Key takeaways
  • When married spouses separate, the spouse with the lower net family property is entitled to one-half of the difference between the two spouses' net family properties.
  • Property you owned on the date of marriage is deducted, and gifts and inheritances from third parties can be excluded from the calculation.
  • Spousal support is not automatic, and it depends on need and the other spouse's ability to pay, or on an agreement that provides for support.
  • Common-law partners are treated differently from married spouses for property, so the label on your relationship matters.

If your marriage ended after a year or two, you may wonder whether the usual rules about dividing property and paying support really apply to you. It can feel as if a short marriage should mean a clean break, with each person leaving with what they brought in.

The answer is more nuanced. A short marriage does not switch off Ontario's family property rules, but it often changes the numbers a great deal. This article explains how equalization, support and pension credits work in general, and where you should confirm details with a lawyer.

Does a short marriage still count for property?

For married spouses, Ontario's Family Law Act provides that when spouses separate with no reasonable prospect of resuming cohabitation, the spouse whose net family property is lower is entitled to one-half of the difference between the two net family properties. That is the equalization payment.

Net family property is the value of all property a spouse owns on the valuation date, except excluded property, less debts and liabilities, and less the net value of property owned on the date of marriage. The valuation date is generally the date you separate with no reasonable prospect of resuming cohabitation.

In a short marriage, that last deduction does a lot of work. If most of what you own was yours before the wedding, it is subtracted, and what is left to compare may be small. Property owned before the marriage is usually shared only for any increase in its value.

What is shared and what stays yours

A court can divide property unequally only where an equal split would be unconscionable, which Ontario.ca describes as extremely unfair to one spouse. How that applies to you depends on your situation, so it is worth confirming with a lawyer.

Spousal support after a short relationship

Spousal support is not automatic. You may qualify if you were married, lived together as a couple for at least three years, or had a child together in a relationship of some permanence, and you must show need and the other spouse's ability to pay, unless an agreement provides for support.

Amount and duration are set by negotiation or by a judge, who looks at income differences, child care, age and health, and the roles each person played in the relationship. The Spousal Support Advisory Guidelines are only guidelines. Fault is not part of the picture: a court making a spousal support order shall not consider misconduct in relation to the marriage.

Child support is separate. Parents must support an unmarried minor child to the extent they are capable, and the court looks at current and future means, age, health and the accustomed standard of living.

Spousal supportPossible if need and ability to pay are shownPossible after three years of continuous cohabitation, or a relationship of some permanence with a child

If you were not married, other legal routes may exist for property claims, but how they work and their deadlines depend on your facts, so get advice early.

CPP credits and next steps

Canada Pension Plan credits earned during the time you lived together can be split. For separated spouses, the tests include having lived together at least 12 consecutive months and apart at least 12 consecutive months. Only credits from the cohabitation period are divided, and the split is permanent. CPP credits are handled this way instead of through equalization.

Equalization claims have deadlines, so do not wait too long to get advice.

Frequently asked questions

Can I get half of everything after only one year of marriage?

Not necessarily. Equalization is half of the difference between the two spouses' net family properties, not half of everything. Property owned on the date of marriage is deducted, and gifts and inheritances may be excluded, which affects the result.

Does the home get treated differently in a short marriage?

The full value of the family home is shared even if it was owned before the marriage, gifted or inherited, unless the spouses agree otherwise. A marriage contract or separation agreement can change that result.

Will cheating affect what I receive?

Misconduct in relation to the marriage is not considered when a court makes a spousal support order. A one-year separation is enough to ground a divorce, so fault is not required. How fault might matter for other issues depends on your situation, so it is worth confirming with a lawyer.

Can I still claim if we were common-law?

Common-law partners are not spouses for equalization, and they are not legally required to split property acquired together. Spousal support may still be available if the cohabitation or child tests are met. A lawyer can explain other property claims that may apply.
