Key takeaways
  • A separation agreement is not a divorce, and only a court can grant a divorce.
  • The Family Responsibility Office (FRO) enforces a separation agreement only if it is registered with the court using form 26B.
  • Support wording that looks harmless, such as indexing or "in accordance with the guidelines", can leave FRO unable to enforce it.
  • A support agreement made without full, honest financial disclosure can be set aside by a court.

A free template can look like a quick way to put a separation on paper. Many of them are short and generic. They tend to cover the headings, such as property, support and children, without the detail that makes terms workable once real life starts.

This article explains what a generic form commonly leaves out and where agreements run into trouble later. It is general information, not advice on your situation. If your family has children, a home, a business or a pension, it is worth having a lawyer read the draft before you sign.

What a separation agreement does and does not do

A separation agreement is one of five kinds of domestic contract. It sets out how you and your spouse have agreed to handle money, property, support and children after you separate. It is not a divorce. The Divorce Act does not require one, and only a court can grant a divorce.

Ontario.ca notes that separation agreements let spouses divide property as they choose, that each spouse should have their own lawyer review the agreement, and that it is hard to change later. That last point is why gaps matter. A template you sign today may be difficult to fix next year.

Common gaps in free templates

Every family is different, so no template can know your facts. These are the areas where generic forms are most often thin.

None of these gaps is fatal on its own, but each one is a place where a later dispute can start.

Support wording that can fail

Ontario drafting guidance warns against several phrases that sound reasonable but cause problems. It says to set special expenses either as a fixed amount or as expenses the recipient claims on a sworn statement of arrears, to use the word "pay" rather than "share", and that FRO may be unable to enforce special expenses that are not set out this way.

The same guidance says cost-of-living (indexing) clauses are not permitted for child support and FRO cannot enforce them. It also warns against wording that says child support changes each year "in accordance with the Child Support Guidelines", because FRO cannot recalculate support that way and may be unable to collect it.

A good alternative is a yearly exchange of income information. The guidance gives an example requiring both parties to send updated income disclosure within 30 days of the order's anniversary. The Guidelines themselves let a spouse request updated income documents in writing, not more than once a year after the order is made.

When an agreement may not hold up

Ontario.ca says a spousal support agreement should be made with full, honest financial disclosure, without pressure, and with an understanding of its terms. Otherwise a court can set it aside. Whether those conditions are met depends on how the agreement is actually made, not on the form itself, so it is worth confirming with a lawyer.

Enforcement is a separate issue. FRO enforces a separation agreement only if it is registered. You file it with the Ontario Court of Justice or the Superior Court of Justice using form 26B, then send FRO the contract, the court-signed 26B and a completed FRO registration package.

Whether a signature, witness or other formality is missing is a question of the Family Law Act. A lawyer can confirm the requirements for your agreement, so do not assume that a signed template is automatically valid.

Changing an agreement later

Only a court can change a support order or domestic contract. To change a domestic contract, the parties negotiate a new contract and file it with the court using form 26B. FRO cannot change the terms.

If you both agree to change support, you can file a consent motion. If not, one of you files a motion to change, and the other has 30 days to respond, or 60 if they are outside Canada or the U.S.. A spousal support agreement may also include a review date, and may end support on events such as remarriage or retirement.

What to do next

Frequently asked questions

Is a separation agreement the same as a divorce?

No. A separation agreement is a private contract, and the Divorce Act does not require one. Only a court can grant a divorce.

Can I use the template if we agree on everything?

You can use it as a starting point, but agreeing is not the same as drafting it well. Support wording, disclosure and enforcement details can cause trouble even when both spouses are cooperative. Ontario.ca recommends that each spouse have their own lawyer review the agreement.

Will FRO collect support under my signed template?

Only if the agreement is registered. That means filing it with the court using form 26B and sending FRO the contract, the signed 26B and the registration package.

What if we later want different terms?

You would generally negotiate a new contract and file it with the court using form 26B, because FRO cannot change the terms. If you cannot agree, a motion to change is the route.
