Official Ontario family court form guide
Form 6B: Affidavit of Service
Ontario family court Form 6B is completed by the person who served court documents. The server swears or affirms how, when, where and on whom service was carried out. Download the current form from Ontario Court Services and check the Family Law Rules for the documents and service method involved.
Use the current PDF or Word file from Ontario Court Services. Saved copies can become outdated when court forms or rules change.
What the affidavit proves
Form 6B gives the court the server’s sworn evidence about delivery of identified documents. It is completed after service, not used to perform service. The server must be able to describe the method and details from personal knowledge and identify every document served.
Rules about who may serve, when special service is required, acceptable alternatives and deadlines depend on the document and proceeding. Commissioning cannot correct an unauthorized service method. If you are unsure, review the Family Law Rules, court guidance or advice from a licensed Ontario lawyer or paralegal before taking further steps.
Record details immediately after service
- Court name, municipality, file number and the parties’ names as shown on the case documents.
- Exact title of every document served, including the issue or signature date where needed.
- Date, time, address and method of service.
- Full name of the person served and how the server identified that person.
- Details required by the form for service on a lawyer, agency, corporation or another person.
- Any exhibit or attachment the official form requires to support the described method.
Write notes while events are fresh. Do not estimate a time, invent identification details or copy another person’s account. If more than one person served documents or different methods were used, ask whether separate affidavits are required.
Prepare for commissioning
- Download the official form: choose the current English or French version from Ontario Court Services.
- Complete the case heading: copy it exactly from the filed court documents.
- Describe the service: list the documents and answer only the section matching what occurred.
- Bring records: take service notes, relevant copies or requested exhibits, and valid government-issued photo identification.
- Do not sign yet: the server swears or affirms the affidavit and signs in the commissioner’s presence.
- Review before filing: check the jurat, dates, document list and any exhibit marking, then follow the court’s current filing directions.
The server must attend
The person with direct knowledge of service is the person who swears or affirms Form 6B. A party cannot bring in the server’s unsigned form and swear it for them.
Common questions
Can a party to the case serve the documents?
The answer depends on the document, method and applicable rules. Check before service. A commissioner can witness the affidavit but cannot decide whether the service complied with the Family Law Rules.
What if I made a mistake in the document list?
Correct the form before swearing it. If it has already been commissioned or filed, do not alter it silently; ask the court office or a legal professional how to provide accurate evidence.
Does commissioning mean the court accepts service?
No. Commissioning confirms the oath or affirmation and signature process. The court decides whether the evidence and service comply with the rules.
Need a commissioner or notary?
Bring the unsigned document, valid identification and the receiving organization’s instructions. Eligibility for online commissioning depends on the document and recipient.
