Requisites of will.
Section 618
SEC. 618. Requisites of will. — No will, except as provided in the preceding section, shall be valid to pass any estate, real or personal, nor charge or affect the same, unless it be in writing and signed by the testator, or by the testator's name written by some other person in his presence, and by his express direction, and attested and subscribed by three or more credible witnesses in the presence of the testator and of each other. The attestation shall state the fact that the testator signed the will, or caused it to be signed by some other person, at his express direction, in the presence of three witnesses, and that they attested and subscribed it in his presence and in the presence of each other. But the absence of such form of attestation shall not render the will invalid if it is proven that the will was in fact signed and attested as in this section provided.
