Does support end at 18? Understanding 'Withdrawal from Parental Control' and when you can legally stop paying child support.
Legal Review: This guide was reviewed by Deepa Tailor, Senior Family Lawyer, to ensure compliance with the Family Law Act and Divorce Act definitions of a 'Child of the Marriage' (2026).
No. Unlike the USA, there is no single document you sign to 'emancipate' a child. Emancipation is a legal finding of fact. A child is considered emancipated when they voluntarily withdraw from parental control (move out, refuse rules, become financially independent).
Crucially: Child support does NOT automatically stop at age 18 if the child is in full-time school or has a disability.
Under the Family Law Act, support typically ends at 18 unless the child is in school full-time. Under the Divorce Act, it can continue well past 18.
If a child is over 16, moves out voluntarily, and refuses to communicate or follow reasonable rules, they may be deemed to have 'withdrawn from parental control,' ending support rights.
If the child is working full-time and is financially self-sufficient, they are no longer a dependent.
If the child marries or enters a permanent common-law relationship, the parents' obligation to support them usually ends.
The most common reason support continues past 18.
If the child is enrolled in a first post-secondary degree (College/University), they usually remain a 'Child of the Marriage.' Support continues, though the child may be expected to contribute via part-time work or OSAP.
If the child takes a year off to travel or only takes 1 course, they may lose their right to support. Courts look for a diligent pursuit of education.
Request proof of school enrollment (timetables, grades) from the recipient. If they refuse to provide it, you have grounds to file.
We send a letter seeking consent to terminate support. If the other parent agrees, we sign a 'Termination Agreement.'
If the recipient refuses to stop enforcement, we file a Motion to Change asking a judge to declare the child 'independent' and terminate the order.
You must serve the Family Responsibility Office with the new Termination Order to stop garnishments. DO NOT just stop paying without an order.
Generally, yes. In Ontario, at 16, a child can withdraw from parental control. Parents cannot force them back, but they may no longer be obligated to support them.
