How to Prepare for a Deposition: A Guide for Attorneys

1. Know the Case Inside Out

It may sound pretty obvious, but the first step to preparing for any deposition is having a complete handle on the case. That starts with a careful review of pleadings, discovery responses, and prior motions.

Go deeper than a quick skim. Study the details, flag contradictions, and track statements that could be tested during testimony. A thorough review of documents also helps you predict how the opposing attorney may shape their questioning strategy.

Once you’re grounded in the record, put together a deposition outline. The goal is to map out the key facts, themes, and exhibits you want to cover. This gives you structure while leaving room to adjust based on how the witness is answering questions.

Keep in mind that the stronger your case knowledge, the sharper your questioning, and the cleaner the record you’ll create for trial.

If you want to cut down on weeks of manual review, Briefpoint’s upcoming tool Autodoc is built for exactly that. It auto-drafts discovery responses with Bates citations in seconds, packaging ready-to-serve productions.

2. Analyze the Witness

Witness preparation starts with knowing who you’re dealing with. Take time to study the witness’s professional and personal background, prior deposition testimony, and any sworn testimony given in other cases.

This groundwork helps you anticipate credibility issues, potential biases, and the perspective they’ll bring to questioning. Plus, careful preparation not only sharpens your approach but also helps you feel confident when it’s time to examine them.

Here are a few deposition tips to guide your analysis:

• Review documents and written discovery connected to the witness to test consistency.
• Focus on only the question you need answered so responses stay within the scope of their personal knowledge.
• Compare deposition testimony with other sworn statements to identify contradictions.
• Study other witnesses and expert witnesses to understand how their accounts may align or conflict.
• Consider motivations, such as professional, personal, or financial, that may influence answers.

Thorough analysis like this turns witness preparation into a clear strategy. It allows you to approach the deposition with precision and keep testimony focused on what strengthens your case.

3. Draft an Outline, Not a Script

A deposition outline is extremely important because it gives structure to the process without locking you into a script.

You don’t need to write out every single question. Instead, use it to group topics so you can gather information in a clear, logical way. That makes it easier to discuss key issues while still leaving room to follow up when a witness says something unexpected.

A solid outline keeps the legal case on track but is flexible enough to adjust as things unfold. Here’s an example outline you might use:

• Background
  • Confirm name, role, and relationship to the legal case
  • Discuss education, employment, or professional history
• Key events
  • Walk through the timeline of events step by step
  • Attempt to pin down dates, times, and locations
  • Clarify the witness’s personal involvement and knowledge
• Documents
  • Review documents already produced in written discovery
  • Ask the witness to explain or authenticate exhibits
  • Compare their deposition testimony with prior statements
• Damages or impact
  • Explore financial, physical, or reputational effects
  • Gather information on any claims for compensation

An outline like this keeps your questioning sharp and adaptable. In other words, it can help make sure the deposition flows smoothly while covering what matters most to the case.

4. Master the Exhibits

Managing exhibits is one of those steps that can make or break how smoothly a deposition runs. As the lawyer, you should expect the other side to bring their own set of documents, so being organized with yours gives you the upper hand.

Don’t just stack papers in a folder. Tab and arrange them so you can present each piece of evidence quickly and tie it back to your case theory.

Here are a few examples of legal documents you might include:

• Contracts or agreements at the heart of the lawsuit
• Emails or written communications that show what was said and when
• Internal reports or financial records that connect facts to damages
• Photographs or diagrams to present context in a way a jury could easily understand later
• Prior sworn testimony or discovery documents to compare with the witness’s current answers

Exhibits are the backbone of the evidence you’ll build your record on. So, the more prepared you are, the more confident you’ll be when it’s time to walk the witness through them.

5. Conduct Witness Preparation

When your own client is the one being deposed, preparation is just as important as knowing the law.

First things first, walk them through the deposition process step by step and make sure they fully understand what to expect from the other attorney’s questioning.

Emphasize that their role is to listen carefully, answer only what’s asked, and avoid volunteering information that goes beyond the question.

Additionally, remind them that privileged information is protected, and they should pause if there’s any doubt so you can object on the record.

For example, if the opposing lawyer asks, “Were you present at the meeting on June 5th?” the correct answer is simply “Yes” or “No.” Adding details like who else attended or what was said (unless directly asked) creates unnecessary risk.

Running a mock deposition ahead of time is a great way to show your client how quickly answers can spiral if they don’t stay focused. With the right preparation, your client walks in calm, clear, and ready to give testimony that supports the case without giving away more than they should.

6. Anticipate Opposing Counsel’s Strategy

This part of deposition prep can be tricky because you’re planning for moves the other side hasn’t made yet. The key is to think through what their goals might be.

Some lawyers will focus on impeachment, hoping to catch your witness in a contradiction. Others will try to uncover new facts that weren’t addressed in written discovery. Still others may be laying the groundwork for trial testimony and locking in answers they can later present to a jury.

Preparation means looking at the case from their perspective. Review pleadings, prior deposition testimony, and document requests to see where they may try to push.

From there, prepare objections you may need to raise, such as form, privilege, or relevance, and be ready to step in quickly if questioning crosses the line. Keeping these possibilities in mind makes sure you can guide the deposition back to safe ground without breaking the flow of testimony.

Remember: A smart lawyer doesn’t just react during questioning. They expect the other side’s strategy and prepare responses in advance. That way, you’re not scrambling when the pressure is on.

7. Focus on Style as Much as Substance

The way you ask questions can be just as important as the substance behind them. A clear, deliberate style helps keep the record clean and makes it harder for the witness to sidestep the truth.

Good technique also limits the need for objections and keeps the deposition moving smoothly. Here’s some practical advice to keep in mind:

• Start with open-ended questions when you need to gather facts and hear the witness’s version of events in their own words.
• Switch to short, clear questions when pinning down specifics so there’s no confusion about the question asked.
• Avoid compound questions that mix multiple points together, since they create opportunities for vague or incomplete answers.
• Save leading questions for situations where the circumstances call for control, such as clarifying prior testimony.
• Follow up with clarification whenever an answer is unclear, incomplete, or inconsistent with documents or other testimony.

This approach keeps the record stronger, ties testimony more closely to the facts, and gives you more reliable material to use later in the case.

8. Plan for the Record

This one might feel like a no-brainer, but then again, it’s easy to forget in the middle of a tense deposition. Every word spoken can show up at trial, so the way you phrase questions and manage tone matters just as much as the substance.

Keep your language professional, avoid unnecessary back-and-forth with the opposing attorney, and frame each question so it reads cleanly on the transcript. A deposition is a written record in the making, and that record can become a powerful tool for or against your case.

9. Logistics and Ethics Check

Logistical planning may feel routine, but it’s just as important as witness prep or drafting a deposition outline.

The basics (date, time, location, and court reporter) need to be confirmed so everyone involved knows what to expect. Never assume these details will handle themselves; they should be verified ahead of time to avoid unnecessary delays or confusion.

On the ethics side, it’s critical to protect privilege and confidentiality throughout the deposition process. If an issue comes up, you should be ready to consult the rules, refer to agreements made during discovery, and respond appropriately on the record.

In certain circumstances, the dispute may require guidance from a judge, so anticipating these challenges ahead of time will save time and keep the deposition moving forward.

Key points to cover include:

• Confirming the date, time, and location of the deposition
• Verifying that a court reporter is scheduled and available
• Making sure all persons involved are properly notified and prepared
• Addressing privilege and confidentiality protections before questioning starts
• Preparing how you’ll respond to disputes, from objecting to consulting the rules
• Knowing when to refer the issue to the judge if it can’t be resolved in the room

10. Debrief and Follow Up

Lastly, don’t let the deposition end when the witness leaves the room. After the deposition, take time to review the transcript carefully.

Go through each section to spot key admissions, inconsistencies with prior testimony, and areas where the witness may have opened the door for additional questions. Flag anything that could support motions, impeachment at trial, or new lines of written discovery.

This step also gives you a chance to consult with your team, compare notes, and decide how the testimony fits into the larger legal case.

Following up right away keeps the details fresh and makes it easier to decide whether you need another deposition, additional documents, or a motion to compel.

Plus, treating the debrief as a routine part of the process strengthens your strategy and makes the entire deposition effort more valuable in the long run.
