Key takeaways
  • In collaborative family law each person has their own lawyer and everyone agrees not to go to court, while in mediation a neutral mediator helps you reach agreement.
  • If a collaborative process fails, each person needs a new lawyer to go to court, so the risk of starting over is real.
  • Some types of dispute resolution may not be appropriate where there is family violence or a power imbalance.

You and your spouse or partner have decided to separate and you would both like to avoid a court fight. Two options come up again and again: collaborative family law and mediation. They sound similar, but they work differently and carry different risks.

This article explains the difference in plain words, what each approach asks of you, and when neither may be a good fit. It is general information for Ontario, not advice for your situation.

How each process works

Collaborative family law means each party works with their own lawyer to reach an agreement, and everyone agrees not to go to court. The lawyers are there to help you settle, not to prepare for a trial.

In mediation, a neutral mediator helps the parties reach agreement but does not take sides, make decisions or give legal advice. You and the other person remain the ones who decide the outcome.

Risks and drawbacks to weigh

The biggest risk in the collaborative approach is the agreement not to go to court. If there is no agreement, each party needs a new lawyer to go to court. That can mean repeating work and starting over, so it is worth asking early how you would feel about that.

The main risk in mediation is that the mediator will not give you legal advice. You may agree to something without knowing whether it is fair. Many people get their own legal advice before and after mediation for that reason.

The law encourages settlement, but not at any cost

Under the Divorce Act, to the extent appropriate, the parties to a proceeding must try to resolve their matters through a family dispute resolution process. Legal advisers must encourage this unless the circumstances make it clearly inappropriate.

There is an important exception. Justice Canada notes that some types of dispute resolution may not be appropriate in high-conflict cases or where there is a power imbalance or family violence. Ontario mediators screen for intimate partner violence at intake and throughout the process. If you feel unsafe or unable to speak freely, tell the mediator or your lawyer, and ask about safer options.

What to do next

A family lawyer can explain which approach fits your facts, and can review any agreement before you sign it.

Frequently asked questions

Can a mediator tell me what is fair?

No. A mediator is neutral and does not take sides, make decisions or give legal advice. If you want to know whether a proposal is fair, speak with your own lawyer.

Can I still go to court if collaborative law does not work?

Yes, but not with the same lawyer. Everyone agrees not to go to court in a collaborative process, and if there is no agreement each party needs a new lawyer to go to court.

Do I have to try dispute resolution before going to court?

Under the Divorce Act, parties must try to resolve their matters through a family dispute resolution process to the extent appropriate. Legal advisers must encourage it unless the circumstances make it clearly inappropriate.

Is mediation safe if there was abuse?

It may not be. Some types of dispute resolution may not be appropriate where there is family violence or a power imbalance. Ontario mediators screen for intimate partner violence at intake and throughout the process.
