Separation Agreement Lawyer in Brampton, ON
A separation agreement lets you settle property, support and parenting without a judge deciding for you. Done properly it is binding and enforceable. Done carelessly it can be set aside years later, usually at the worst possible moment.

Separation Agreements, explained

What Is a Separation Agreement?
A separation agreement is a domestic contract under Part IV of Ontario's Family Law Act. Two people who have cohabited and are living separately can agree on their respective rights and obligations — property division, spousal support, child support, parenting arrangements and any other matter in settlement of their affairs.
You do not need to be divorced, or even to have started a court proceeding, to have one. Many separating couples resolve everything by agreement and only later obtain a divorce, which is a separate step.
An agreement is generally faster, cheaper and more private than litigation, and it leaves the decisions with the two people involved rather than a judge who will never know the family.

What Makes a Separation Agreement Legally Binding?
Section 55(1) of the Family Law Act is strict: a domestic contract, and any agreement to amend or rescind one, is unenforceable unless it is made in writing, signed by the parties and witnessed.
All three requirements matter. A verbal agreement is not enforceable as a domestic contract. Neither is an exchange of text messages, an unsigned draft, or a signed document with no witness. Agreements fail on these formalities more often than people expect.
Beyond form, three things make an agreement durable in substance: complete and honest financial disclosure by both parties, independent legal advice for each of them, and terms that are not so one-sided as to be unconscionable. Each of those is a recognised ground of attack when missing.

When Can a Separation Agreement Be Set Aside?
Section 56(4) of the Family Law Act allows a court to set aside a domestic contract or a provision in it on defined grounds, including where a party failed to disclose significant assets, debts or other liabilities existing when the contract was made, where a party did not understand the nature or consequences of the contract, or otherwise in accordance with the law of contract.
Two further limits apply regardless of what the agreement says. Section 56(1) allows the court to disregard any provision about a child's education, moral training, decision-making responsibility or parenting time where doing so is in the child's best interests. And section 33(4) allows a support provision or waiver to be set aside in the circumstances described on our spousal support page.
The practical lesson is that you cannot contract out of a child's best interests, and you cannot make a support waiver unassailable. What you can do is make an agreement that stands up, by disclosing fully and making sure both parties genuinely understood what they signed.

Why Does Each Party Need Independent Legal Advice?
Because the most common way an agreement is attacked is the argument that one party did not understand it, or was pressured into it. Independent legal advice is the single most effective answer to that argument.
One lawyer cannot advise both parties. The interests are opposed, and a lawyer who acted for both would be in a conflict. The usual course is that one party's lawyer prepares the draft and the other party takes it to their own lawyer for advice before signing.
A party who chooses not to get advice can still sign, but the agreement is weaker for it — and it is weaker against the person who insisted on skipping the step, not in their favour.

What Should a Separation Agreement Cover?
An agreement that is silent on something contentious has not avoided the problem; it has deferred it. See our pages on equalization of property, child custody and domestic contracts.

How Is a Separation Agreement Different From a Divorce?
They do different things. A separation agreement resolves the financial and parenting consequences of the relationship ending. A divorce legally ends the marriage itself and is granted by the court under the federal Divorce Act.
You can have an agreement without a divorce, and you can be divorced without ever having had an agreement. Most people who were married do both — settle by agreement, then obtain the divorce as an administrative step.
For unmarried couples there is no divorce to obtain. A separation agreement is the whole of the resolution, which is part of why getting it right matters even more.
