(a) Where discretion is conferred upon the fiduciary with respect to the exercise of a power, its exercise by the fiduciary shall be considered to be proper unless the court determines that the discretion has been abused within the meaning of § 187 of the Restatement (Second) of Trusts, not §§ 50 and 60 of the Restatement (Third) of Trusts.
(b) A beneficiary eligible to receive distributions from a trust in the discretion of a trustee or other fiduciary has a discretionary interest in the trust. Discretionary interest in a trust is a mere expectancy, not a property right. A beneficiary eligible to receive distributions from a trust in the discretion of a trustee or other fiduciary, even if subject to an ascertainable standard (as defined in Treas. Reg. § 20.2041-1(c)(2) (26 CFR § 20.2041-1(c)(2)) or any successor provision thereto), has a discretionary interest in the trust. An interest that includes mandatory distribution language such as “shall” but is qualified by discretionary distribution language is a discretionary interest. A creditor may not directly or indirectly compel the distribution of a discretionary interest except to the extent expressly granted by the terms of a governing instrument in accordance with § 3536(a) of this title. Nothing within this subsection shall be deemed to alter the standard of review of the discretion of the trustee or other fiduciary under subsection (a) of this section.
