If a parent is not paying child support, you can take a few steps: Register your child support order or agreement with the maintenance enforcement program or office in your province. For example, Alberta has the Maintenance Enforcement Program. Go to court and ask the judge to order the other parent pay you child support arrears. Child support arrears are overdue child support payments. When child support is in arrears, a judge can: order the payor to pay the full amount in arrears change the amount in arrears, or cancel the amount in arrears. Last updated: March 2021
