Create a free accountWhat it is
APP-151 is only for a writ in a misdemeanor, infraction or limited civil case, or a writ challenging a postjudgment enforcement order in a small claims case. The form says not to use it for other writs or for appeals. Other small claims writs use SC-300. It cites California Rules of Court, rules 8.930–8.936.
When it is used
Unless a special statute sets an earlier deadline, the form says to file no later than 30 days after the trial court’s action or ruling, and that a late petition may be denied. Copies are served on the respondent court and each real party in interest, with proof such as APP-109 or APP-109E.
Section by section
Use the current official form and its instructions. The descriptions below identify the questions without choosing answers for your situation.
Petitioner, respondent court, real party in interest, and whether a stay is requested.
Contact details, the trial court case, the action or ruling challenged, its date, and any extraordinary reasons for filing after 30 days.
Whether the petitioner was a party, the other parties, and any appeal or earlier writ petition.
What the court failed to do, did that it must not do, or did without legal power, with the law and where the record shows it.
Why no other adequate remedy exists, the irreparable harm, and the orders or stay requested.
A transcript or official recording, or a declaration that it was ordered or why it is unavailable.
The ruling, the documents for and against the petitioner, and other necessary documents, or why they are not attached.
