(2) If the witness was competent at the time of attesting its execution and afterward became incompetent;
(3) If testimony of a witness cannot be obtained within a reasonable time.
(B) When offered for probate, a will shall be admitted to probate and allowed when there has been a prior judgment by a probate court declaring that the will is valid pursuant to section 2107.084 of the Revised Code, if the will has not been removed from the possession of the probate judge and has not been modified or revoked under division (C) or (D) of section 2107.084 of the Revised Code.
