Key takeaways
  • A written child support agreement that is filed in court is enforceable as if it were a court order.
  • A private agreement must be filed with the court registry before it can be enrolled for enforcement with the BC Family Maintenance Agency.
  • Support is the child's legal right, so parents cannot agree that the other parent does not have to pay it.

When parents separate, one of the first questions is how to put child support in writing. A court order, a written agreement filed in court and a private agreement can all record the same amount, but they work differently when payments stop or circumstances change.

This article explains how each option generally works in British Columbia, what happens if support is late, and how each can be changed. Details matter here, so a lawyer can confirm how this applies to your situation.

This article covers the law of British Columbia.

Three ways child support can be set

A court order is made by a judge. Under the Family Law Act, child support orders must follow the child support guidelines. Under the Divorce Act, a court making a child support order must also act in accordance with the applicable guidelines.

A written agreement is one the parents sign themselves. It can be filed in the court registry or kept private, and that choice affects how it can be enforced.

What the law says about agreements

Support belongs to the child. BC government guidance says a parent cannot make an agreement saying the other parent does not have to pay child support.

Under the Family Law Act, a child support agreement is binding only if it was made after separation or when the parties are about to separate. On application, the court may set aside or replace all or part of it with an order if it would order something different applying the section 150 factors.

An agreement can still differ from the guideline amount. The Family Law Act lets a court depart from the guidelines if the parties consent or have an agreement and reasonable arrangements exist for the child's support, and arrangements are not unreasonable merely because they differ from the guideline amount. The court must give reasons when it departs.

Private agreement, not filedMust first be filed with the court registry to be enrolled with BCFMAA court may set aside or replace all or part of it

Enrolment matters because it gives you an enforcement body. Under the Family Maintenance Enforcement Act, a filed maintenance order can be enforced by the director, who must enforce it where necessary and practicable. The director can serve a notice of attachment on anyone who owes money to the person who owes support. Where arrears total $3,000 or more, the director may act under s. 29.1, and ICBC must then cancel the debtor's driver's licence and not issue or renew one for the applicable period. The director must have ICBC disregard the notice in specified cases, such as a material error or a satisfactory payment arrangement.

Support and parenting time are separate issues. A paying parent cannot withhold support over parenting time problems, and a parent cannot refuse parenting time because support is behind.

Changing an order or agreement later

Support does not end automatically in an existing order. A court may change, suspend or terminate a child support order on application, prospectively or retroactively. Before doing so, the court must be satisfied of a change in circumstances under the guidelines, substantial new evidence unavailable at the earlier hearing, or evidence of a lack of financial disclosure discovered after the last order.

A court application is not always needed. The BC Child Support Recalculation Service reviews eligible orders and agreements each year, adjusting support using the paying parent's income tax information and the Guidelines tables.

What to do next

Frequently asked questions

Is a private child support agreement enforceable in BC?

It may be binding if it was made after separation or when you are about to separate, but a court can set aside or replace it. To get help from BCFMA, the agreement must first be filed with the court registry. A lawyer can tell you how this applies to your agreement.

What does filing a written agreement in court do?

A written child support agreement filed in court is enforceable as if it were a court order. It can then be enrolled with BCFMA.

Can we agree that no child support is paid?

No. BC guidance says a parent cannot make an agreement saying the other parent does not have to pay child support, because support is the child's legal right.

How do I enrol an order with BCFMA?

You can enrol online, call 1-866-557-2427 to have an enrolment package mailed to you, download that package, or pick one up at a provincial courthouse or ServiceBC. BCFMA sends a Notice of Filing when enrolment is complete.
