California Probate Code
(a) Except as provided in subdivision (b), the share in a decedent's estate of a beneficiary who survives the decedent but who dies before distribution shall be distributed under this chapter with the same effect as though the distribution were made to the beneficiary while living.
(b) Subject to Section 21525, distribution may not be made under this chapter if the decedent's will provides that the beneficiary is entitled to take under the will only if the beneficiary survives the date of distribution or other period stated in the will and the beneficiary fails to survive the date of distribution or other period.
If a beneficiary satisfies the requirement of Section 11801, the beneficiary's share in the decedent's estate shall be distributed as follows:
(a) Except as otherwise provided in this section, distribution shall be made to the personal representative of the estate of the beneficiary for the purpose of administration in the estate of the beneficiary.
(b) If the beneficiary was issue of the decedent and died intestate while under the age of majority and not having been emancipated, distribution shall be made directly to the heirs of the beneficiary without administration in the estate of the beneficiary.
(c) If a person entitled to the beneficiary's share proceeds under Division 8 (commencing with Section 13000) (disposition of estate without administration), distribution shall be made under Division 8.
