How to fight a debt collection lawsuit in the first 30 days

A complaint and summons can put you on a 20 or 30-day clock to respond before a default judgment. That first month is when you can still stop a one-sided case from becoming wage garnishment, bank account seizure, or another collection order.

The summons starts the clock

A debt collection lawsuit begins when a complaint is filed and served on you. That service matters because it is the moment the court process starts running. Pew’s 2023 brief on debt cases in three cities documented how much hangs on proper defendant notification. If the papers never reached you correctly, or reached you too late, that issue can matter just as much as the debt itself.

The complaint itself may also tell you less than you expect. Unverified complaints are common in debt collection lawsuits, so you should not assume the collector has already proved every allegation just because the case was filed. Public Counsel and the Federal Trade Commission both tell consumers to read the papers, identify the deadline, and do not let the case sit unopened.

Days 1 to 7: verify who is suing and what debt they claim

Use any contact from a collector to find out exactly what debt is being claimed, whether the collector is legitimate, and whether you really owe it. That is the Consumer Financial Protection Bureau’s starting point. Collection companies sometimes rely on old accounts, incomplete records, or mistaken identity, and the burden of sorting that out often falls on the consumer with the shortest deadline.

Do not assume that an old debt has vanished. Debt generally does not disappear because it is old, but many states limit how long creditors or collectors can use the courts to collect it. The CFPB warns that a collector may still try to collect a time-barred debt even if it may not be able to sue. A debt can be “owed” without being “sueable.”

The Fair Debt Collection Practices Act became effective on March 20, 1978, and the CFPB’s debt collection rule took effect on November 30, 2021. Together, those rules were meant to curb abusive, deceptive, and unfair collection practices while adding new consumer rights and new consumer risks around collection communications and time-barred debt.

Days 7 to 20 or 30: file an answer before the court deadline

This is the deadline that most often decides whether you lose by default. The time to answer can be short, depending on the state and the type of service. If you miss it, the collector can ask for a default judgment without having to win a live fight over the facts.

Filing an answer is not about admitting the debt is valid. It is about telling the court you are in the case and want to contest it. If you wait to “see what happens,” you may find out only after the judge has already entered judgment against you.

State rules vary widely, so the court that hears the case may look very different from one jurisdiction to another. Texas justice courts handle debt lawsuits worth up to $20,000, a limit reflected in Texas Law Help’s guidance, while other states use different procedures and different filing clocks.

What to put in your response

The first month is also the time to preserve defenses, even if you do not yet have every document you want. Common defenses include mistaken identity, payment, lack of proof, and expiration of the statute of limitations. If the collector says you owe a balance but cannot show the paperwork, or if the debt is too old to be sued on in your state, those issues belong in your response.

A strong answer is the quickest way to keep the case from turning into an automatic loss. Even if you are negotiating, disputing the amount, or trying to confirm whether the debt is yours, filing on time protects your position while you gather records. Waiting for the collector to “work with you” is risky because the court deadline keeps running whether or not the caller is being helpful.

If you lose by default, the case can expand fast

A default judgment does not just settle the lawsuit. Depending on state law, it can open the door to wage garnishment, bank account seizure, and other post-judgment collection remedies.

NCLC estimates that millions of Americans have debts in collection, mostly after a financial catastrophe, and that debt collectors are consistently a top source of consumer complaints. These lawsuits often land after job loss, medical crisis, family disruption, or another financial shock, and the legal system gives people only a narrow window to react.

Federal agencies, state attorneys general, and legal aid groups all publish guidance on what to do when a collector contacts you or sues you.
