Okla. Stat. tit. 84, § 84-106: Revocation of subsequent will

If, after making a will, the testator duly makes and executes a

subsequent will, the destruction, canceling or revocation of the

latter does not revive the former, unless it appears by the terms of

such revocation that it was his intention to renew the former will,

or unless after such destruction, canceling or revocation, he

republishes the prior will. R.L. 1910, Sec. 8363.
