The Deposition Interpreter Checklist Every Litigation Team Should Use

By: Jilio-Ryan | Posted in: Legal Interpreters

A deposition scheduled around a witness who does not speak fluent English can go sideways fast if the interpreter is not properly qualified, or the wrong dialect shows up in the room. Opposing counsel can challenge the testimony. A judge can grant a continuance. Weeks of preparation can unravel over one detail confirmed too late, or not confirmed at all. Most of what protects a deposition from that outcome comes down to a handful of things litigation teams can lock into standard deposition preparation, well before the deposition date.

Confirm the Interpreter Is Properly Certified

A legal deposition interpreter needs more than fluency in two languages. Being bilingual and being a certified interpreter are not the same qualification. Certification tests specific skills, simultaneous and consecutive interpreting, sight translation, and command of legal terminology, under exam conditions set by the relevant state certifying body.

Certification tiers and the terms used to describe them vary by state and can change as certifying bodies update requirements. Rather than assuming a label from one jurisdiction applies everywhere, confirm the interpreter’s current, verified status directly with the certifying body or the interpreting agency before the deposition.

Match the Language and Dialect, Not Just the Language

Requesting a “Spanish interpreter” or a “Mandarin interpreter” is not specific enough. Regional dialects, formality levels, and even the type of sign language used, American Sign Language versus a foreign sign language, can differ enough to affect comprehension during testimony.

Confirm the exact language variation with the witness or their counsel directly, rather than relying on a general request to an interpreting agency. A brief phone call before booking can catch a mismatch that would otherwise surface for the first time at the deposition table.

The Interpreter Checklist

Before the deposition date, confirm each of the following:

• Certification confirmed for the relevant jurisdiction and proceeding type
• Language and dialect matched to the deponent, confirmed in advance
• Interpreter booked with enough lead time, well before the notice deadline
• Interpreter briefed on subject matter or terminology in advance, where possible
• Remote versus in-person format decided and tested ahead of time
• Backup plan in place if the interpreter cancels

Remote Interpreting: What Changes

The certification standard does not change when a deposition moves to a remote format. A certified interpreter is still required, regardless of whether everyone is in the same room or connecting from different locations across the country.

Remote settings add a few practical considerations: connection quality strong enough to support real-time interpreting, a plan for screen-sharing exhibits through the interpreter without losing meaning, and confirmation that every party agreed to the remote format in advance, not just the interpreting agency.

What Happens If This Gets Missed

Skipping any of these steps carries real risk. An uncertified or mismatched interpreter can be challenged by opposing counsel, sometimes mid-deposition, putting the reliability of the testimony itself in question.

In some cases, this leads to the deposition being rescheduled or portions of the testimony being redone with a qualified interpreter. That means added cost, delay, and a weaker record than the case needed. None of this is guaranteed, but it is avoidable.

Building This Into Your Deposition Workflow

The most reliable way to avoid these issues is to treat interpreter confirmation as a standard step in deposition preparation, not an afterthought handled once other logistics are set. Confirm the interpreter alongside the court reporter and videographer, at the same time, as part of the same booking conversation.

Litigation teams that build interpreter confirmation into their regular court interpreter services checklist, working with certified legal interpreters as a matter of course, tend to catch language and certification issues early, while there is still time to fix them.

Confirm the Interpreter, Confirm the Deposition 

A properly certified, correctly matched interpreter is one of the easiest things to confirm well before a deposition, and one of the most damaging to overlook. Building it into your standard workflow protects the record and keeps the proceeding on schedule.

FAQs

1. How far in advance should a certified interpreter be booked? 

Lead time varies by language, certifying body, and interpreter availability, so there’s no universal rule. As a general practice, confirm the interpreter well before your notice deadline, not at the last minute.

2. What’s the difference between a certified and a registered interpreter?
 Terminology varies by state, but certified interpreters have generally passed a full exam in interpreting technique and legal terminology, while registered interpreters have met a different qualifying standard, often for languages without a certification exam. Confirm current terms with the relevant certifying body.

3. Can an interpreter appear remotely for a deposition?
 Yes, as long as all parties agree to the remote format in advance and the interpreter meets the same certification standard required in person.

4. Who is responsible for confirming the interpreter’s certification, the requesting attorney or the reporting agency?
 This varies by firm and agency, so it’s worth confirming directly rather than assuming. Many teams treat it as a shared check, confirmed by the agency at booking and verified again by the attorney’s office.
