Certified Legal Transcription Services

A certified transcript carries a written declaration from the transcriber executed under penalty of perjury that the transcript is a true and accurate record of the source recording. In federal court and the majority of states, the declaration triggers Federal Rules of Evidence 902(11), which makes the document self-authenticating. The transcript can be offered into evidence without a sponsoring witness, provided reasonable written notice has been served on the adverse party and the record and declaration have been made available for inspection. A transcript that is simply signed by the transcriber, even on company letterhead, is not certified and will require a sponsoring witness at trial.

In federal court, no. Federal Rules of Evidence 902(11) accepts a written declaration under penalty of perjury without a notary jurat. In state court, the answer varies by jurisdiction. Texas Rule of Evidence 902(10), California Code of Civil Procedure § 2015.5, and Illinois Rules of Evidence 902(11) accept declarations without notarization. Florida § 90.902(11) and New York CPLR 4518 require a notarized affidavit. We default to a notarized affidavit on state-court filings because the marginal cost of notarization is low and a notarized declaration is admissible everywhere a bare declaration is admissible, while the reverse is not always true.

Roughly four to six hours of transcriber time for one hour of audio when the recording is clean and the speakers are distinct. Crosstalk, technical vocabulary, heavy accents, poor microphone placement, and multiple speakers extend that ratio meaningfully, sometimes to eight or ten hours per recorded hour. Certified work adds another layer: a second-reviewer pass against the source recording, hash verification, chain of custody logging, and affidavit execution. Typical turnaround at Legal Tank is two to five business days for a one-hour recording certified, with rush options for deposition-week and trial-week emergencies. We confirm the turnaround on quote, not after.

Not on certified work, and the reason is structural. Federal Rules of Evidence 902(11) requires a written declaration from a person who can attest under penalty of perjury that the transcript is a true and accurate record of the source recording. AI transcription tools (OpenAI Whisper, Google Speech-to-Text, Rev AI, Otter) cannot sign that declaration. They have no personal knowledge, they are not subject to perjury sanctions, and a transcript with an AI 'certifier' on the signature line will be excluded as not self-authenticating. AI is useful as a first-pass assist on long recordings, and we use it that way, but the certifier on every certified Legal Tank transcript is a human transcriber whose signature carries the affidavit.

No, for two independent reasons. First, ChatGPT does not transcribe audio on its own. Adjacent tools handle audio-to-text and average roughly eighty to ninety percent accuracy on clean recordings. Second, even if a perfect AI transcript existed, a certified transcript requires a written declaration under penalty of perjury executed by a person who reviewed the transcript against the source recording and has personal knowledge of the work. ChatGPT has neither personal knowledge nor legal capacity to swear an oath. The output of any AI tool can be the first pass, but the certifier on the affidavit must be a human transcriber. That is what makes the transcript admissible under Federal Rules of Evidence 902(11).

The terms are related but not interchangeable. A certified transcript carries a sworn declaration from the transcriber attesting that the document is a true and accurate record of the source recording. Authentication is the broader evidentiary doctrine of proving a document is what its proponent claims it to be, governed by Federal Rules of Evidence 901 and 902. A properly certified transcript under Rule 902(11) is self-authenticating, which means certification satisfies authentication without a sponsoring witness. A transcript that has been authenticated through a witness on the stand is not necessarily a certified transcript, and a certified transcript is not automatically admissible, since hearsay, relevance, and foundation rules still apply. The shortest correct framing: certification is the document Legal Tank produces; self-authentication is the legal result that document earns under Rule 902(11) in federal court and its state analogues.
