Okla. Stat. tit. 12, § 12-587
General and special verdict
The verdict of a jury is either general or special. A general
verdict is that by which they pronounce generally upon all or any of
the issues, either in favor of the plaintiff or defendant. A
special verdict is that by which the jury finds facts only. It must
present the facts as established by the evidence, and not the
evidence to prove them; and they must be so presented as that
nothing remains to the court but to draw from them conclusions of
law.
