California Code, Family Code - FAM § 20032

(a) Each and every hearing in a proceeding described in Section 20031 in which child or spousal support is at issue, including related contempt matters, shall be set by the clerk of the court for hearing within 30 days of filing.

(b) At any hearing in which child or spousal support is at issue, each party, both moving and responding, shall bring to the hearing, copies of the last two federal and state income tax returns filed by the party and pay stubs from the last four full months immediately preceding the hearing received by the party, and shall serve those documents on the opposing party at least five days in advance of the hearing date.  Willful failure to comply with these requirements or any of the requirements of this pilot project may result in a citation for contempt under Title 5 (commencing with Section 1209) of Part 3 of the Code of Civil Procedure, or in the court's discretion, the court may refuse to grant relief requested or may impose evidentiary sanctions on a party who fails to submit these documents.  The clerk shall cause to be placed on the face sheet of any moving papers for child or spousal support at the time of filing, a notice informing the parties of the requirements of this section.  The notice shall also inform the parties that prior to the hearing, they must meet with the Attorney-Mediator pursuant to Section 20034.  That meeting may occur in advance of the hearing dates by agreement of the parties, or on the day of the hearing.

(c) No continuance of any hearing involving child or spousal support shall be granted by a court without an order setting an interim support level unless the parties stipulate otherwise or the court finds good cause therefor.
