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.

justfill.app/f/...) & Multi-Page B2B PacketsTwo ways teams automate MC-031 across clients, contractors, and new hires:
1. Public Mobile Fill & E-Sign Link (justfill.app/f/…)
Upload once, get a shareable link you can text or email to 1–500 clients, contractors, or new hires. They fill it step-by-step on their phone and sign electronically with a SHA-256 audit seal.
2. Multi-Page Onboarding / Tax Packet Automation
Combine MC-031 with companion documents (e.g. W-9 + Direct Deposit Authorization + NDA, or I-9 + W-4 + State Withholding, or 2848 + 8821 + Tax Organizer) or batch-generate hundreds of copies from Excel/CSV.
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.
California Courts lists MC-031 as effective July 1, 2005 and provides the official blank from its current form-information page. Download that PDF, upload it to JustFill, and attach the completed declaration to the form or court paper it supports. Do not file MC-031 by itself.
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.
Plaintiff or petitioner, defendant or respondent, and the case number, so the attachment can be matched to its file.
The sworn text itself. Everything written here is under penalty of perjury.
Whether you sign as plaintiff, defendant, petitioner, respondent, attorney for a named party, or another capacity you specify.
The penalty-of-perjury statement under the laws of the State of California, the date, your typed or printed name and your signature.
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.
ALEX EXAMPLE
CASEY SAMPLE
SAMPLE-CASE-NO.
Copy the exact case number from the court paper this sheet supports.
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.
Petitioner
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.
