State recording laws — a qualitative overview for PIs

Recording a phone conversation is regulated at both the federal and state level. The federal floor (18 U.S.C. § 2511) is one-party consent — at least one party to the conversation must consent. A significant number of US states impose stricter requirements, generally referred to as all-party consent or two-party consent.

This post is a qualitative overview of how this lands for private investigators conducting intake calls. None of it is legal advice — recording law is exactly the kind of jurisdiction-specific area where the firm should consult counsel before setting a recording policy. The goal here is to give an investigator enough vocabulary to ask the right questions.

For an authoritative current map of state recording laws, see the Reporters Committee for Freedom of the Press guide (TODO(confirm): https://www.rcfp.org/reporters-recording-guide/) and the National Conference of State Legislatures summary (TODO(confirm): https://www.ncsl.org/technology-and-communication/recording-laws).

One-party vs all-party

One-party consent means a single party to the conversation may record without notifying the others. The party doing the recording counts as that one party. This is the federal floor and the rule in most US states.

All-party consent (sometimes called two-party consent, though the term is misleading when more than two parties are on the call) means every party must consent to the recording. The investigator cannot record without an explicit disclosure and consent.

The states that follow all-party consent include several large ones — California, Florida, Illinois, Massachusetts, Pennsylvania, Washington — though the exact list and the specific scope vary, and some states apply different rules to in-person vs phone vs cellular conversations. Always check the current law for the relevant jurisdiction.

Why "the call's location" is fuzzy

The complication for a PI firm is that the intake call can involve multiple jurisdictions. The investigator is in one state. The caller may be in another. The subject of the investigation is in a third. The cellular tower the call routes through is in a fourth.

Most state recording statutes apply when at least one party is in the state at the time of the recording. So a call where the caller is in California and the investigator is in Texas may need to comply with California's all-party consent law — California is the stricter jurisdiction, and one party is there.

The defensive practice is to assume all-party consent applies to every intake call, regardless of the parties' locations. This means every intake call opens with a recording-consent disclosure and an affirmative consent capture.

What "consent" looks like in practice

The minimum standard is:

1. A clear disclosure that the call is being or may be recorded, given at the start of the call before any substantive conversation.
2. A request for explicit consent, not implied consent.
3. A capture of the caller's response (verbal "yes" is typical).
4. A documented retention policy for both the recording and the consent.

The disclosure should not be buried in a long greeting. The caller should hear "this call may be recorded for our case-management records — is that OK with you?" within the first 10 seconds, before they've shared any case details. If the caller declines, the call continues without recording (or, depending on the firm's policy, the agent informs the caller that the firm only handles intake on recorded calls and offers them an alternative — typically a callback from a human investigator on a non-recorded line).

What about the subject of the investigation?

The intake call is between the investigator (or the firm's intake agent) and the prospective client. The subject of the investigation is not on that call and the recording laws apply to the parties on the call, not the people being discussed. The intake doesn't require the subject's consent.

Recording calls to the subject — interviews, pretext calls in the limited contexts where those are permissible — is a different question entirely. The recording laws apply there, and the consent requirements apply to the actual parties to that call. Pretexting for financial information is independently prohibited under GLBA regardless of recording-law considerations.

Recordings as evidence

If the intake recording or a follow-up recording may ever be used as evidence in a proceeding, additional considerations apply. The chain of custody for the recording matters. The format and metadata should be preserved. The recording should not be edited.

Indagor stores intake recordings in their original format with cryptographic hashes for tamper evidence. The recording, the hash, the transcript, and the metadata are all retained per the firm's records-retention policy.

What this changes for the firm

A firm with a disciplined recording-consent practice has a defensible record for every intake. Exams, complaints, and discovery requests all become straightforward — the firm can produce the recording, the consent, the script, and the retention metadata.

The opposite — a firm with informal or inconsistent recording practices — has an exposure surface that grows with every call. The exposure may not materialize for years, but when it does, it tends to be expensive.
