Acceptance of Authority to Adjudicate a Dispute
Last Updated: August 28 2026
Question: How does attornment of jurisdiction affect where my legal dispute is heard in Ontario?
Answer: Attornment of jurisdiction means a party agrees, accepts, or submits to a specific court or tribunal (or arbitration) so the case proceeds in that forum even if it might otherwise be contested. In Ontario, it commonly happens through a contract forum selection clause, a later written consent, or by conduct such as participating in proceedings without raising a timely jurisdiction objection, and it can affect procedure, timelines, and strategy.

Attornment to jurisdiction may occur through several distinct avenues, each with its own legal considerations. The most straightforward method is by contract, where a forum selection clause in an agreement specifies the court or tribunal that will decide any disputes, often naming a particular province, city, or county. Alternatively, parties may attorn through a written agreement made after a dispute has arisen, formalizing consent to have the matter heard in a specific forum. Attornment can also arise by conduct, such as when a party participates in proceedings without raising a timely objection to jurisdiction, thereby implicitly accepting the authority of the forum. Each of these scenarios involves unique strategic and procedural implications, warranting separate and detailed examination.
