Okla. Stat. tit. 84, § 84-131: After-born children not provided for in will

Whenever a testator has a child born after the making of his

will, either in his lifetime or after his death, and dies leaving

such child unprovided for by any settlement, and neither provided

for nor in any way mentioned in his will, the child succeeds to the

same portion of the testator's real and personal property that he

would have succeeded to if the testator had died intestate. R.L.
