What is collaborative divorce and how does it work in Ontario?

TSL Written by the Treadstone Law team· Updated June 2026

Collaborative divorce is a structured dispute resolution process in which both spouses and their lawyers commit in writing to resolving all issues without going to court. Each spouse has their own collaboratively trained lawyer, and the four parties meet together in a series of "four-way meetings" to work through parenting, support, and property issues.

The defining feature of the collaborative process is the participation agreement signed at the outset: if either party decides to abandon the process and go to court, both lawyers must withdraw and cannot represent their clients in litigation. This creates a strong incentive for everyone — lawyers and clients alike — to work toward settlement.

Collaborative divorce often brings in other professionals as needed: a financial specialist can help model different division scenarios; a family specialist (sometimes a psychologist) can help manage communication and child-focused discussions. This interdisciplinary approach addresses not just the legal but also the emotional and financial dimensions of separation.

Not every case is suitable for collaborative divorce — it requires both spouses to engage in good faith and there should not be a serious power imbalance or safety concern. When it works, it typically produces more creative, durable agreements than court orders and preserves the co-parenting relationship better than adversarial proceedings.

Key takeaways

  • Collaborative divorce is a structured, out-of-court process with each spouse having their own trained lawyer.
  • Both parties sign a participation agreement committing to stay out of court.
  • Financial and family specialists are often brought in alongside the lawyers.
  • It works best where both spouses are willing to engage in good faith.
This is general information, not legal advice. It doesn’t create a lawyer–client relationship, and the rules can change. For advice on your situation, a Treadstone family lawyer can help.
