Key takeaways
  • Equalization is one payment of money equal to half the difference between the spouses' net family properties, not a split of each asset.
  • Each spouse's net family property is their property on the valuation date, minus excluded property, debts and the value of non-home property owned at marriage.
  • A negative net family property counts as zero, and the person claiming a deduction or exclusion must prove it.

If you are separating, you have probably heard that property is "split evenly". In Ontario, for married spouses, it works differently: the law compares what each of you built up during the marriage and the spouse with more makes a payment to the other.

This article walks through that arithmetic one step at a time, with an invented example. Your own result depends on your facts, and a lawyer or accountant can confirm how the rules apply to your assets.

What equalization actually is

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. The result is a payment of money. It is not a division of each asset.

The idea behind it is that child care, household management and financial provision are joint responsibilities, and each spouse is treated as contributing equally to them, whether financially or otherwise.

This applies to married spouses. Common-law partners are not entitled to equalization under this scheme, and property generally belongs to whoever bought it, although a partner who contributed to the other's property may have a claim.

The steps, in order

The Ontario government describes the calculation this way: add up your property at separation, subtract your debts and excluded property, subtract your net property value on the date of marriage, then divide the difference between the two spouses' totals by two. The spouse with the larger total pays.

A worked example

Assume Alex and Sam are married and separate. To keep it simple, we leave the matrimonial home out for now and use descriptions rather than dollar figures, since real amounts depend entirely on your facts.

ItemAlexSam
Property on valuation dateLarger totalSmaller total
Minus debtsSome debtsSome debts
Minus excluded propertyNoneAn inheritance received after marriage
Minus net value owned at marriageSome propertySome property
Net family propertyHigherLower

Alex's net family property is higher than Sam's. You take the difference between the two and divide it by two, and Alex, as the spouse with the larger total, owes Sam that amount as an equalization payment. The payment is made in money, so Alex does not hand over half of each asset.

If a spouse's debts were greater than their assets, the result would be less than zero. A negative net family property is deemed to be zero, and the other spouse does not take on the shortfall.

Where the numbers get complicated

If you and your spouse signed a marriage contract or other domestic contract, it prevails over the Family Law Act on matters it deals with, unless the Act says otherwise. A contract can also exclude certain property from net family property.

Can the payment be more or less than half?

A court may award more or less than half the difference only if equalizing would be unconscionable, having regard to the factors in the Family Law Act. Those factors include debts incurred recklessly or in bad faith, intentional or reckless depletion of property, and an amount that is disproportionately large for a period of cohabitation of less than five years. The Ontario government describes this as available only in very special situations.

What to do next

A lawyer can check your figures, and an accountant or valuator can help with pensions, businesses and unusual assets. Courts can also order payment in instalments, or delay it for up to ten years if needed to avoid hardship, so how the payment is made may be as important as the amount.

Frequently asked questions

Do we split every asset in half?

No. Equalization is a payment of money based on half the difference between the two net family properties, not a split of each asset. Each spouse may keep the assets in their own name and the spouse with the larger total makes a payment.

What if one of us has more debts than assets?

A net family property below zero is deemed to be zero. The other spouse does not take on that shortfall.

Is the house treated like other property I owned before marriage?

No. The deduction for property owned on the date of marriage is not allowed for a home that is a matrimonial home on the valuation date, so its full value is included. An inherited or gifted family home is also counted in full.

How long do I have to make an equalization claim?

An application cannot be brought after the earliest of two years after a divorce or nullity judgment, six years after separation, or six months after the first spouse's death. A court may extend a time limit in limited circumstances, but that is not guaranteed.
