Cal. Probate Code § 3923

(a) As used in this section, “California Uniform Gifts to Minors Act” means former Article 4 (commencing with Section 1154) of Chapter 3 of Title 4 of Part 4 of Division 2 of the Civil Code. (b) Any transfer of custodial property, as now defined in this part, made before January 1, 1985, is validated, notwithstanding that there was no specific authority in the California 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. (c) This part applies to all transfers made before January 1, 1985, in a manner and form prescribed in the California Uniform Gifts to Minors Act, except insofar as the application impairs constitutionally vested rights. (d) To the extent that this part, by virtue of subdivision (c), does not apply to transfers made in a manner prescribed in the California Uniform Gifts to Minors Act or to the powers, duties, and immunities conferred by transfers in that manner upon custodians and persons dealing with custodians, the repeal of the California Uniform Gifts to Minors Act does not affect those transfers or those powers, duties, and immunities.
