Serving documents in a family law case might seem simple, but it plays a significant role in keeping your case moving. The court needs proof that you delivered (served) the right documents to the intended recipient. That’s exactly what the Affidavit of Service (Form 6B) is for. This form is a required document that confirms when, how, and to whom your documents were served.
If this is your first time handling legal paperwork, it’s normal to feel unsure about what’s expected. But once you understand the process, completing and filing Form 6B becomes much more straightforward.
This guide explains who can serve documents and how to complete and file Form 6B, so you can move forward with confidence.

What Is an Affidavit of Service (Form 6B)?
An Affidavit of Service (Form 6B) is a legal document used in family court proceedings. It provides sworn proof that legal documents have been properly delivered (served) to the appropriate party.
This party can be an ex-spouse, ex-partner, or another individual. For instance, the plaintiff must provide (serve) a copy of the Plaintiff’s Claim Form to the defendant in a case.
An Affidavit of Service ensures that all parties are informed about the court proceedings and the correct documents, upholding fairness and transparency. This sworn legal document outlines the following:
- Who was served (provided with) documents;
- Who did the serving (who delivered them);
- When they were served; and
- How they were served.
What Is the Purpose of an Affidavit of Service (Form 6B)?
Serving documents is a critical part of the family court process. Each party must “serve” the other with documents during every step in a family court case. By serving documents, you’re being transparent about the steps you’re taking and the information you plan to present to the court. Accordingly, you’re giving them a fair opportunity to respond.
This Affidavit can:
- Prevent the other party from claiming they didn’t receive copies of documents, which can cause issues.
- Encourage your case to move forward, as it may be stalled if the other party claims you didn’t serve them with documents.
Also, an Affidavit of Service upholds fairness, allowing the other party to:
- Know about a case that’s been started against them
- Respond to the claims made against them
- Make claims of their own
All Affidavits must be sworn or affirmed before an individual authorized to administer oaths and affirmations by law. Knowingly making false or inaccurate statements in an Affidavit is considered perjury, which is a criminal offence. Therefore, being truthful is critical.
Who Can Complete and Swear an Affidavit of Service (Form 6B)?
Only the person who served the documents can complete and swear Form 6B. This person is called the server.
In family law matters, you cannot serve the documents yourself. You must ask someone else who is at least 18 years old to serve the documents on your behalf. This could be a friend, family member, or a professional process server.
The server must swear or affirm the Affidavit in front of a notary public or a qualified Commissioner of Oaths.
Who Cannot Complete an Affidavit of Service (Form 6B)?
The person who received the documents cannot fill out or swear the Affidavit of Service. That includes the opposing party or anyone on their behalf.
If your case involves special services, such as documents that could result in jail time, then you cannot serve the documents yourself. You must ask another adult or hire a professional server to do it.

Arranging for the Service of Documents
Whoever is serving documents should take notes that include the name of the person served, date, time, and manner of service. Doing so will give them the information they need to complete an Affidavit of Service.
Certain documents must be served in specific ways. For instance, a Plaintiff’s Claim cannot be served on an individual by regular letter mail or fax. Typically, a document can be served on any day of the week.
Documents can generally be served using the following methods:
- Have a friend or co-worker serve the documents
- Hire a private process server or business associate to serve the documents
- Get your legal representative to arrange for the service of the documents.
