Can I challenge the judge's decision about my child support if it happened over a month ago?

Jurisdiction: Canada • Practice Area: Labor Standards • Responsible editor: Cong Ho• Published November 2, 2026

Quick Summary

It depends on whether you can convince a judge to grant an extension. While the standard 30-day window to appeal has passed, a court may still allow an appeal if you can demonstrate special grounds.

The situation

I am currently living in Canada and dealing with a very difficult separation. Last month, on the 10th of October, a judge made a final decision regarding my monthly child support payments. My ex-partner was awarded $1,200 every single month, which is far more than I can afford on my current salary. I felt the amount was completely unfair because the judge didn't consider my recent loss of overtime labour at my job. I tried to speak with my ex's solicitor to see if we could renegotiate the amount privately, but they refused to budge and said the court order is set in stone. I have been sitting on this for a few weeks trying to gather my finances to hire someone to help me, but I just realised that it has now been over thirty days since that court date on the 10th. I am incredibly stressed about this huge amount of money being taken from my pay cheque every month. Since I missed that thirty-day window, is there any way I can still ask a higher court to look at my case and change the order, or am I stuck with this decision forever?

Detailed Analysis

Under the Divorce Act, there is a strict time limit for appealing a court order. Specifically, "No appeal lies from an order made under this Act more than thirty days after the day on which the order was made"[1]. Because your judge made the decision on October 10th and it is now more than 30 days later, you have missed the standard window to file an appeal. An appeal is a formal request to a higher court to review and change a lower court's decision.

However, you are not necessarily stuck with this decision forever. The law provides a way to ask for more time. An appellate court or a judge has the power to "either before or after the expiration of the time fixed by subsection (3) for instituting an appeal, by order extend that time"[1]. This means you can apply to have the deadline extended. To succeed, you must show "special grounds"[1]. The law does not define exactly what counts as "special grounds," so it is uncertain whether your loss of overtime pay will be considered sufficient to justify an extension.

If an extension is granted and your appeal is successful, the higher court has broad powers. They may "allow the appeal and (i) render the judgment or make the order that ought to have been rendered or made... or (ii) order a new hearing where it deems it necessary to do so to correct a substantial wrong or miscarriage of justice"[1]. This could potentially result in a recalculation of your $1,200 monthly payment based on your actual income.

Additionally, if you are living in a different province than your ex-partner, you may have other avenues to seek a change. A former spouse may "commence a proceeding to obtain, vary, rescind or suspend, retroactively or prospectively, a support order"[2]. This is a separate process from an appeal and focuses on changing an existing order due to changing circumstances.

Please note that state, provincial, or local law may add further rules regarding court procedures and filing requirements.
