Affidavit of Service in Alberta: Who Swears It and How to Get It Commissioned
An affidavit of service is a sworn written statement that proves court documents were delivered to someone. The person who actually served the documents is the one who swears it. In other words, if your friend, process server, or adult family member handed over the papers, that person must sign the affidavit of service in front of a commissioner for oaths or notary.
That’s the short answer. The tricky part is making sure the affidavit says enough, uses the right form, and gets commissioned properly before it’s filed with the court.
This post is general information, not legal advice. Service rules can be strict, and the right method can change depending on the court, document, and type of case.
What an affidavit of service is
An affidavit of service is the court’s proof that a person received legal documents, or that the documents were sent or delivered in a way the rules allow.
Courts don’t usually just take someone’s word for it. If a filing deadline, hearing date, divorce step, landlord application, or civil claim depends on service, the court needs a sworn record.
That sworn record is the affidavit.
A typical affidavit of service tells the court:
What documents were served
Who served them
Who received them
When service happened
Where service happened
How service happened
How the person served was identified
What supporting documents are attached as exhibits, if any
For example, if a claim was personally handed to a defendant, the affidavit may say the server attended at a specific address on a specific date and time, handed the documents to the defendant, and knew it was the defendant because the person confirmed their name.
That affidavit then becomes proof of service Alberta court staff, clerks, judges, or decision-makers can review.
The key point is simple: the affidavit of service is not the service itself. It is the sworn evidence that service happened.
Who swears it
The person who served the documents swears the affidavit.
That sounds obvious, but it’s one of the most common points of confusion. If someone else served the documents for you, you usually can’t swear the affidavit for them. You weren’t the person who handed over, mailed, emailed, posted, couriered, or otherwise delivered the documents.
So, who can swear affidavit of service documents?
Usually, it will be one of these people:
A process server
A friend or relative who is allowed to serve
Another adult who delivered the documents
A party to the matter, if the rules allow that party to serve
Someone who sent the documents by an approved method, such as mail or email, where permitted
If a process server personally served someone, the process server swears the affidavit. If your adult sibling served the documents, your sibling swears it. If you served the documents yourself and the rules allow you to do that, then you swear it.
The affidavit must be signed in person before someone authorized to commission it, unless the commissioner is using a legally accepted remote commissioning process. Don’t sign it at home first. The commissioner needs to witness the signature and administer the oath, affirmation, or solemn declaration.
For an affidavit of service Alberta courts can accept, the signer should bring proper identification and be ready to confirm that the contents are true.
What it must state
An affidavit of service needs enough detail for the court to understand exactly what happened. Vague wording can cause trouble, especially if the other side says they were not served.
A strong affidavit usually answers these questions.
What was served
List each document clearly. For example:
Statement of Claim
Application
Affidavit
Notice to Attend
Divorce documents
Residential Tenancy Dispute Resolution Service application
If there were several documents in one package, list them all. Don’t write “court papers” if the form asks for the names of the documents.
For an affidavit of service divorce Alberta filing, the court may expect the divorce documents to be named clearly, because different divorce forms may have different service requirements.
Who was served
Use the person’s full name if known. If the document was served on a corporation, landlord, tenant, lawyer, agent, or other representative, describe who received it and why that person was the correct recipient.
For personal service, the affidavit should explain how the server knew the person was the right person. That could be because:
The person confirmed their name
The server personally knew them
The person matched a photograph
Someone at the residence identified them
For a personal service affidavit Alberta matter, this identification detail can matter a lot.
When and where service happened
Use the full date, time, and location.
A weak version says, “I served them last week.”
A stronger version says, “I served John Smith on January 12, 2026, at 7:15 p.m. at 123 Example Street NW, Edmonton, Alberta.”
Courts need specifics. If the date of service affects a response deadline, one wrong date can create a bigger problem.
How service happened
The affidavit should say how the documents were served. Common examples include:
Personally handing the documents to the person
Sending documents by registered mail, where allowed
Emailing documents, where allowed
Leaving documents with an adult at a permitted address, where allowed
Serving a lawyer or authorized representative, where allowed
Don’t assume every method works for every case. Service rules vary across the Court of King’s Bench, Alberta Court of Justice, family matters, civil matters, and the RTDRS. An RTDRS affidavit of service may have different service instructions than a King’s Bench family filing.
What exhibits are attached
Some affidavits include exhibits. These are supporting documents attached to the affidavit.
Common affidavit of service exhibits include:
A copy of an email sent
A delivery confirmation
A registered mail receipt
A tracking page
A photograph of the package or posted document
A copy of the documents served, if required
The commissioner may need to mark the exhibit properly. This usually means adding exhibit wording, signing or stamping it, and connecting it clearly to the affidavit.
Forms
There isn’t only one affidavit of service form for every situation in Alberta. The correct form depends on the court or tribunal and the type of matter.
You may see forms for:
Court of King’s Bench civil matters
Court of King’s Bench family or divorce matters
Alberta Court of Justice matters
Residential Tenancy Dispute Resolution Service matters
Small claims or civil claims
Estate, guardianship, or other court applications
If you’re filing in the Court of King’s Bench, make sure you’re using the correct affidavit of service form Court of King's Bench for your matter. A divorce file, civil action, application, or family matter may not use the exact same wording.
Forms often include blanks for:
Court file number
Judicial centre
Names of the parties
Name of the person who served the documents
Documents served
Date, time, and place of service
Method of service
Signature of the person swearing
Commissioner’s signature and stamp
Read the form before going to a commissioner. If the form has blank sections that should be completed before commissioning, fill them in first. A commissioner can witness your signature and administer the oath, but they generally won’t choose the legal form for you or tell you which service rule applies.
If you’re not sure which form applies, check the court’s website, the instructions you received from the court or tribunal, or speak with a lawyer.
Commissioner for Alberta courts
For Alberta court documents, an affidavit is usually sworn or affirmed before a commissioner for oaths in and for Alberta. A commissioner for oaths can witness the signature and complete the jurat, which is the section at the end showing when, where, and before whom the affidavit was sworn.
If you need an affidavit of service commissioner Edmonton, look for someone who regularly commissions Alberta court affidavits. Experience helps because affidavits often include exhibits, court captions, file numbers, and details that need to be handled carefully.
Document Genie provides commissioner for oaths services for Alberta court affidavits, including affidavits of service.
Commissioner or notary
For most Alberta court affidavits, a commissioner for oaths is enough. A notary public can also commission many documents, but not every affidavit needs notarization.
A notary may be needed when the document is going outside Alberta, outside Canada, or to a court or organization that specifically asks for notarization.
Document Genie also provides notary public services when notarization is needed, including for courts outside Alberta.
The safest approach is to check what the receiving court, tribunal, or organization requires. If it says “commissioner for oaths,” a commissioner may be fine. If it says “notary public,” use a notary.
What to bring
Bring the full package, not just the signature page. The commissioner needs to see what you’re swearing or affirming.
Bring:
The completed affidavit of service, unsigned
Government-issued photo ID
Any exhibits that must be attached
Receipts, tracking pages, emails, screenshots, or delivery confirmations
The court file number, if available
Instructions from the court or tribunal, if you have them
The documents that were served, if the affidavit refers to them
Make sure the affidavit is complete before you arrive. Names, dates, addresses, times, and document titles should be filled in. If an exhibit is mentioned as “Exhibit A,” bring that exhibit with you.
Do not sign the affidavit before meeting the commissioner. The commissioner must witness the signature. If you already signed it, you may need to print a fresh copy and sign again.
If more than one person served documents, each person may need their own affidavit for what they personally did. One person should not swear to facts they don’t know.
Common mistakes
Small errors can slow down a filing or cause the court to question service. Watch for these common issues:
Signing before seeing the commissioner The affidavit must be signed in front of the commissioner or notary.
Using vague document names Write the actual document titles instead of “papers” or “forms.”
Missing the date, time, or location Service details need to be specific, especially when deadlines depend on them.
Attaching exhibits without proper marking Exhibits should be clearly identified and connected to the affidavit.
Swearing an affidavit for someone else’s service The person who served the documents should swear to the service they performed.
FAQ
Can I serve and swear it myself?
Sometimes, yes. If the rules for your type of case allow you to serve the documents yourself, then you can swear the affidavit about what you did.
That said, some matters require service by someone else, or have special rules about who may serve. Divorce, family, civil, landlord and tenant, and other matters may differ. Check the rules for your court or tribunal before serving.
Notary or commissioner?
For Alberta court affidavits, a commissioner for oaths is usually enough. A notary public is often used when the document must be notarized, will be used outside Alberta, or the receiving organization asks for a notary.
If the document is staying in Alberta court and says it can be sworn before a commissioner, a commissioner is usually the right choice. If it’s going to another province, another country, or a non-Alberta court, ask whether notarization is required.
Service by email or mail?
Email or mail may be allowed in some matters, but not all. It depends on the court, the document, the rules, and sometimes whether the other person agreed to accept service that way.
If you served by email, bring proof such as the sent email, delivery information, attachments, and any confirmation. If you served by mail, bring receipts, tracking, or delivery confirmation.
Don’t guess on service rules. If you’re unsure whether email or mail is valid for your matter, check the court instructions or get legal advice.
Can exhibits be photocopies?
Often, yes. Many affidavit exhibits are copies, such as printed emails, tracking pages, receipts, or copies of served documents.
The bigger issue is whether the exhibit is clear, complete, and properly marked. If the court needs an original for a specific reason, a photocopy may not be enough. Bring the best copy you have, and bring the original too if you have it.
