An affidavit of service is a sworn written statement by the person who served the documents. It is the main way you prove to a court that someone was properly served.
What it should contain
- Who the deponent (the person serving) is
- The date, time and place of service
- Which documents were served, usually attached as exhibits
- Who was served and how they were identified
- How the documents were handed over
A simple example
Queensland’s court-approved sample is short and factual. The process server states the date they served the defendant with a claim and statement of claim, how the person was identified (for example, by asking them to confirm their name), and attaches a copy of the documents served. The affidavit is then sworn or affirmed before a person authorised to witness it.
Why details matter
A vague or incomplete affidavit can lead to questions, delay or a refusal to accept that service took place. Good records made at the time are the foundation of a good affidavit.
When service was not achieved
Where documents could not be served, an affidavit setting out the attempts can support an application for substituted service. See our guide to substituted service.
Divorce applications
In divorce proceedings, the Federal Circuit and Family Court uses specific forms, including an Affidavit of Service by Hand (Divorce) and an Affidavit of Service by Post (Divorce), depending on the method of service used.
