Ind. Code § 29-1-3-8 – Afterborn or adopted children; omitted heirs

(a) When a testator fails to provide in his will for any of his children born or adopted after the making of his last will, such child, whether born before or after the testator's death, shall receive a share in the estate of the testator equal in value to that which he would have received if the testator had died intestate, unless it appears from the will that such omission was intentional, or unless when the will was executed the testator had one (1) or more children known to him to be living and devised substantially all his estate to the spouse who survives him.
(b) If, at the time of the making of his will, the testator believes any of his children to be dead, and fails to provide for such child in his will, the child shall receive a share in the estate of the testator equal in value to that which he would have received if the testator had died intestate, unless it appears from the will or from other evidence that the testator would not have devised anything to such child had he known that the child was alive.
