Separation Agreement (Ontario) by OLL

Open Legal LibraryUpdated 17 Aug 2026

This separation agreement allows residents of Ontario to settle property division, support payments, and parenting arrangements following a marriage or common-law relationship breakdown. It provides structured options for equalization payments, the treatment of the matrimonial home, and child support calculated under the Federal Child Support Guidelines.

SEPARATION AGREEMENT

This template is for two people in Ontario, married or unmarried, who have separated and wish to record how they are settling property, support and (where they have children together) parenting arrangements. It is not for people who are still living together and want a domestic contract governing a future separation (use cohabitation-agreement or marriage-contract instead), and it is not a substitute for a court order. Not suitable for use in Quebec.

Drafting notes appear in italics and are to be deleted before execution. Square brackets mark information to be filled in. Delete any inapplicable optional clauses and Parts, then renumber, before execution.

⚠️ This Agreement can be set aside. A court can set aside all or part of a domestic contract — including a separation agreement — where a party failed to disclose to the other significant assets, debts, or other liabilities existing when the Agreement was made, where a party did not understand the nature or consequences of the Agreement, or otherwise in accordance with the ordinary law of contract. Ontario's Family Law Act sets out the grounds for setting aside a domestic contract. VERIFY the exact section number and current statutory wording before this warning, or any statement of the grounds, is treated as settled — the citation registry flags this section as unconfirmed. Complete and exchange the financial disclosure at Schedule A honestly and completely, and do not rely on this Agreement being final until each Party has had a genuine opportunity to obtain independent legal advice.

⚠️ This is a lawyer-in-the-loop document. This Agreement is not intended to be signed without each Party obtaining independent legal advice from their own lawyer, as recorded in Schedule B. It resolves matters — property, support, and parenting arrangements where applicable — that carry significant, sometimes irreversible financial and personal consequences, and that a court retains an ongoing supervisory role over (see in particular the child support note at section 6). Do not treat this template as ready to execute without that review.

THIS SEPARATION AGREEMENT is made as of [Date].

BETWEEN:

[Party A Legal Name] of [Party A Address]

("[Party A Short Name]")

— and —

[Party B Legal Name] of [Party B Address]

WHEREAS [the Parties have [Number] child(ren) of the relationship, namely [Child Name(s) and Date(s) of Birth] / the Parties have no children together — delete Part D and section 6 if so];

WHEREAS each Party has made the financial disclosure described in Schedule A and confirms it to be complete and accurate as of the date of this Agreement;

About this template

What is this template?

This is a comprehensive separation agreement for Ontario that covers property equalization, spousal support waivers, and parenting schedules. It is not a cohabitation agreement or a marriage contract for parties who are still living together. It includes specific warnings regarding the grounds for setting aside a domestic contract under the Family Law Act.

When should you use it?

Use this document when two people have separated and want to avoid litigation by settling financial and parenting matters. If the parties are still cohabitating and plan to stay together, use a cohabitation-agreement or marriage-contract instead.
