Key takeaways
  • The Family Responsibility Office cannot reduce or forgive arrears itself; it enforces the order as written.
  • Arrears can be reduced by a court varying or rescinding the order, or by the recipient's written agreement filed with FRO.
  • Only a judge can change the amount of support in an order.
  • If you are falling behind, contacting FRO right away and acting on notices matters, because enforcement steps carry deadlines.

Falling behind on child support can feel overwhelming, especially when the balance keeps growing. Many payors ask whether arrears can simply be wiped out. The honest answer is that sometimes they can be reduced, but not by asking the enforcement office to forgive them.

This article explains who can reduce arrears, how courts approach it, what the Family Responsibility Office (FRO) does and does not do, and what to do if you have a notice in hand. It is general information, not legal advice.

What FRO can and cannot do

FRO cannot reduce or forgive arrears. It enforces the order as written. Only a judge can change the amount of support in an order, and FRO cannot do it.

What FRO does offer is a way to deal with arrears you cannot pay in a lump sum. It asks you to contact it right away if you fall behind, and it offers a voluntary arrears payment schedule, which involves a proposal form and a financial statement.

Two routes to reducing arrears

Reducing or cancelling arrears requires either a court to vary or rescind the order, or a written agreement from the recipient filed with FRO. The recipient can also ask FRO in writing to discontinue enforcement. What a recipient can do privately beyond that process depends on the facts, so get advice before relying on an informal arrangement.

RouteWhat it involves
CourtA judge varies, rescinds or suspends the order. Under the Divorce Act this can be done retroactively or prospectively.
Recipient's written agreementThe recipient agrees in writing and the agreement is filed with FRO.
Recipient asks FRO to stopThe recipient asks FRO in writing to discontinue enforcement.
FRO payment scheduleDoes not reduce the debt, but sets a voluntary schedule to pay it.

How courts approach reducing past support

Before a court varies child support under the Divorce Act, it must find a change of circumstances as provided for in the applicable guidelines. For a table-based order, a change in circumstances is any change that would result in a different child support order.

For retroactive decreases or rescinding arrears under the Divorce Act, the Supreme Court of Canada set out a framework in Colucci v. Colucci, 2021 SCC 24. The payor must show a past change in circumstances. The court's discretion is guided by a presumption in favour of decreasing support retroactively to the date of effective notice to the recipient, capped at three years before formal notice. Bad faith and lack of disclosure weigh against the payor.

That case concerns the Divorce Act. Orders made under other laws may be approached differently, so whether it applies to your order is worth confirming with a lawyer.

How timing affects your own situation depends on your order and your facts, so it is worth confirming with a lawyer. Being open about your finances matters too, since lack of disclosure counts against the payor.

What enforcement can look like while arrears remain

Until the order is changed or the arrears are dealt with, FRO can use a range of enforcement tools.

A $400 administrative fee may be charged when FRO takes enforcement action.

Interest and what to do next

Interest can be part of the arrears. It is claimable if the order states an interest rate, and if the order has no interest provision it may be claimed under the Courts of Justice Act and Family Law Rules for orders made on or after certain dates. FRO takes enforcement action only on interest that accrued because the payor did not comply with the order. Which interest rate applies to your arrears depends on your order, so it is worth confirming with a lawyer.

Frequently asked questions

Can FRO write off my child support arrears?

No. FRO cannot reduce or forgive arrears and enforces the order as written. Reducing them takes a court variation or rescission, or a written agreement from the recipient filed with FRO.

Can the recipient forgive the arrears?

A recipient can give a written agreement that is filed with FRO, and can ask FRO in writing to discontinue enforcement. Beyond that process, it depends on the facts and is worth confirming with a lawyer.

How far back can a court reduce support?

Under the Divorce Act framework, the presumption favours decreasing support back to the date of effective notice to the recipient, capped at three years before formal notice. Bad faith and lack of disclosure weigh against the payor.

What should I do if I have just lost my job?

Contact FRO right away and ask about a voluntary payment schedule. Because only a judge can change the amount of support, speak to a lawyer promptly about applying to change the order.
