A deposition transcript becomes part of the evidentiary record and can later be used to challenge or impeach testimony given at trial if it's inconsistent, so how a question is answered matters as much as what is said.

There's no benefit to rushing through answers or filling silence to seem cooperative. Taking a moment to fully understand each question before responding generally produces more accurate, defensible testimony.

Guessing at an answer, speculating about facts outside your direct knowledge, volunteering extra information beyond what was asked, and arguing with opposing counsel are among the most common ways witnesses undermine their own testimony.

Answering a question you don't fully understand is another frequent mistake. It's generally fine, and often expected, to ask for a question to be clarified or repeated rather than guessing at its meaning.

If you genuinely don't know or don't recall something, saying so plainly is the appropriate and honest response, rather than reaching for an answer that sounds more complete or helpful than what you actually remember.

Witnesses are also generally permitted to ask that a question be repeated or clarified before answering, and to take breaks when needed, rather than pushing through confusion or fatigue.

Reviewing likely topics and documents with your attorney before the deposition helps you anticipate the kinds of questions you'll face and refresh your memory on relevant facts.

Understanding how objections work during a deposition, and that most objections don't excuse you from answering, helps avoid confusion in the moment about whether and how to respond.
