A separation agreement in BC does not have to be notarized, and the law does not require a lawyer to draft it. It should be in writing, signed and witnessed. Whether it holds up later depends mainly on financial disclosure, independent legal advice and fair terms, not on a stamp.

No. A separation agreement in BC does not have to be notarized, and the law does not require a lawyer to write it. What the Family Law Act looks for is simpler: an agreement in writing, signed by both of you, with each signature witnessed.
That is the form the Act looks for before it limits a court's power to rewrite a property or spousal support agreement. It is not the same as an agreement that will hold: that depends far more on disclosure, advice and fair terms than on a stamp.
The short answer: written, signed and witnessed
Under section 6 of the Family Law Act, an agreement that resolves a family law dispute is binding on the people who make it, whether or not it is ever filed in court. The Act then gives extra protection to property and spousal support agreements that are in writing, with each spouse's signature witnessed by at least one other person. The same person may witness both signatures.
The Act does not say who the witness must be. It does not ask for a notary, a lawyer or a commissioner. In practice, choose someone independent who watches each of you sign and could confirm it later. An unwitnessed written agreement is not automatically void, because the court may still decide to apply the same rules to it, but do not rely on that.
What a notary's stamp does, and what it does not
Notarizing a signature confirms who signed. It does not confirm that the terms are fair, that you both disclosed your finances, or that either of you understood what you were giving up. Those are the things a court examines if the agreement is challenged. Our guide to notary services in BC explains what notarizing a document does and does not do.
So a notarized agreement with no disclosure behind it is weaker than a plainly witnessed one where both of you exchanged full financial disclosure and had advice.
When a lawyer or notary has to be involved anyway
- Transferring the home. If the agreement moves title to land from one of you to the other, the transfer registered at the Land Title Office must be signed in front of an officer, such as a lawyer or notary public, who is not a party to it. See buying out your spouse's share of the house.
- Affidavits. If you later ask the court for a divorce or a consent order based on the agreement, the affidavits are sworn before a lawyer, notary or commissioner.
- Use outside BC. A pension administrator, bank or land registry elsewhere may ask for notarized signatures as its own condition. Ask before you sign, so that you only sign once.
Do you need a lawyer for a separation agreement?
Not by law. The Province's own guidance says a lawyer is not required to separate or divorce. The same guidance urges people to speak to a lawyer before signing anything that settles matters with a spouse.
The reason is in the set-aside rules. On a spouse's application, the Supreme Court can set aside or replace a property agreement if, when it was made, a spouse failed to disclose significant property or debts, took improper advantage of the other's vulnerability, or did not understand the nature or consequences of the agreement. Even where none of that happened, the court can step in if the agreement is significantly unfair. Similar rules apply to spousal support.
Independent legal advice for each of you is the practical answer to the argument that someone did not understand what they signed. Advice from the lawyer who prepared the agreement for your spouse is not independent, so each of you should have your own lawyer for that advice.
Templates, apps and online agreements
A form or an app can produce a document that meets the written, signed and witnessed minimum. What it cannot do is check that the support figures follow the guidelines, that the property terms say how and when each transfer happens, or that both of you have disclosed everything. Our guide to DIY separation agreement mistakes covers seven common gaps.
After you sign: filing and deadlines
A written agreement about parenting arrangements, child support or spousal support that is filed in court is enforceable as if it were a court order. Filing is optional, but it saves a step if payments stop. Our guide to enforcing a separation agreement explains how.
Two timing rules are worth knowing. Agreements about parenting arrangements and child support are binding only if they are made after separation, or when you are about to separate. And a spouse who wants a court to set aside a property or spousal support agreement has two years from when they discovered, or reasonably ought to have discovered, the grounds.
Terms about children are never final in the same way. A court can replace child support terms if it would have ordered something different, and parenting terms that are not in the child's best interests.
What a lawyer actually does on a separation agreement
Legal help with a separation agreement is a defined piece of work. Ask at the outset which of these you need; many people need only the first.
- Review and independent legal advice. The lawyer reads the draft and the disclosure behind it, explains what you are agreeing to and what the Act would otherwise provide, and confirms in writing that you were advised.
- Drafting. Turning what you have agreed, whether at the kitchen table or in mediation, into terms that can be carried out: who transfers what, by when, and what happens if it is not done.
- Completing it. Filing the agreement, preparing the transfer of the home, and, if you are married, the desk order divorce that usually follows.
