Sued for a Debt You Don't Recognize: What to Do

If you've been sued for a debt you don't recognize, the single most important thing to do is respond to the court in writing by the deadline stated in your summons — usually somewhere between 14 and 35 days depending on your state and court, so check your paperwork immediately. Ignoring the lawsuit does not make it go away; it almost always leads to a default judgment against you, which the creditor or debt buyer can then use to garnish wages or freeze bank accounts. You have real defenses available, including demanding proof that the plaintiff actually owns the debt and asserting that the statute of limitations has expired, but you can only raise them if you show up and answer.

Why This Happens: Debt Buyers and Bad Records

Being sued for a debt you don't recognize is extremely common, and it doesn't automatically mean fraud or identity theft (though it can). Most of these lawsuits are filed by debt buyers — companies that purchase large bundles of old, charged-off accounts from banks and original creditors for pennies on the dollar, then sue on them. Because the debt has changed hands multiple times, the documentation is often thin, the amount may be wrong, the debt may not even be yours, or it may be too old to legally collect through a lawsuit. Debt buyers rely heavily on the fact that most people served with a lawsuit never respond. When no one answers, the buyer wins automatically, regardless of whether they could have actually proven the debt was valid.

The Federal Baseline: What Actually Governs Debt Collection

Before getting into the lawsuit itself, it helps to understand which federal laws apply to how you were contacted and how the debt was collected, because violations of these laws can sometimes become leverage or even a counterclaim.

The primary federal law is the Fair Debt Collection Practices Act (FDCPA), which applies to third-party debt collectors and debt buyers (generally not to original creditors collecting their own debts). The FDCPA prohibits harassment, threats, false statements about the amount or status of a debt, and misrepresenting that a lawsuit will be filed when it won't be. The Consumer Financial Protection Bureau (CFPB) has implemented detailed rules under the FDCPA known as Regulation F (12 CFR Part 1006). Regulation F sets a general limit of seven calls within a seven-day period per debt, restricts calling again within seven days after a phone conversation about that debt, and creates specific rules for contacting consumers by email, text message, and social media, including required opt-out mechanisms for electronic communications. Regulation F also created the "limited-content message," a narrowly defined voicemail format collectors can use that avoids counting as a communication that could reveal the debt to someone else who hears it.

Other federal laws that may be relevant depending on your situation include the Fair Credit Reporting Act (FCRA), which governs how the debt can be reported to credit bureaus and gives you the right to dispute inaccurate information; the Telemarketing Sales Rule, which bans debt-relief companies from charging upfront fees before actually settling or reducing your debt; the Credit Repair Organizations Act (CROA), which regulates companies that promise to fix your credit; the FTC's Cooling-Off Rule (16 CFR Part 429), which lets you cancel certain in-person sales contracts within three days; the E-Sign Act, which governs whether electronic signatures and disclosures are legally valid; and the general FTC Act prohibition on deceptive and unfair practices, including deceptive pricing. These laws are enforced by the Federal Trade Commission (FTC), the CFPB, and state Attorneys General, and several of them (notably the FDCPA) also let you sue a violator directly in some circumstances.

None of these federal laws control the deadline to answer a lawsuit — that comes from your state's civil procedure rules and the specific court where you were sued, which is why the exact number of days varies so much from one state (and even one county) to another.

The Answer Deadline Is the Most Urgent Thing in the Entire Process

When you're served with a lawsuit — meaning someone officially delivers the summons and complaint to you, or in some states leaves it with a household member or posts it and mails a copy — the clock starts running immediately. Your summons will state a deadline to file a written response, called an "Answer," with the court clerk. This is a hard, calendar-driven deadline set by state law and local court rules, not a suggestion. Depending on where you live and how you were served, it may be as short as roughly two weeks or as long as around a month; some states also have different deadlines depending on whether you were served in person, by mail, or by publication. Because this varies by state, the only reliable source for your specific deadline is the paperwork you were served and your local court's rules or clerk's office.

Miss that deadline, and the plaintiff can typically ask the court to enter a default judgment against you. A default judgment means the court rules in the creditor's favor automatically because you never showed up to contest anything — not because they proved the debt was real, valid, or actually yours. Once a default judgment is entered, the creditor generally gets the same collection powers as if they'd won at trial: they can often garnish your wages, place a lien on property, or freeze a bank account, subject to your state's exemption laws. Undoing a default judgment after the fact is possible in many states but is far harder, slower, and more expensive than simply answering on time in the first place.

Step by Step: What to Do the Moment You're Served

• Read every page of what you were served. Note the court name, case number, the plaintiff's exact name, and — critically — the stated deadline to respond.
• Do not ignore it, and do not simply call the plaintiff's attorney and assume that settles it. A phone call or letter to the law firm does not stop the case or the deadline; only filing something with the court (or having a lawyer do so) protects you.
• Confirm the deadline with the court clerk if anything is unclear. Clerks can tell you filing procedures and deadlines (they generally can't give legal advice), and many courts post self-help instructions and Answer forms online for debt-collection cases.
• File a written Answer before the deadline. At minimum, this should respond to each claim in the complaint and assert any defenses you may have (see below). Some states have simplified fill-in-the-blank Answer forms specifically for debt collection cases — ask the clerk if one is available.
• Keep copies of everything — the summons, complaint, your Answer, proof of filing, and any mail or documents you receive afterward.
• Request documentation from the plaintiff proving the debt is valid, accurate, and actually belongs to you (more on this below).

Demand Proof: Standing and Ownership of the Debt

When a debt buyer sues, it must prove it actually owns the specific debt and has legal standing to collect it — not just that a debt with your name on it exists somewhere. This is one of the most effective defenses in these cases because debt-buying involves chains of sale where documentation is frequently incomplete, lost, or attached to the wrong account.

You can challenge this by:

• Requiring the plaintiff, through the discovery process or a formal request in your Answer, to produce the original signed account agreement or application, an unbroken chain of assignment or bill of sale showing the debt passed from the original creditor to the current plaintiff, and a full account statement history showing how the balance was calculated.
• Pointing out gaps: if the plaintiff can't produce the original agreement, can't show the chain of custody for the account, or the numbers don't match what you actually owed, that undermines their ability to win.
• Disputing the debt directly, in writing, if a collector contacts you before or during the suit — under the FDCPA, a written dispute within 30 days of the initial collection notice requires the collector to verify the debt before continuing collection, and that verification can become useful evidence (or reveal weaknesses) in the case.

You are allowed to say, in your Answer, that you lack sufficient information to admit or deny that the debt is yours or that the amount is accurate — this is a standard, legitimate response when you genuinely don't recognize the account, and it forces the plaintiff to actually prove its case rather than winning by default.

Raising the Statute of Limitations

Every state sets a time limit — a statute of limitations — on how long a creditor or debt buyer has to sue over a debt, typically measured from the date of the last payment or the date the account was first missed, depending on state law. These time limits vary significantly by state and by the type of debt (credit card, medical, promissory note, and so on), so there is no single nationwide number. If the statute of limitations has run out, the debt itself may still technically exist, but the creditor generally loses the ability to win a lawsuit over it — provided you actually raise the statute of limitations as a defense in your Answer. In most states, courts will not apply this defense automatically; if you don't raise it, you can lose even on a debt that's legally too old to sue over. Be cautious about making any payment on an old debt before you've sorted out the timeline, because in some states even a small payment or written acknowledgment can restart the clock.

What to Document Along the Way

• The date you were served and by what method (in person, mail, posting, etc.)
• Every letter, call, text, or email from the collector or their attorney, including dates and the content of the message
• Any payments you've ever made on the account in question, with dates and amounts
• Copies of your credit reports showing how the debt is listed, and any disputes you've filed with the credit bureaus under the FCRA
• The court's case file, including anything the plaintiff files, so you know what they're relying on

When It's Worth Talking to a Lawyer

Many people successfully answer a debt lawsuit and negotiate or defend it on their own, especially with the help of court self-help resources or a legal aid organization. But it's worth talking to a consumer-law attorney if the amount is large, if you're not confident about the deadline or filing requirements in your court, if you suspect real identity theft rather than just a debt-buyer paperwork problem, if wages or bank accounts are already at risk, or if you want help evaluating whether the collector's conduct itself violated the FDCPA or Regulation F (which could give you leverage or even a counterclaim). Many consumer attorneys offer free initial consultations for debt-defense cases, and legal aid organizations in many areas specifically handle debt-collection defense at low or no cost.

Key Takeaways

The deadline in your summons is real and it is short — find it and calendar it the day you're served. Never ignore a debt lawsuit hoping it disappears, because a default judgment hands the creditor collection power without ever proving their case. You have the right to demand real proof of who owns the debt and how much is actually owed, and you have the right to raise the statute of limitations if the debt is too old — but both of those defenses only work if you show up and answer.

Know the law

A debt collector must prove you owe the debt and sue within your state’s statute of limitations — defenses that often win when you respond.

Key federal laws:

• Fair Debt Collection Practices Act (FDCPA), 15 U.S.C. § 1692 et seq.

Where to get help or file a complaint:

• Consumer Financial Protection Bureau (CFPB) — submit a complaint

Your state matters too. Federal law is the floor — your state sets the statute of limitations on debt, garnishment and exemption limits, payday and repossession rules, and has its own Attorney General and consumer-protection laws. Always check your state’s rules. This is general legal information, not legal advice.
