If you have ever been asked to sign a document before a notary or commissioner for oaths, you may have encountered the terms affidavit and statutory declaration. Although these documents appear similar, they serve distinct purposes under Alberta law and are used in different legal contexts.
This guide from the Notarial Services team at Libra Law explains what each document is, how they differ, and when you might need one.
An affidavit is a written statement of facts that you swear to be true before a commissioner for oaths or a notary public. The key feature of an affidavit is that it involves an oath or affirmation, which means the person signing is making a legally binding promise to tell the truth.
Affidavits are often used in legal proceedings such as court cases, immigration applications, and business transactions. Common examples include:
Because an affidavit carries the same weight as oral testimony in court, knowingly making a false statement can lead to charges of perjury under the Criminal Code of Canada.
A statutory declaration is also a written statement of facts, but it does not involve an oath or religious affirmation. Instead, you declare that the information provided is true to the best of your knowledge.
Statutory declarations are commonly used in non-court settings where an official confirmation is required but no legal proceeding is involved. Examples include:
Unlike affidavits, statutory declarations are governed by the Canada Evidence Act and Alberta’s Evidence Act, depending on the document’s purpose and where it will be used.
Although both documents serve to confirm facts, the key differences lie in their formality and use.
An affidavit is sworn under oath, meaning the person signing promises before a commissioner or notary that their statement is true. This is typically required in court-related or formal legal proceedings.
A statutory declaration, on the other hand, does not include an oath. It is a simple declaration of truth used primarily for administrative, business, or government matters where no court involvement is necessary.
In both cases, the signature must be witnessed by an authorized person such as a notary public or commissioner for oaths in Calgary to make the document legally valid.
