Key takeaways
  • If you are served in Canada or the United States, you generally have 30 calendar days to serve and file Form 10.
  • Your answer sets out your position and can include your own claims, with extra forms for parenting and financial issues.
  • Ignoring the application can mean you lose the right to take part, and the court may decide the case without you.

Being handed a family court application can feel overwhelming, especially if you did not expect it. The papers start a legal case, and a clock starts running for your reply.

This article explains the deadline for answering in Ontario, what your answer should contain, and what can happen if you do nothing. It is general information, not advice on your own situation.

What you have been served with

A family case starts when one person files an application. That person is the applicant, and you are the respondent. Rule 8 of the Family Law Rules covers starting a case, and Rule 10 covers answering one.

The application must be served by special service, carried out by someone other than the applicant who is at least 18. After service, the applicant files an Affidavit of Service (Form 6B) with the court. If you are unsure whether the papers reached you in this way, a lawyer can confirm whether service was done properly.

The deadline to answer

If you were served in Canada or the United States, you have 30 calendar days to serve and file an answer on Form 10. If you were served outside Canada or the United States, the time is 60 days.

Outside Canada or the United States60 days

How your exact deadline works out depends on your situation, so it is worth confirming it with a lawyer. If you are close to the deadline, act first and sort out the details afterward.

What goes into your answer

In Form 10, you set out your position on the applicant's claims. You can also make claims of your own.

In support cases, you must also serve income and financial information. If you became unemployed in the last three years, that includes a complete Record of Employment or other proof of termination, plus a statement of any continuing benefits from the former employer. Start gathering these papers early, because they take time to collect.

What happens if you do not answer

If you do not serve and file an answer, you are not entitled to further notice of steps in the case, except service of the order, and you are not entitled to take part in the case. The court may deal with the case in your absence, and a date may be set for an uncontested trial.

In practical terms, that means decisions about parenting, support or property can be made without hearing your side. If you miss the deadline, speak to a lawyer or a Family Law Information Centre promptly about your options.

What to do next

Once an answer is filed, a judge must conduct at least one conference in the case. Do not wait for that step to start preparing.

Frequently asked questions

How long do I have to respond to a family court application in Ontario?

If you were served in Canada or the United States, you have 30 calendar days to serve and file Form 10. If you were served outside those countries, you have 60 days.

Do I always need to file financial information with my answer?

No. It depends on what is claimed. If support or property is in issue, you file financial disclosure. A party whose only support claim is child support in the table amount, with no property or exclusive possession claim, does not need a financial statement.

Can I still take part if I miss the deadline?

If you do not serve and file an answer, you are not entitled to take part in the case and the court may deal with it in your absence. Whether anything can be done after a missed deadline depends on the facts, so speak to a lawyer quickly.

Can I make my own claims in my answer?

Yes. Form 10 is where you give your position and can make claims of your own. If you claim parenting time or decision-making responsibility, you also file Form 35.1.
