Family Law
Received a family court decision you believe is wrong? An appeal is one possible response, but deadlines are short and it is not the right tool for every situation. Mida Law can help you decide and act.
Before you decide to appeal
Receiving a family court decision you believe is wrong can be difficult, and the clock may already be running. An appeal is one possible response, but it is not the only one, and it is not the right tool for every situation.
This page explains what a family-law appeal is, how to tell whether an appeal is even available, the strict deadlines involved, and how Mida Law can help you decide and act. It is general information, not legal advice for your specific case.
Act promptly. If you think you may want to appeal, treat it as urgent: deadlines are short, and missing them can close the door. You can contact Mida Law, or use the urgent paid consultation option on our Request a Consultation page.

What a family-law appeal is
An appeal asks a higher court to review a decision of a lower court for legal or factual error. It is not a fresh trial and not a chance to simply re-argue your case or present it more persuasively. The appeal court reviews what happened below, on the record that was before the first judge, and it steps in only where there is a reviewable error. Understanding that difference early saves a great deal of disappointment and cost.
Appeal, or something else? Choosing the right tool
An appeal is often not the best route. Depending on your situation, a different mechanism may fit better:
A motion to change
Where parenting or support arrangements no longer work because circumstances have changed, the usual route is a motion to change, not an appeal.
Reconsideration or setting aside
In limited situations, an order may be reconsidered or set aside (for example, certain orders made without both sides present).
Correcting a slip
Minor errors in an order can sometimes be corrected without an appeal.
Choosing the wrong mechanism wastes time you may not have. One of the first things a lawyer will do is identify whether an appeal, or a different tool, is the right response.
Why identifying the correct appeal route matters
Ontario does not have a single family-appeal court. Where your appeal goes depends on which court made the order, which law the order was made under, and whether the order is final or temporary. Sending an appeal to the wrong court, or missing a leave requirement, can be fatal to it. This is one of the most important, and most technical, parts of any appeal, and it is worth getting right from the start.
At a high level:
| Order made by | Under | Appeal generally goes to |
|---|---|---|
| Ontario Court of Justice | Most family statutes (final order) | Superior Court of Justice |
| Ontario Court of Justice | Certain Children’s Law Reform Act jurisdiction orders, including Hague Convention orders | Court of Appeal for Ontario |
| Superior Court of Justice (Family Court branch) | Provincial statutes such as the Family Law Act or Children’s Law Reform Act | Divisional Court |
| Superior Court of Justice (Family Court branch) | Divorce Act orders, or certain jurisdiction and international orders, including Hague Convention orders | Court of Appeal for Ontario |
| Superior Court of Justice (regular branch) | Final family orders | Court of Appeal for Ontario |
| Any court | Temporary (interlocutory) orders, general rule | Divisional Court, with permission (leave) |
This table is a simplified guide, not a substitute for advice on your specific order. Exceptions apply.
Final versus temporary (interlocutory) orders
Whether an order is final (it finally decides a right or an issue) or temporary (procedural or interim) affects both where you appeal and whether you need the court’s permission first. The line between the two is not always obvious and is often argued about, so it is worth confirming early.
Strict deadlines
Family-appeal deadlines are short. In many family matters the notice of appeal must be served and filed within 30 days of the order. Some situations have their own timelines. If a deadline has passed, you may have to ask the court for an extension of time, which is not guaranteed.
Because the deadline can be as little as 30 days, the safest step is to get advice immediately after a decision you may want to challenge.
Standards of review, explained simply
Appeal courts do not treat every part of a decision the same way:
Errors of law
For example, applying the wrong legal test. These are reviewed strictly, for correctness.
Errors of fact, and of mixed fact and law
For example, how the judge weighed the evidence. These are given strong deference, and are overturned only for a “palpable and overriding error,” meaning an obvious error that affected the result.
Parenting and support decisions, which involve a great deal of judgment, receive particular deference. In practical terms, an appeal built on “I disagree with how the judge weighed the evidence” is much harder than one built on a clear legal error. Honest advice about which kind of error you actually have is essential.
Errors of law, fact, and mixed fact and law
Most appeals turn on identifying a genuine error of law (the strongest ground), rather than an invitation to re-weigh the facts. Mixed questions, where a legal standard is applied to the facts, sit in between. Framing the grounds of appeal accurately, and realistically, is much of the work of a good appeal.
The appeal record, transcripts, and factum
An appeal is decided on the record from the court below. In practice, an appellant usually must:
- Order and file the transcripts of the hearing.
- Assemble the appeal record and exhibits.
- Prepare a factum, a written argument setting out the grounds and the law.
Each step has its own rules and timelines, and putting the record together well takes time and care.
Fresh evidence on appeal
Appeal courts rarely allow new evidence, because an appeal reviews the decision that was made on the evidence the trial judge had. In cases involving children, courts take a somewhat more flexible approach where up-to-date information genuinely serves the child’s interests, but this remains the exception, not the rule.
Stays pending appeal
Filing an appeal does not automatically pause the order you are appealing. In particular, support obligations generally continue unless a court orders otherwise. If you need the order paused while the appeal is decided, you usually have to ask for a stay, and the court decides whether to grant one.
An important practical point: an appeal, by itself, does not buy you time from the order’s effect.
Responding to an appeal
If the other parent has appealed a decision in your favour, you are the respondent, and you also face deadlines and steps, including a responding factum. A strong response defends the decision below and holds the appeal court to the deferential standards of review. Mida Law acts for respondents as well as appellants.
Costs and practical risks
Appeals take time and carry cost, including transcript and preparation expenses, and the risk that the losing side may be ordered to pay some of the other side’s costs. A realistic, early assessment of the prospects, the cost, and the alternatives is part of deciding whether an appeal makes sense for you.
What an appeal court can and cannot do
An appeal court can:
- Dismiss the appeal.
- Allow the appeal and substitute a different order.
- Set the order aside and send the matter back for a rehearing.
- Vary the order.
It generally will not simply re-weigh the evidence or substitute its own view of the facts unless there is a reviewable error. Knowing what a win would actually look like helps set realistic expectations.
When immediate legal advice is important
Because deadlines can be as short as 30 days, and because the right route and mechanism are technical, advice soon after the decision is valuable. Even if you are unsure whether to appeal, an early consultation can tell you whether an appeal is available, what it would involve, and whether a different step would serve you better.

Frequently asked questions
How long do I have to appeal a family court decision in Ontario?
Often as little as 30 days from the order, and some matters have their own timelines. Because the window is short, get advice right away.
Is an appeal a new trial?
No. An appeal reviews the earlier decision for legal or factual error, on the record from below. It is not a chance to re-argue the case from scratch.
Can I appeal because I disagree with how the judge weighed the evidence?
That is the hardest kind of appeal. Findings of fact receive strong deference and are overturned only for an obvious, result-affecting error. A clear error of law is a stronger footing.
Does filing an appeal pause the order?
Usually not on its own. Support obligations in particular continue unless the court grants a stay, which you must request.
Should I appeal, or bring a motion to change?
It depends. If circumstances have changed, a motion to change is often the right tool; if the decision contains a legal error, an appeal may be. A lawyer can help you choose.
