Summarize the following:
The forms filed with the clerk’s office need to be served on your spouse by a person that meets certain requirements. A server must be someone other than you who is over 18 years old, including:  a friend; a relative; the county sheriff’s office; or a person hired to serve legal papers called a process server. All the papers you filed with the clerk, along with a blank response form  must be served on the other spouse. Two methods of service are appropriate in an annulment in California:  personal service, which means in-person service; or service by mail, which requires the other party to agree to service in this manner and also a completed Notice of Acknowledgement and Receipt. You must file proof that service has been completed.  Fill out, copy, and file the proof of service along with the Notice of Acknowledgment and Receipt if service by mail was completed and file it with the same clerk's office that you filed the documentation that was used to begin the annulment proceeding. After the forms are served, the other party has 30 days to respond. Whether the other party files a response and whether you and the other party have come to an agreement regarding the annulment will dictate the next steps in the legal proceeding.   If the spouse did not file a response and you do not have an agreement, you can file a request for a default judgment in order to obtain the required outcome in the case.   If the spouse did not file a response but you do have an agreement, you can write up that agreement and file it with the court in order to obtain a default judgment with an agreement.   If the spouse did file a response and you have an agreement, this is called an uncontested proceeding and you can write up your agreement and file it with the court to obtain the desired result.   If the spouse did file a response and you do not have an agreement, this is a contested case and you will have to resolve the issues before a judge.
