An acknowledgment of service is a signed confirmation that a person received specified family law documents on a particular date. It is used to create a documented record of service that can be filed with the court without requiring a process server's affidavit.

The acknowledgment must identify the documents received, the date received, and be signed by the receiving party. It is then filed with the court as proof of service. The response deadline runs from the date of the acknowledgment.

Acknowledgments of service are typically used in cooperative cases or when an attorney accepts service for a represented party. They should not be used in situations where the receiving party might later claim they did not actually receive the documents or did not understand what they were signing.
