A template from the internet, two signatures at a kitchen table, and a relieved handshake: this is how many Ontario couples believe they have dealt with the end of their relationship. Sometimes a document like that will hold up. Sometimes it will fall apart the first time someone tests it, often at the point when a parent has a new job, a house has gone up in value, or someone wants to remarry.
A separation agreement is a private contract between two people who have separated. It can settle almost everything a family court would otherwise be asked to decide, and it can do so with less cost and more control than a court process. It is also a legal document with long-lasting consequences. It deserves far more care than most people assume they have to give it.
Nothing here is legal advice. This article provides general information about agreements in Ontario, and whether a specific term suits your family depends on your circumstances.
The legal rules that make one valid
Separation agreements are governed mainly by Part IV of Ontario’s Family Law Act, which deals with domestic contracts. Under section 54, two people who cohabited and are living separate and apart may agree on their rights and obligations, including ownership and division of property, support, decision-making responsibility and parenting time.
Section 55 sets the formal requirements. To be enforceable, the agreement must be:
- in writing
- signed by both parties
- witnessed
The witness requirement trips people up surprisingly often. An exchange of text messages or an email saying “agreed” will not satisfy this standard for a domestic contract, although a court has some flexibility in the unusual case. Have each signature witnessed by an adult who is not a party, and have the witness sign as well.
Unmarried couples can use a separation agreement too. In fact, it may be even more useful for them, because the statutory equalization scheme does not apply to common-law partners. Without an agreement they may be left with the title to the property and with more complicated claims.
What belongs in the document
No two agreements look the same, but a thorough one usually deals with the following topics.
The basics. Full legal names, dates of birth, children’s names and birth dates, the date of marriage or when cohabitation began, and the date of separation. Getting the separation date right matters, as it often becomes the valuation date for property. If you disagree on the date, resolve this before you sign.
Parenting. Decision-making responsibility on major matters such as health, education, culture and religion, along with a parenting-time schedule that covers weekends, holidays, school breaks and how the handoffs work. Many agreements also include a process for travel consent and how to communicate. Our guide to parenting arrangements and custody describes the terms used under current Ontario and federal law.
Child support. The payor’s income, the guideline table amount, each parent’s share of special or extraordinary expenses under section 7, how often incomes are to be exchanged and how adjustments will be made, and when support is to end.
Spousal support. The amount, when it starts and ends, the circumstances in which it can be reviewed, or a clear statement that neither of you is seeking it. If support is waived or fixed, say so directly and explain the context.
Property. Each spouse’s net family property, any equalization payment, who keeps which assets and debts, and how and when the transfer will occur. If one person is keeping the home, cover how the mortgage will be refinanced and what happens if refinancing fails. If it is being sold, state who pays carrying costs in the meantime and how the proceeds will be split.
Pensions and registered plans. Whether a pension is being divided or balanced off in another way, and the steps needed to do so. Transfers often require the plan administrator’s forms and specific wording.
Insurance. Whether life insurance will secure support obligations, and whether children stay on a health plan.
Releases. A clear statement of which claims are being given up, and which are not.
Disclosure. A recital that each party has provided financial disclosure, with the financial statements attached or listed.
Independent legal advice. A statement confirming whether each party has had it, ideally supported by certificates signed by the lawyers.
Dispute resolution and change. What you will do if circumstances change, or a disagreement comes up: negotiation, mediation, arbitration or a motion to change.
Divorce. If you plan to divorce later, whether one of you will file and who pays. An agreement does not, by itself, end a marriage.
What to avoid
Agreements most often go wrong in the same recognizable ways. Watch for these.
Hidden or vague finances
Section 56(4) of the Family Law Act lets a court set aside an agreement or a provision if a party failed to disclose significant assets, debts or other liabilities that existed when the agreement was made, did not understand the nature or consequences of the agreement, or on other grounds available under contract law, such as duress. A lack of disclosure can undo work you thought was finished, even when the other person acted in good faith at the time. Get the numbers in writing.
A promise to waive child support
Child support belongs to the child’s interests, and parents cannot simply contract out of it. A court may disregard a child support term that is unreasonable having regard to the child support guidelines, even if both parents happily signed it. The same is true for parenting: under section 56(1), a court may disregard a term dealing with decision-making responsibility or parenting time where doing so is in the child’s best interests. A clause saying “the father gives up all contact in exchange for no support,” for example, should not be relied upon.
Pressure and a rushed signature
Agreements signed under pressure, with one party scrambling and no time to get advice, are more likely to be challenged, and they are less likely to work in practice. A person should have a chance to read a draft, get advice and propose changes. If someone is threatening you, or if there is abuse in the relationship, speak to a lawyer privately before negotiating at all.
Copying a template without understanding it
Generic online agreements often use out-of-date terms like “custody” and “access,” or they rely on rules from another province or from the United States. Ontario’s law uses the terms “decision-making responsibility” and “parenting time” for most parents. An outdated word will not void a contract, but a clause copied from elsewhere may leave a real gap.
Language that sounds clear but is not
“Parenting time will be flexible.” “Support will be reviewed when appropriate.” “The parties will share costs fairly.” These terms may feel friendly in the moment, but they tend to create disputes. Ask yourself how each clause would work if you and the other person were no longer on good terms. Specific dates, amounts and procedures usually age better.
Ignoring tax and title
A home transfer can involve land transfer or mortgage consequences. Periodic spousal support and child support are treated differently for tax purposes, and a lump sum may be treated differently again. Transferring an RRSP without the proper process could trigger tax. Get accurate advice on the after-tax effect of your deal, since the headline number can mislead.
Assuming the deal covers everything forever
A broad release can be useful, but make sure you understand what it gives up, including possible claims to support or to a former spouse’s pension. Courts may, in some situations, override a support waiver. Section 33(4) of the Family Law Act allows it, for instance, where the provision results in unconscionable circumstances. Conversely, do not count on a court rescuing you from a poor bargain. Treat the release as final when deciding to sign.
The role of independent legal advice
Ontario law does not require a lawyer for a valid separation agreement. But having each person advised by their own lawyer is one of the strongest protections available. That lawyer can explain what you would likely be entitled to, what you are giving up and what the words mean, and can confirm that you understood and signed freely. This makes it harder for either person to later say they did not understand the deal.
One lawyer cannot usually act for both spouses in this kind of negotiation, since their interests differ. Even when things are amicable, plan for each person to have their own advice. If money is tight, ask about limited-scope help, where a lawyer reviews a draft and provides advice for a set fee.
After you sign
A signed agreement is a beginning. Some practical follow-up usually needs to happen:
- File it, if you want it enforced as an order would be. Under section 35 of the Family Law Act, either party can file a domestic contract with the Ontario Court of Justice or the Family Court of the Superior Court, with an affidavit. Support provisions may then be enforced as if they were a court order. Ontario’s guidance points to Form 26B for this purpose, and the clerk at the Brampton courthouse can tell you how to submit it.
- Consider the Family Responsibility Office. Once a written agreement has been filed with a court, it can be registered with this provincial office, which collects and enforces support. Enforcement tools can include reporting to credit bureaus and suspending certain licences.
- Carry out the property steps. Transfer title, close joint accounts, submit pension forms and change beneficiary designations as agreed.
- Update your will and your powers of attorney. A separation agreement may not automatically change them.
- Calendar each review date. Annual income exchanges and review clauses have no effect if nobody remembers them.
If circumstances change significantly later, you might agree to amend the document in writing, signed and witnessed like the original. Otherwise, a motion to change may be available under Rule 15 of the Family Law Rules for support provisions in a filed agreement, and parenting terms remain subject to the child’s best interests.
Building one that lasts
A strong agreement reflects the actual lives of the people signing it. Before you start, gather your financial documents, write out a realistic weekly schedule for the children, and think through how your needs may change in the next few years. If your family works on shifts, or a parent commutes from Brampton to Toronto or Pearson, write the parenting schedule around those facts rather than around an ideal week.
If you would like a lawyer to draft your agreement or review one you have been given, our family law practice handles this kind of work. An hour of review before signing is far less expensive than trying to set aside a signed agreement later.
