Key takeaways
  • A support order can be varied by the court even after it has been filed with the Maintenance Enforcement Program, and apart from a yearly recalculation of child support for orders in the Child Support Recalculation Program, the amount does not change until the court makes a new order.
  • The Child Support Recalculation Program works going forward only and does not award or reduce arrears.
  • If you or the other parent live outside Alberta, the Maintenance Enforcement Program can still help, and payors outside Alberta pay through the enforcement program where they live.

Unpaid support is stressful from both sides. A recipient may be counting on money that has stopped arriving. A payor may have fallen behind after a job loss or a change in family life and may not know what comes next.

In Alberta, the Maintenance Enforcement Program (MEP) is the body that helps with support payments and collection. This article explains where MEP fits, what the court can do about arrears, and how to ask for a change. The specific collection tools MEP uses on a given file, and how enrolment or withdrawal works, depend on your file, so confirm those details with MEP or a lawyer.

This article covers the law of Alberta.

Where the Maintenance Enforcement Program fits

A support order is a court order. A court can vary, suspend or terminate it under the Alberta Family Law Act, and where the parties were married and divorced, either or both former spouses can apply to vary, rescind or suspend a support order under the Divorce Act. That power continues even though the order has been filed, for example with the Maintenance Enforcement Program.

In plain terms, filing an order with MEP changes how payments are tracked and collected. It does not freeze the order in place. If your income, expenses or family situation has changed, you still have a route to ask the court for a change, covered below.

What happens to arrears when circumstances change

Apart from a yearly recalculation of child support under the Child Support Recalculation Program, the support amount does not change until the court has made an order. That matters for payors. If your income drops and you stop paying, the unpaid amounts can keep building under the existing order. Waiting to apply is the risk.

A payor who wants to reduce or cancel arrears, where the parents are divorced or a divorce was started, uses the Application to Reduce or Cancel Arrears. Whether the court will agree depends on the facts, so this is worth discussing with a lawyer before you file.

The Child Support Recalculation Program is a separate service. It applies only going forward and does not award or reduce arrears, provide retroactive support, or help parents get a new order.

Asking the court to change a support order

For child support under the Family Law Act, the court must be satisfied of a change of circumstances, or that evidence of a substantial nature that was not available at the previous hearing has become available. Alberta.ca lists examples of significant changes: the number of dependent children, a long-term change in employment income, special or extraordinary expenses, and travel or access costs.

Spousal support, or support between adult interdependent partners, uses a different test: a change in the condition, means, needs or other circumstances of either person.

The recipient applies for an increase and the payor applies for a decrease. The forms depend on your situation:

File at the court and location where you have already been to court with the other party or started an action. If neither applies, file at any court in Alberta. If you do not attend, the judge may make an order in your absence.

If someone lives outside Alberta

MEP can facilitate support payments if the payor or recipient lives outside Alberta, under the Interjurisdictional Support Orders Act. Reciprocal registration agreements cover all Canadian provinces and territories, all American states and territories, and over 20 other countries.

Payors living outside Alberta pay the enforcement program in their own jurisdiction, not the recipient directly, to avoid late penalties and double payment. To change an order or get file updates, contact the enforcement program where you live.

Orders made under the Divorce Act about support have legal effect throughout Canada. They may be registered in a court in another province and enforced as that court's own order, but a court may vary them only in accordance with the Act.

Recalculation, objections and contempt

If your order is in the Child Support Recalculation Program, each parent pays a $77 service fee for each recalculation that changes their child support amount, even if they disagree with the decision. Parents in MEP have it applied to their MEP file automatically.

A parent has 30 days after receiving a recalculation decision to object. To object, apply to court to vary, suspend or terminate the order and send the program a Notice of Objection to Recalculation Decision with the filed application and affidavit.

Separately, the court can deal with a person who does not follow an order through civil contempt. A judge may declare civil contempt where a person, without reasonable excuse, does something listed, such as not complying with an order. Contempt is a serious step, so get legal advice before choosing it.

What to do next

Whether you are owed support or owe it, start by getting clear on the numbers and the order itself. Then decide whether you need a change, a payment arrangement or enforcement help.

Frequently asked questions

Can I change my support order if it is already with MEP?

Yes. The court may vary, suspend or terminate a support order even though it has been filed, for example with the Maintenance Enforcement Program. Apart from a yearly recalculation of child support for orders in the Child Support Recalculation Program, which uses both parents' current income tax information, the amount stays the same until the court makes a new order.

Will the Recalculation Program wipe out my arrears?

No. Recalculation applies only going forward. It does not award or reduce arrears or provide retroactive support.

What if the other parent lives in another province or country?

MEP can facilitate payments through reciprocal registration agreements with all Canadian provinces and territories, all American states and territories, and over 20 other countries. A payor outside Alberta pays the enforcement program where they live, and should contact it to change an order or get file updates.

How do I withdraw from MEP?

The rules for leaving MEP depend on your file, so confirm them with MEP or a lawyer. Withdrawal from the Child Support Recalculation Program is a separate process, with forms due 60 days before the order's anniversary date.
