Key takeaways
  • A written agreement is signed by all parties, and an agreement about a family law dispute is generally binding, subject to the Family Law Act.
  • Filing a written agreement in court is what lets it be enforced as if it were a court order for parenting and child support.
  • A court must set aside or replace a filed parenting-arrangements agreement, in whole or in part, if it is not in the child's best interests.

You have just come out of mediation with a signed memorandum or settlement, and you may be wondering whether it actually holds. The answer depends on what the agreement covers and on whether it has been filed in court.

This article explains in plain terms how the Family Law Act treats agreements reached through mediation, what the extra steps are, and where a court can still step in. It is general information, not advice on your situation.

This article covers the law of British Columbia.

What makes an agreement binding

The Family Law Act lets two or more people make an agreement about a family law dispute, and says such an agreement is binding on the parties, subject to the Act. The Act also sets further conditions for particular kinds of agreements, so the subject matter matters.

The Act defines a written agreement as one that is in writing and signed by all parties. A mediation memorandum that everyone has signed is therefore a good starting point, but check whether it was meant to be final or only a summary of what you plan to put into a formal agreement.

Different rules for different subjects

SubjectKey point
Parenting arrangementsBinding only if made after separation, or when you are about to separate and intend it to take effect on separation
Child supportSame timing rule applies
Property and debtA witnessed agreement can be set aside only on listed grounds, or if significantly unfair
Spousal supportA witnessed agreement can be set aside on listed grounds or if significantly unfair

If you made the agreement before you were about to separate, parts of it about children may not bind you in the same way. A lawyer can confirm how this applies to your dates.

Filing it so it can be enforced

A written parenting agreement that is filed in court is enforceable as if it were a court order. A filed written child support agreement is enforceable the same way, including under the Family Maintenance Enforcement Act. A filed written spousal support agreement is also enforceable that way.

In the Supreme Court, you file a written agreement by attaching it to a requisition in Form F17.1, and the court may then enforce it on application under Part 10. A court may also incorporate all or part of a written agreement into an order, and if a later order differs from the agreement, the order replaces the part that provides differently.

When a court can still change it

Who can mediate and what happens along the way

Only a mediator qualified as a family dispute resolution professional may conduct a mediation in a family law dispute. A mediator qualifies by being a member in good standing of the Law Society of British Columbia and meeting its training and practice requirements, or by meeting other listed qualifications, which include at least 14 hours of family violence training.

A family dispute resolution professional you consult must assess whether family violence may be present. If it may be, the professional must consider how far it affects the safety of you or a family member and your ability to negotiate a fair agreement. The professional must also tell you that agreements about guardianship, parenting arrangements and contact with a child must be made in the best interests of the child only.

What to do next

Frequently asked questions

Is a verbal mediation agreement binding?

The Family Law Act says an agreement about a family law dispute is binding on the parties, subject to the Act, and it sets further conditions for particular kinds of agreements. The steps for filing an agreement in court so it can be enforced are set out for written agreements, meaning ones in writing and signed by all parties. How a verbal agreement holds up depends on your situation, so it is worth getting the terms written and signed and confirming with a lawyer.

Do I need a lawyer for the agreement to be binding?

The Family Law Act sections on agreements do not require independent legal advice for an agreement to bind the parties. Missing advice can still matter if someone later argues they did not understand the agreement or that information was not disclosed.

Can I change a mediated agreement later?

You can make a later agreement, and each changed part of the earlier agreement is revoked while the unchanged parts remain. A court can also change certain terms in the situations described above.

Do I have to disclose my finances in mediation?

A party to a family law dispute must give the other party full and true information to resolve the dispute, and that information may not be used except as necessary to resolve it.
