What a separation agreement in Ontario usually covers

A separation agreement is a written contract between two people who have separated or are about to separate. It can be used by married spouses and by common-law partners. Most agreements deal with some or all of the following: parenting time and decision-making responsibility for children, child support, spousal support, the division of property and debts, what happens to the family home, and how future disagreements will be handled. Not every agreement needs every section; the content depends on your circumstances.

Is a separation agreement legally binding in Ontario?

A separation agreement can be legally binding in Ontario. Under the Family Law Act, a domestic contract must be in writing, signed by both people, and witnessed. Once properly made, it can be enforced like any other contract, and its support terms can be filed with the court so that they can be enforced through the Family Responsibility Office.

A court can set aside all or part of an agreement in some situations, for example where one person did not disclose significant assets or debts when the agreement was made, where one person did not understand the nature or consequences of the agreement, or where the agreement would not otherwise be upheld under the general law of contract. Terms about children can also be revisited where that is in the best interests of the child. This is why full financial disclosure and independent legal advice for each person are commonly recommended: they make an agreement much harder to challenge later.

Do I need independent legal advice before signing?

Ontario law does not always require each person to have a lawyer, but independent legal advice is strongly recommended and is often expected before an agreement is signed. It means each person receives advice from a lawyer acting only for them, so both people understand their rights, what they are agreeing to, and what they may be giving up. Mida Law can provide independent legal advice on an agreement prepared by another lawyer, or draft an agreement for you and explain its terms.

Reviewing an agreement you have been given

If your former partner or their lawyer has sent you a draft, it is reasonable to have it reviewed before you sign. A review looks at whether the agreement reflects what you actually agreed to, whether the financial disclosure is complete, how support has been calculated, and what the agreement says about changing the terms later. We explain the agreement in plain language and tell you where questions remain, so you can decide with confidence.

Separation agreements and divorce

A separation agreement is not the same as a divorce. Separated spouses can settle parenting, support and property in an agreement without applying for a divorce, and many people do. A divorce is a court order that formally ends a marriage. If you later apply for a divorce, a well-drafted separation agreement usually makes the process simpler because the main issues are already settled. Our article on separation versus divorce in Ontario explains the difference in more detail.
