Back child support in Nova Scotia refers to unpaid support payments, called arrears, that a payor owes under a court order or registered agreement. As of March 2026, the Nova Scotia Maintenance Enforcement Program (MEP) holds approximately $52.7 million in outstanding support obligations and can garnish up to 50% of wages, suspend driver's licences, intercept tax refunds, and revoke passports to collect this debt. Arrears do not expire, accumulate interest, and remain collectible even after a child becomes an adult.

What Is Back Child Support in Nova Scotia?
Back child support in Nova Scotia is the total unpaid amount, known as arrears, that a payor failed to pay under a maintenance order or court-registered agreement. Under the N.S. Maintenance Enforcement Act § 2, arrears include every missed or partial payment, and the Director of Maintenance Enforcement is presumed correct as to the amount owing. There is no statutory limit on how far back these debts reach.
Arrears arise whenever a payor stops paying, pays late, or pays less than the ordered amount. In Nova Scotia, child support amounts are set under the N.S. Parenting and Support Act § 10 and the Provincial Child Support Guidelines, which tie the payment to the payor's income. When a payor's actual income exceeds what was declared, the difference can become past due child support, creating a child support debt that builds over months or years. Nova Scotia currently records roughly $52.7 million in such outstanding obligations across thousands of cases, down from $63 million in 2018 after enforcement increased 30%.
How the Maintenance Enforcement Program Collects Arrears
The Maintenance Enforcement Program collects back child support in Nova Scotia by garnishing income, seizing assets, and suspending licences under the N.S. Maintenance Enforcement Act § 13. MEP can garnish up to 50% of wages, deduct 100% of income tax refunds and lottery winnings, and intercept Canada Pension Plan and Employment Insurance benefits. The program operates as a neutral intermediary so parents never collect directly from each other.
When a support order is issued anywhere in Nova Scotia, a copy is automatically sent to MEP for registration. Once a payor falls into default, MEP enforcement officers can move quickly. They may issue an Attachment Order requiring an employer to deduct support directly from the paycheque under the N.S. Maintenance Enforcement Act § 15. For arrears specifically, a garnishment on wages is usually a maximum of 25% of the payor's gross (before-tax) income, in addition to the regular monthly payment. MEP can also seize bank accounts, force the seizure and sale of real or personal property, and demand financial disclosure from the payor and third parties. In 2026, MEP shares data with the Canada Revenue Agency to locate income and assets that payors attempt to hide.
Driver's Licence Suspension and Passport Revocation
MEP can suspend a payor's driver's licence and request federal passport denial when child support arrears accumulate in Nova Scotia. Under the N.S. Maintenance Enforcement Act § 35, the Director may ask the Registrar of Motor Vehicles to suspend or revoke the payor's driver's licence, owner's permit, or vehicle registration. Federal denial of passport renewal is available through the federal Family Orders and Agreements Enforcement Assistance Act.
These measures are among the most effective enforcement tools because they create immediate, practical consequences. A payor who cannot legally drive often cannot work, which incentivizes payment of the past due child support. Passport denial prevents a payor from leaving the country or renewing travel documents until they address the child support debt. MEP applies these remedies once a payor reaches "persistent arrears," defined by regulation as missed full payments in any three payment periods or accumulated arrears of $3,000 or more. After repeated, willful non-compliance, the N.S. Maintenance Enforcement Act § 51 allows a court to order imprisonment of up to 15 days per missed payment, though this is a last resort reserved for payors who can pay but refuse.
Do Child Support Arrears Expire in Nova Scotia?
Child support arrears do not expire in Nova Scotia and remain collectible indefinitely. Unlike most civil debts, there is no limitation period that wipes out back child support after a set number of years. Under MEP practice, arrears continue to accumulate interest and stay enforceable even after the child reaches the age of majority. The only way to reduce or cancel arrears is by court order.
This is a critical point that distinguishes child support debt from ordinary debt. The N.S. Maintenance Enforcement Act § 61A authorizes the collection of interest on arrears, which means an unpaid balance grows over time rather than shrinking. Even when MEP stops active enforcement on a closed file, the underlying debt survives because MEP only enforces orders, it cannot change them. The amount remains due and owing. Parents sometimes assume that once children grow up the obligation disappears, but identified arrears that accumulated during the children's dependency continue to exist. To correct or abolish those arrears, a parent must apply to the Supreme Court of Nova Scotia (Family Division) and meet a demanding legal test, which the Supreme Court of Canada made stricter in Colucci v Colucci (2021 SCC 24).
Retroactive Child Support: The Three-Year Rule
Retroactive child support in Nova Scotia generally reaches back up to three years from the date the recipient gave effective notice, under the rule established in DBS v SRG (2006 SCC 37). A court can order back-dated support beyond three years only where the payor engaged in blameworthy conduct, such as hiding income increases. There is no automatic right to a back-dated order, and the applicant must show a material change in circumstances.
Retroactive support differs from arrears. Arrears are amounts already ordered but unpaid, while retroactive support is a new claim to increase a past obligation that was set too low. The Supreme Court of Canada in DBS v SRG set the four governing factors: whether the recipient delayed unreasonably, the payor's blameworthy conduct, the circumstances and needs of the child, and any hardship a retroactive award would cause. To pursue retroactive support, a parent files a variation application with the Supreme Court of Nova Scotia (Family Division) under the N.S. Parenting and Support Act § 37 or Section 17 of the Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.). In Michel v Graydon (2020 SCC 24), the Court confirmed that courts can adjust historical child support even after the child is no longer dependent, because support is the right of the child.
Filing Fees and Court Costs for Variation Applications
The filing fee to vary a child support order in Nova Scotia is approximately $291.55 as of March 2026, though some commencement fees run lower. The Nova Scotia Costs and Fees Act regulations list $43.60 for issuing documents that commence a Parenting and Support Act proceeding and $66.00 for documents in a custody, access, or support action. Verify the current amount with your local Supreme Court (Family Division). As of March 2026. Verify with your local clerk.
The cost of addressing back child support depends on the route you take. To change a final child support order, you file a Notice of Variation Application (Form 59.12) with the Supreme Court (Family Division). A simple response may cost around $73.20, while a counter-application may run about $145.80. A significant cost-free alternative exists: if your registered agreement or order permits, Nova Scotia's Administrative Recalculation of Child Support Program can update support based on updated income without a court application, filing fee, or negotiation. When recalculation is unavailable, a variation application is required. Because retroactive support and arrears rescission involve complex legal factors under DBS v SRG and Colucci, legal advice is strongly recommended before filing.

How to Register Back Child Support for Enforcement
To enforce back child support in Nova Scotia, you must have a court order or court-registered separation agreement filed with MEP. You cannot use the program without a registered order that states a specific dollar amount. Once registered, MEP automatically pursues both ongoing payments and arrears. Contact MEP at (902) 424-0050 in Halifax or 1-800-357-9248 toll-free, with your case ID and PIN ready.
Registration is the gateway to all enforcement remedies. The N.S. Maintenance Enforcement Act § 9 requires that orders be filed with the court before MEP can act. MEP can only enforce orders that are clearly written and contain a specific quantum of support, which is why variable orders or orders without a stated dollar figure are difficult to enforce, especially across provincial lines. Nova Scotia maintains reciprocal maintenance enforcement agreements with every Canadian province and territory, the United States, and several other countries, so a payor who relocates does not escape the child support debt. The MEP Online portal lets recipients and payors view recent payments and any amounts in arrears. Importantly, a payor with outstanding arrears cannot withdraw from the program until the back child support is paid in full.
Can MEP Reduce or Cancel My Arrears?
MEP cannot reduce or cancel back child support in Nova Scotia, because it is an enforcement agency, not a court. Only the Supreme Court (Family Division) can rescind or vary arrears, and the legal test is strict. Following Colucci v Colucci (2021 SCC 24), a payor seeking to cancel arrears must prove a present inability to pay and that the inability will continue, supported by full financial disclosure.
This distinction frequently surprises payors who lose a job or face illness. MEP has no authority to suspend the obligation, lower the amount, or forgive the debt, even temporarily. A payor who cannot pay must apply to the court to vary the order under the N.S. Parenting and Support Act § 37, and any reduction generally applies only going forward unless the court grants retroactive relief. The Supreme Court of Canada has signaled that where the ordered amount was appropriate but arrears accumulated through non-payment, payors are unlikely to succeed in cancelling that debt. The practical lesson is that payors who experience an income drop should apply to vary immediately rather than waiting, because delay both increases the child support debt and weakens the legal case for relief.
