Posthumous children are those who, at the death of their father, are en ventre sa mere, that is, those who are conceived but not born. By the early common law such children could not inherit,585 but the disability does not exist in the United States,586 though in some states it has been removed only as to children of the intestate, and does not apply to collateral heirs.587 In a number of states it is provided by statute that the child must be born within ten months after the death of the intestate in order to inherit.588 A disposition of the property before such a child is born will be binding on the child, and the title will not be avoided as to a purchaser, though the child can claim its share in the proceeds of the sale, as against the other heirs.589
