Quick answer

Form MC-031 is the Attached Declaration approved for optional use by the Judicial Council of California. It gives you more space to write a declaration that you must sign under penalty of perjury, and it is always attached to another form or court paper before it is filed. Where MC-025 continues any item on any form, MC-031 is specifically the declaration version — the text you write is sworn.

What is MC-031?

MC-031 is the continuation sheet for sworn statements in California courts, and JustFill lets you type it in your browser rather than squeezing it into a printed box. The header carries the plaintiff or petitioner, the defendant or respondent and the case number. The body is the declaration. Below it a checkbox row records whether you sign as plaintiff, defendant, petitioner, respondent, attorney for a named party or another capacity, followed by the penalty-of-perjury statement, the date, your printed name and your signature.

Who fills out MC-031?

  • Anyone whose declaration does not fit on the form it supports
  • Parties adding sworn facts to a motion, response or application
  • Self-represented litigants continuing a declaration from another Judicial Council form
