Child Support & The Divorce Act
Federal Laws for Married Couples
Filing for divorce triggers federal jurisdiction. Understand how the Divorce Act (Canada) defines a 'Child of the Marriage' and your financial obligations.
Legal Review: This legislative guide was reviewed by Deepa Tailor, Senior Family Lawyer, to ensure compliance with the Divorce Act (Canada) and recent 2021 amendments regarding support and parenting (2026).
When Does the Divorce Act Apply?
The Divorce Act is a federal law that applies only to married couples who have filed an Application for Divorce. If you are Common Law, or Married but separated without filing for divorce, you fall under the provincial Family Law Act. The distinction matters because the Divorce Act has broader definitions for who qualifies for support, particularly for adult children with disabilities or those attending university.
The Language of Federal Law
'Child of the Marriage'
The core definition. Any child under the age of majority (18), OR over 18 but unable to withdraw from parental charge due to illness, disability, or other cause (education).
'In Loco Parentis'
Step-parents under the Divorce Act are those who 'stand in the place of a parent.' The Act allows judges to order support from step-parents, usually secondary to biological parents.
'Corollary Relief'
Support orders made under the Divorce Act are called 'Corollary Relief Orders.' They are nationwide orders, enforceable in any province without complex registration.
'Maximum Contact'
While primarily about parenting time, this principle influences support. The Act encourages maximum time with both parents, which often leads to 'Set-Off' support calculations.
The 'Adult Child' Difference
Why some parents rush to file for Divorce while others wait.
Family Law Act (Provincial)
Stricter Limit.
Historically, provincial law ended support strictly at age 18 or when school ended. It was harder to get support for a 25-year-old disabled child who wasn't in school.
Divorce Act (Federal)
Broader Scope.
Section 2(1) allows support for adult children due to 'illness, disability, or other cause.' This broad wording is often used to secure lifelong support for severely disabled adult children of divorced parents.
Securing a Federal Support Order
The Application for Divorce
We file Form 8A. This claims the divorce and Corollary Relief (Child Support). This officially triggers the federal Divorce Act rules.
Financial Disclosure
Required under Section 21 of the Guidelines. Even if you agree on the amount, the judge cannot sign the Divorce Order without seeing proof of income.
The Divorce Order
The judge signs the final Divorce Order. This document contains the permanent child support terms.
Inter-Provincial Enforcement
Because it is a federal order, if the payor moves to Alberta or BC, the order follows them automatically. It is easier to enforce across borders than a provincial order.
