When dealing with legal documents, affidavits, or statutory declarations, you may come across the term Commissioner for Oaths. But what exactly does this role entail, and when might you need one?
In this post, we’ll break down the responsibilities of a Commissioner for Oaths and how they can assist you in ensuring your documents are properly prepared and verified, ensuring that your documents are legally valid and accepted by courts, government agencies, and other institutions.
What is a Commissioner for Oaths?
A Commissioner for Oaths is a person appointed by the Ministry of Justice that is authorized to administer oaths and take and receive affidavits, affirmations, and declarations in and for Alberta. They play a crucial role in ensuring that written statements are legally valid and truthful.
They do not provide legal advice or act as a Notary Public (although in some regions, these roles may overlap), but they do ensure that the person signing a document understands the contents and swears or affirms that the information is accurate to the best of their knowledge. This process helps prevent fraud and ensures that the statements made in the documents are truthful.
Using a Commissioner for Oaths guarantees that your documents meet legal standards and can be confidently submitted to the relevant authorities.

When Might You Need a Commissioner for Oaths?
You may need the services of a Commissioner for Oaths in the following situations:
Swearing an affidavit (for court proceedings, immigration applications, etc.)
Signing a statutory declaration (such as change of name declarations)
Completing legal documents
Administering oaths or affirmations
The Commissioner will review your documents, confirm your identity, and witness your signature. They will then apply their official seal or stamp to certify the document.
What Does the Process Involve?
The process is typically quick and straightforward:
You bring your document(s) and valid photo identification.
You affirm or swear the truthfulness of the content in the presence of the Commissioner.
The Commissioner witnesses your signature and completes their section of the document, including their seal or stamp where applicable.
It’s essential that you do not sign the document before arriving, as it must be signed in front of the Commissioner.
