You’ve been paying child support for years, and you’re ready for it to end. Maybe your kid graduated, got a job, or became independent.
Stopping child support payments in Ontario requires a proper legal process—you can’t just stop sending money.
Let me walk you through the right way to end these obligations without creating legal nightmares for yourself.
Never Stop Paying
This is rule number one: don’t stop payments just because you think support should end. I don’t care if your kid is 25 with a full-time job—stopping without legal termination creates massive problems.
The Family Responsibility Office doesn’t care about your logic or reasoning. They enforce court orders exactly as written until officially notified of changes.
Unilateral stopping triggers wage garnishment, license suspension, and the accumulation of arrears with interest.
Consequences of Stopping Without Permission
Here’s what happens when you just quit paying:
- Wage garnishment takes money directly from your paycheque
- A driver’s license suspension prevents you from driving legally
- Passport denial is blocking international travel
- Tax refund seizure, redirecting your money to arrears
- Credit bureau reporting is destroying your credit score
- Potential contempt of court charges
When You’re Legally Entitled to Stop?
Knowing when support should end helps you time your termination application properly. Your child finishing university, landing a full-time career job, getting married, or becoming genuinely independent all justify ending support.
If your 22-year-old graduated with their degree and started working full-time, earning $50,000 annually, that’s clear independence.
Support obligations for that child should end. Marriage or long-term cohabitation by your adult child typically ends support, too.
Signs Your Child Is Truly Independent
Courts look for these indicators:
- Full-time employment with adequate income for self-support
- Living separately and paying their own rent/mortgage
- Managing all personal expenses without parental help
- Completed post-secondary education or training
- No ongoing educational pursuits requiring support
Review Your Court Order or Agreement
Before doing anything, pull out your court order or separation agreement and actually read it. Some orders include specific termination conditions or procedures you must follow exactly.
Your agreement might say “child support continues until the child completes post-secondary education, reaches age 21, or becomes self-sufficient, whichever occurs last.” These specific terms matter—they’re the contract you agreed to, or the court imposed.
Common Agreement Termination Clauses
Different agreements handle termination differently. Your document might specify:
- Automatic termination at a specific age (rare but exists)
- Requirement for a written notice to the other parent
- Mandatory mediation before court applications
- Specific evidence is needed to prove independence
- Process for mutual agreement to terminate
Understanding the terms of a separation agreement helps you interpret what your documents actually require.
File a Motion to Change
The formal legal process requires filing a Motion to Change with the court. This application asks the judge to modify or terminate your existing child support order based on changed circumstances.
You’ll complete specific court forms explaining why support should end. Form 15: Motion to Change and supporting affidavit detailing your child’s current circumstances—their employment, income, living situation, and independence.
Required Documentation for Filing
Gather these materials before filing:
- Completed Motion to Change forms
- An affidavit sworn before a commissioner explaining the circumstances
- Financial statements showing current income
- Evidence of the child’s independence (discussed below)
- Copy of existing support order or agreement
- Filing fee payment ($200-300)
Gather Evidence of Independence
Courts decide based on evidence, not your feelings or assumptions. Build a strong case with documentation proving your child is genuinely independent and self-sufficient.
Employment letters from your child’s employer showing full-time status and salary work great. Pay stubs covering several months demonstrate consistent income, not just temporary employment.
Bank statements showing that your child pays their own rent, utilities, groceries, and other living expenses demonstrate financial independence.
Types of Evidence That Work
Strongest evidence includes:
- Employment letter confirming full-time status and salary
- Three months of pay stubs showing consistent income
- Lease agreement or mortgage in the child’s name
- Utility bills paid by your child
- Bank statements showing financial independence
- A graduation certificate if education has just been completed
- Tax return showing child’s income and independence
- Marriage certificate if the child is married
Understanding financial aspects of separation helps you gather appropriate documentation.
Notify the Family Responsibility Office
Once you have a court order or written agreement terminating support, immediately notify FRO.
Don’t assume they’ll find out automatically or that you can stop paying once you have the paperwork.
Send FRO certified copies of the court order or agreement ending support. Include a formal letter explaining that support has been terminated effective [date] per the attached order.
FRO Notification Process
Here’s how to properly notify them. Follow these steps carefully:
- Make certified copies of the termination order/agreement
- Write a formal letter referencing your case number
- State the effective termination date clearly
- Send via registered mail for proof of delivery
- Keep copies of everything you send
- Continue payments until written confirmation is received
If Your Ex Won’t Agree
Sometimes your ex refuses to acknowledge that your child is independent, even with overwhelming evidence. They want support to continue, either because they genuinely believe the child still needs it or because they want to keep getting money.
When you can’t reach an agreement, your Motion to Change becomes contested. You’ll both file evidence and arguments.
The court might order a settlement conference where a judge tries to help you reach an agreement.
Contested Motion Steps
The contested process looks like this:
- You file a Motion to Change with evidence
- Your ex files responding materials opposing termination
- Court schedules case conference for settlement discussion
- If no agreement, a settlement conference with a judge facilitation
- Still, no deal means a trial with a full evidence hearing
- The judge makes a final decision based on all the evidence presented
Mediation services offer a middle ground between doing nothing and full-court battles.
What About Arrears?
Maybe you already stopped paying months ago before getting a proper termination. You now owe arrears, and FRO is garnishing your wages. Can you fix this?
Courts can terminate support retroactively from when circumstances actually changed, not just from when you filed your motion.
If your child became independent in January but you didn’t file until June, the court might terminate support effective January.
Retroactive Termination Possibilities
However, this isn’t guaranteed. Courts are less likely to provide complete retroactive relief if you waited too long. They expect reasonable promptness:
- Filing within 1-3 months of independence: Strong chance of complete retroactive termination
- Filing within 3-6 months: Possible partial retroactive relief
- Filing 6-12 months later: Less likely to get retroactive termination
- Waiting over a year: Minimal chance of backdating
Partial Termination for Multiple Children
If you’re paying support for multiple children and only one becomes independent, support doesn’t end completely—it reduces. File Motion to Change recalculating support based on remaining dependent children.
Federal Child Support Guidelines tables show reduced amounts as the number of children decreases.
If you were paying $1,200 monthly for two kids and one becomes independent, you’ll now pay whatever the table shows for one child at your income level.
Recalculating for Remaining Children
The process is identical to complete termination. You’ll need:
- Evidence that one specific child is now independent
- Current income information for updated calculations
- Reference to the child support tables for the new amount
- Agreement or court order reflecting reduced support
Understanding parenting responsibilities helps you navigate support for multiple children.

Get Legal Advice First
Before filing anything, consult a family lawyer. They’ll assess whether you have legitimate grounds for termination and what evidence you need.
Lawyers prevent expensive mistakes like filing prematurely before you’ve gathered sufficient evidence, or waiting too long after your child became independent, reducing the possibility of retroactive relief.
They know local judges’ tendencies and can predict how strong your case is.

FAQs
Can I stop paying child support when my child turns 18?
Not automatically. Support continues if your child is in school or unable to support themselves.
What if I stop paying without court permission?
FRO will garnish your wages, suspend your driver’s license, seize tax refunds, and accumulate arrears with interest.
How long does it take to stop child support?
Uncontested terminations typically take 2-4 months. Contested cases requiring trial can take 6-12+ months.
Can I get a refund for overpayments?
If support terminates retroactively, overpayments get credited or refunded. File your Motion to Change promptly when circumstances change to maximize retroactive possibilities.
What if my child is 22 and working full-time?
That’s likely legitimate grounds for termination. Gather employment evidence and file Motion to Change.
Does my ex have to agree to stop support?
No, but agreement makes the process much faster and cheaper. If your ex won’t agree, the court decides based on evidence whether support should end.
What evidence do I need to stop supporting?
Graduation certificates, employment letters, pay stubs, bank statements, lease agreements, tax returns—anything proving your child is financially independent.
Can I support a restart if my child loses their job?
Possibly, depending on circumstances. If they become dependent again, your ex can apply to have support reinstated.
What about the arrears I already owe?
Past arrears don’t disappear when ongoing support ends. You still owe that money. Negotiate payment plans if you can’t pay a lump sum.
How much does it cost to file a Motion to Change?
Court filing fees are $200-$300; untested cases requiring trial cost significantly more.
What if we had an informal agreement to stop?
Informal agreements don’t count. You need a formal written agreement filed with the courts or a court order.
Can I stop supporting if my child drops out of university?
Usually, yes, if they’re not pursuing other education and aren’t working toward independence. But temporary struggles don’t automatically end support.
