Form 15 A Notice of Motion and Supporting Affidavit

Who Needs Form 15A: Notice of Motion and Supporting Affidavit?

Form 15A is for anyone involved in an Ontario family law case who wants to ask the court for a specific order. Whether you’re requesting child support, spousal support, parenting time, or another type of temporary or procedural order, Form 15A is the starting point for your motion—a formal request for the court to make a decision.

You’ll use this form when:

  • You need the court to decide an issue before trial,
  • You’re seeking temporary relief, like an interim order,
  • You’re responding to a motion filed by the other party.

Form 15A combines two important documents in one:

  • The Notice of Motion, which tells the court and the other party what order you’re asking for, and
  • The Supporting Affidavit, where you explain the facts and reasons for your request.

What Is Form 15A: Notice of Motion and Supporting Affidavit?

Form 15A is a sworn legal document that does two things:

  1. Notice of Motion:
    • States the date and time of the court hearing,
    • Lists the orders you’re asking the court to make,
    • Informs the other party they have a right to respond.
  2. Supporting Affidavit:
    • Provides a clear, detailed explanation of your situation,
    • Shares facts that support your request,
    • Includes details about your family, finances, or other relevant information.

This form helps ensure that both the court and the other party understand your request and the reasons behind it.


Where Is This Affidavit Submitted?

Form 15A is filed with the Ontario Family Court. Once it’s properly sworn and filed, you must serve it on the other party—this means delivering a copy to them so they have a chance to respond.

The court will then review your motion and affidavit as part of your case.


Why You Need a Notarized Affidavit

Form 15A is a legal affidavit, which means it must be sworn or affirmed in front of a notary public, commissioner of oaths, or lawyer.

Notarizing the form confirms that:

  • The information you’ve provided is true,
  • You understand the legal importance of your statement,
  • The court can rely on your affidavit to make a fair decision.

Without notarization, your motion may be delayed, rejected, or considered incomplete.


How to Complete and Notarize Form 15A

Here’s a simple step-by-step guide to filling out Form 15A:

  1. Fill in the names of the parties and the court file number.
  2. Write your Notice of Motion:
    • Clearly state the order(s) you’re asking for (e.g., child support, parenting time).
    • Include the date and time of the hearing.
  3. Write your Supporting Affidavit:
    • Explain the facts of your case in clear, numbered paragraphs.
    • Include details like dates, amounts, and events that support your motion.
  4. Attach any exhibits or documents you’re relying on, labelled (e.g., “Exhibit A”).
  5. Swear or affirm the form in front of a notary public, lawyer, or commissioner of oaths.
  6. File the form with the court and serve a copy on the other party in your case.

Final Note

Form 15A: Notice of Motion and Supporting Affidavit is a crucial document in Ontario family law cases. It explains what you’re asking for, why you’re asking, and the facts that support your request.

By completing the form clearly, swearing it properly, and serving it on time, you help the court understand your situation and keep your case moving forward.
