Key takeaways
  • In family mediation, the mediator is a neutral third party who does not take sides, make decisions or give legal advice, and taking part is voluntary.
  • Mediation-arbitration needs both parties' agreement, and the arbitration result is binding and enforceable by the court.
  • Appeals of family arbitrations are heard in the Superior Court of Justice, so ask a lawyer about appeal rights before you sign anything.

When you and your former partner cannot agree, court is not your only route. Some people choose mediation, which can be used before, during or instead of a court case and can be faster, cheaper and more private than court.

Before you agree, it helps to know how arbitration differs from mediation and court, what happens if you are unhappy with the result, and which rules apply. This article gives the general picture for Ontario and points out where you need advice on your own situation.

What arbitration is, in plain words

In arbitration, you and the other party agree to have an arbitrator decide the issues instead of a judge. The arbitrator listens to each side, looks at the evidence and the law, and gives a decision. That is the key difference from mediation, where the mediator is a neutral third party who does not take sides, make decisions or give legal advice.

Arbitration is not the same as negotiation or collaborative law. Ontario describes collaborative family law as a process where both parties and their lawyers agree not to go to court.

How it compares with mediation and court

Ontario says mediation can be used before, during or instead of a court case and can be faster, cheaper and more private than court. Whether arbitration saves you time or money depends on the arbitrator, the issues and how much you disagree, so it is worth asking about costs up front.

Mediation-arbitration and what binding means

Some people use a combined process called mediation-arbitration. It requires both parties' agreement, and the arbitration result is binding and enforceable by the court.

Binding is the point to think about most carefully. How a binding result would affect your options later depends on your situation, so it is worth confirming before you sign anything. Ask a lawyer what you would be agreeing to, and what safeguards you want in the written agreement.

If there has been family violence or a power imbalance, arbitration may not suit you. Mediators screen each person separately to confirm an equal negotiating position, and the screening continues throughout. Divorce Act duties also recognize that family dispute resolution may clearly not be appropriate, for example where there is family violence.

Appeals, court involvement and the rules

The Superior Court of Justice hears family arbitration appeals. The grounds and time limits for an appeal depend on the arbitration agreement and the governing legislation, so confirm them with a lawyer before you agree to arbitrate rather than after you receive a decision.

A case that involves only family arbitration is one of the situations where you do not need to attend the Mandatory Information Program. Parties to a Divorce Act proceeding must still try to resolve matters through a family dispute resolution process to the extent it is appropriate.

Frequently asked questions

Is family arbitration the same as mediation?

No. Some people combine them in mediation-arbitration, which needs both parties' agreement.

Can I be forced into mediation-arbitration?

Mediation-arbitration requires both parties' agreement, and the arbitration result is binding and enforceable by the court. Whether you could be held to an earlier written agreement to arbitrate depends on what it says, so have a lawyer review it.

Can I appeal an arbitrator's decision?

Family arbitration appeals are heard in the Superior Court of Justice. Whether you can appeal, and on what grounds, depends on your agreement and the law, so get advice early.

Do I need to attend the Mandatory Information Program if I use arbitration?

A case that involves only family arbitration is one of the exceptions. If your court case includes other issues, the program may still apply, so check with the court or a lawyer.
