Law firms have good reasons to record and carefully manage phone calls — client intake, billing accuracy, dispute documentation. Illinois’ eavesdropping law makes getting the consent side right a genuine legal risk, not a courtesy that’s nice to get right.
The Law Is Stricter Than Most Firms Assume
Illinois is an all-party consent state under 720 ILCS 5/14-2, meaning recording a private conversation without the consent of every participant can constitute criminal eavesdropping, not just a civil or ethical violation. This applies even to interstate calls where one party is located in Illinois, which matters for firms handling matters or clients across state lines.
What Makes a Recording Illegal
The law requires two elements: the recording must be made surreptitiously, hidden or without the other party’s knowledge, and the conversation must be “private,” meaning at least one party intended it to be private and the circumstances objectively supported that expectation. A firm that discloses recording openly and gets acknowledgment doesn’t meet the surreptitious element and is generally in the clear.
How Firms Get Consent in Practice
Most firms use an automated disclosure message at the start of a call, something like “this call may be recorded for quality and training purposes,” and by continuing the conversation after hearing that notice, the other party generally provides implied consent. This needs to be configured consistently across every line that records calls, not applied selectively depending on who happens to remember.
Privilege Doesn’t Disappear Because It’s Audio
A recorded privileged conversation needs the same confidentiality protections as any other form of privileged communication — storage, access controls, and retention of recordings need to meet the same standard firms apply to written client communications, not a lower bar just because the format is audio. Client voicemails deserve the same treatment: they often contain confidential or privileged information, and a voicemail system without encryption or access restrictions is a real gap in an otherwise secure firm communication setup.
The Risk-Management Upside
Recorded calls provide a clear, verifiable record of what was actually discussed and agreed to during client conversations, reducing disputes over billing time, scope of engagement, or what advice was actually given. This is a genuine benefit for firms, provided the recording program itself is run in a legally compliant way — the protection only holds up if the recording itself was legal to make.
Consistency Beats Selective Recording
Most firms benefit from a consistent policy rather than ad hoc, selective recording. A documented policy about which lines or call types get recorded, with the disclosure consistently played, reduces both compliance risk and the appearance of selectively recording calls in a way that could later be questioned by opposing counsel.
Don’t Forget E911
If a firm operates a multi-line telephone system across an office, particularly a multi-floor office, Kari’s Law and RAY BAUM’S Act apply the same way they would to any other business. See our E911 compliance guide for what’s required.
Multi-State Firms: Default to the Strictest Standard
Given that Illinois’ all-party consent requirement can apply to interstate calls involving an Illinois party, and other states have varying consent rules of their own, the safest approach for a multi-jurisdiction firm is obtaining all-party consent on every call regardless of where the other party is located, rather than trying to track which specific rule applies call by call.
