The term “contention interrogatory” is not a standard or recognized legal term. It appears to be a misinterpretation or a non-existent legal concept. In legal proceedings, interrogatories are a form of discovery in which one party asks written questions to another party. These questions are intended to elicit information that is relevant to the case.
While the term “contention interrogatory” does not exist, it’s possible that it is being used to refer to a specific type of interrogatory within a broader legal context. To understand what might be meant by “contention interrogatory,” we need to examine the function of interrogatories in litigation and how they are used to uncover a party’s claims and defenses.

Understanding the Purpose of Interrogatories
Interrogatories are a powerful discovery tool used by attorneys to gather information from opposing parties before trial. They are written questions that must be answered under oath. The primary goals of using interrogatories include:
- Identifying claims and defenses: Interrogatories can be used to force a party to state the specific legal theories they are relying on (their claims) and the reasons why they believe they should prevail (their defenses).
- Discovering factual support: Parties can ask questions to uncover the facts that support their opponent’s claims or defenses. This includes asking about witnesses, documents, and events.
- Pinpointing damages: Interrogatories can be used to detail the nature and extent of any damages a party claims to have suffered.
- Narrowing issues: By requiring specific answers, interrogatories can help to clarify the points of agreement and disagreement between parties, thereby narrowing the issues that need to be decided at trial.
- Preparing for depositions and trial: The answers to interrogatories can inform strategies for deposing witnesses and presenting evidence at trial.
Interrogatories are governed by rules of civil procedure, which vary by jurisdiction but generally allow for broad discovery of any non-privileged matter that is relevant to the subject matter of the action.
Types of Interrogatories
While there isn’t a category called “contention interrogatory,” interrogatories can be broadly categorized by their purpose and the type of information they seek. These often lead to the identification of a party’s “contentions.”
General Interrogatories
These are broad questions designed to elicit a general overview of a party’s position. They might ask for a summary of their claims, a list of all relevant documents, or the identity of all individuals with knowledge of relevant facts.
Specific Interrogatories
These are more targeted questions designed to delve into particular aspects of the case. For example, in a contract dispute, a specific interrogatory might ask for the exact date and time a breach occurred or the precise language in the contract that was allegedly violated.
Interrogatories Seeking Legal Conclusions
While parties are generally not required to provide legal conclusions or opinions in response to interrogatories, they are often asked to state the legal basis for their claims or defenses. This is where the concept of a party’s “contention” becomes most relevant.
The Concept of “Contentions” in Legal Discovery
In litigation, a “contention” refers to a party’s assertion or claim regarding a particular issue in the case. For instance, in a personal injury lawsuit, a plaintiff’s contention might be that the defendant’s negligence directly caused their injuries. A defendant’s contention might be that the plaintiff contributed to their own injuries through comparative negligence.
Attorneys frequently use interrogatories to force their opponents to articulate their contentions clearly and comprehensively. This is often done through what might be colloquially referred to as “contention interrogatories,” even if that is not their formal designation.
Formulating “Contention Interrogatories”
If one were to interpret “contention interrogatory” as a specific type of interrogatory designed to reveal a party’s contentions, then its formulation would focus on eliciting detailed explanations of claims and defenses.
Identifying the Core of a Party’s Case
The primary goal of drafting such interrogatories is to compel the opposing party to articulate the foundational elements of their legal position. This involves asking questions that require more than a simple “yes” or “no” answer.
Questions About Legal Theories
Attorneys might ask: “State all legal theories upon which you base your claim for [specific cause of action].” This forces the opposing party to identify the legal doctrines they intend to rely on.
Questions About Factual Basis
Following the identification of legal theories, the next step is to uncover the facts supporting them. This could involve questions like: “For each legal theory stated in response to Interrogatory No. [X], describe all facts that you contend support that theory.”
Questions About Damages and Relief

If damages are at issue, interrogatories would seek to detail the nature and calculation of those damages. For example: “Describe in detail each element of damages you claim, including the method of calculation and the supporting documentation.”
The Role of Specificity
The effectiveness of any interrogatory, including those aimed at uncovering contentions, lies in its specificity. Vague questions will likely yield vague answers.
Precision in Language
When drafting interrogatories to identify contentions, lawyers are careful with their wording. They will often define key terms and specify the scope of the information sought. For instance, instead of asking “What happened?”, an interrogatory might ask, “Describe all events that occurred on [date] between [time] and [time] at [location] that you contend constitute a breach of contract.”
Avoiding Ambiguity
The aim is to leave no room for misinterpretation. If a question can be answered in multiple ways, it is not an effective contention interrogatory. The question should be designed to elicit a single, definitive response concerning a specific assertion.
Strategic Use of Contention-Focused Interrogatories
The strategic deployment of interrogatories aimed at eliciting a party’s contentions is crucial for effective litigation. They serve to define the battleground and prevent surprises.
Uncovering Hidden or Undeveloped Claims
Sometimes, a party may have claims or defenses that are not fully developed or clearly articulated. Contention interrogatories can flush these out, forcing the party to commit to a particular position. This can be incredibly valuable for a responding party, as it helps to define the scope of discovery and trial preparation.
Early Identification of Weaknesses
By understanding the opponent’s contentions early on, a party can begin to identify potential weaknesses in their case and develop strategies to counter them. This might involve seeking out evidence that disproves a specific factual assertion or legal argument.
Setting the Stage for Further Discovery
Once contentions are clearly laid out, it becomes easier to target subsequent discovery efforts, such as depositions and requests for production of documents. Attorneys can then ask more precise questions and request more specific documents that are directly relevant to the established contentions.
Preventing “Sandbagging” and Trial by Ambush
“Sandbagging” refers to the practice of withholding information during discovery and then springing it on the opposing party at trial. Contention interrogatories help to prevent this by requiring parties to declare their positions upfront. If a party tries to introduce a new claim or defense at trial that was not previously disclosed through interrogatories, the opposing party can object, often successfully, arguing that they were ambushed.
Building a Foundation for Motions
Clearly defined contentions can also form the basis for pre-trial motions, such as motions for summary judgment. If a party’s stated contentions, even when accepted as true, do not legally support their claim or defense, the opposing party can file a motion arguing that there are no genuine issues of material fact and judgment should be entered in their favor.
Facilitating Settlement Negotiations
When both parties have a clear understanding of each other’s contentions, it can facilitate more productive settlement negotiations. Parties can assess the strengths and weaknesses of their respective cases and engage in discussions from a more informed position. This can lead to a more efficient and cost-effective resolution of disputes.
The Interplay with Other Discovery Tools
While interrogatories are valuable for eliciting initial contentions, they are often just one piece of the discovery puzzle.
Supplementation of Responses
In many jurisdictions, parties have a continuing duty to supplement their interrogatory responses as new information becomes available. This means that if a party’s contentions change or evolve during the course of litigation, they must update their prior answers.

Connecting to Depositions and Document Production
The answers provided to contention interrogatories will inform the questions asked during depositions and the types of documents requested in production. For example, if a contention interrogatory asks for the date of a specific event, a deposition question might then ask for a detailed account of what happened on that exact date. Similarly, if a contention is based on a particular document, that document will be a prime target for a request for production.
While the term “contention interrogatory” may not be a formal legal term, the concept it represents—interrogatories designed to elicit a party’s specific claims and defenses—is fundamental to the discovery process. By strategically utilizing interrogatories to uncover and define an opponent’s contentions, legal teams can gain a significant advantage in litigation, ensuring a clearer, fairer, and more efficient path toward resolution.
