An answer to a complaint is your written response to a lawsuit filed against you, and in federal court it is due within 21 days of being served with the summons and complaint. The document responds to each numbered allegation one by one, raises any legal defenses you want to preserve, and asserts any claims you have against the plaintiff arising from the same events. Anything you fail to address is treated as admitted, so the draft has to be complete before it goes out the door.
How Long You Have to Respond
The summons states your deadline. Under the Federal Rules of Civil Procedure, you generally have 21 days after being served with the summons and complaint to file your answer.1Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections: When and How Presented State courts set their own windows, commonly 20 to 30 days depending on the jurisdiction and the method of service.
If you signed a waiver of service under Rule 4(d) instead of being formally served by a process server, the deadline stretches to 60 days from the date the waiver request was sent, or 90 days if you were outside the United States.1Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections: When and How Presented Read the summons carefully to confirm which deadline applies.
Asking for More Time
If you cannot meet the deadline, the simpler path is contacting the plaintiff’s attorney and asking for a written stipulation extending your time. Most attorneys will agree to a reasonable first extension. The stipulation should identify the parties, state the new deadline, and give a reason. Some judges require any stipulated extension to be filed with the court before it takes effect, so check the local rules.
If the plaintiff refuses, you can file a motion under Rule 6(b) asking the court to extend the deadline for good cause, provided you file before the original deadline expires.2Office of the Law Revision Counsel. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time After the deadline has passed, the court can still grant an extension, but only if you show the delay resulted from excusable neglect. That is a harder argument to win, so moving before time runs out is always the better option.
What Happens If You Miss the Deadline
Missing the deadline can end the case before you present your side. The plaintiff can ask the court clerk to enter a “default” against you, and the clerk is required to do so once the plaintiff shows you failed to respond.3Legal Information Institute. Federal Rules of Civil Procedure Rule 55 – Default and Default Judgment The plaintiff can then seek a default judgment for the full amount claimed in the complaint, including interest and attorney fees.
A default is not always permanent. The court can set aside an entry of default for “good cause,” and it can vacate a final default judgment under the more demanding standards of Rule 60(b).3Legal Information Institute. Federal Rules of Civil Procedure Rule 55 – Default and Default Judgment Courts weigh how quickly you acted, whether you have a viable defense, and whether the plaintiff would be harmed by reopening the case. Undoing a default is still an uphill fight. Treat the deadline as immovable.
Filing a Motion to Dismiss Instead
Before answering, you can challenge the lawsuit itself with a motion to dismiss under Rule 12(b). Grounds include:1Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections: When and How Presented
- Lack of subject-matter jurisdiction, meaning the court has no authority over this type of case.
- Lack of personal jurisdiction over you specifically.
- Improper venue.
- Insufficient process or service of process.
- Failure to state a claim, meaning that even if every allegation is true, the complaint does not describe a legally recognized wrong.
- Failure to join a required party.
Filing a Rule 12(b) motion pauses your obligation to answer. If the court denies the motion, you then have 14 days from receiving notice of the ruling to serve your answer.1Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections: When and How Presented A denied motion does not end the case; you still get to answer and defend on the merits.
Format and Caption
The answer follows the same general format as the complaint. At the top of the first page, the caption identifies the court, the parties, and the case number assigned by the clerk.4Legal Information Institute. Federal Rules of Civil Procedure Rule 10 – Form of Pleadings Copy this information exactly from the complaint. Title the document “Answer to Complaint” or whatever designation your court requires.
The body uses numbered paragraphs that correspond to the numbered allegations in the complaint.4Legal Information Institute. Federal Rules of Civil Procedure Rule 10 – Form of Pleadings If the complaint has 35 numbered paragraphs, your answer has at least 35 numbered responses. Sections for affirmative defenses and counterclaims follow. Many courts publish templates that handle the caption, numbering, and signature block, leaving you to fill in the responses.
How to Respond to Each Allegation
For each numbered paragraph, you pick one of three responses. Choosing the right one for each allegation is where most of the real work happens.
Admit
Admitting an allegation means you agree it is true. Use this for facts you cannot reasonably dispute, like your name, your address, or the existence of a contract you signed. Every admission removes that fact from dispute and relieves the plaintiff of proving it at trial. Be precise. Do not admit an entire paragraph when only part of it is accurate.
Deny
A denial forces the plaintiff to prove the allegation. You can deny an entire paragraph or deny it in part. When a paragraph mixes true and false statements, admit the true portion and deny the rest.5Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading If a paragraph says “Defendant signed the contract on March 1 and breached it on April 15,” and you signed but dispute the breach, admit signing and deny breaching.
If you genuinely dispute every allegation, including the jurisdictional statements, you can file a general denial rather than responding paragraph by paragraph.5Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading General denials are rare in practice because most complaints contain at least some facts the defendant cannot honestly contest.
Lack of Sufficient Knowledge
When you honestly do not know whether an allegation is true, you can state that you lack sufficient knowledge or information to form a belief about its truth. This response functions as a denial.5Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading It fits allegations about the plaintiff’s own internal records, medical conditions, or other matters you cannot independently verify. Do not use it for facts you clearly know. A court will not accept a defendant claiming ignorance about whether they signed their own contract.
The Cost of Skipping a Paragraph
Any allegation you fail to address, other than a claim about the amount of damages, is treated as admitted.5Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading If the complaint has 40 paragraphs and you respond to only 38, the judge treats the missing two as undisputed facts. Reviewing every paragraph before filing is not optional.
Affirmative Defenses
An affirmative defense is different from a denial. A denial says the alleged event did not happen. An affirmative defense says that even if it did happen, there is a legal reason you are not liable. You carry the burden of proving any affirmative defense you raise, and failing to include one in your answer can waive it entirely.
Rule 8(c) requires you to state any defense that would avoid liability even if the plaintiff’s allegations are true. Common examples include:5Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading
- Statute of limitations, meaning the plaintiff waited too long to sue.
- Payment, meaning the debt or obligation was already satisfied.
- Release, meaning the plaintiff signed a settlement or waiver.
- Fraud or duress in the underlying agreement.
- Contributory negligence, meaning the plaintiff’s own conduct contributed to the injury.
- Estoppel, meaning the plaintiff’s prior conduct prevents the current claim.
- Res judicata, meaning the same claim was already decided in a prior lawsuit.
The list is not exhaustive. Any legal theory that would excuse liability regardless of the truth of the plaintiff’s facts belongs in the answer. Courts are far more forgiving of an unnecessary defense than a missing one.
Counterclaims
The answer is also where you assert claims of your own against the plaintiff, and the distinction between two types has teeth.
A compulsory counterclaim is any claim you have against the plaintiff that arises from the same transaction or events described in the complaint.6Legal Information Institute. Federal Rules of Civil Procedure Rule 13 – Counterclaim and Crossclaim If you do not raise it now, you lose it. The claim is permanently barred. If the plaintiff sues you for breach of a contract and you believe the plaintiff breached first, that counterclaim goes in the answer.
A permissive counterclaim is any claim you have against the plaintiff that does not arise from the same events. You can include it for the efficiency of resolving both disputes together, but you are not required to. A counterclaim can seek any type of relief and is not limited to the amount the plaintiff requested.6Legal Information Institute. Federal Rules of Civil Procedure Rule 13 – Counterclaim and Crossclaim
Signing the Answer
Every answer ends with a signature block listing the signer’s name, address, and telephone number. The signature carries legal weight. Under Rule 11, by signing you certify that your factual statements have evidentiary support, that your denials are warranted by the evidence or a reasonable lack of information, and that the document is not filed for an improper purpose such as harassment or delay.7Legal Information Institute. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers
Courts can impose sanctions for Rule 11 violations, including orders to pay the other side’s attorney fees. There is a built-in safety valve. The opposing party must serve a sanctions motion on you first, and you have 21 days to withdraw or correct the offending statement before the motion can be filed with the court.7Legal Information Institute. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers Some jurisdictions also require a verification page where the defendant signs under penalty of perjury that the statements are true to the best of their knowledge.
Filing and Serving
Once drafted, the answer must be delivered to the court and to the opposing side. Most courts now use electronic filing systems that produce a time-stamped confirmation. Where electronic filing is not available, you can deliver the answer in person to the clerk’s office or send it by certified mail with return receipt.
You must also serve a copy on the opposing side. If the plaintiff has an attorney, serve the attorney rather than the plaintiff directly. Electronic filing through the court’s system generally makes a separate certificate of service unnecessary. For any other method, file a certificate of service that states the date, method, and recipient.8Legal Information Institute. Federal Rules of Civil Procedure Rule 5 – Serving and Filing Pleadings and Other Papers Filing fees vary by jurisdiction; some courts charge nothing, others charge several hundred dollars.
Fixing Mistakes After Filing
Mistakes in an answer are fixable, especially early. Under Rule 15, you can amend your answer once as a matter of course, without needing the court’s permission, as long as you do so within 21 days after serving it.9Legal Information Institute. Federal Rules of Civil Procedure Rule 15 – Amended and Supplemental Pleadings If the plaintiff files a motion or responsive pleading challenging your answer, the 21-day clock starts from the date that motion or pleading was served, whichever comes first.
After that window closes, you need either the opposing party’s written consent or the court’s permission. Courts generally grant leave to amend freely when the case is still in its early stages, the amendment will not cause unfair delay, and the opposing side will not be prejudiced. The ability to amend matters most when you realize you left out an affirmative defense or a compulsory counterclaim. Catching the mistake inside the 21-day window avoids having to argue for the court’s discretion later.
