Once your adult child finishes post-secondary education and becomes financially independent, child support does not end automatically in Ontario. You must formally terminate it by filing a Consent Motion to Change (Form 15B) with your ex-partner, or by filing a standard Motion to Change (Form 15) if they refuse to agree.
Many parents across Ontario celebrate when their child finally graduates from college or university and lands their first full-time job. However, the financial relief you expect might not arrive right away. There is a widespread myth that child support automatically vanishes the moment a child turns 18 or graduates. 📝
In reality, the Family Responsibility Office (FRO) will simply keep garnishing your wages until a judge explicitly tells them to stop. Under Ontario family law, an adult child is generally no longer entitled to support once they finish school and are capable of supporting themselves, but the legal paperwork must reflect this new reality.
This guide will explain how to legally prove your child is independent, the fastest way to end your payments if your ex-partner agrees, and the steps to take if you are forced to fight it out in family court. We will also discuss when it is highly recommended to consult a local law firm to stop the overpayments.
Step-by-Step Process in Ontario
Whether your original support order was made in Toronto, Ottawa, Mississauga, or London, the process to modify it is handled by the Superior Court of Justice or the Ontario Court of Justice. The steps you take depend entirely on how cooperative your ex-partner is. 📍
It is crucial that you do not simply cancel your auto-deposit or tell your employer to stop the FRO deductions. Taking the law into your own hands will result in massive penalties.
Step 1: Confirm the Child is Legally Independent
Before you file any paperwork, you must gather evidence that the adult child is no longer a “child of the marriage.” This generally means they have completed their first post-secondary degree or diploma and are no longer enrolled in school full-time. ❗
If the 22-year-old child is working full-time, living on their own, or has gotten married, they are typically considered financially independent. However, if they have a severe disability that prevents them from working, the support obligation may continue indefinitely.
Step 2: Ask Your Ex-Partner for Consent
The easiest and cheapest way to end child support is through mutual agreement. Reach out to your ex-partner and explain that because the child has graduated and is working, the support payments should legally end.
If they agree, you can both sign a Form 15B (Consent Motion to Change). This is a joint request asking the judge to officially terminate the support order without the need for a messy courtroom battle.
Step 3: File a Motion to Change (If They Refuse)
If your ex-partner ignores you or insists that you must keep paying because the adult child wants to take a “gap year” or travel, you will have to file a contested Form 15 (Motion to Change). 💪
You must serve this paperwork to your ex-partner, along with a sworn affidavit proving the child is independent. You may need to attach evidence such as the child’s graduation photos, their LinkedIn profile showing their new job, or a copy of their college diploma.
Step 4: Send the New Order to the FRO
Once the judge reviews your consent form or hears your contested motion at a virtual hearing, they will sign a new court order officially terminating the child support.
The process is not over until you send this new signed order directly to the Family Responsibility Office. Only then will the FRO send a notice to your employer to stop the wage garnishment.
How Much Does it Cost in Ontario?
The cost of ending your child support obligation varies wildly. A cooperative ex-partner makes the process nearly free, while a bitter dispute can drain your savings. 💰
Here is a breakdown of the typical costs you might face:
| Action / Service Type | Estimated Cost (CAD) | Who Pays? |
|---|---|---|
| Form 15B (Consent Motion) | $0 (No court filing fee) | N/A |
| Form 15 (Contested Motion) | $160 (Court fee) | The Applicant |
| Lawyer (Drafting Consent) | $1,000 – $2,500+ Flat Fee | Often split 50/50 |
| Lawyer (Full Court Battle) | $5,000 – $15,000+ | Each parent pays their own |
If you have severely overpaid because your ex-partner hid the fact that the child dropped out of university two years ago, you can ask the judge to order a retroactive reimbursement. The judge may force your ex-partner to pay back the thousands of dollars you overpaid.
How Long Does the Process Take?
If both parents sign a Consent Motion to Change, the timeline is incredibly fast. A judge can usually review the paperwork in their office and sign the termination order within 4 to 8 weeks. ⏱
If the motion is contested and your ex-partner files a response demanding continued support, your case enters the family court backlog. Getting a final decision from a judge in a contested case generally takes 6 to 12 months.
While you wait for your court date, you must continue to pay the original child support amount. If you stop paying prematurely, the FRO will register you as being in arrears and may suspend your driver’s licence.
Frequently Asked Questions (FAQ)
Does child support end if the adult child moves back home?
Not necessarily. If the 23-year-old child moves back into your ex-partner’s basement but is working full-time and not attending school, they are generally considered independent, and support can end. Simply living at home does not automatically make an adult child a dependent.
What if the child takes a gap year to travel?
If an adult child takes a gap year to travel Europe or work at a ski resort, the court generally views them as independent for that specific year, meaning support can be paused or terminated. However, if they enroll in university the following year, the support obligation may resume.
Do I have to pay for a second university degree?
It depends on your family’s standard of living and the child’s career path. Judges generally expect parents to support a child through their first undergraduate degree. Ordering a parent to pay for a Master’s degree or medical school is less common but still possible in wealthy families.
Will the FRO refund me if I overpaid?
The FRO will only adjust your account based on a new court order. If the judge explicitly orders that support ended 12 months ago and your ex must repay you, the FRO will register a credit on your file. If your ex refuses to refund the money, the FRO can help enforce the collection.
Should I hire a law firm to end my child support?
If your ex-partner agrees, you might be able to file the consent forms yourself. However, if your ex-partner is demanding thousands of dollars for unnecessary college expenses or hiding the child’s employment status, a local family law firm is crucial to cross-examine their claims and stop the unfair payments.
