Key takeaways
  • A support order does not end because the payor is in custody; it continues until a court order, a terminating event both parties agree on, or a written agreement ends it.
  • Missed support is called arrears, and the payor should contact FRO right away.
  • Only a court can change the amount, and a court can vary, rescind or suspend an order if the change test is met.
  • How a court treats income during custody depends on the facts, so legal advice early is important.

When a parent who pays child support is sentenced or detained, two questions come up fast: does support keep adding up while they are away, and can it be reduced? Recipients ask the same thing from the other side, worried about how long the money will keep coming.

This article explains the general Ontario rules that apply to any change in a payor's situation. It does not set out special jail rules, because how a court handles custody depends on the facts and should be confirmed with a lawyer.

The order keeps running until it is changed

Support ends in specific ways. FRO describes them as a court order, a terminating event that both parties agree on, or a written agreement between the payor and the recipient. Being in custody is not on that list as an automatic end point. FRO also tells payors to keep paying until it says in writing that they can stop.

The same goes for the amount. FRO says it cannot change what a payor pays, and only a court can change the amount of support. If the order says a payor owes a certain amount each month, that amount is generally still the starting point until a court says otherwise.

What happens to the missed payments

Missed support is called arrears. If a payor cannot pay because their income stops, the unpaid amounts do not simply disappear. The order has not changed, so the shortfall is generally treated as owing.

FRO says a payor who is having trouble paying should contact it right away, and that a voluntary arrears payment schedule can be worked out.

Asking a court to change the support

A court can vary, rescind or suspend a support order. Under the Guidelines, a change in circumstances that would result in a different child support order allows variation, and the Divorce Act requires the court to be satisfied that such a change has occurred before it varies a child support order.

A major change in income is the usual kind of change people point to. But courts do not simply accept the label. If a payor says income has dropped, the court looks at why. A court may impute income where a spouse is intentionally under-employed or unemployed, and it has discretion over the amount. A voluntary income drop must be explained. On the other hand, once a payor becomes unintentionally unemployed, it may not be appropriate to impute the former full salary.

How these ideas apply to a person in custody is a question that depends on the circumstances, including the length of time, any income or assets the payor still has, and the reason for the change. This is where a lawyer's advice is important.

Other points to know

QuestionGeneral answer
Does support stop automatically?No. It continues until a court order, an agreed terminating event or a written agreement ends it
Can FRO reduce the amount?No. Only a court can change the amount
What are missed payments called?Arrears; the payor should contact FRO right away
Can a court suspend an order?A court may vary, rescind or suspend a support order if the test is met

Where a payor or child would otherwise suffer undue hardship, the Guidelines let a court award a different amount, with examples such as unusually high debts or unusually high expenses of exercising parenting time. Whether any of that fits a particular situation is for a court to decide.

What to do next

Frequently asked questions

Does child support keep adding up while the payor is in jail?

FRO tells payors to keep paying until it says in writing that they can stop, and only a court can change the amount of support. Unpaid support is called arrears. A lawyer can tell you how that applies to your facts.

Can FRO lower the payments because of a jail sentence?

No. FRO says it cannot change the amount a payor pays, and only a court can. The payor can contact FRO and discuss a voluntary arrears payment schedule.

Can a court suspend child support?

A court can vary, rescind or suspend a support order, but it must be satisfied that a change in circumstances has occurred. Whether custody supports that depends on the facts.

Should the payor stop paying until the court decides?

FRO tells payors to keep paying until it says in writing that they can stop. If full payment is impossible, contact FRO right away and get legal advice.
