Can We Agree on Spousal Support in a Separation Agreement Without Going to Court in Ontario?

TSL Written by the Treadstone Law Team· Updated November 6, 2026

Yes. Couples can agree on spousal support in a separation agreement, or have a judge decide. Going to court is not required to settle the amount. The amount depends on factors such as the income gap, who cared for any children, each person's age, roles during the relationship, health, and ability to support themselves.

Many people use the Spousal Support Advisory Guidelines as a starting point. They are not law, but judges often base their decisions on them. They do not decide entitlement, which must be established first, and an income gap alone does not create it. Entitlement can also be contractual, arising from a formal domestic contract.

Enforcement and tax need planning. FRO does not receive a separation agreement automatically; it must be filed with a court and then registered with FRO before FRO can enforce it. For tax, the agreement must clearly state the spousal amount for the payments to be deductible and taxable, and child support must be fully paid. Only a court can change a support order. Independent legal advice and the rules for challenging an agreement later depend on your facts, so speak with a lawyer before you sign.

Key takeaways
