A. Any transfer of custodial property as now defined in the Uniform Transfers to Minors Act made before the effective date of that act is validated notwithstanding that there was no specific authority in the Uniform Gifts to Minors Act for the coverage of custodial property of that kind or for a transfer from that source at the time the transfer was made.
B. The Uniform Transfers to Minors Act applies to all transfers made before the effective date of that act in a manner and form prescribed in the Uniform Gifts to Minors Act, except insofar as the application impairs constitutionally vested rights or extends the duration of custodianships in existence on the effective date of that act.
C. Sections 2 and 21 [ 46-7-12, 46-7-31 NMSA 1978] of the Uniform Transfers to Minors Act with respect to the age of a minor for whom custodial property is held under that act do not apply to custodial property held in a custodianship that terminated because of the minor's attainment of the age of eighteen after June 17, 1973 and before the effective date of this section.
