  • The most common source of delay isn't anything dramatic — it's small inconsistencies.
  • If you're not filing jointly, the other spouse needs to be formally served with the application using an approved method, and proof of that service needs to reach the court file.

Most divorce applications in Ontario are uncontested — the spouses agree the marriage is over and there's nothing left for a judge to fight over. That should make them quick to process. In practice, plenty of otherwise straightforward files get sent back, questioned, or stalled, and almost always for the same handful of preventable reasons.

Knowing what trips other people up is the easiest way to avoid it happening to you.

The Mistakes at a Glance

MistakeWhy it delays youHow to avoid it
Inconsistent facts across documentsThe application and affidavit need to tell the same story; contradictions invite questionsHave one person review every document together before filing
Outdated court formsCourts routinely reject or flag filings that use retired form versionsConfirm you're using the current version of every required form
Improper service on the other spouseWithout valid service, or an order dispensing with it, the file can't move to a decisionUse an approved method of service and keep proof of it
Vague or missing child support arrangementsA judge must be satisfied that reasonable arrangements exist for any children before granting the divorcePut support and parenting arrangements in writing before filing
Overlooking the federal registry feeApplications can sit incomplete without all required accompanying feesConfirm every applicable fee before you submit
Filing while a dispute is still unresolvedA live disagreement makes the file contested, not uncontestedResolve outstanding issues first, or expect a different, slower process

Paperwork Mistakes

The most common source of delay isn't anything dramatic — it's small inconsistencies. A separation date that differs between the application and the affidavit. A name spelled differently across documents. A form that's one version behind the current one. Ontario's Family Law Rules set out exactly which forms apply and how they need to be completed, and each of these mistakes is easy to fix, but only if someone catches it before filing rather than after the court flags it.

Service Mistakes

If you're not filing jointly, the other spouse needs to be formally served with the application using an approved method, and proof of that service needs to reach the court file. Assuming a text message, a phone call, or handing documents over informally counts as service is one of the more common, and most disruptive, errors — it can mean the application simply can't proceed until proper service happens.

Financial and Support Mistakes

Courts won't grant a divorce until satisfied that reasonable arrangements have been made for the support of any children of the marriage. An application that's silent, vague, or clearly inadequate on this point is a routine reason a file gets sent back for more information, even where the divorce itself is otherwise completely uncontested.

How to Catch Errors Before You File

Why "Close Enough" Doesn't Work With Sworn Documents

An affidavit is a sworn legal document, not a rough summary. Courts treat inconsistencies in sworn material seriously, because the whole point of an affidavit is that its contents are attested to be accurate. A rounded-off date, a guessed address, or a detail copied from memory instead of confirmed against a document can look like carelessness at best and raise credibility questions at worst. Taking the extra few minutes to verify each fact before it's sworn is one of the cheapest ways to avoid an entirely preventable delay.

Frequently asked questions

What happens if my application gets sent back?

Typically, the court identifies what's missing or inconsistent and gives you the chance to correct and refile the specific document, rather than rejecting the whole case permanently.

Does a small typo really cause a delay?

It can, particularly if it creates a factual inconsistency between documents. A misspelled name is usually harmless, but a mismatched date or address can prompt questions.

Can my spouse cause delays even if we agree the divorce should happen?

Yes. If service isn't completed properly, or if they don't respond to something required of them, the file can stall even where both of you want the same outcome.

Is it faster to fix mistakes myself, or hire a lawyer once a file has already stalled?

It depends on what triggered the delay, but a lawyer who regularly handles these filings can usually spot exactly what the court is asking for and correct it without a second round of back-and-forth.
