Okla. Stat. tit. 22 § 743
Upon a trial for having, with an intent to cheat or defraud another designedly, by any false pretense, obtained the signature of any person to a written instrument, or having obtained from any person any money, personal property or valuable thing, the defendant cannot be convicted if the false pretense was expressed in language unaccompanied by a false token or writing, unless the pretense, or some note or memorandum thereof, be in writing either subscribed by, or in the handwriting of the defendant, or unless the pretense be proven by the testimony of two witnesses, or that of one witness and corroborating circumstances. But this section does not apply to prosecution for falsely representing or personating another, and in such assumed character, marrying or receiving money or property.
