Illinois is a two-party consent state, or more precisely an all-party consent state: every participant in a private conversation must agree before anyone can legally record it. That puts Illinois in the minority of states that require more than one person’s permission, and it means the federal one-party consent standard does not save you if the conversation happens in Illinois. The rule comes from the Illinois Eavesdropping Act in Article 14 of the Illinois Criminal Code, and a first violation is a felony.
The All-Party Consent Rule
The Eavesdropping Act makes it a crime to knowingly and intentionally use any device to record or transmit a private conversation without the consent of all parties.1Illinois General Assembly. 720 ILCS 5/14-2 Being part of the conversation yourself does not change the analysis. If three people are talking and you want to record, all three have to agree, including you.
The statute specifically targets recording done “in a surreptitious manner.”1Illinois General Assembly. 720 ILCS 5/14-2 Surreptitious means hidden or secret. Openly setting a recorder on the table with everyone watching is treated differently from slipping a phone into your pocket with the microphone running.
What Counts as a Private Conversation
The all-party consent requirement only applies to “private conversations.” The statute defines that as an oral communication between two or more people where at least one party intended it to be private under circumstances that reasonably justify the expectation.2Illinois General Assembly. 720 ILCS 5/14-1
Setting drives the answer. A phone call, a closed-door meeting, or a conversation inside a home almost always qualifies as private, because the people involved chose a space where they reasonably expected not to be overheard. Shouting across a busy restaurant or speaking at a public meeting generally does not qualify, because the circumstances do not support any expectation of confidentiality. If the conversation is not private under this test, the Eavesdropping Act’s consent rule does not attach in the first place.
How to Get Valid Consent
The cleanest method is explicit consent before you start recording. Ask directly, get a yes, and then hit record. Written consent works too, which is why companies sometimes build recording clauses into contracts or terms of service.
Implied consent is recognized in some situations. The familiar example is an automated notice at the start of a phone call telling the caller the conversation may be recorded. If the other person stays on the line after hearing the notice, courts generally treat that as consent. The notification has to come before any substantive conversation, and it has to give the other party a real chance to hang up. Recording first and asking later does not satisfy the statute.
When Consent Is Not Required
The Eavesdropping Act lists specific situations where the all-party rule does not apply.3Illinois General Assembly. 720 ILCS 5/14-3 These exceptions are narrower than most people expect.
- Recording radio, television, or wireless communications that are publicly transmitted, and incidental recording of conversations at public functions, are not eavesdropping.
- Monitoring emergency transmissions from law enforcement, hospitals, and other emergency services in their normal operations is exempt.
- Certain security recording systems are allowed, but the recordings must be destroyed or turned over to law enforcement within 24 hours. Missing that deadline strips the exemption.
- Officers can record conversations with prior notification to the State’s Attorney in investigations involving forcible felonies, human trafficking, and similar serious crimes. A separate provision allows broader recording with formal State’s Attorney approval for qualified offenses, subject to time limits and other safeguards.
Notice what is not on that list. Illinois has no general exception for recording someone who is threatening you, harassing you, or committing a crime against you. Some states do. Illinois does not. If a caller is making threats and you want a recording for evidence, you are still bound by the all-party consent requirement unless a specific statutory exception fits.
Recording Police in Public
Recording on-duty police officers in public spaces is legal in Illinois, though the right comes from constitutional law rather than a carve-out in the Eavesdropping Act. The Seventh Circuit Court of Appeals held that the First Amendment protects the right to openly audio-record police performing their duties in public.4ACLU of Illinois. Victory for First Amendment Right to Audio Record Police Officers performing public duties in public places have a diminished expectation of privacy, and recording government conduct is treated as core protected expression.
The word “openly” carries weight. Visibly holding your phone up at a traffic stop is protected. Hiding a recorder in a squad car is not. And the Eavesdropping Act imposes harsher penalties for illegally recording law enforcement, prosecutors, and judges performing their official duties, which matters if the recording is not open.5Illinois General Assembly. 720 ILCS 5/14-4
Video Without Audio
The Eavesdropping Act governs oral and electronic communications. Silent video is handled under a separate statute, the unauthorized video recording law, which prohibits recording video of someone without consent in specific private settings: restrooms, locker rooms, changing rooms, tanning facilities, hotel bedrooms, and inside another person’s home.6Illinois General Assembly. 720 ILCS 5/26-4
Outside those protected locations, video-only recording with no sound generally does not trigger the Eavesdropping Act. A porch camera that captures picture but no audio is a common example. Add audio to the same camera, and the all-party consent rule kicks in for any private conversation it picks up.
Criminal Penalties
A violation of the Eavesdropping Act is a felony. Penalties escalate with repeat offenses and with the identity of the person recorded.
- A first offense is a Class 4 felony, carrying one to three years in prison.5Illinois General Assembly. 720 ILCS 5/14-4
- A second or subsequent offense is a Class 3 felony, carrying two to five years.7Illinois General Assembly. 730 ILCS 5/5-4.5-40
- Illegally recording a law enforcement officer, State’s Attorney, Attorney General, or judge performing official duties is a Class 3 felony on a first offense and a Class 2 felony on later offenses.5Illinois General Assembly. 720 ILCS 5/14-4
Fines of up to $25,000 can accompany any of those convictions. A Class 4 felony sits in the same category Illinois uses for offenses like aggravated assault and certain theft charges.
Civil Liability on Top
Someone who was recorded illegally can also sue. The Eavesdropping Act gives victims the right to recover actual damages and punitive damages.8Illinois General Assembly. 720 ILCS 5/14-6 Actual damages cover provable financial harm; punitive damages are awarded at the court’s or jury’s discretion for particularly egregious conduct.
Liability reaches beyond the person who did the recording. Landlords, building operators, and wire carriers who knowingly help or permit illegal eavesdropping can be held liable for the same damages.8Illinois General Assembly. 720 ILCS 5/14-6 A landlord who installs hidden recorders in a rental unit faces the same civil exposure as somebody who plants a bug directly.
Calls That Cross State Lines
Federal wiretapping law sets a floor of one-party consent, meaning only one participant has to agree.9Office of the Law Revision Counsel. 18 USC 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications The federal statute also notes that a recording made to commit a criminal or tortious act violating state law is not protected. Illinois’s stricter rule applies to conversations happening in Illinois regardless of what federal law would otherwise permit.
Interstate calls raise a harder question. If you are in Illinois talking to someone in a one-party state, courts have not settled uniformly which state’s law controls. Some courts have applied their own stricter rules when one participant was located there. The safe course is to follow the law of the stricter state. If one end of the call is in Illinois, treat the call as requiring all-party consent.
