SDCL § 55-1-38.1: Classification of interest as support interest.

If a trust instrument containing the distribution language specifically provides that the trustee exercise discretion in a reasonable manner with regard to a discretionary interest, then notwithstanding any other provision of §§ 55-1-38 to 55-1-43, inclusive, the distribution interest shall be classified as a support interest. A beneficiary's right to a distribution as well as a creditor's right regarding a beneficiary's support interest is governed by § 55-1-42.
