Cal. R. 3.1202
An ex parte application must state the name, address, and telephone number of any attorney known to the applicant to be an attorney for any party or, if no such attorney is known, the name, address, e-mail address, and telephone number of the party if known to the applicant.
(Subd (a) amended effective January 1, 2016.)
If an ex parte application has been refused in whole or in part, any subsequent application of the same character or for the same relief, although made upon an alleged different state of facts, must include a full disclosure of all previous applications and of the court's actions.
An applicant must make an affirmative factual showing in a declaration containing competent testimony based on personal knowledge of irreparable harm, immediate danger, or any other statutory basis for granting relief ex parte.
