Prob. Code, § 11466

The court may order property in the estate distributed to a person entitled to it under the final order for distribution, if the person gives a bond conditioned on payment by the person of the amount of a contingent or disputed debt that becomes absolute or established. The amount of the bond shall be determined by the court, not to exceed the fair market value on the date of distribution of the property received by the distributee, less the amount of liens and encumbrances. In the case of a disputed debt or in the case of a contingent debt where litigation is required to establish the contingency, the cost of the bond is recoverable from the unsuccessful party as a cost of litigation.
