Subpoenas and deposition notices may seem similar, but they have different legal implications and procedural requirements. Whether you're compelling testimony from a third party or notifying an opposing party of an upcoming deposition, choosing the correct tool ensures procedural compliance and strategic advantage. This guide breaks down the key distinctions, practical uses, and common pitfalls of subpoenas and deposition notices.

Litigation relies heavily on effective discovery tools to gather evidence and secure testimony. Among the most frequently used tools are deposition notices and subpoenas. Although both involve requesting someone to appear and provide testimony under oath, their scope, application, and procedural rules differ significantly.

A deposition notice typically applies to parties already involved in the case, while a subpoena is used to compel non-party individuals or entities. Misunderstanding these distinctions can lead to avoidable delays, procedural missteps, or even sanctions.

❗ Using the wrong instrument can result in a failed discovery attempt.
✅ Mastering these tools enhances your ability to uncover crucial evidence and maintain litigation momentum.

🌟 Why This Guide Matters
Litigators and legal support teams must:
✅ Know when to use a deposition notice versus a subpoena
✅ Understand the procedural rules governing both tools
✅ Avoid common compliance issues that derail discovery
✅ Strategically apply each tool for maximum evidentiary impact

1. Deposition Notices: Internal Discovery for Parties

🔹 Purpose and Scope
A deposition notice is a formal written communication used within litigation to notify a party or a designated representative of a party that their oral testimony will be taken under oath outside of court. The primary purpose of a deposition notice is to schedule and outline the specifics of the deposition—essentially, to compel a party involved in the lawsuit, or someone acting on their behalf, to appear and provide sworn testimony. This is a key discovery tool because it allows the opposing party to question the deponent directly, clarify facts, and gather evidence that may be critical for trial preparation, settlement discussions, or motions practice.

Deposition notices are governed by Rule 30 of the Federal Rules of Civil Procedure (or comparable state or local procedural rules), which set the framework for how, when, and under what circumstances depositions may be taken. These notices help maintain transparency between opposing counsel and prevent surprise by clearly communicating essential information about the deposition.

In the case of corporate parties, deposition notices take on special significance under Rule 30(b)(6), which allows a party to designate one or more representatives to testify on specified topics on behalf of the organization, ensuring the corporation cannot evade discovery by sending an unprepared witness.

🔹 Requirements
To be valid and effective, deposition notices must contain specific information, including:
• Identification of the Deponent: The notice must clearly specify the name of the individual who is to be deposed. For corporate entities, this includes identifying the topics on which the company must prepare its designated representative(s) to testify, per Rule 30(b)(6). This ensures that the scope of testimony is defined and that the organization can prepare adequately.
• Date, Time, and Location: The notice must specify the exact date, start time, and physical location where the deposition will take place. This provides clarity and allows the deponent and their counsel to make necessary arrangements. Locations are often law offices, court reporting agencies, or other mutually agreed-upon venues.
• Method of Recording: The notice should indicate the manner in which the deposition will be recorded. Common methods include stenographic transcription, audio recording, or video recording. This ensures all parties are aware of how the testimony will be documented for later use in court or settlement negotiations.

🔹 Limitations
Deposition notices are designed to target parties or their representatives within the litigation and cannot be used to compel non-parties to testify or produce documents. Attempting to use a deposition notice to require a third party’s participation would be improper and unenforceable. Instead, subpoenas must be issued under Rule 45 to legally compel non-parties. This distinction protects individuals or entities not involved in the lawsuit from being burdened by discovery requests that are better suited for parties directly engaged in the case.

2. Subpoenas: Compelling Non-Parties

🔹 Purpose and Scope
Subpoenas serve as powerful legal instruments designed to compel the attendance of non-parties—individuals or entities not directly involved as plaintiffs or defendants in the litigation—to provide testimony or produce relevant documents. This can include former employees, independent contractors, vendors, consultants, or experts whose information is crucial to the case. Unlike deposition notices, which are generally directed at parties to the litigation, subpoenas extend the reach of discovery beyond the immediate parties to obtain evidence that might otherwise be inaccessible. Subpoenas ensure that key witnesses or custodians of records cannot evade participation simply because they are not formal parties to the lawsuit.

Subpoenas are governed by Rule 45 of the Federal Rules of Civil Procedure, which sets out the authority, issuance procedures, and enforcement mechanisms. Courts issue subpoenas to maintain judicial oversight and ensure compliance with due process, balancing the need for information with protection against undue burden.

🔹 Requirements
To be valid and enforceable, subpoenas must meet several stringent procedural requirements:
• Personal Service: Subpoenas must be served personally on the individual or entity commanded to appear or produce documents. Service by mail alone is typically insufficient unless authorized by court order or specific local rules. Personal service ensures the recipient is properly notified and reduces disputes over whether the subpoena was received.
• Clear Description: The subpoena must clearly describe the testimony sought or the documents requested. Vague or overly broad subpoenas risk being quashed or narrowed by the court. For example, a subpoena duces tecum (for documents) should specify categories or types of documents with enough detail to allow the recipient to identify responsive materials without undue guesswork.
• Jurisdictional and Territorial Limits: Subpoenas must comply with geographic and jurisdictional limits established by law. For instance, a subpoena issued by a federal court may only compel attendance within 100 miles of where the person resides, works, or regularly transacts business, or within the court’s district. Attempts to serve subpoenas outside these limits can be challenged and invalidated. Courts also scrutinize subpoenas to protect non-parties from excessive burden or harassment.

🔹 Types of Subpoenas
There are two primary types of subpoenas used in litigation, each serving a distinct discovery function:
• Subpoena ad testificandum: This subpoena commands an individual to appear and give oral testimony, usually at a deposition or trial. It requires the recipient to physically appear at a designated time and place to answer questions under oath.
• Subpoena duces tecum: This subpoena commands the production of documents, records, or tangible evidence. It may also require the person to appear for testimony in addition to producing materials. Often used to obtain emails, contracts, financial records, or electronic data relevant to the case.

3. Procedural and Practical Differences

🔧 Issuing Authority

• Deposition Notice: Filed by a party without needing court approval

• Subpoena: Requires court involvement and can be challenged in court more easily

🔧 Enforcement

• Deposition notices apply only to parties who are already obligated to participate in the case.

• Subpoenas can be enforced through contempt proceedings if the non-party fails to comply.

🔧 Objection and Motion Practice

• Parties may object to a deposition notice or file for a protective order.

• Non-parties may move to quash or modify subpoenas.

4. Common Mistakes to Avoid

❌ Using a Deposition Notice for a Non-Party
Attempting to compel testimony from someone not party to the case with only a deposition notice will fail—use a subpoena instead.

❌ Failing to Serve a Subpoena Properly
Subpoenas require personal service; mailing it without follow-up may render it unenforceable.

❌ Omitting Specific Topics in Rule 30(b)(6) Notices
Failing to clearly outline examination topics in corporate depositions can lead to inadequate witness preparation and objections.

❌ Ignoring Geographic Limitations on Subpoenas
Federal Rule 45 limits how far a subpoena can require a non-party to travel—usually 100 miles from where they live or work.

5. Strategic Tips for Choosing the Right Tool

📅 Plan Discovery Early
Map out your discovery strategy to identify when you’ll need non-party testimony versus party depositions.

💌 Coordinate with Counsel
Work with opposing counsel and non-party representatives to avoid disputes and facilitate smooth scheduling.

🌐 Account for Remote Testimony
Many courts permit remote depositions—ensure your notices or subpoenas reflect this, along with required platform and access details.

📃 Keep Documentation Organized
Whether serving a notice or subpoena, always retain proof of service and communicate with all involved parties to prevent procedural challenges.

FAQs: Subpoenas vs. Deposition Notices

Q1: Can I use a subpoena to compel a party to testify?
Not typically. Parties to a case are required to appear under standard discovery rules, so a deposition notice suffices. Use a subpoena only if the party is outside the court’s jurisdiction or has failed to appear.

Q2: Do I need court approval to issue a subpoena?
No, but it must be issued under the authority of the court where the case is pending. You may need a court clerk or attorney authorized to practice to sign it.

Q3: What happens if a non-party ignores a subpoena?
Failure to comply with a properly served subpoena can lead to contempt of court. You may file a motion to compel or request sanctions.

Q4: Are there special rules for subpoenaing documents from companies?
Yes. You must describe the documents with reasonable specificity and may need to coordinate with the company’s legal department to avoid burdensome requests or privileged data.

Q5: Can deposition notices be used in conjunction with subpoenas?
Yes. For example, if you want to depose a non-party and obtain documents from them, you can issue a subpoena that includes both a deposition and document production request.

Final Thoughts
Knowing when to use a deposition notice versus a subpoena is foundational to effective discovery. Each tool has unique rules, requirements, and strategic applications that, when used correctly, enhance your ability to obtain critical testimony and documents.
