A large share of consumer legal clients are more comfortable in a language other than English, and firms handle that badly. The common approaches are refusing those cases, relying on a client’s teenage relative to interpret, or having one overworked bilingual staff member become the bottleneck for every conversation.
AI changes the economics enough to matter, as long as you are precise about which tasks it is allowed to do.
What it handles well
Understanding an incoming document. A client hands you a contract, a repair order, or correspondence in Spanish and you need to know what it says. AI translation is fast, cheap, and good enough to make a decision about the matter. This is the highest-value use because the alternative is often not reading it promptly at all.
Routine client communication. Status updates and general correspondence, translated and then reviewed by a bilingual person before sending. The client update workflow works the same way in either language.
Intake at first contact. Someone reaching your firm in Spanish at 8pm should get a response in Spanish. Meeting them in their language at the first touch changes whether they engage at all, which ties directly into the intake process.
Internal comprehension. Recorded calls, notes, and messages from a client that your English-speaking team needs to understand. Combined with transcription, a Spanish voicemail becomes an English summary in the file automatically.
Website and marketing content, with human review.
What it cannot do
Certified translation. Courts, immigration authorities, and opposing parties require a certification from a qualified translator attesting to accuracy. That attestation is the product. There is no AI equivalent, and there will not be one soon, because the point is that a person with credentials is accountable for it.
Signed client agreements. A retainer or a settlement release in a language the client relies on must be translated by a qualified human. If a dispute ever arises about what the client understood, “we used AI” is not an answer you want to give.
Court filings and evidence.
Live interpretation for testimony. Depositions and hearings require a certified interpreter, full stop.
Anything where a subtle error changes the meaning of an obligation. Legal terminology does not map cleanly across legal systems. A word that translates literally can carry different legal weight in the other jurisdiction, and fluent output hides that better than clumsy output does.
The line to draw
| Task | AI alone | AI plus bilingual review | Certified human |
|---|---|---|---|
| Understanding an incoming document | Yes | Better | Only if it becomes evidence |
| Routine status update to a client | No | Yes | No |
| First response to an inquiry | Yes | Better | No |
| Explaining settlement terms | No | No | Yes |
| Retainer or fee agreement | No | No | Yes |
| Court filing or exhibit | No | No | Yes |
| Live testimony | No | No | Yes |
Making it work in practice
Give the model the context. “Translate this for a Spanish-speaking client in California with no legal background, at an eighth grade reading level, keeping the legal terms accurate” produces something usable. “Translate this” produces something stiff and often too formal for the reader.
Watch regional variants. Spanish for a Mexican-American client in Los Angeles and Spanish for a Colombian client are not identical in vocabulary or register, and the difference is noticeable to the reader even when the meaning is intact. Tell it which audience.
Keep a glossary. Your practice area has recurring terms, and you want the same translation every time. Loading a short glossary into a Project keeps that consistent across everyone at the firm.
And have a bilingual person spot-check the output regularly, not just the first week. The failure mode is fluent and wrong, which reads perfectly well to someone who does not speak the language.
Do this today
Take the document your firm sends most often to clients, likely an intake confirmation or a status update template. Have it translated by AI, then have a bilingual staff member or a professional review it once.
Now you have a reviewed template rather than a one-off translation, and every future send in that language is a review rather than a translation job.
