Key takeaways
  • A separation agreement does not have to be filed or registered with a court to be binding in British Columbia.
  • Filing a written child support, spousal support or parenting agreement lets it be enforced like a court order.
  • Even a filed agreement can be set aside or replaced in some situations, so getting independent legal advice before signing matters.

You and your spouse have worked out how to handle parenting, support or property after separating, and you have put it in writing. Now you are wondering whether the agreement has to go to a court before it counts.

The short answer is that filing is usually optional, but it can change how easily the agreement is enforced. This article explains the difference, how filing works, and the limits that apply either way.

This article covers the law of British Columbia.

Is filing required for the agreement to be binding?

No. A separation agreement does not have to be filed or registered with a court to be binding. You also do not need a lawyer to make an agreement, although the government strongly encourages getting advice first.

So an unfiled agreement still matters. The question is what happens if one person stops following it, and that is where filing can help.

Why you might file it anyway

A written agreement about child support or spousal support that is filed in the court is enforceable under the Family Law Act like a court order. The same is true of a written agreement about parenting arrangements that is filed in court.

A filed support agreement can also be enforced through the Family Maintenance Enforcement Program.

Type of agreementEffect of filing
Child supportEnforceable like a court order
Spousal supportEnforceable like a court order, and can use the Family Maintenance Enforcement Program
Parenting arrangementsEnforceable as if it were a court order

How to file

Written agreements on parenting time, contact, child support and spousal support can be filed at a court registry. The Provincial Court Form 26 is the request to file an agreement.

Registry staff can tell you how their process works in practice. If you are unsure which agreement or which court is involved, a lawyer can confirm before you file.

The limits, even when an agreement is filed

The property rules apply to a written agreement with each spouse's signature witnessed by at least one other person. The same person may witness both signatures.

A spouse can apply to set aside a property or spousal support agreement within 2 years after first discovering, or reasonably ought to have discovered, the grounds.

What to do next

The government says it is very important to speak to a lawyer before signing a document that settles matters with a spouse.

Frequently asked questions

Can I rely on a separation agreement I never filed?

Yes, it can still be binding, because filing or registering is not required. Filing matters mainly for enforcement of child support, spousal support and parenting terms.

Does filing a support agreement help with collecting payments?

A filed support agreement can be enforced through the Family Maintenance Enforcement Program. It is also enforceable like a court order.

Can a court change a filed parenting agreement?

Yes. If it is not in the child's best interests, the court must set aside or replace all or part of it with an order.

How long do I have to challenge a property agreement?

A spouse can apply to set aside a property or spousal support agreement within 2 years after first discovering, or reasonably ought to have discovered, the grounds. Time stops running during family dispute resolution or a prescribed process.
