A writ of summons is the court-issued document that formally tells you someone has sued you. Most American courts now call it simply a “summons,” though the older “writ of summons” label survives in a handful of states. It arrives with a complaint explaining what the plaintiff claims you did, and together the two documents start the clock on your response. In federal court, you generally have 21 days from the day you’re served to file something with the court. Miss that window and the plaintiff can ask for a default judgment against you.
Why the Document Matters
A summons does two things that make the lawsuit possible. It gives you legal notice that a case is pending, which satisfies due process. And once it’s properly served, it establishes the court’s personal jurisdiction over you, meaning the court now has authority to decide your rights and obligations in the case. If service wasn’t done right, the court lacks that authority and any judgment it enters can be challenged as void.
That is why the rules around service are strict, and why reading the paperwork carefully is the first thing to do.
What the Summons and Complaint Contain
The summons itself is short. Under the federal rules, it must identify the court and the parties, give the plaintiff’s attorney’s name and address (or the plaintiff’s own contact information if they’re representing themselves), state your deadline to respond, and warn that failing to respond will result in a default judgment.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons It will also carry a case or docket number the court uses to track the file.2United States Courts. AO 440 – Summons in a Civil Action
The complaint is where the real substance sits. It lays out the plaintiff’s version of events, the legal theories they’re relying on, and what they want from the court, whether money, an injunction, or something else. Read both documents closely. The complaint tells you exactly what you need to defend against.
How a Summons Gets to You
The formal delivery is called service of process, and it has to follow specific rules to be valid. The most common method is personal service, where someone physically hands you the papers. Under federal rules, a process server can also leave copies at your home with someone of suitable age and discretion who lives there, or deliver them to an agent you’ve authorized to accept service.1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Federal courts also permit service by whatever method the relevant state’s rules allow, which in many states includes certified mail.
If the Plaintiff Asks You to Waive Service
Before paying for formal service, a plaintiff can mail you a request to waive it. If you agree, you sign and return a waiver form, and your response deadline stretches from 21 days to 60 days (90 days if you’re outside the United States).1Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Waiving service does not give up your right to later challenge the court’s jurisdiction or venue. Refusing without good reason can backfire: the court can order you to pay the plaintiff’s costs of serving you formally, including attorney’s fees for the motion to recover those costs.
How to Respond
The summons will state your exact deadline. In federal court it’s 21 days after service.3Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections State courts set their own, often 20 or 30 days. Treat whichever number applies as a hard deadline. You generally have three options, and sometimes you’ll use more than one.
File an Answer
An answer walks through the complaint allegation by allegation. For each one, you admit it, deny it, or state that you don’t have enough information to respond. You can also raise affirmative defenses in the same document. These are reasons you should win even if the plaintiff’s facts are correct: the statute of limitations has run, the plaintiff’s own conduct contributed to the harm, the debt was already paid, fraud made the contract unenforceable, and so on.
File a Motion to Dismiss
Sometimes you can end the case early without answering the complaint on its merits. A motion to dismiss asks the court to throw the case out. The most commonly invoked grounds are lack of personal jurisdiction, improper venue, insufficient service of process, and failure to state a claim upon which relief can be granted.3Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections A motion to dismiss has to be filed before your answer. If it fails, you still get a chance to answer.
File a Counterclaim
If you have your own claims against the plaintiff, you can file a counterclaim with your answer. The federal rules draw a line that catches people out. A compulsory counterclaim arises from the same events the plaintiff is suing over, and you have to raise it now or lose it permanently.4Legal Information Institute. Federal Rules of Civil Procedure Rule 13 – Counterclaim and Crossclaim A permissive counterclaim involves a separate dispute and can wait for its own lawsuit. If you have any potential claim against the plaintiff connected to the same situation, raise it. Sitting on a compulsory counterclaim is one of the most expensive mistakes a defendant can make, because once judgment is entered that claim is gone.
If Service Was Done Wrong
If the plaintiff didn’t follow the rules in serving you, you can push back. A motion to dismiss for insufficient service of process is on the Rule 12 list, but it must be raised in your first responsive filing or it’s waived.3Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections Common defects include delivery by someone not authorized to serve, leaving papers with a minor or with an adult who doesn’t actually live in your home, and missing the deadline the plaintiff had to serve you.
Winning a service challenge usually just forces the plaintiff to serve you again correctly. But if the statute of limitations has run in the meantime, they may not be able to refile, which can end the case. Even if you learned about the lawsuit some other way, defective service is still grounds for dismissal.
What Happens If You Ignore It
Ignoring a summons is the worst move available. If you don’t respond by the deadline, the court can enter a default against you, which treats you as having given up the right to defend. The plaintiff then asks for a default judgment, and courts often grant it without hearing your side.5Legal Information Institute. Federal Rules of Civil Procedure Rule 55 – Default and Default Judgment
Once judgment is entered, the plaintiff becomes a judgment creditor with real collection tools. Depending on the state, these commonly include wage garnishment, levies on your bank accounts, and liens on real property you own. The plaintiff doesn’t need your cooperation to pursue any of them.
Setting Aside a Default Judgment
A default isn’t always permanent. Before a default judgment is entered, courts can set aside the entry of default for good cause, and the standard at that stage is relatively lenient.5Legal Information Institute. Federal Rules of Civil Procedure Rule 55 – Default and Default Judgment Once a default judgment is final, the bar is much higher. You’d need to file a motion under Rule 60(b) showing one of several specific grounds: mistake or excusable neglect, newly discovered evidence, fraud by the opposing party, that the judgment is void, that it has been satisfied, or that applying it going forward would be inequitable.6Legal Information Institute. Federal Rules of Civil Procedure Rule 60 – Relief from a Judgment or Order
For the first three grounds, you have one year from the judgment to file. There’s a catchall for “any other reason that justifies” relief, but courts reserve that for truly extraordinary situations. If you missed the deadline because you didn’t take the summons seriously, courts are unlikely to help. If you were hospitalized or never actually received the papers, you have a far stronger case. Either way, act quickly once you learn about the judgment, and plan on hiring an attorney to handle the motion.
