Ohio Rev. Code § 2107.38: Destruction of a subsequent will.

If a testator executes a second will, the destruction, cancellation, or revocation of the second will shall not revive the first will unless the terms of the revocation show that it was the testator's intention to revive and give effect to the testator's first will or unless, after the destruction, cancellation, or revocation of the second will, the testator republishes the testator's first will.
