How to Translate Legal Documents
Without Losing Attorney-Client Privilege
Your client's deposition transcript needs to go to a witness in Mexico City. The contract is in Mandarin and your client needs it in English by Friday. You open Google Translate, paste the text, and move on. What you may not realize: you just sent privileged client information to a third-party server with no retention guarantee, no attorney-client privilege waiver analysis, and no ethical review.
- Google Translate may use submitted text to improve its models (per their Terms of Service)
- DeepL Free stores documents temporarily on EU servers — creating cross-border data transfer issues
- ChatGPT retains conversation history by default unless you opt out
- Most consumer AI tools have no HIPAA, CIPA, or legal privilege protections
- Pasting privileged content into a third-party service may constitute inadvertent disclosure
What the ABA Says About AI Translation Tools
ABA Formal Opinion 512 (2023) directly addressed attorney use of generative AI tools. The opinion confirms that attorneys have obligations under Model Rules 1.1 (competence), 1.6 (confidentiality), and 5.3 (supervision of non-attorneys) when using AI tools that process client information.
Specifically, attorneys must make reasonable efforts to prevent inadvertent or unauthorized disclosure of client information — which includes understanding whether the AI tool retains, trains on, or shares the data submitted to it. Using a consumer-grade translation tool without reviewing its data practices is, at minimum, a competence issue under Rule 1.1.
The 4 Document Types Most at Risk During Translation
What "Zero Retention" Actually Means
Not all "privacy-focused" translation tools are equal. The key distinction is between tools that "delete" your data after a period and tools that are architecturally incapable of retaining it.
Promise-based retention: "We delete your data within 24 hours." This still means your data was stored, logged, potentially backed up, and accessible to employees during that window.
Architecture-based retention: The text is sent to an API endpoint, translated in-transit, and returned — with no write operation ever occurring on a storage medium. There is literally nothing to delete because nothing was ever stored.
The latter is the only approach appropriate for privileged legal documents. It's also what ShieldDrop's LegalTranslate is built on — text flows through the AI translation API and is returned to you. Our infrastructure has no write path for document content.
Practical Guidelines for Attorneys Needing Translation
Review the translation tool's Terms of Service specifically for data retention and training clauses before using it with client data.
Never paste full deposition transcripts, medical records, or unredacted contracts into consumer tools like Google Translate or ChatGPT.
For documents containing HIPAA-protected health information, confirm the translation service has a signed BAA before proceeding.
If your firm uses a certified human translator, confirm they've signed an appropriate NDA and confidentiality agreement.
Document your translation workflow in your file — showing you took reasonable steps to protect privilege is important if inadvertent disclosure is ever alleged.
LegalTranslate supports 30+ languages and preserves legal terminology, citation formatting, and document structure. Text is processed in-transit — nothing written to any server.

Translation is no longer a niche need — with international clients, foreign-language witnesses, and cross-border contracts becoming routine, most litigators will need to translate privileged documents at some point. The question isn't whether to translate — it's whether you've thought through the ethical implications of how you do it.
The standard is "reasonable measures" — and reasonable measures in 2026 means not pasting your client's deposition transcript into a consumer tool that trains its models on user input. Purpose-built, zero-retention tools exist. They take 30 seconds to use. Use them.
