If you are served with a Form 8 Application in Ontario, you have exactly 30 calendar days to serve and file your Form 10 Answer if you reside in Canada or the USA. If you live internationally, you have 60 days. Failing to meet this strict deadline means you could be “noted in default,” allowing the court to make permanent decisions about your children and finances without your input.
Being served with family court documents can be an incredibly shocking and overwhelming experience. Suddenly, a process server hands you a massive stack of papers outlining your ex-partner’s demands for decision-making responsibility, parenting time, spousal support, or property division. It is common to feel paralyzed by fear or anger, but ignoring these documents is the worst possible reaction.
In Ontario, the Family Law Rules dictate a very rigid timeline for you to respond. ⚠️ You cannot wait until you feel ready; the legal clock starts ticking the moment the documents touch your hands. To protect your rights, your assets, and your relationship with your children, you must formally reply using a Form 10 Answer. Below, we guide you through the exact steps, costs, and critical timelines required to properly defend yourself in the Superior Court of Justice.
Step-by-Step Process to File an Answer in Ontario
Whether you are dealing with a family court in Brampton, Toronto, or Ottawa, the procedural steps are mandatory. Responding is not as simple as writing a letter to the judge; you must follow strict legal formatting.
Step 1: Note the Exact Date of Service
The 30-day countdown begins on the day you were legally served. Write this date down immediately. If you were served on a Tuesday, day one of your countdown is Wednesday. Weekends and holidays are fully included in this 30-day calculation, meaning time passes very quickly.
Step 2: Retain a Family Law Firm Quickly
Because family law is highly complex, attempting to draft an Answer yourself often leads to costly mistakes. 🔍 You should schedule consultations with local Ontario family lawyers within the first week of being served. This gives your chosen lawyer enough time to gather your financial documents and draft a strong legal strategy.
Step 3: Draft the Form 10 Answer
Your lawyer will help you draft the Form 10: Answer. In this document, you will go through the Applicant’s claims one by one and state whether you agree, disagree, or have no knowledge of the allegations. If you have your own demands-such as asking for primary parenting time or child support-your lawyer will draft a “Form 10: Answer and Claim by Respondent.”
Step 4: Prepare Mandatory Financial Disclosure
If the dispute involves any form of child support, spousal support, or property equalization, you cannot simply file the Answer alone. You must also serve a sworn Form 13 or Form 13.1 Financial Statement. This requires gathering your T4s, Notices of Assessment from the CRA, pay stubs, and recent bank statements.
Step 5: Serve and File the Documents
Before the 30-day deadline expires, your lawyer must serve your Form 10 and Financial Statement on your ex-partner’s lawyer. Once successfully served, your lawyer will immediately file the documents, along with an Affidavit of Service, at the local Family Court to officially stop the 30-day clock.
How Much Does It Cost to Respond in Ontario?
Defending a family law application requires a financial investment in proper legal representation. As of May 2026, here are the general costs in CAD:
- Court Filing Fees: Filing a standard Form 10 Answer is usually free. However, if you add your own claims (Answer and Claim by Respondent), you must pay a filing fee of roughly $167 CAD.
- Lawyer Retainers: Most family law firms in Ontario will require an initial retainer between $3,500 and $7,500 CAD to review the applicant’s materials, gather your financial data, and draft your Answer.
- Process Server Fees: While lawyers can often serve the opposing law firm via email, if the Applicant is self-represented, you may need a process server, costing around $100 to $200 CAD.
Timelines You Must Memorize
Do not wait until day 28 to hire a lawyer. Gathering CRA documents and drafting sworn affidavits takes significant time. 🕘

Frequently Asked Questions (FAQ)
What happens if I miss the 30-day deadline?
If you fail to file your Answer within 30 days, your ex-partner can file a requisition to have you “noted in default.” Once noted in default, the court assumes you agree with everything your ex asked for. The judge can then hold an Uncontested Trial and issue a final, binding court order without giving you any further notice.
Can I ask the Applicant for an extension?
Yes. It is very common for lawyers to grant each other professional courtesies. Your lawyer can contact the Applicant’s lawyer to negotiate an extension of time to file the Answer. However, this extension must be explicitly agreed upon in writing to be safe.
What if day 30 falls on a Saturday or a holiday?
Under the Family Law Rules, if your 30-day deadline expires on a Saturday, Sunday, or a statutory holiday when the court counters are closed, your deadline automatically rolls over to the very next business day.
Do I have to go to court on day 30?
No. The 30-day deadline is strictly for serving and filing the paperwork. You do not physically stand in front of a judge on that day. The court will schedule a Case Conference for a later date once the pleadings (the Form 8 and Form 10) are fully filed.
