An affidavit can look like ordinary paperwork, but one missing signature, an unsigned exhibit, or signing too early can cause a filing to be rejected. Knowing how to commission an affidavit helps you get it done correctly the first time, whether the document is for court, an insurance claim, an estate matter, a real estate file, or a government application.
In Alberta and other Canadian jurisdictions, an affidavit is generally sworn or affirmed in front of a commissioner for oaths, notary public, or another authorized official. The official does not confirm that every statement is true. Their role is to verify your identity, make sure you understand the oath or affirmation, witness your signature, and complete the required jurat or certificate.
What it means to commission an affidavit
To commission an affidavit means to formally swear or affirm that its contents are true before an authorized official. You then sign the affidavit while that person watches. The commissioner signs and dates it, and applies their stamp or seal where required.
A sworn affidavit includes an oath, which is a solemn promise made before God or according to a religious belief. An affirmation has the same legal effect but does not include a religious element. You can choose the option that is appropriate for you.
The wording on the document matters. An affidavit usually begins by identifying the person making it, often called the deponent or affiant, and ends with a section stating where and when it was sworn or affirmed. That final section must be completed accurately by the commissioner.
Before you book: make sure the document is ready
The fastest appointment is the one where the affidavit is complete before you arrive. Read the document carefully, confirm that names and dates are correct, and make sure every page that needs to be attached is present.
Do not sign the affidavit in advance. Your signature must be witnessed by the commissioner or notary. If you have already signed it, you may need to prepare a fresh copy and sign again during the appointment.
If the affidavit refers to attachments, exhibits, or schedules, bring them with you. For example, an affidavit may refer to a copy of a contract, photo, bank statement, or letter. The commissioner may need to mark or identify these pages as exhibits. Leaving them out can create a problem later, especially if the affidavit will be filed with a court or submitted to an organization with strict requirements.
If a lawyer, court clerk, employer, insurer, or government office gave you the form, follow their instructions exactly. Some organizations require a specific form, particular wording, or a notary public rather than a commissioner for oaths. Ask the receiving organization before your appointment if you are unsure.
What to bring to an affidavit appointment
Bring the original unsigned affidavit and all supporting pages. You should also bring valid, government-issued photo identification, such as a driver’s license or passport. The name on your ID should match the name on the affidavit. If it does not, bring supporting documentation if available, such as a name-change certificate or marriage certificate.
Bring any instructions from the organization receiving the affidavit. This is especially helpful for documents being used outside Alberta, in the United States, or internationally. Requirements can vary by destination, and a document that is acceptable for one purpose may need a different form of authentication for another.
If you need a witness for another part of the document, do not assume the commissioner can act as that witness. Some documents have separate witness rules, and the witness may need to be independent or meet certain eligibility requirements. Clarify this before the appointment so you do not have to make a second trip.
How to commission an affidavit step by step
1. Meet with an authorized official
A commissioner for oaths or notary public will review the document enough to confirm what needs to be signed and witnessed. They will check your identification and may ask whether you understand the document and are signing voluntarily.
This is not legal advice. If you do not understand what a statement means, whether you should include it, or whether an affidavit is the right document, speak with a lawyer before you swear or affirm it. Once commissioned, an affidavit is a formal legal statement.
2. Swear an oath or make an affirmation
The commissioner will ask you to swear or affirm that the contents of the affidavit are true to the best of your knowledge and belief. Answer honestly. Making a false statement in an affidavit can have serious legal consequences, including potential perjury-related consequences depending on the circumstances.
You should never feel rushed into swearing to something you have not read or cannot verify. If part of the affidavit is based on information from someone else, make sure the document explains that where appropriate. A lawyer can advise on how this should be handled for a court matter.
3. Sign while the commissioner watches
After the oath or affirmation, sign the affidavit in the designated area. The commissioner will then sign, date, and complete their portion. Check the date, location, spelling of your name, and commissioner information before leaving.
A small error can matter. If the commissioner’s section is incomplete, the location is wrong, or a required exhibit is not marked, the receiving party may reject the affidavit. Taking one minute to review the finished document can save days of follow-up.
4. Keep the original safe
Many courts, legal offices, and agencies require the original commissioned affidavit. Make a clear copy or scan for your records, but protect the original from damage or loss. Do not alter it after it has been sworn or affirmed. If information needs to change, you may need to prepare and commission a new affidavit.
Commissioner for oaths vs. notary public
For many affidavits used in Alberta, a commissioner for oaths is sufficient. A notary public may be needed when the document is intended for use outside the province, outside Canada, or by an organization that specifically asks for notarization.
The distinction matters because a commissioner’s authority can be limited by jurisdiction and document type. A notary public may have broader recognition, but not every document needs that added step. The right choice depends on where the affidavit will be used and what the receiving organization requires.
For U.S. readers, terminology can be different. In many states, affidavits are notarized rather than commissioned, and state-specific rules apply. If your affidavit will be filed or used in the United States, confirm whether the recipient requires a U.S. notarial certificate, an apostille, a consular process, or another form of authentication. Do not assume an Alberta commission alone will meet an American agency’s requirements.
Common mistakes that delay affidavits
Most affidavit issues are avoidable. The most common problems include signing before the appointment, bringing expired or insufficient ID, omitting attachments, using the wrong form, and booking the wrong type of official for the document’s destination.
Another frequent mistake is treating an affidavit as a simple formality. You are making a sworn or affirmed statement, so the facts must be accurate. If the affidavit is for a legal dispute, estate administration, divorce, custody matter, or other high-stakes situation, legal advice before signing can be well worth the time.
Get the right help for an urgent affidavit
When an affidavit is due quickly, convenience should not come at the expense of proper execution. A mobile appointment can be practical if you are at home, at work, in a hospital, or managing a time-sensitive filing. The key is having the completed unsigned document, proper ID, and all exhibits ready when the commissioner arrives.
