2.A term of a trust providing that the interest of a beneficiary is held subject to a spendthrift trust, or words of similar import, is sufficient to restrain both voluntary and involuntary transfer of the beneficiary's interest.

3.A beneficiary may not transfer an interest in a trust in violation of a valid spendthrift provision and, except as otherwise provided in this chapter, a creditor or assignee of the beneficiary may not reach the interest or a distribution by the trustee before its receipt by the beneficiary.
