DISPOSITION OF INTEREST PASSING BECAUSE OF EVENT OTHER THAN DECEDENT'S DEATH AND DISCLAIMED BY INDIVIDUAL.

(a) Subject to Subsection (b):

(1) if by law or under the instrument creating the disclaimed interest the descendants of a disclaimant of an interest passing because of an event not related to the death of a decedent would share in the disclaimed interest by any method of representation under Section 240.051(e)(2)(B), the disclaimed interest passes only to the descendants of the disclaimant living at the time of the event that causes the interest to pass; or

(2) if the disclaimed interest would have passed to the disclaimant's estate under Section 240.051(e)(2)(B), the disclaimed interest instead passes by representation to the descendants of the disclaimant living at the time of the event that causes the interest to pass.

(b) If no descendant of the disclaimant is living at the time of the event described by Subsection (a)(1), the disclaimed interest passes to those persons, including the state but excluding the disclaimant, and in such shares as would succeed to the transferor's intestate estate under the intestate succession law of the transferor's domicile had the transferor died immediately before the event described by Subsection (a)(1), except that if the transferor's surviving spouse is living but remarried before the event, the transferor is considered to have died unmarried immediately before the event.

(c) On the disclaimer of a preceding interest, a future interest held by a person other than the disclaimant takes effect as if the disclaimant had died immediately before the time the disclaimer takes effect under Section 240.051(c)(1)(A), but a future interest held by the disclaimant is not accelerated in possession or enjoyment.
