Such designation, in the form, if any, required by the terms of the instrument governing such trust, shall be effective to give to such designated beneficiary the benefits provided under the terms of the instrument governing such trust, notwithstanding any law which would otherwise make ineffective such designation, including, but without limitation to, any rule against perpetuities or law respecting testamentary dispositions; provided, that any such designation must be in writing.

(d) Any trustee or other person, including any person, corporation or national banking association, may make payment to any person, or his or her legal representative, designated as provided in subsection (c), and no trustee or other person shall be liable in any way to any person for making payment to a person, or his or her legal representative, so designated.
