Third Party Affidavit Template for Canada

When you need sworn testimony from someone who isn't directly involved in your legal matter, a Third Party Affidavit provides the formal mechanism to obtain and present that evidence. This legal document allows individuals with relevant knowledge, expertise, or information to provide sworn statements that can be used in various legal proceedings across Canada.

When do you need this document?

You'll require a Third Party Affidavit when seeking evidence from witnesses, experts, or other individuals who have relevant information but aren't parties to your legal matter. Common situations include obtaining witness statements for personal injury cases, securing expert testimony for business disputes, gathering evidence from former employees in employment matters, or collecting statements from neighbors in property disputes. The document is also essential when you need to present technical evidence through expert witnesses or when court rules require sworn testimony rather than simple witness statements.

Key legal considerations

The deponent must have personal knowledge of the facts they're swearing to, as hearsay evidence is generally inadmissible unless it falls under specific exceptions. You must ensure the affidavit includes clear identification of the deponent, their basis of knowledge, and organized factual statements in numbered paragraphs. The document requires proper execution before an authorized commissioner of oaths or notary public, and false statements can result in perjury charges under Section 131 of the Criminal Code of Canada. Consider whether supporting exhibits are necessary and ensure they're properly referenced and attached. The timing of obtaining the affidavit is crucial, as witness memories fade and availability may change.

Legal requirements in Canada

Under the Canada Evidence Act and provincial evidence legislation, Third Party Affidavits must meet specific formal requirements to be admissible in court. The document must include the style of cause if part of legal proceedings, complete deponent information including full legal name and address, and a clear statement of the deponent's basis of knowledge. Provincial Rules of Civil Procedure govern the format and content requirements, which may vary between provinces. The affidavit must be sworn or affirmed before someone authorized under provincial Commissioners for Taking Affidavits Acts or Notaries Acts. If the deponent doesn't speak English or French fluently, you may need certified translation services and an interpreter present during swearing. Some provinces have specific requirements for the jurat clause and the commissioner's seal or stamp.
