Interrogatories Example and Common Types

What Are Interrogatories?

Interrogatories are written questions that the other side sends during the discovery process of a lawsuit. If you are the answering party, you have to respond in writing and do so carefully, since your answers can heavily influence how the case moves forward.

These written questions usually ask for facts tied to the dispute, such as:

• What happened
• Who was involved
• What injuries or losses are being claimed
• What facts support a claim or defense

In other words, they give the other party a way to learn your position before depositions or trial prep begin. They also give attorneys a chance to spot weak points, missing facts, or statements that may need follow-up later.

And since the answers become part of the case record, they need to be accurate, clear, and carefully worded.

What Does a Sample Interrogatory Look Like?

An interrogatory usually looks like a numbered written question followed by a space for the response. It is often included in a formal discovery document that one side will serve on the other.

For example, in a personal injury case, the plaintiff might send the defendant an interrogatory like this:

Interrogatory No. 3:

State all facts that support your contention that you were not negligent in the incident described in the complaint.

The response might look like this:

Response to Interrogatory No. 3:

Responding party states that the traffic signal was green at the time of entry into the intersection, that plaintiff entered against a red light, and that responding party exercised reasonable care at all relevant times. Investigation is ongoing, and responding party reserves the right to supplement this response.

This is the basic format. You get a numbered request, then a written answer or objection beneath it. Some responses also include objections before the answer.

Common Types of Interrogatories

Interrogatories can cover a lot of ground, but most of them fall into a few familiar categories. Here are five interrogatories common in the discovery process:

Background Interrogatories

Background interrogatories focus on basic information tied to the people, entities, and events in the case. They usually come early in discovery because the asking party wants a clearer picture of who is involved before moving into more detailed issues.

These questions often ask the opposing party to identify names, addresses, job titles, relationships, and other starting-point details. They can also ask about insurance, business roles, or the location of relevant resources and records.

Common examples include requests to identify:

• Full legal name
• Home or business address
• Date of birth
• Employer
• Job title
• Relationship to other parties
• Insurance coverage
• Business affiliations
• People with knowledge of the facts
• Locations of relevant documents

Fact-Based Interrogatories

Fact-based interrogatories focus on the facts behind a claim or defense. 

They ask you to spell out what happened, who was involved, and what information supports your position. These questions help the other side test your proof, narrow disputes, and see how well your allegations are defined.

You will see them in many case types, including car accident claims, contract disputes, and medical malpractice cases. A question may ask for the facts supporting a denial of liability. Another may ask a party to explain what happened before, during, and after the event in dispute.

In a medical malpractice case, for example, one interrogatory might ask what conduct allegedly caused the injury and what facts help prove that claim.

Common examples include:

• Facts supporting each claim
• Facts supporting each defense
• Date, time, and place of the incident
• Actions taken before or after the event
• Names of people involved
• Facts supporting denial of liability
• Facts supporting causation
• Facts supporting claimed damages

Damages Interrogatories

Damages interrogatories focus on what a party says they lost and what they want to recover. If the case includes a demand for compensation, these questions push that claim into specifics. They ask for:

1. Actual amounts
2. Supporting facts
3. The basis for each category of loss

These interrogatories may cover things like medical bills, missed work, property damage, future care, or emotional distress. They may also ask about insurance proceeds, reimbursements, settlements, or any other payment already made.

That gives the other side a clearer view of the damages claim and what documents or testimony may support it.

Typical requests include:

• Total amount of damages claimed
• Itemized medical expenses
• Lost wages
• Loss of earning capacity
• Property damage
• Repair costs
• Out-of-pocket expenses
• Future medical costs
• Emotional distress damages
• Date and amount of each payment received
• Insurance payments
• Documents supporting damages

Witness Interrogatories

Witness interrogatories are used to find out who may have information that could affect the case. Witnesses can include eyewitnesses, treating providers, company employees, investigators, or expert witnesses.

In some cases, the response may also need to identify people who gave statements or people with knowledge that could link a party to a key event, document, or defense.

These questions usually ask for names, contact details, and a short summary of what each person is believed to know. Once those details are disclosed, they can help the other side decide who they want to interview, depose, or otherwise obtain information from later.

If a response leaves out key witness details, the requesting party may try to compel a fuller answer.

You may also see questions aimed at who is responsible for keeping witness statements, recordings, or related records. Questions like these can become important before a hearing, during motion practice, or while preparing for trial.

Document-Related Interrogatories

Document-related interrogatories deal with the paper trail behind the case. Essentially, they are used to pin down what records exist, what they relate to, who has them, and how they support a claim or defense.

If documents are central to the dispute, this section of discovery can tell you a lot about what each side plans to rely on.

These interrogatories can be especially useful after an initial exchange of records leaves gaps or raises follow-up questions. For instance, a lawyer may use special interrogatories to ask for narrower details, or send a later set after production turns up new information.

Plus, document-related interrogatories can help narrow disputes over missing records, vague references, or claims that collection would create too much burden.

Some document-related interrogatories ask for details like these:

• Identify all documents that support your claims: State what records back up the factual or legal positions being asserted.
• Identify all communications about the incident: Cover emails, letters, text messages, memos, or other written exchanges.
• State who has custody of relevant documents: Clarify who holds the records and where they are kept.
• Identify documents tied to damages: Point to bills, invoices, estimates, receipts, or payment records.
• Describe any documents withheld: Show what was not produced and why.

How to Write Strong Interrogatory Responses

At the very least, a strong interrogatory response needs to be clear, accurate, and focused. These four steps can help you get there:

1. Read Each Question Carefully

Read the interrogatory slowly and break it into parts before you answer. Look for dates, names, time periods, definitions, and any wording that may limit or expand what one party is asking.

Another important step is to compare the question to the complaint, answer, and any other discovery already filed in the case. Doing so can help you catch wording that seems harmless at first but could box you into an incomplete or inconsistent response.

As you review it, make a note of anything vague, too broad, or built on an assumption that may need a discovery objection or a qualified answer.

2. Answer Only What the Question Asks

Keep your answer tied to the exact question and no more. If a request asks for a date, give the date. If it asks for facts supporting one allegation, respond to that allegation rather than giving a full case narrative.

Being concise helps keep the response complete without giving away additional information that the other side did not ask for.

This practice also helps when a question feels overly broad. In a limited civil case, for example, a party may still send a request that reaches farther than it should. A careful answer stays within the actual wording of the interrogatory and avoids filling gaps that the other side left open.

For instance, if the interrogatory asks you to identify the date of the incident, a focused response would state the date of the incident. It would not also volunteer a full description of the event, list witnesses, and summarize medical treatment unless the question asked for that too.

3. Check the Facts Before You Respond

Before you serve anything, make sure the facts line up with the records, the pleadings, and your client’s position.

Interrogatory answers are usually given under oath, so accuracy matters from the very start. A rushed answer can create problems later if it conflicts with documents, deposition testimony, or another response.

You also need to check the applicable rules before finalizing anything. Some objections are permitted, some answers need verification, and some responses may need to mention an agreement to produce more information later. You usually cannot simply refuse to answer without a valid basis.

Remember: If you are drafting interrogatory responses, take time to confirm names, dates, timelines, and supporting facts before anything goes out. That extra review can save you from corrections, disputes, or credibility issues later.

4. Use Objections Carefully and Clearly

Objections can protect your client, but they need to be specific and grounded.

A vague objection often creates more trouble than it solves. If a question is unclear, overly broad, seeks privileged material, or goes beyond what is allowed, say so plainly and explain the issue in a way that fits the request.

It also helps to know what type of discovery you are dealing with. Form interrogatories tend to follow standard language, while a custom or final set may raise narrower disputes.

Sometimes, you may also need to look at local rules on how many questions can be served or how discovery differs from requests for admissions.

After service, a weak objection can invite a meet-and-confer letter or a motion to compel. In contrast, a careful one gives notice of the problem while preserving your position.

This discovery objection cheat sheet can be a valuable resource when preparing these responses.
