Okla. Stat. tit. 84, § 84-132: Provision for children unintentionally omitted

When any testator omits to provide in his will for any of his

children, or for the issue of any deceased child unless it appears

that such omission was intentional, such child, or the issue of such

child, must have the same share in the estate of the testator, as if

he had died intestate, and succeeds thereto as provided in the

preceding section. R.L. 1910, Sec. 8372.
