California Code, Code of Civil Procedure - CCP § 1281.8

(a) As used in this section, “provisional remedy” includes the following:

(b) A party to an arbitration agreement may file in the court in the county in which an arbitration proceeding is pending, or if an arbitration proceeding has not commenced, in any proper court, an application for a provisional remedy in connection with an arbitrable controversy, but only upon the ground that the award to which the applicant may be entitled may be rendered ineffectual without provisional relief. The application shall be accompanied by a complaint or by copies of the demand for arbitration and any response thereto. If accompanied by a complaint, the application shall also be accompanied by a statement stating whether the party is or is not reserving the party's right to arbitration.

(c) A claim by the party opposing issuance of a provisional remedy, that the controversy is not subject to arbitration, shall not be grounds for denial of any provisional remedy.

(d) An application for a provisional remedy under subdivision (b) shall not operate to waive any right of arbitration which the applicant may have pursuant to a written agreement to arbitrate, if, at the same time as the application for a provisional remedy is presented, the applicant also presents to the court an application that all other proceedings in the action be stayed pending the arbitration of any issue, question, or dispute which is claimed to be arbitrable under the agreement and which is relevant to the action pursuant to which the provisional remedy is sought.
