Key takeaways
  • Married spouses must generally split property acquired during the marriage equally when it ends, and the balancing payment is called an equalization payment.
  • Common-law couples are not legally required to split property acquired during the relationship.
  • The deadline to go to court over an equalization payment is six years from separation or two years from the final divorce, whichever comes first.
  • A separation agreement lets spouses divide property as they choose, but it is hard to change later.

Dividing a house, savings, pensions and debts is often the hardest part of a separation. A separation agreement lets you decide how this happens, instead of leaving it to a court.

This article explains the Ontario rules that frame the discussion, how the equalization calculation works, and what to write down so the agreement is clear. It is general information, and your facts may change the answer.

Married and common-law couples are treated differently

On Ontario.ca, married spouses must generally split property acquired during the marriage equally when it ends. The full value of the family home is shared even if one spouse owned it before the marriage or received it as a gift or inheritance.

Common-law couples are not legally required to split property acquired during the relationship. Each generally keeps what they bought, and a partner who contributed to the other's property may need a court order to recover the contribution. A cohabitation or separation agreement can set out property rights. If you are unmarried, your agreement matters even more, because the default rules do not do the dividing for you.

How equalization is calculated

The balancing payment between married spouses is called an equalization payment. Ontario.ca describes the steps: start with the total property each spouse owned at separation, less debts and excluded property. Then subtract the property owned at marriage, less debts, excluding the family home. A negative result counts as zero.

Next, subtract the smaller spouse total from the larger and divide by two. The spouse with the larger total pays that amount.

StepWhat you do
1Add up property owned at separation, then subtract debts and excluded property
2Subtract property owned at marriage, less debts, not counting the family home
3If the result is negative, treat it as zero
4Subtract the smaller total from the larger total and divide by two; the spouse with the larger total pays the result

Valuing things like a business, a pension or a home can be technical. A lawyer or accountant can help you agree on values.

Excluded property and unequal division

Some property can be left out of the calculation. Excluded property includes gifts or inheritances from someone other than the spouse (other than the family home), life insurance proceeds on a death, personal injury money, and property the spouses agree to exclude.

Courts divide unequally only where an equal split would be extremely unfair. If you are planning an unequal split in your agreement, it helps to record why, so the reasoning is clear later.

What to record in the agreement

Ontario.ca says separation agreements let spouses divide property as they choose, that each should have their own lawyer review it, and that it is hard to change later. That makes precision important. Consider recording the following.

How your agreement about debts affects what a lender can ask of each of you depends on your situation, so it is worth confirming with a lawyer. Ask a lawyer how this works for your loans, and consider speaking to the lender about changes to joint accounts or mortgages.

Timing and what to do next

To go to court over an equalization payment, the deadline is six years from separation or two years from the final divorce, whichever comes first. Do not let negotiations drift without checking which date applies to you.

Support and property are linked in practice, but they are separate issues. If support is part of the agreement, filing it with the court allows enforcement through the Family Responsibility Office.

Frequently asked questions

Do I get half of everything if we are married?

Not exactly. Married spouses generally split property acquired during the marriage equally, and the balancing payment is an equalization payment. Excluded property, such as most gifts and inheritances, is treated differently.

Is the family home treated differently?

Yes. The full value of the family home is shared even if one spouse owned it before the marriage or received it as a gift or inheritance. In the calculation, the home is not subtracted as property owned at marriage.

Do common-law partners get equalization?

No. Common-law couples are not legally required to split property acquired during the relationship, though a partner who contributed to the other's property may need a court order to recover the contribution. A cohabitation or separation agreement can set out property rights.

How long do I have to go to court about equalization?

The deadline is six years from separation or two years from the final divorce, whichever comes first. A lawyer can confirm which date applies to you.
