Who may execute; signature; attestation
Every person eighteen (18) years of age or older, being of sound and disposing mind, shall have power, by last will and testament, or codicil in writing, to devise all the estate, right, title and interest in possession, reversion, or remainder, which he or she hath, or at the time of his or her death shall have, of, in, or to lands, tenements, hereditaments, or annuities, or rents charged upon or issuing out of them, or goods and chattels, and personal estate of any description whatever, provided such last will and testament, or codicil, be signed by the testator or testatrix, or by some other person in his or her presence and by his or her express direction. Moreover, if not wholly written and subscribed by himself or herself, it shall be attested by two (2) or more credible witnesses in the presence of the testator or testatrix.
Devise to witness void
If any person be a subscribing witness to a will wherein any devise or bequest is made to him and the will cannot otherwise be proven, such devise or bequest shall be void, and the witness shall be competent as to the residue of the will as if a devise or bequest had not been made to him, and he may be compelled to testify. If such witness would have been entitled to any share of the testator's estate in case the will were not established, then so much of such share shall be saved to the witness as shall not exceed the value of the devise or bequest made to him in the will.
Creditor competent witness to will
Any creditor shall be a competent subscribing witness to a last will and testament; but any special provision in favor of such creditor in the will, either by admitting the debt or by providing for its payment or by giving it a preference, shall be void, and such claim shall stand as though the provision had not been made.
