This chart sets forth the applicable law regarding whether telephone conversations may be lawfully recorded. Remember that unless the caller and the called party are in the same state - then only that state's law would apply - the interstate call actually implicates three bodies of law, federal law, the law of the calling-party's state, and the law of the called- party's state. Each law must be obeyed.

The federal statute convering the interception and disclosure of wire communications is codified at 18 U.S.C. § 2511. The statute is the blueprint for many of the state statutes in this area of the law. It requires one-party consent and states it is not unlawful "for a person not acting under the color of state law to intercept a wire, oral, or electronic communication where such person is a party to the communication or where one of the parties to the communication has given prior consent to such interception unless such communication is intercepted for the purpose of committing any criminal or tortuous act in violation of the Constitution or laws of the United States or of any state." 18 U.S.C. §2511(d).

As to the individual states, each can be grouped in one of two categories. Specific statute citations for each state follow.

A further explication of the relevant law is as follows:

Alabama	Ala. Code § 13A-11-30(1)	The Statutory definition of eavesdropping excludes the recording of a conversation with the consent of one party. Thus, the citizen has a right to record his own conversations.
Alaska	Alaska Stat. §§ 42.40.300(a) & 42.20.310(a)(1)	Statute does not prohibit the use of an eavesdropping device to record a private conversation when there is the consent of "a party to the conversation." Accord Palmer v. State , 604 P. 2d 1106, 1108 n. 5 (Alaska 1976)(finding the statute was clearly intended to prohibit third-party eavesdropping and is not applicable to a situation where one of the participants recorded the conversation.)
Arizona	Ariz. Rev. Stat. Ann. § 13-3005	A party is not prohibited from intercepting oral communications.
Arkansas	Ark. Code Ann. § 5-80-120(a)	It is lawful to record a communication if one is a party to the communication or has received the prior consent of a party to the communication.
California	Cal. Penal Code § 632(a)	Statute prohibits the recording of confidential communications without "the consent of all parties." Evidence obtained in violation of this section may not be used in any judicial proceeding. This prohibition is confined to confidential communications, defined by statute as "any communication carried on in circumstances as may reasonably indicate that any party to the communication desires it to be confined to the parties there to," but does not include communications made under any "circumstance in which the parties to the communication may reasonably expect that the communication may be overheard or recorded."
Colorado	Colo. Rev. Stat. § 18-9-303(1)	Statute does not prohibit the recording of a conversation by either a "sender or intended receiver" of a telephone communication.
Connecticut	Conn. Gen. Stat. Ann. § 52-570d(a)	Statute creates a civil cause of action for any person whose telephone conversation is recorded unless the person recording the conversation received the "consent of all parties to the communication." Consent must be obtained either in writing or at the beginning of the recorded conversation."

Illinois	720 ILS 5/14-2"(a)	Statute prohibits recording a telephone conversation without the consent of "all parties to [the] conversation." But, Illinois courts have found that the recording of a conversation by a party to the conversation is not a violation of the statute even if another party to the conversation is unaware of the recording. People v. Jansen, 561 N.E.2d 312, 314 (Ill. App. Ct. 1990).
Indiana	Ind. Code Ann. § 35-33.5-1-5(2)	Statute allows the recording of a telephone conversation by either the sender or receiver of the communication

South Carolina	No state statute	South Carolina does not have a state statute on its books that regulates the interception of phone conversations. But, South Carolina case law indicates that when such issues arise in South Carolina courts, the courts will look to 18 U.S.C §2511. the federal statute on the interception and disclosure of wire communications. Under 18 U.S.C. §2511(2)(d), it is lawful to intercept a communication if one is a party to the communication or has received the prior consent of a party to the communication. See Mays v. Mays, 229 S.E.2d 725, 726-27 (S.C. 1976) (finding that 18 U.S.C. §2511(2)(d) "makes it clear that one party to a telephone conversation may lawfully tape the conversation without the other's knowledge or permission and subsequently disclose [the conversation]."); Thompson v.

Vermont	No state statute	There is no state statute on the books regulating the interception of telephone conversations. The case law is sparse in this area and has not yielded a clear indication of whether Vermont is a one-party or two-party consent state. In one case, the court indicated, without deciding the issue, that the federal statute on interception and disclosure of wire communications (18 U.S.C. §2511) was applicable in the state setting. State v. Fuller, 503 A. 2d 550, 551 (Vt. 1985) . The federal statute permits one party to a communication to intercept the communication. Another Vermont case indicates that, in a criminal setting , challenges to recorded conversations may be made on Fourth, Fifth, and Sixth Amendment grounds. State v. Kasper, 404 A.2d 85, 92-93 (Vt. 1979).

Wyoming	Wyo. Stat. §7-3-602(b)(iv)	It is lawful to intercept a communication if one is a party to the communication or has received the prior consent of a party to the communication.
