How to Draft Interrogatories for Better Discovery

What Are Interrogatories?

Interrogatories are written questions one side sends to the other during the discovery process in a lawsuit. They are one of the most common discovery requests used to gather basic facts, pin down positions, and get details that the other side may rely on later.

When you serve interrogatories, the receiving party has to answer them in writing and under oath. Those answers usually cover names, dates, events, documents, damages, and other requested information tied to the claims or defenses in the case.

In some situations, interrogatories also ask a party to identify witnesses, describe how an incident happened, or explain the basis for certain allegations.

Attorneys often use interrogatories early in discovery to get a clearer picture of the case before depositions or other follow-up steps. They can help you sort out what the other side is claiming, what facts are still unclear, and which issues may need closer attention.

And unlike depositions, interrogatories happen in writing, so there is more time to prepare responses carefully. That makes them useful when you want direct answers you can review, compare, and use to build the rest of your discovery plan.

How to Draft Interrogatories Step by Step

If you want stronger answers, it helps to be deliberate with how you frame each question. Here are the steps that can help you draft interrogatories more clearly and strategically:

1. Review the Pleadings, Case Files, and Related Document Requests

Before you draft anything, take a close look at the pleadings and the case file.

To start, this gives you a better sense of what the case is really fighting over, what facts are still missing, and what the other side has already said on the record. It also keeps you from writing questions that are too broad or disconnected from the actual dispute.

From there, read through the complaint, answer, counterclaims, affirmative defenses, and any early disclosures or emails that help fill in the story. Look for vague allegations, missing dates, unclear timelines, and statements that raise follow-up questions.

It also helps to check your existing records at this stage. Some facts may already be sitting in the file, so there is no reason to spend interrogatories asking for them again.

At the same time, this review helps lawyers keep the scope of the questions tight. When your interrogatories line up with the actual claims and defenses, they are more useful and harder to attack.

What to review:

• Complaint
• Answer
• Counterclaims
• Affirmative defenses
• Initial disclosures
• Prior correspondence
• Key documents
• Existing records
• Missing facts
• Disputed issues

2. List the Facts You Still Need

Once you have reviewed the file, the next step is figuring out what facts are still missing. That means looking at the case from both sides and asking yourself what you still need to obtain before you can fully evaluate the claims, defenses, and timeline.

For example, the plaintiff may have alleged harm without giving much detail on timing or supporting documents. The defendant may have denied key allegations without explaining the factual basis for those denials. Gaps like those often point you toward the right interrogatories.

This is also a good time to focus on facts tied to knowledge and circumstances. Who knew what, when did they know it, and what was happening around the events in dispute?

Questions like that can help you narrow the issues and pull out additional information that has not shown up in the pleadings or disclosures.

Here are a few facts to identify during this step:

• Dates
• People involved
• Communications
• Events
• Decisions made
• Damages claimed
• Injuries alleged
• Documents referenced
• Basis for denials
• Basis for affirmative defenses
• Witness knowledge
• Surrounding circumstances

3. Group Questions by Topic

A grouped set is easier to process and easier for the responding party to answer. Plus, it makes it easier to determine if a question is too broad, repetitive, or out of place.

Organizing by topic can also make reviewing simpler on your end. You and your client can scan each section, spot what is missing, and decide where more detailed questions may be needed.

Common topic groups include:

• Parties and background: Names, roles, relationships, and other basic facts tied to the dispute.
• Timeline of events: Dates, sequence, and timing of key events.
• Communications: Emails, calls, texts, letters, and related exchanges.
• Witnesses: People with relevant knowledge and the subjects they know about.
• Documents: Records mentioned in the pleadings or tied to disputed issues.
• Damages: Claimed losses, amounts, and supporting facts.
• Defenses: Facts supporting denials and affirmative defenses.
• Policies or procedures: Internal rules or usual practices connected to the claims.

4. Write Clear and Specific Questions

It goes without saying that clear interrogatories tend to get better answers. When a question is vague or crammed with too many ideas, the other side has more room to object or respond in a way that tells you very little.

To avoid that, make sure to:

• Keep the wording simple
• Stay focused on one point at a time
• Ask for facts that the other side can actually give

As you draft, keep the bigger picture in mind. A strong interrogatory can pin down facts, point you to useful evidence, and show what a party making a claim or defense may rely on to prove it later at trial.

At the same time, you want to avoid asking for privileged information, since that usually leads to an objection you could have seen coming.

For example, in a medical malpractice case, a weak interrogatory might say, “Explain everything that happened during the plaintiff’s treatment.”

As written, that leaves far too much open. A better version would say, “Identify each person involved in the plaintiff’s treatment on March 3, 2025, and describe the care each person provided.”

From there, the difference becomes pretty clear. The second version asks for specific people, ties the question to a clear date, and zeroes in on facts that may help your case.

5. Keep Each Interrogatory Focused

A focused interrogatory asks one question and aims at one issue. Narrow questions are usually easier for a court to view as reasonable. They show that you are trying to get targeted facts, not push the other side into writing a full case summary in one response.

They also work well alongside document requests. You can use an interrogatory to pin down a fact or position, then ask the other side to produce the records that support it.

For example, a broad interrogatory might say, “Identify all facts, witnesses, and documents supporting your denial of the allegations in the complaint.” That asks for too much all at once.

A tighter version would say, “Identify all facts supporting your denial of paragraph 12 of the complaint.”

The second version is easier to answer and easier to evaluate. It sticks to one issue, points to one part of the pleading, and gives you a clearer way to measure whether the response is complete.

6. Avoid Compound or Confusing Wording

If the question mixes too many ideas or leaves key terms undefined, the other side may answer only part of it or object on multiple grounds. That can slow things down and make it harder to get a clean response you can actually use in court.

With that in mind, keep the wording direct and easy to follow. Each interrogatory should ask for one thing in a way that does not force the other side to guess what you mean.

You also want to avoid phrasing that calls for a pure legal conclusion, especially when the facts are what you really need. Questions built that way often create room for objections from opposing counsel and may fail to give you anything useful.

Here are a few examples of wording problems:

• “State all facts, witnesses, and documents supporting each denial in your answer”
• “Explain everything you did and why you did it”
• “Identify all people involved and all communications related to the incident and damages”
• “Admit that your conduct violated the law”
• “State why your defense does not fail under the contract”
• “Describe every act or omission that supports your position”

7. Check for Relevance and Proportionality

Relevance means the question connects to the claims or defenses in a real way. Proportionality asks something slightly different: is the question appropriately sized for the case, or does it ask for far more than the dispute calls for?

Courts look at things like the burden of answering, the importance of the issue, and the actual value of the information you are trying to get.

A quick review here can be really helpful. Some questions may relate to the case in a loose sense but still push past the practical limitations of written discovery. Tightening those questions gives you a better shot at getting useful answers without inviting easy discovery objections.

That point comes up a lot in wrongful death cases. For example, asking the defendant to identify every employee who had any contact with the decedent over a ten-year period would likely be too broad for the nature of the dispute.

A narrower interrogatory might ask the defendant to identify each employee who communicated with the decedent during the week before the incident and state the subject of each communication.

That version is far more grounded. It stays tied to the events at issue and asks for information with a clearer connection to the case.

8. Revise for Clarity and Strategy

Once the draft is done, give it one more pass before service. Revision is where you clean up wording, catch overlaps, and make sure the set works as a whole.

Strategy also comes into sharper focus during this step. You want the interrogatories to move in a logical manner, build a clear record, and push the other side to commit to facts you may later use in motion practice or at trial.

A tighter set is usually more compelling than a long one filled with questions that all blur together. Additionally, you’ll be able to spot anything that may need revision before the other side gets formal notice of what you are asking.

Use this quick checklist before serving:

• Clear wording
• One issue per interrogatory
• No duplicate questions
• No vague terms
• Dates and names included where needed
• Tied to claims or defenses
• Relevant and proportional
• No request for privileged material
• Consistent with the pleadings
• Ordered in a logical flow
• Strong enough to support follow-up discovery
• Ready for service

Common Mistakes to Avoid When Writing Interrogatories

A few common mistakes can make your questions easier to object to and harder to use once the answers come in. Here are some examples:

• Making questions too broad: An interrogatory that sweeps too widely often gets a vague response or a boilerplate objection.
• Combining too many asks: Packing facts, witnesses, documents, and explanations into one question can make the answer incomplete or hard to pin down.
• Using vague wording: Terms without clear limits can leave too much room for interpretation.
• Repeating the same point: Slightly reworded duplicates waste space and weaken the set overall.
• Asking for a pure legal opinion: Interrogatories work better when they target facts and not abstract legal argument.
• Ignoring the role of form interrogatories: Standard questions can cover basic information efficiently, so there is no reason to reinvent them every time.
• Overusing special interrogatories: Custom questions are useful, but they should fill real gaps rather than repeat what standard forms already cover.
• Skipping a final review: Small wording problems can turn into bigger issues once the other side starts drafting objections to interrogatories.
