✓ You will need to bring valid photo identification. The identification must show your photo, your full name, and signature.
X Do not sign the document before arriving. The document(s) to be commissioned must be signed in the presence of a Commissioner of Oaths.

Your responsibility
If you are signing a legal document that requires your oath, affirmation, or declaration, the content of that document is your sole responsibility. When you are making an oath, you are known as the "deponent" –the person whose signature is being commissioned to ensure the content of the affidavit. As a deponent, you must understand the details in the document to which you are attesting– and you must understand that, by swearing an oath, you are attesting that those details are correct.
We do not provide the services of a Notary Public
A Notary Public is a person authorized by the Notaries Act to commission documents, certify or notarize documents as true copies, and to verify signatures. The requirements to become a Notary Public are stricter than for a commissioner and a Commissioner cannot sign on behalf of a Notary Public.
