Below is a section of the Oklahoma State Statutes that we believe apply to recording phone conversations. This information is not intended as a substitute for legal counsel.
From the Oklahoma State Code
Okla. Stat. tit. 13, § 176.4: Anyone who is a party to a wire, oral or electronic communication or who has obtained consent from a party can lawfully record or disclose the contents of that communication, so long as he does not do so in furtherance of a criminal act.
Under the statute, consent is not required for the taping of a non-electronic communication uttered by a person who does not have a reasonable expectation of privacy in that communication. See definition of "oral communication," Okla Stat. tit. 13, § 176.2.
Unlawful recording or disclosure is a felony punishable by a fine of not less than $5,000 and jail time not to exceed five years. Okla. Stat. tit. 13, § 176.3.
Oklahoma law also makes it a misdemeanor to secretly loiter about a building with intent to hear discourse therein and repeat or publish it. Okla. Stat. tit. 21, § 1202.
It is always best to talk with an attorney if you have questions about the legal implications of recording calls in your state. We hope this information will serve as a general guide, and is not intended to substitute for expert legal counsel.
