Quick answer

Form MC-031 is the Attached Declaration approved for optional use by the Judicial Council of California. It gives you space for a statement signed under penalty of perjury and must be attached to another form or court paper before filing. MC-025 is a general attachment; MC-031 is specifically a sworn declaration. JustFill prepares the PDF and includes the first clean completed download, but does not file it or provide legal advice.

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.

Field-by-field breakdown

What each section of MC-031 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.

Header

Plaintiff or petitioner, defendant or respondent, and the case number, so the attachment can be matched to its file.

Declaration

The sworn text itself. Everything written here is under penalty of perjury.

Role

Whether you sign as plaintiff, defendant, petitioner, respondent, attorney for a named party, or another capacity you specify.

Signature block

The penalty-of-perjury statement under the laws of the State of California, the date, your typed or printed name and your signature.

Common mistakes to avoid

  • 1Filing MC-031 on its own. The form states it must be attached to another form or court paper before it can be filed.
  • 2Using MC-025 when the content is a sworn declaration. MC-031 is the declaration version.
  • 3Leaving the role checkbox blank.
  • 4Forgetting that everything on the sheet is sworn, including anything added as background.

MC-031 example — what a filled-out form looks like

A fictional petitioner needs one extra page for a short first-person statement supporting another court paper. The facts and case details below are deliberately invented.

Plaintiff/Petitioner

ALEX EXAMPLE

Defendant/Respondent

CASEY SAMPLE

Case number

SAMPLE-CASE-NO.

Copy the exact case number from the court paper this sheet supports.

Declaration

I am the petitioner in this matter. On August 1, 2026, I placed the blue sample folder in the locked cabinet. On August 3, 2026, I returned and found the cabinet still locked.

This illustrates a chronological first-person statement of invented facts, not language to copy into a real case.

Role

Petitioner

Date / printed name / signature

Date actually signed — ALEX EXAMPLE — signature

The person making the declaration signs under penalty of perjury.

These values are made up. They are here to show what belongs on each line, not to be copied — every name, number, and address on your own MC-031 has to be your own. Use only facts you can truthfully declare from personal knowledge, follow the rules and instructions for the court paper this sheet supports, and obtain legal advice when needed.
