According to the Administrative Office of the U.S. Courts, the American legal system relies on formal written orders to compel participation in legal proceedings, including subpoenas and summonses. These documents carry legal authority and ignoring them can lead to serious consequences.
A subpoena and a summons are both court-issued or court-authorized documents, yet each one demands a different type of response. Confusion between the two causes missed court dates, default judgments, and contempt charges for thousands of Americans every year.
What Is a Summons Under U.S. Law?
A summons is a legal document that formally notifies an individual, business, or government entity that a lawsuit has been filed against them.
Legal definition
Under Federal Rule of Civil Procedure 4, a summons is issued by a court clerk and served to a defendant along with a copy of the complaint.
Purpose of a summons
The summons exists to achieve one clear goal: Inform the defendant and require a formal response within a specific timeframe.
Who receives a summons?
A summons is sent to:
- Individuals
- Corporations
- Small businesses
- Government agencies
Required response timeline
In federal civil cases:
- 21 days to respond after service
- 60 days if the defendant is the U.S. government
State courts often require 20 to 30 days, depending on state law.
What happens after receiving a summons?
The defendant must:
- File an answer
- File a motion to dismiss
- File another legally valid response
Failure to respond triggers legal consequences.
Example of a summons
A landlord files a lawsuit for unpaid rent totaling $8,400. The court issues a summons ordering the tenant to respond within 30 days. The tenant ignores it. The judge enters a default judgment, allowing wage garnishment of 25% of disposable income, as permitted by federal law.
