This part applies to a creditor's or assignee's claims and ability to reach mandatory, support and discretionary interests regardless of whether such interests are subject to a spendthrift provision. To the extent not otherwise prohibited by this part, the court may authorize a creditor or assignee of the beneficiary to reach the beneficiary's distribution interest by attachment of present or future distributions to or for the benefit of the beneficiary or other means. The court may limit the award to such relief as is appropriate under the circumstances.
