Interrogatories are a powerful discovery tool in civil litigation—if drafted correctly. This guide breaks down how to write effective interrogatories that extract useful information and avoid objections.

In civil litigation, information is power. And few tools are as foundational—or as underutilized—as interrogatories. These are written questions one party serves on the other to obtain factual details, admissions, and clarifications during the discovery process. While the concept is simple, the execution matters. Poorly drafted interrogatories invite objections, confusion, or vague responses. Well-crafted ones, on the other hand, shape your narrative, reveal weaknesses, and pin down key facts.

In this step-by-step guide, Legal Husk walks you through how to draft interrogatories that are strategic, compliant, and effective—plus tips to ensure they hold up in court.

1. Understand the Purpose of Interrogatories

Before drafting even a single question, it’s critical to step back and ask: What am I trying to achieve through interrogatories in this case?

Unlike other discovery tools like depositions or requests for production, interrogatories are uniquely positioned to extract precise information in a controlled, written format. They’re not about surprises—they’re about laying a clear factual foundation and setting the tone for future discovery.

🎯 Interrogatories Are Best Used To:

• Identify Key Actors

Uncover the names, roles, and contact information of individuals involved in or with knowledge of the events in question. This may include:

• Eye witnesses

• Employees who handled a specific transaction

• Third parties who were involved but not named in the suit

📌 Purpose: Knowing who the players are allows you to plan depositions, subpoenas, or further interrogatories that dig deeper.

• Clarify Timelines and Events

Interrogatories can map out the sequence of events, especially in cases involving disputes over dates, actions, or transactions. A well-phrased interrogatory can force the other side to commit to a version of the timeline early in the litigation.

📌 Purpose: Timelines established through interrogatories become critical when cross-referencing documents, emails, and depositions.

• Define Terms or Positions

Legal disputes often hinge on how terms or actions are interpreted. Interrogatories can ask parties to explain or define:

• What a contract clause meant to them

• The basis of a particular defense

• How they categorize certain actions or obligations

📌 Purpose: This helps you expose inconsistencies or prepare to challenge the opposing party’s interpretation later in the case.

• Uncover Supporting or Damaging Facts

Use interrogatories to require the opposing party to disclose:

• The factual basis of each affirmative defense

• Any known evidence supporting a claim or counterclaim

• Admissions of responsibility or denial of allegations

📌 Purpose: This lets you assess the strength of their case and guides how you build your rebuttal or trial strategy.

• Narrow the Scope of Future Depositions or Document Requests

Strategic use of interrogatories can help you avoid unnecessary fishing expeditions by refining what you ask for in future discovery.

📌 Purpose: By understanding the “who, what, and when,” you can draft more focused RFPs and ask targeted deposition questions—saving time and budget.

📌 Expanded Example:

Case: Contract Dispute between a vendor and supplier
Objective: Establish when and how the contract was formed, and who approved the terms.

Sample Interrogatories:

INTERROGATORY NO. 1: Identify the individual(s) who negotiated and executed the contract on behalf of the Defendant, including their roles and titles.

INTERROGATORY NO. 2: State the date on which the Defendant signed the contract attached as Exhibit A.

INTERROGATORY NO. 3: Describe all communications regarding the delivery timelines set forth in Section 4 of the contract.

2. Know the Legal Framework

Each jurisdiction limits:

• The number of interrogatories (e.g., Rule 33 of the Federal Rules of Civil Procedure caps them at 25 unless leave is granted)

• Deadlines for service and response (typically 30 days)

• Objection protocols (responses must state objections with specificity)

🎯 Tip: Always check your local rules and standing orders. Courts differ on whether subparts count toward the limit.

3. Tailor Interrogatories to Case Themes

Don’t just fire off boilerplate questions. Instead, align each interrogatory with a strategic goal in your case.

Ask yourself:

• What elements do I need to prove or disprove?

• What defenses has the opposing party raised?

• What factual gaps do I need to fill before depositions?

📌 Example: If the opposing party alleges fraud, interrogatories should focus on intent, representations made, and knowledge of falsity.

4. Use Clear, Concise, and Neutral Language

When drafting interrogatories, clarity is your most powerful weapon. The goal is to obtain usable, admissible facts—not to provoke the other side into a volley of objections or vague answers. Poorly worded questions waste time, erode your credibility, and undermine the effectiveness of your discovery strategy.

To ensure your interrogatories serve their purpose and stand up to scrutiny, follow these best practices:

✏️ Use Plain, Direct Language

Avoid legalese and overly technical jargon unless it’s essential and defined. Write in a way that any reasonable reader—even someone outside the legal field—can understand.

📌 Instead of: “Enumerate all contractual obligations assumed by the Defendant as stipulated in the governing instruments.”
📌 Use: “Identify all obligations the Defendant agreed to under the written contract dated March 5, 2023.”

Clear writing forces precise answers and reduces ambiguity.

⚠️ Avoid Compound or Confusing Questions

Every interrogatory should ask one question only. Compound questions—those that ask for multiple pieces of information in a single prompt—are ripe for objection and can confuse the respondent.

📌 Weak: “Describe your role in the incident, whether you were aware of any risks, and who else was present.”
📌 Strong:

• “Describe your role in the events of July 10, 2022.”

• “State whether you were aware of any hazardous conditions prior to the incident.”

• “Identify all persons who were present at the time of the incident.”

Breaking complex queries into separate, targeted questions ensures clarity and allows you to hold the responding party accountable for incomplete answers.

🎯 Be Fact-Focused, Not Argumentative

Interrogatories are not an opportunity to litigate or editorialize. Avoid framing questions in ways that suggest guilt, blame, or legal conclusions—that’s a fast track to objections or nonresponsive answers.

📌 Avoid: “Explain why you failed to supervise your employees properly on the date in question.”
📌 Use: “State whether you were present at the workplace on October 2, 2023, and describe your responsibilities during that time.”

Neutral tone is key—your questions should be framed to uncover facts, not to provoke defensiveness.

✅ Ask One Question Per Interrogatory

This isn’t just a formatting tip—it’s often a jurisdictional requirement. In federal court (and many state systems), parties are limited in how many interrogatories they can serve. A single interrogatory that actually contains two or more questions (e.g., subparts) may count against that limit.

Even outside of limits, one-question-per-interrogatory improves clarity and allows:

• Easier tracking of compliance

• Cleaner responses for use in motions or trial

• Simpler objections and follow-ups if necessary

📌 Example Breakdown

❌ Poorly Drafted Interrogatory:

“Please explain all your actions related to the incident, including any knowledge you may or may not have had, who you told, and when it happened.”

• Problems: It's vague, compound, calls for a narrative, and is objection-prone.

✅ Well-Drafted Interrogatory:

“Identify all persons you communicated with regarding the events of June 14, 2023.”

• Why it works: It's focused, specific, and neutral—making it difficult to object to and easy to answer.

🔍Review Each Question for Clarity

Before finalizing your interrogatories, read each question as if you're opposing counsel. Would you object for vagueness, overbreadth, or ambiguity? If the answer is yes, revise the language.

You want responses that are clear, direct, and admissible—not cluttered with qualifiers, objections, or confusion.

5. Avoid Common Objection Triggers

Avoid phrasing that invites objections for:

• Vagueness or ambiguity

• Relevance (especially if the question is overly broad)

• Burden (questions requiring exhaustive narrative answers)

🎯 Tip: Review recent interrogatories served by experienced counsel in similar cases—they’ll show you how to keep things tight and relevant.

6. Include Definitions and Instructions (When Necessary)

If your questions rely on technical terms or assume certain timeframes, define those terms upfront.

📌 Example Definitions Section:
“As used herein, ‘Contract’ refers to the written agreement signed between Plaintiff and Defendant on or around May 5, 2021.”

Also, include brief instructions like:

• “Each response must be answered fully, separately, and under oath.”

• “If you object, state all grounds for the objection and answer to the extent the question is not objectionable.”

7. Number and Structure Your Questions Properly

Good structure ensures clarity and compliance.

Structure Example:

INTERROGATORY NO. 1:
Identify all individuals who were present at the warehouse on January 12, 2023, during the time of the alleged incident described in Paragraph 4 of the Complaint.

This formatting helps keep discovery exchanges organized and court-friendly.

8. Review and Revise Before Serving

Before finalizing your interrogatories:

• Cross-check against your discovery goals

• Remove duplicates or unnecessary questions

• Eliminate any ambiguity

• Verify that the number of questions complies with limits

🎯 Tip: Have a colleague do a quick read-through from the lens of the opposing party. If they can see objections coming, revise accordingly.

9. Sample Interrogatory Set (Basic Civil Case)

Here’s a sample of a short interrogatory set in a negligence case:

INTERROGATORY NO. 1:
Identify all persons who were present at the location of the incident on March 9, 2023.

INTERROGATORY NO. 2:
State whether you were aware of any hazardous conditions on the premises prior to the incident.

INTERROGATORY NO. 3:
Describe all steps taken by you or your agents to inspect or remedy hazardous conditions in the 30 days prior to the incident.

INTERROGATORY NO. 4:
Identify any photographs, video recordings, or written reports related to the incident.

INTERROGATORY NO. 5:
State whether you admit or deny the allegation that the condition causing the injury existed for more than 48 hours prior to the incident.

10. Final Thoughts: Interrogatories as a Strategic Weapon

Interrogatories aren’t about fishing—they’re about precision targeting. When drafted carefully, they set the tone for the rest of discovery, define what depositions will explore, and put pressure on opposing counsel to clarify their case. They are also cost-effective compared to depositions and help preserve testimony early.

With the right mix of strategy, clarity, and compliance, your interrogatories can pin down facts, test credibility, and build leverage—long before trial.
