Filing is the act of submitting a document to the Clerk of the Superior Court so it becomes part of the official court record. In Arizona family law, documents are filed with the Maricopa County Superior Court either in person, by mail, or electronically through the court’s e-filing system.

A document is not filed until the clerk accepts it and stamps it with the filing date. The filing date matters for deadlines, for calculating response periods, and for establishing the timeline of the case. A document submitted after a deadline is late regardless of when it was drafted.

Every filed document in a family law case should be served on the other party or their attorney. Proof of service must be filed with the court. Filing something without serving it does not give the other party notice and can create procedural problems that affect the case.

Read everything before you file it. This applies to cover sheets, proposed orders, stipulations, and every other document that goes out under your name or your client’s signature. A filing is a formal representation to the court. It should be accurate, complete, and carefully proofread.
