Key takeaways
  • A separation agreement is unenforceable unless it is in writing, signed by the parties and witnessed.
  • It can cover property, support and parenting, but pensions, RRSPs and CPP credits each have their own rules.
  • A court may set aside an agreement if a party failed to disclose significant assets or debts, or did not understand what they signed.

Most separating couples would rather settle than go to trial. A settlement lets you decide the terms yourselves, but it only works if it covers the right topics and is signed in the right way.

This article walks through what an Ontario divorce settlement can include, the pension and tax points that are easy to miss, and what makes the agreement binding. It is general information, and a lawyer can confirm how it applies to your situation.

What a settlement is

A settlement is usually recorded in a separation agreement, which is a domestic contract. It may cover property, support and parenting. It is a separate step from the divorce itself, because a simple divorce application is for divorce only and no other claim, such as support or property, can be made in it.

Spouses are also expected to try to work things out outside court where appropriate. The Divorce Act requires parties to try a family dispute resolution process where appropriate, which includes negotiation, mediation and collaborative law.

Topics a settlement commonly covers

TopicWhat to keep in mind
Property equalizationThe spouse with the smaller net family property is entitled to one-half of the difference.
Excluded propertyGifts or inheritances from a third party after the marriage (other than a matrimonial home), personal injury damages and life insurance proceeds may be excluded, and the person claiming an exclusion must prove it.
Child supportBefore granting a divorce, the court must be satisfied that reasonable arrangements are made for the support of any children of the marriage.
PensionsThe value of a pension plan interest is set under the Pension Benefits Act.
Parenting and supportBoth may be included in a separation agreement.

The date of separation matters because the valuation date for property can be the date the spouses separate with no reasonable prospect of resuming cohabitation. Make sure your agreement states the dates you are relying on.

Pensions, RRSPs and CPP

These assets are often the largest, and each has its own rules.

For common-law partners, different pension and CPP rules apply, including a 48-month application window for CPP credit splitting unless the other partner waives it in writing.

Making the agreement binding and durable

A separation agreement is unenforceable unless it is in writing, signed by the parties and witnessed. Even a signed agreement can be challenged. A court may set aside a domestic contract, or a provision in it, if a party failed to disclose significant assets, debts or other liabilities, did not understand its nature or consequences, or on contract-law grounds.

If you use arbitration, a family arbitration award is enforceable only if, among other conditions, each party received independent legal advice before making the arbitration agreement. In collaborative law, the lawyers' retainer includes a disqualification agreement, so both lawyers must withdraw if the matter goes to court.

Full financial disclosure is the best protection for both sides. Exchange complete statements of assets and debts before you sign.

What to do next

Once the divorce is granted, it generally takes effect on the 31st day after the judgment is made. The court may order an earlier date if special circumstances justify it and the spouses agree and undertake that no appeal will be taken, or any appeal has been abandoned.

Frequently asked questions

Does a settlement agreement have to be witnessed?

Yes. A separation agreement is unenforceable unless it is made in writing, signed by the parties and witnessed.

Can a settlement be undone later?

Sometimes. A court may set aside a domestic contract or a provision in it if a party failed to disclose significant assets or debts, did not understand its consequences, or on contract-law grounds.

Can the settlement include my spouse's pension?

Yes, but a lump-sum transfer from the plan must be provided for in a court order, arbitration award or domestic contract, and cannot exceed 50 per cent of the imputed value.

Is there a deadline for property claims?

Yes. The equalization limitation is the earliest of two years after a divorce or nullity judgment, six years after separation, or six months after the first spouse's death, though a court may extend it in limited circumstances.
