Section 623
SEC. 623. Will, how revoked. — No will shall be revoked, except by implication of law, otherwise than by some will, codicil, or other writing executed as provided in case of wills; or by burning, tearing, canceling, or obliterating the same with the intention of revoking it, by the testator himself, or by some other person in his presence, and by his express direction. If burned, torn, canceled, or obliterated by some other person, without the express direction of the testator, the will may still be established by the court, and the estate distributed in accordance therewith, if its contents and due execution, and the fact of its unauthorized destruction, cancellation, or obliteration is established by full evidence to the satisfaction of the court.
