California Code, Probate Code - PROB § 15307

Notwithstanding a restraint on transfer of a beneficiary's interest in the trust under Section 15300 or 15301, any amount to which the beneficiary is entitled under the trust instrument or that the trustee, in the exercise of the trustee's discretion, has determined to pay to the beneficiary in excess of the amount that is or will be necessary for the education and support of the beneficiary may be applied to the satisfaction of a money judgment against the beneficiary. Upon the judgment creditor's petition under Section 709.010 of the Code of Civil Procedure, the court may make an order directing the trustee to satisfy all or part of the judgment out of the beneficiary's interest in the trust.
