Interim Equalization Payment Before Trial in Ontario

Family cases can take a long time to reach trial. If you expect to be owed an equalization payment, waiting years for the money can be hard, especially if you need it for housing, debts or legal costs.

This article explains how equalization works, what makes the amount more or less certain, and how to think about asking for an early partial payment. The rules on interim relief are technical, so this is a starting point for a conversation with a lawyer.

How equalization works

Equalization is the way Ontario divides the growth in value of what spouses built during the marriage. Under the Family Law Act, the spouse with the lesser net family property is entitled to one-half the difference between the two net family properties. This is the default rule.

Net family property is the value of all property a spouse owns on the valuation date, except excluded property, less debts and liabilities. The marriage-date deduction covers property, other than a matrimonial home, owned on the date of marriage.

Why the amount is often unclear for a long time

Several issues commonly keep the number uncertain until trial.

• Excluded property: gifts or inheritances from a third person after the date of marriage are excluded, but not for a matrimonial home.
• Tracing: property into which a gift or inheritance can be traced can also be excluded, other than a matrimonial home.
• Domestic contracts: property the spouses agreed in a domestic contract is not to be included is excluded.
• The matrimonial home: if property brought into the marriage is still the matrimonial home at separation, its marriage-date value cannot be deducted.
• Double-counting: the same property cannot be both an excluded amount and a marriage-date deduction.

If these questions are in dispute, the final figure may not be clear until they are resolved. How this affects a request for an early payment depends on your situation, so it is worth confirming with a lawyer.

Can the court change the equal share?

The court can vary the equal share only if equalizing net family properties would be unconscionable. The threshold is high, and mere unfairness is not enough. In Booth v. Bilek, the Court of Appeal upheld a 10% payment after a short cohabitation, but courts need not apply a time-weighted formula, and the result turned on its own facts.

This matters for an early payment request. If the other side says the equal share should be reduced, they are raising a contested issue, and the strength of that argument can affect how confident anyone can be about the final number.

Interest and the cost of waiting

If a court orders money paid, interest may be part of the picture. Under the Courts of Justice Act rates published by Ontario, the 2026 postjudgment interest rate is 4.0% in every quarter, and the prejudgment rate is 2.5% in every quarter of 2026. Prejudgment interest uses the rate for the quarter when the case was started, and postjudgment interest uses the rate for the quarter when the court made the order. A rate set by contract or a specific law overrides the table.

Whether and how these rates apply to an equalization payment in your case is something a lawyer should confirm. Do not assume interest will make up for years of delay.

What to do next

• Identify your valuation date and the date of marriage, and list what you and your spouse owned on each.
• Collect statements for bank accounts, investments, pensions, vehicles and debts.
• Note any gifts, inheritances or domestic contracts that might affect what is excluded.
• Ask a family lawyer whether a partial payment is realistic and what evidence they would want.
• Consider a written proposal for a voluntary advance from sale proceeds or savings, which can be quicker than a motion.

A negotiated early payment, recorded in a written agreement, is often more practical than waiting for a court order.
