Key takeaways
  • Married spouses have a set deadline for property claims: six years from separation or two years from the final divorce, whichever comes first.
  • Common-law couples are not legally required to split property acquired while living together, so their claims work differently.
  • Limitation periods can apply differently to different parts of a claim, so do not assume one date covers everything.
  • The safest approach is to get advice early and treat any deadline as already running.

If you and a former common-law partner have separated and you believe you are owed a share of a home, savings or other property, one question comes before all others: how long do you have to act? Waiting can quietly cost you the right to claim at all.

This article explains how deadlines work for married couples, how common-law claims differ, and why you should not guess at your date. How long you have for your own claim depends on the type of claim and your situation, so a lawyer can confirm it.

Start with what is clear: the married-spouse deadline

For married spouses, Ontario.ca sets the time limit for property claims at six years from the day of separation or two years from the day the divorce is final, whichever comes first. The Family Law Act also sets a period of six months after the first spouse's death.

These are the rules for the married-spouse property framework, where property acquired during the marriage is generally split equally and the spouse with the smaller share is owed an equalization payment. They are the benchmark people often hear about, but they were written with marriage in mind.

Why common-law claims are different

Common-law couples are not legally required to split property acquired while living together. Instead, a partner who contributed to property the other owns may have a right to part of it, and may need to go to court to recover that contribution.

Because a common-law claim is built on a different footing from a married spouse's equalization claim, you should not simply assume the married-spouse dates apply to you. The correct period and the date it starts depend on the kind of claim you are bringing and on the facts.

Different parts of a claim can have different clocks

The Court of Appeal has shown that a single legal proceeding can involve more than one time limit. In a case about setting aside a domestic contract, the majority held that the proceeding fell within s. 16(1)(a) of the Limitations Act, 2002, so the declaration had no limitation period, but consequential relief kept its own period, which for equalization was six years under FLA s. 7(3)(b). One judge agreed with the result but disagreed with the broad statement.

The lesson for you is practical. Even if one step in a dispute has no deadline, the money or property you actually want may still be time-limited. Do not rely on a general impression that you have plenty of time.

If a cohabitation or separation agreement exists, it may also matter. Spouses can vary the default rules by a domestic contract, and a court may set one aside in limited circumstances, such as non-disclosure of significant assets or debts.

Working out when the clock may have started

For married spouses, the starting point in the published rule is the day of separation. For common-law claims, the starting point depends on the kind of claim and the facts, so it is worth confirming with a lawyer. Rather than guessing, gather the dates that a lawyer will want.

If more than a year or two has passed since you separated, it is especially important to get advice soon.

What to do next

Treat any deadline as already running. Starting a court case is not always the first step, and there are other ways to try to resolve things. Free family mediation is available in all Ontario family courts, offered at the courthouse on the day you are scheduled to be in court. Court-connected mediation can help with property division. Whether talking or mediating affects any deadline is worth confirming with a lawyer before you rely on negotiations.

Frequently asked questions

Is the six-year deadline for married spouses also my deadline as a common-law partner?

Not automatically. The six years from separation or two years from the final divorce, whichever comes first, is stated for married spouses' property claims. Common-law claims work differently, so the right period depends on your claim and should be confirmed with a lawyer.

Does the clock start on the day we separate?

For married spouses' claims, separation is the starting point in the published rule. For common-law claims, the start date depends on the kind of claim and the facts, so a lawyer should confirm it.

Can I have more than one deadline in the same dispute?

Yes, it is possible. In one Court of Appeal decision, a declaration about a contract had no limitation period but the consequential relief, such as equalization, kept its own period.

Does mediation stop the time limit?

You should not assume so. Mediation is available through family courts, including free courthouse mediation on a court date, but whether it affects a deadline is something to confirm with a lawyer before you rely on it.
