How to Respond to a Lawsuit: Step-by-Step Guide (2026)

Step 1: Understand What You've Been Served

When a lawsuit is filed against you, you'll receive a summons and complaint. These are two separate documents:

• The summons is the official notice from the court telling you that a lawsuit has been filed and that you have a specific number of days to respond. It will typically state the deadline prominently.
• The complaint is the plaintiff's statement of what happened, what they're claiming you did wrong, and what they're asking for (damages, injunctions, etc.).

Read both documents carefully. Note the court where the case was filed, the case number, and — most importantly — the response deadline. The typical deadline to file a response in federal court is 21 days. In most state courts, it ranges from 20 to 30 days. Some courts allow more time for complex cases or out-of-state defendants.

Step 2: Do Not Ignore It or Delay

This bears repeating: ignoring a lawsuit is never a viable strategy. If you fail to respond by the deadline:

• The plaintiff can file for a default judgment
• The court can enter judgment in the plaintiff's favor for the full amount requested
• With a judgment, the plaintiff can garnish your wages, levy your bank accounts, or place liens on your property

Setting aside a default judgment is possible but requires showing the court you had a valid reason for missing the deadline — and even then, it's not guaranteed. Don't put yourself in that position.

Step 3: Consult an Attorney Immediately

For most civil lawsuits, consulting with a defense attorney as soon as possible after being served is strongly advisable. Here's why:

• An attorney can quickly assess whether the claims have merit
• They can identify procedural defenses that may end the case early (improper service, wrong court, statute of limitations)
• They can file a motion to extend your response deadline if more time is needed
• Early case assessment often reveals whether settlement makes more sense than litigation

Many civil defense attorneys offer free initial consultations. Even if you ultimately decide to represent yourself, spending an hour with an attorney to understand your options is worthwhile.

Step 4: Review Your Insurance Coverage

Before you hire an attorney or spend money out of pocket, check whether you have insurance coverage for the claim. Many people don't realize their existing insurance may cover defense costs and judgment amounts:

• Homeowner's or renter's insurance — Often covers personal liability claims for accidents on your property, dog bites, and some defamation claims
• Auto insurance — If the lawsuit arises from a car accident, your auto liability coverage should apply
• Business insurance / general liability — If you're being sued for something related to your business
• Professional liability / errors and omissions (E&O) — For claims related to professional services
• Umbrella policy — Provides additional coverage above primary policies

Notify your insurer promptly — many policies have reporting requirements, and late notice can jeopardize coverage. If insurance applies, the insurer may provide and pay for defense counsel.

Step 5: Gather Relevant Documents and Evidence

While preparing your response, start organizing everything relevant to the claim:

• Any contracts, agreements, or written communications with the plaintiff
• Receipts, invoices, or financial records related to the dispute
• Photos, videos, or physical evidence
• Witness information — people who have relevant knowledge of the events at issue
• Your own contemporaneous notes or records from the time of the alleged incident

Don't destroy, delete, or alter any documents once you've been served — doing so can result in severe legal consequences called "spoliation of evidence."

Step 6: Filing Your Answer

The formal response to a complaint is called an answer. In your answer, you respond to each numbered paragraph of the complaint by admitting, denying, or stating that you lack sufficient information to admit or deny the allegation.

Your answer can also include:

• Affirmative defenses: Legal defenses that, if proven, defeat the claim even if the plaintiff's facts are true (e.g., statute of limitations, comparative fault, lack of standing, waiver)
• Counterclaims: Claims you have against the plaintiff arising from the same events
• Cross-claims: Claims against co-defendants

Failing to raise affirmative defenses in your answer can result in waiving them permanently. This is one of the most compelling reasons to have an attorney draft your answer rather than doing it yourself.

Alternatives to Filing an Answer

Depending on the circumstances, your attorney might recommend alternatives to a straight answer:

• Motion to dismiss: If the complaint has fundamental legal defects — it doesn't state a valid legal claim, the court lacks jurisdiction, or the statute of limitations has run — you can move to dismiss rather than answer.
• Settlement negotiations: Some cases are best resolved through negotiation before a formal answer is filed. Early settlement can avoid significant litigation costs.
• Motion for more definite statement: If the complaint is so vague that you can't understand what you're being accused of, you can ask the court to require the plaintiff to clarify.

What Happens After You File Your Answer

Once you've filed an answer, the case enters the pre-trial phase, which typically includes:

• Discovery: Both sides exchange information — written questions (interrogatories), document requests, and depositions
• Mediation: Many courts require parties to attempt mediation before trial
• Pretrial motions: Either party can file motions to narrow the issues or seek early judgment
• Trial — most civil cases never reach trial because they settle during the pretrial process

The timeline from service to resolution varies enormously — from a few months for small claims to several years for complex litigation.
