AI Notetaker Consent: What the Otter Case and All-Party Consent States Mean for Your Meetings

Federal law is a one-party rule: the federal Wiretap Act is satisfied if one person in the conversation consents, according to the Kilpatrick chart of wiretap laws. A group of states set a stricter rule and require every party to agree.

The lists do not match. Sources consistently name California, Florida, Illinois, Maryland, Montana, Pennsylvania and Washington. Connecticut, Delaware, Massachusetts, Michigan, Nevada, New Hampshire and Oregon appear on some lists and not others, depending on whether the recording is of a phone call or an in-person conversation. Published counts range from 11 to 14.

California is the state that matters most for cost. The Kilpatrick chart gives the remedy under the California Invasion of Privacy Act as $5,000 per violation or three times actual damages, whichever is greater. Many teams apply the strictest rule to every call for that reason.

A person in a meeting is a party to it. The open question is whether the software vendor is merely a tool used by one of the parties or a separate company listening in. Courts have split. One line of cases asks whether the vendor actually used the conversation for its own purposes. The other asks only whether it was capable of doing so.

Holland & Knight, reviewing these cases in May 2026, wrote that no bright-line rules have been established. The firm also warned that a standard notice that a call may be recorded may fall short where the complaint is about unannounced analysis by a third party happening at the same time.

In re Otter.AI Privacy Litigation combines four proposed class actions filed in August and September 2025 in the Northern District of California. On 13 August 2026 the court granted Otter's motion to dismiss in part and denied it in part. Claims under the federal Wiretap Act, the California Invasion of Privacy Act and the Illinois Biometric Information Privacy Act are proceeding.

Baird Holm's summary of the order says the court found the complaint plausibly alleged that Otter retained and used conversation data for its own commercial purposes. That allowed the plaintiffs to argue Otter acted as a third-party eavesdropper under California law. A ruling at this stage accepts the allegations as true. It does not find that Otter did anything unlawful.

The schedule reported by OpenClassActions puts the class certification motion on 13 May 2027 and a trial-setting conference on 1 December 2027. The research notes behind this article found no settlement, verdict or certified class in this or any other notetaker case. They relied on secondary summaries of the order, so check the docket.

The research counted roughly a dozen named cases, mostly against vendors. It found no case against an ordinary company whose employees simply ran a notetaker in meetings.

One allegation is worth reading closely. In Saucedo v. Sharp HealthCare, as described by Holland & Knight, patients allege that visits were recorded without consent and that the generated notes stated the patient had consented. If that is proved, the weak point was the record of consent itself.

On 13 January 2026 an Illinois federal court dismissed a federal Wiretap Act claim in Lisota v. Heartland Dental over an AI call service, applying the ordinary-course-of-business exception, as reported by Covington. On 23 June 2026 a California federal court granted summary judgment in Guerra v. Papa John's, holding that one section of the California law did not reach call centers that use internet calling, as reported by Loeb & Loeb.

On 22 October 2026 the court in the Google contact-center AI case dismissed one group of callers with leave to amend and sent three other groups to arbitration, according to OpenClassActions. The court treated lack of consent as something the plaintiff must plead.

These rulings are narrow. Each turns on a specific statute section, phone setup or set of accepted terms. They do not settle whether an AI vendor is a third party.

UC Today reports that Microsoft announced detection of external meeting bots in March 2026. The bots are labeled as unverified in the meeting lobby, the feature is on by default, and a tenant-level policy can block them automatically. General availability was reported for June 2026.

The same report says Zoom's AI Companion and Google Meet's note-taking feature must be started by a host and show an indicator, and that administrators can restrict them. These controls show that something is running. They do not record that each person agreed.

There is one gap. Baird Holm notes that tools which capture audio on the device, with no bot joining the call, cannot be seen or blocked by meeting-platform bot controls. A written policy has to cover those tools.

Law firms advising on the Otter case describe the questions a court will ask: did every participant get notice before recording began, and what does the vendor do with the data. Which rule applies to a given meeting is a question for counsel.

• Put the notice in the calendar invitation, naming the tool and saying that an AI service will transcribe the meeting.
• Keep the notetaker out until the host has said the same thing aloud and asked whether anyone objects.
• If anyone objects or joins late without hearing the notice, stop the tool or ask again.
• Check the vendor's settings for retention and for model training on your conversations, and record what you chose.
• Save a dated note of who was present, what they were told and what they said.
