Every person of sane mind and eighteen (18) years or older in age, may devise, bequeath, or dispose of, by his or her will, executed in the manner required by this chapter, all real estate and all personal estate, which he or she shall be entitled to either at law or in equity at the time of his or her death and which, if not so devised, bequeathed or disposed of, would devolve upon the heir at law, or upon his or her executor or administrator, but not including an estate tail. The power hereby given shall extend to all real estate, including all estate per autre vie, and all estates, whether they shall be freehold or of any other tenure, and all estates, whether they shall be corporeal or incorporeal hereditaments, and also to all contingent, executor, or other future interests, in any real or personal estate, whether the testator may or may not be ascertained as the person or one of the persons in whom the estates respectively may become vested, and whether he or she may become entitled thereto under the instrument by which the estates respectively were created, or under any disposition thereof by deed or will, and also to all rights of entry for conditions broken and other rights of entry, and also to such of the same estates, interests and rights respectively, and other real and personal estate, as the testator may be entitled to at the time of his or her death, notwithstanding that he or she may become entitled to the same subsequently to the execution of his or her will.
