Attorney-client privilege is one of the foundational principles of legal practice. Before using any AI tool to transcribe client calls, law firms must understand exactly how privilege intersects with third-party data processing.
Does Using AI Transcription Waive Privilege?
Generally, no — using a third-party service provider to process privileged communications doesn't waive attorney-client privilege, provided that: the service is used for a privileged purpose, the provider has adequate confidentiality protections, and the disclosure is limited to what's necessary.
This is similar to using a court reporter, a translation service, or a document management platform. The privilege survives as long as you take reasonable steps to maintain confidentiality.
What "Reasonable Steps" Look Like
- Select a provider with explicit confidentiality agreements and DPA
- Ensure data isn't used to train AI models
- Implement access controls limiting who can view transcriptions
- Have a data retention and deletion policy
- Inform clients how their communications are processed
Bar association guidance: check your jurisdiction's specific rules. Several bar associations (including the ABA) have issued formal opinions permitting cloud-based legal tools with appropriate safeguards.
Client Informed Consent
Best practice — even if not strictly required — is to inform clients that their calls may be transcribed using AI tools, who processes the data, and how it's protected. This eliminates any privilege waiver argument and builds trust.
