Return of Service vs. Affidavit of Service
These two documents both prove service but are not identical. Here is how they differ and when each is used.
Return of service and affidavit of service are terms that are often used interchangeably, but they are not always the same thing. Both document that legal papers were delivered — the difference is mostly in form and formality.
What they have in common
Both are records prepared by the person who served the documents. Both describe who was served, what was served, and when, where, and how it happened. Both are filed with the court as proof that notice was given.
How they differ
- Return of service — a general term for the server's report of service. In some courts it is a standardized form provided by the court itself.
- Affidavit of service — a return of service that is sworn under oath, signed before a notary or other authorized official. The oath adds a layer of legal weight, because the server is formally attesting to the truth of the statements.
When each is used
Which document a court requires depends on the jurisdiction and the type of case. Some courts accept a signed return; others specifically require a notarized affidavit. Professional servers know which form each court expects and prepare the correct one.
Why the distinction matters
Using the wrong form, or an incomplete one, can slow a case down. Because an affidavit is sworn, errors in it carry more serious consequences. In every case, the goal is the same: a clear, truthful, and properly executed proof of service that the court will accept.
