Child Support Recalculation After Divorce in BC

Child Support Doesn't Stay Fixed

The amount set in your divorce order or separation agreement was calculated from one snapshot of income. Incomes change. Jobs change. Kids grow up and their needs shift. Canadian family law expects child support to keep pace — and BC has a specific mechanism to make that happen without going back to court every time.

Under both the Federal Child Support Guidelines and BC's Family Law Act, child support is based on the payer's gross annual income and the number of children. When that income changes materially — through a raise, job loss, retirement, or new employment — the support amount should be updated to reflect the current Federal Child Support Guidelines table amounts.

The BC Child Support Recalculation Service

BC operates a Child Support Recalculation Service (CSRS) that can update child support amounts administratively, without either parent filing a court application. The service is free and available to parents whose orders meet certain criteria:

• The order must have been made under the Divorce Act or BC's Family Law Act
• The order must use the Federal Child Support Guidelines table amounts (not a fixed dollar amount negotiated outside the tables)
• Both parents must reside in BC (or one parent in BC with the order filed in a BC court)

How it works: Each year, the CSRS requests updated income information from both parents. Using the current tax return (specifically the CRA Notice of Assessment), the service recalculates the table amount based on the payer's most recent income. If the recalculated amount differs from the current order by at least $5 per month, the CSRS issues a new amount that takes effect 31 days after both parties are notified — unless either parent objects and files a court application within that window.

To enrol, contact the CSRS through the BC Family Justice Services Division. Enrolment is voluntary, but courts can order mandatory participation as part of a custody or support order.

When You Need to Go Back to Court

The recalculation service handles straightforward table-amount adjustments. But some situations require a formal court application to vary the support order:

Shared or split custody changes. If the parenting arrangement shifts from primary custody to shared custody (each parent having the child at least 40% of the time), the support calculation changes from a straight table lookup to a set-off calculation comparing both parents' incomes. The CSRS can't do this — it requires a variation application.

Section 7 "special or extraordinary" expenses. Childcare, medical expenses not covered by insurance, extracurricular activities, and post-secondary education costs are divided in proportion to each parent's income, on top of the base table amount. Changes to these expenses require agreement or a court order.

A child turns 19. In BC, child support generally continues past 18 if the child is still dependent — enrolled in full-time education, for example. But the guidelines treat children over 19 differently, and the amount may need adjustment or termination.

The payer's income exceeds $150,000. Above this threshold, the Federal Child Support Guidelines table provides a base amount plus a discretionary percentage. Courts have latitude in how they apply the excess, and the CSRS doesn't have jurisdiction over the discretionary portion.

Income Disclosure Is Mandatory

Both parents have an ongoing obligation to disclose their income when requested. Under the Federal Child Support Guidelines, the payer must provide:

• Their most recent income tax return
• Their most recent CRA Notice of Assessment and Reassessment
• Current pay stubs if employed, or financial statements if self-employed

The recipient can request this information annually, and the payer has 30 days to comply. Failure to disclose income can result in the court imputing income — essentially estimating your earnings based on available evidence, which often results in a higher support amount than actual income would produce.

If you're self-employed, income disclosure is more complex. Courts look beyond the tax return to the corporation's financial statements, personal benefits drawn from the business, and any income-splitting arrangements.

Enforcement When Payments Fall Behind

When child support goes unpaid, the BC Family Maintenance Enforcement Program (FMEP) has the same enforcement tools available as for spousal support — wage garnishment, bank account seizure, driver's licence suspension, passport hold, property liens, and credit bureau reporting. Unlike spousal support, child support arrears survive bankruptcy and accumulate post-judgment interest.

If you're the receiving parent and support payments have stopped or fallen behind, enrol in FMEP immediately. Enrolment is free. FMEP can also help locate a payer who has moved or changed employment.

Keep Your Order Current

An outdated support order creates problems for both sides. The payer may be overpaying relative to their current income and accumulating resentment. The recipient may be underpaid while the payer's income has grown. Either way, the fix is the same — update the order to match current circumstances.

The BC After-Divorce Checklist includes the income disclosure timelines, FMEP enrolment steps, and a tracking worksheet for support payments — part of the full post-divorce administrative sequence.
