts. Courts routinely impute income to payors who voluntarily underemploy themselves or hide income to reduce support obligations.

For business owners, you may request disclosure of business financial statements, including profit and loss statements, balance sheets, and corporate tax returns. Courts can order production of these documents if the payor refuses to provide them voluntarily. Professional valuations may be necessary for complex business interests.

Garnishment of business receivables offers another avenue for collection. Revenu Quebec can serve deduction notices on the payor's clients and customers, requiring them to remit payments directly to Revenu Quebec rather than to your ex-spouse. This approach is particularly effective for professionals, contractors, and consultants who invoice clients regularly.

Common-Law Partners and Support Enforcement

Quebec's support enforcement mechanisms apply differently to common-law (de facto) partners than to married or civil union spouses. Under CCQ art. 585, only married and civil union spouses owe each other support. Common-law partners in Quebec have no automatic entitlement to spousal support regardless of the length of their relationship, even if they have children together.

The new parental union regime created by Bill 12 (effective June 2024) provides some protections for common-law couples who become parents together, but it does not create a right to spousal support between the adult partners. The parental union regime focuses on parenting arrangements and certain property protections for the family residence, not on ongoing support obligations between partners.

If you were in a common-law relationship and your ex-partner promised support in a written agreement, that agreement may be enforceable as a contract. However, you would need to pursue enforcement through ordinary contract remedies rather than through the specialized support enforcement mechanisms available to married and civil union spouses. Consult with a Quebec family law attorney to assess the enforceability of any support promises made outside of marriage or civil union.
