What Is Form 26B Affidavit for Filing Domestic Contract With Court?
Form 26B is a legal document used to formally register a domestic contract with the appropriate court in Ontario. By filing Form 26B, you’re validating your agreement in the court’s eyes and demonstrating that all parties involved have willingly signed it.
This document applies to Separation Agreements, Marriage Contracts, Cohabitation Agreements, and Paternity Agreements. Once you file Form 26B, your contract becomes part of the official court record, making it easier to enforce if problems arise.
Purpose of Form 26B Affidavit for Filing Domestic Contract With Court
Filing your contract with Form 26B allows a court to formally accept an agreement into its official records. This gives your contract or agreement legal recognition, which is required if you ever need to enforce it.
For example, if your ex-spouse does not follow specific terms in a Separation Agreement, you can file the agreement with Form 26B. This would allow the court to make an order for compliance, which would require your spouse to abide by the agreement’s terms.
For agreements involving child or spousal support, Form 26B enables the Family Responsibility Office (FRO) to intervene and assist with enforcement. Once filed, your agreement carries more legal weight, allowing the court to intervene if needed.
Agreements You Can File With Form 26B
Form 26B is only used for domestic contracts under Ontario’s Family Law Act. These include Separation Agreements, Marriage Contracts, Cohabitation Agreements, and Paternity Agreements.
See a quick outline of each agreement below. For more information, refer to our guide, Completing Form 26B: Affidavit for Filing Domestic Contract With Court.
Ontario Separation Agreement
A Separation Agreement is a legally binding agreement that outlines how you and your ex will handle your affairs post-separation. In Ontario, this agreement defines each party’s rights and responsibilities, eliminating the need for court proceedings.
Once you and your ex sign it, a Separation Agreement becomes enforceable under Ontario’s Family Law Act. If you need to draft one, use our free Separation Agreement template to help you do it quickly and easily.
Ontario Cohabitation Agreement
A Cohabitation Agreement is a legal contract between two unmarried individuals who are in a relationship and cohabiting together. It details each person’s rights and responsibilities both while they live together and if their relationship ends.
You may want a Cohabitation Agreement if you plan to buy property with your partner or live together without getting married. It enables you to protect your assets and sets expectations for both parties. Use our free Ontario Cohabitation Agreement template to draft one seamlessly.
To learn more about how Cohabitation Agreements work in Ontario, see our Guide to Cohabitation Agreements in Ontario.
Ontario Marriage Contract
An Ontario Marriage Contract is a legal agreement between two individuals who are either married or planning to get married. If you were in a common-law relationship and had a Cohabitation Agreement, it automatically becomes a Marriage Contract once you marry.
There are two types of Marriage Contracts in Ontario: a Prenuptial (prenup) Agreement and a Postnuptial (postnup) Agreement. Both serve similar purposes but differ in timing and context.
-
Prenups help prevent future disputes by setting expectations from the beginning. They offer financial protection and transparency before a couple ties the knot.
-
Postnups give couples the opportunity to redefine the financial terms of their relationship. They allow you and your spouse to decide how to handle specific matters during your marriage or in the event of separation.

Ontario Paternity Agreement
A Paternity Agreement is a written contract between unmarried parents that outlines key matters concerning their child. These agreements may also detail custody and access arrangements, meaning where a child will live and how parenting time will be shared. They can also specify each parent’s role in deciding matters like childcare and the overall upbringing of children.
Essentially, a Paternity Agreement provides safeguards for parents and children by clearly defining everyone’s roles and responsibilities.
