Key takeaways
  • Equalization is a money payment of half the difference between the spouses' net family properties, not a split of each asset.
  • A court may award more or less than half only if equalizing would be unconscionable, judged by the factors in s. 5(6) of the Family Law Act.
  • Time limits apply, so a spouse who thinks equal sharing is unfair should get advice early.

You may be separating from a spouse and feel that splitting the value of your property equally would be unfair. Perhaps they ran up debts, spent savings, or the marriage was very short. Many people ask whether Ontario courts can divide property unequally.

The short answer is yes, but only in narrow circumstances. This article explains how equalization works, the high bar for departing from it, each factor a court looks at, and related tools and deadlines.

How equalization works and why it assumes equal sharing

When spouses separate with no reasonable prospect of resuming cohabitation, or a divorce is granted, the spouse with the lower net family property is entitled to one-half the difference between the two net family properties. Equalization is a payment of money. It is not a split of each asset.

The law starts from equality because child care, household management and financial provision are treated as joint responsibilities, and each spouse is seen as contributing equally to them, whether financially or otherwise. Each spouse's net family property is the value of all property they own on the valuation date, minus excluded property, their debts and other liabilities, and the net value of property (other than a matrimonial home) they owned on the date of marriage.

A spouse whose debts exceed their assets does not end up with a negative number. A negative net family property is deemed to be zero, and the other spouse does not take on any of that shortfall.

The high bar: what "unconscionable" means here

A court may award more or less than half the difference between the net family properties, but only if equalizing would be unconscionable, having regard to the factors listed in s. 5(6) of the Family Law Act. Ontario.ca describes unequal division as available only in very special situations, where an equal split would be extremely unfair to one spouse.

Being unhappy with the result, or believing you contributed more, is not enough on its own. How often a court will find the threshold met depends heavily on the facts, and a lawyer can give you a realistic view of your situation.

The eight factors, with everyday examples

The factors in s. 5(6) are listed below. Each one comes with a simple, made-up illustration to help show the idea.

A court weighs these factors together. Having one of them present does not automatically lead to an unequal result, because the test remains whether equalizing would be unconscionable.

Related tools: protecting property and acting early

If spouses are still living together but there is a serious danger that one may improvidently deplete their net family property, the other spouse may apply to have the net family properties equalized as if they were separated.

In an equalization or title application, the court may make an interim or final order to protect a spouse's claim, such as restraining dealings with property or requiring security. The court may also make an order restraining the depletion of a spouse's property that would impair or defeat a claim.

Time limits for an equalization claim

An equalization application cannot be brought after the earliest of these dates: two years after a divorce or judgment of nullity; six years after separation with no reasonable prospect of resuming cohabitation; or six months after the first spouse's death.

A court may extend a time limit in the Act if there are apparent grounds for relief, the relief is unavailable because of delay incurred in good faith, and no person will suffer substantial prejudice because of the delay. That is discretionary, so do not count on it.

What to do next

Whether your facts could meet the unconscionability bar is a question a lawyer can assess once they see your documents.

Frequently asked questions

Does the court split each asset equally?

No. Equalization is a payment of money based on half the difference between the two net family properties, not a split of each asset.

Is a short marriage enough for an unequal division?

Not automatically. A disproportionately large amount for a period of cohabitation of less than five years is one factor the court may consider, but the overall test is whether equalizing would be unconscionable.

What if my spouse's debts are bigger than their assets?

Their net family property is treated as zero, and you do not take on the shortfall.

Can I ask for an unequal split if we have not separated yet?

A court may award more or less than half only when equalizing would be unconscionable, judged by the factors in s. 5(6). If spouses are still living together and there is a serious danger that one may improvidently deplete their net family property, the other may apply to have the net family properties equalized as if they were separated, which is an equalization rather than an unequal division. How this applies depends on your situation, so it is worth confirming with a lawyer.
