(a) If the decedent has left a surviving child or children or issue of children among the persons who are by law entitled to succeed to his estate, and any of them, before the close of administration, has died before reaching the age of eighteen (18) and not having married, no administration of such deceased issue’s estate is necessary, but all the estate which such deceased issue is entitled to receive by inheritance must, without administration, be distributed to the heirs at law of the deceased issue.
(b) If any other heir, legatee, or devisee shall die after the decedent’s death and before distribution, property to which he might be entitled shall be distributed to the representative of his estate or directly to his heirs, legatees or devisees or the persons entitled thereto.
