Cal. CCP § 1255.240

(a) If the court determines that an applicant is entitled to withdraw any portion of a deposit that another party claims or to which another person may be entitled, the court may require the applicant, before withdrawing such portion, to file an undertaking. The undertaking shall secure payment to such party or person of any amount withdrawn that exceeds the amount to which the applicant is entitled as finally determined in the proceeding, together with interest as provided in Section 1255.280. If withdrawal is permitted notwithstanding the lack of personal service of the application for withdrawal upon any party to the proceeding, the court may also require that the undertaking indemnify the plaintiff against any liability it may incur under Section 1255.230. The undertaking shall be in such amount as is fixed by the court, but if executed by an admitted surety insurer the amount shall not exceed the portion claimed by the adverse claimant or appearing to belong to another person. If executed by two or more sufficient sureties, the amount shall not exceed double such portion.

(b) If the undertaking is required primarily because of an issue as to title between the applicant and another party or person, the applicant filing the undertaking is not entitled to recover the premium reasonably paid for the undertaking as a part of the recoverable costs in the eminent domain proceeding.
