Subpoena vs Summons: Key Differences
Short answer
A subpoena is a legal order requiring a person to testify or provide evidence in a court case, while a summons is a document that notifies a defendant they are being sued and must respond or appear in court. Subpoenas compel participation in gathering evidence, whereas summonses initiate a lawsuit by informing defendants of claims against them.
What Is a Subpoena?
A subpoena is an official court document that commands an individual or organization to either appear and testify as a witness or produce documents and evidence relevant to a legal case. The two common types are the subpoena ad testificandum, which requires a person’s presence to give testimony, and the subpoena duces tecum, which requires producing physical evidence or documents.
For example, in a civil dispute over a contract, a party might receive a subpoena duces tecum asking for copies of emails or contracts related to the issue. A witness might receive a subpoena ad testificandum to appear in court and testify about what they observed. The subpoena typically states the time, place, and nature of the requested testimony or evidence.
Upon receiving a subpoena, take these steps:
- Read the entire document carefully to understand exactly what is required.
- Note the deadline or court date for compliance.
- Gather the requested documents or prepare testimony as outlined.
- Contact a lawyer or legal aid service to review the subpoena if there are questions or concerns.
- Follow the instructions precisely; failing to comply can result in court sanctions, such as fines or contempt charges.
For instance, if a subpoena demands medical records related to a case, it may require working with your health provider to release those records legally. If the scope of the subpoena feels too broad or intrusive, it is possible to file a motion to quash or modify it, but this requires prompt legal action.
What Is a Summons?
A summons is a formal notice from the court informing an individual or entity that they are being sued and must respond to the complaint filed against them. It initiates the lawsuit and outlines how and when the defendant must take action to avoid default. The summons usually accompanies the complaint, which details the claims or allegations.
For example, if a landlord sues a tenant for unpaid rent, the tenant will receive a summons along with the complaint. The summons will specify the court’s name, the parties involved, and the deadline for the defendant to file an answer or appear at a hearing. It will also explain the consequences of ignoring the summons, typically resulting in a default judgment against the defendant.
Steps to take when served with a summons:
- Carefully read the summons and accompanying complaint to understand the claims.
- Note the deadline for responding, which is often 20 or 30 days but varies by jurisdiction.
- Decide whether to hire a lawyer or file a response independently.
- Prepare and file an answer or motion with the court by the deadline.
- Keep copies of all documents and proof of filing or service.
For example, a sample response might begin with: “Defendant hereby answers the complaint as follows…” and then respond point-by-point to the allegations, asserting defenses or denials. Responding timely is critical to protect legal rights and avoid losing the case automatically.
How Do Subpoenas and Summonses Differ?
| Feature | Subpoena | Summons |
|---|---|---|
| Purpose | Compel testimony or production of evidence | Notify defendant of a lawsuit and require response |
| Initiates lawsuit? | No | Yes |
| Issued by | Court or attorney | Court |
| Recipient | Witness, party, or third party | Defendant |
| Required response | Appear in court or produce documents | File an answer or appear in court |
| Consequences if ignored | Contempt of court, fines, possible jail | Default judgment against defendant |
| Typical use cases | Evidence gathering, trial preparation | Starting civil lawsuits, eviction cases, debt collection |
This table illustrates that the subpoena focuses on gathering information to support a case, while the summons starts the legal dispute and requires the defendant to respond. Both are legally binding but serve different roles in the court process.
Who Typically Receives a Subpoena or a Summons?
A subpoena can be served on anyone who has relevant information or evidence, including parties to the lawsuit, witnesses, or third parties such as businesses or organizations. For example, a bank might receive a subpoena to provide account statements related to a fraud investigation. A witness who observed an accident may receive a subpoena ad testificandum to testify in court.
Conversely, a summons is served only on the defendant—the person or entity being sued. For example:
- A customer sued for unpaid credit card debt receives a summons.
- A tenant sued for eviction receives a summons.
- A company sued for breach of contract is served a summons.
Knowing who is the recipient clarifies the role: subpoenas are about evidence or testimony, summonses are about appearing to defend against claims.
How Does a Subpoena Differ From a Court Order?
A court order is a broad term for any directive issued by a judge that requires a person to do or refrain from doing something, such as a restraining order, injunction, or eviction order. It covers a wide range of actions depending on the case.
A subpoena is a specific type of court order focused on compelling attendance or production of evidence relevant to a legal proceeding. For example, a judge might issue a court order to evict a tenant, but a subpoena might be issued to compel a witness to testify about rent payments.
Both carry legal authority, but subpoenas are narrowly focused on evidence gathering and testimony, while court orders can cover many other judicial commands.
How Is a Subpoena Different From Discovery?
Discovery is the pre-trial phase during which parties exchange information to prepare their cases. It includes interrogatories (written questions), requests for admission, depositions (sworn testimony), and requests for production of documents.
A subpoena is one tool used in discovery, especially to obtain information from non-parties or reluctant parties. For example, a party may issue a subpoena duces tecum to a third-party company to produce relevant emails during discovery.
Discovery often involves cooperation between parties, but subpoenas legally compel evidence or testimony from those who might otherwise not participate willingly.
What Questions Should Be Asked When Receiving a Subpoena or Summons?
When receiving a subpoena or summons, asking these questions can guide appropriate action:
- Who issued this document? Verify if it is from a legitimate court or authorized attorney.
- What exactly am I required to do? Testify, produce documents, file a response, or appear in court.
- What is the deadline for compliance or response? Mark deadlines clearly.
- Is the request reasonable and relevant? Determine if the subpoena’s scope is too broad or unrelated.
- Can objections be made? Investigate whether it is possible to challenge or modify the subpoena.
- What are the consequences of ignoring it? Understand risks such as fines, contempt charges, or default judgments.
- Should legal advice be sought? Consider consulting a lawyer or legal aid service to protect rights.
For example, if a subpoena demands personal financial records unrelated to the case, it may be appropriate to file a motion to quash or narrow the request. Acting promptly helps avoid penalties and ensures rights are preserved.
Can a Subpoena Be Converted Into a Summons or Vice Versa?
It is not possible to switch a subpoena into a summons or a summons into a subpoena because they serve different legal functions.
- A subpoena compels evidence or testimony for a case already in progress.
- A summons notifies a defendant of a lawsuit and requires a response to avoid default.
However, these documents can intersect in litigation. For example, a defendant served with a summons may later issue subpoenas to collect evidence. A witness subpoenaed may become a party and receive a summons. Understanding these distinctions clarifies legal roles and obligations.
