Yes, you can absolutely be sued for a debt and never find out until it is too late. It happens when a collector files a lawsuit, the court paperwork is never properly delivered to you, and the court enters a "default judgment" because you did not show up to defend yourself. Many people first discover this when a paycheck gets garnished or a bank account is suddenly frozen. The good news: if you were never properly served, you usually have a path to ask the court to undo that judgment.
How You Can Be Sued and Never Know
When a debt buyer or collector decides to sue, they file a complaint and the court issues a summons. The law requires that you be personally notified of the lawsuit through a formal process called "service of process." The whole point is fairness: you cannot defend a case you do not know exists. If you are properly served and ignore the lawsuit, the consequences are on you. But when service is botched or faked, the system breaks down.
There are honest reasons you might miss a lawsuit. The papers may have gone to an old address, a previous apartment, or a relative's house. Collectors often use stale address information from old accounts. Mail gets lost. People move. In those situations, the lawsuit moves forward without you, and the first sign of trouble is often a frozen account or a garnished paycheck.
What 'Sewer Service' Means
"Sewer service" is the nickname for a specific kind of fraud: a process server claims to have delivered the lawsuit papers to you but never actually did, sometimes literally throwing them in the sewer. The server signs a sworn statement (an "affidavit of service") saying you were notified, the court believes it, and a default judgment follows. You had no real chance to respond because you never knew you were sued.
This is not a rare urban legend. Regulators have pursued large cases against process-serving companies and debt collectors for systematic sewer service, where thousands of judgments were built on false service affidavits. Both the Federal Trade Commission (FTC) and the Consumer Financial Protection Bureau (CFPB) have taken action against abusive debt-collection litigation practices, and state Attorneys General have prosecuted server fraud. If your judgment rests on a fake service record, that judgment can often be challenged.
What a Default Judgment Actually Does
A default judgment is a court ruling against you that you never contested. Once entered, it gives the creditor powerful collection tools that vary by state but commonly include:
Wage garnishment — taking a portion of your paycheck directly from your employer.
Bank account levy or freeze — seizing funds from your accounts, which is why a frozen account is such a common wake-up call.
Liens — a legal claim placed against property you own.
Post-judgment interest — the balance keeps growing over time.
Federal law does protect certain income from garnishment. Social Security, SSI, veterans' benefits, and other federal benefits are generally exempt, and there are federal rules requiring banks to protect a couple of months of directly deposited federal benefits from being frozen. State law often shields additional money and property (for example, a portion of wages, or specific exemption amounts). The exact exemptions and how you claim them vary by state, so do not assume your frozen funds are all fair game.
If Your Account Was Just Frozen: Move Fast
A frozen account or garnishment is a crisis with short fuses attached. Here is what to do:
Find out who sued you and in which court. The freeze paperwork, garnishment notice, or your bank can tell you the case name, court, and case number. With the case number you can pull the docket.
Get the court file. Look at the affidavit of service. Where do they claim they served you? On what date? Does the description of the person served even match you? Errors here are the heart of a sewer-service challenge.
Identify exempt funds immediately. If the frozen money includes Social Security, disability, veterans' benefits, child support, or wages, those may be protected. Many states have a fast "claim of exemption" process — but it usually has a tight deadline.
Document everything. Save the freeze notice, bank statements showing the source of deposits, your lease or proof of where you actually lived on the service date, and any mail forwarding records.
Vacating (Undoing) a Default Judgment
The main remedy for a judgment you never knew about is a motion to vacate the default judgment (sometimes called a motion to set aside or reopen). You are asking the court to cancel the judgment so the case can actually be heard. Common grounds include:
Improper or no service — you were never properly notified, so the court arguably never had authority over you. This is often the strongest argument.
Excusable neglect — a legitimate reason you missed the deadline, paired with showing you have a real defense.
You don't owe it — wrong person, already paid, identity theft, or the debt is past the statute of limitations.
Deadlines to vacate vary a lot by state and by the grounds you use. Some states give a generous window when service was defective, because a judgment without proper service may be considered void. Others impose strict, short time limits for other grounds. Because this varies by state, do not rely on a number you read online — confirm the actual deadline for your court. Acting quickly always helps.
A practical note: when you file a motion to vacate, many courts will let you ask to freeze or release the collection (lift the levy or pause garnishment) while the motion is pending. Ask the clerk how to request that relief in your jurisdiction.
Can You Be Sued for the Same Debt Twice?
Generally, no — a legal principle called res judicata (claim preclusion) stops a creditor from suing you again over the same debt once a court has issued a final judgment. If a collector already won (or lost) a judgment on a specific account, they cannot file a brand-new lawsuit on that same account to get a second bite at the apple.
But people get confused for real reasons:
The debt gets sold. A new collector may buy the account and contact you, but if there is already a judgment, they are enforcing the old one, not creating a new lawsuit.
Two different debts look similar. Two separate credit cards from the same bank are two different debts. Suing on each is not suing "twice."
Refiling after a dismissal without prejudice. If an earlier case was dismissed "without prejudice" (not decided on the merits), a collector may sometimes refile. A dismissal "with prejudice" generally ends it for good.
Being sued or dunned repeatedly on a debt you already resolved, or that was already reduced to judgment, can raise issues under the Fair Debt Collection Practices Act (FDCPA), the federal law that bars deceptive and unfair collection conduct. The FDCPA is enforced by the FTC and the CFPB, and it also lets you sue collectors yourself. If a debt is showing up wrong on your credit report after a judgment is vacated or paid, the Fair Credit Reporting Act (FCRA) gives you the right to dispute it.
If You Are Properly Served: Don't Ignore It
The flip side matters. If you do receive a summons and complaint, the worst move is to do nothing. You typically have a strict, short window — often counted in days — to file a written "answer" with the court. Missing it is exactly how default judgments happen. The deadline is set by your state's rules, so check the summons and the court's instructions carefully. Filing an answer, even a simple one, preserves your defenses, including whether the collector can actually prove you owe the debt and own the right to collect it.
When to Talk to a Lawyer
This is general information, not legal advice, and a frozen account or garnishment is a high-stakes situation where talking to a consumer-protection or debt lawyer is often worth it. Many handle FDCPA and improper-service cases on contingency or offer free consultations, and if a collector broke the law, they may be able to recover fees from the other side. A local legal aid office is a strong option if cost is a concern. A lawyer can move fast on a motion to vacate, a claim of exemption, and an emergency request to release your funds — and those filings often have deadlines that are easy to miss on your own. If your bank account was just frozen or your wages are being garnished over a debt you never knew you were sued for, getting advice quickly is one of the most protective steps you can take.
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.
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.
Frequently asked questions
Can I be sued and not know about it?
Yes. If the lawsuit papers are sent to an old address or a process server falsely claims to have delivered them ("sewer service"), a court can enter a default judgment against you without your knowledge. People often find out only when a bank account is frozen or wages are garnished. If you were never properly served, you can usually ask the court to vacate the judgment.
Can I be sued for the same debt twice?
Generally no. Once a court issues a final judgment on a debt, a legal rule called res judicata bars a new lawsuit over that same debt. Confusion arises when a debt is sold to a new collector enforcing the old judgment, when two separate accounts look similar, or when an earlier case was dismissed "without prejudice" and can be refiled.
What should I do first if my bank account was frozen?
Find out who sued you and in which court using the freeze notice or your bank, then pull the court file and look at the affidavit of service. Immediately identify any exempt funds like Social Security, disability, or veterans' benefits, and gather proof of where you lived when service was supposedly made. Many states have a fast claim-of-exemption process with tight deadlines.
How do I undo a default judgment I never knew about?
You file a motion to vacate (set aside) the default judgment, asking the court to cancel it so the case can be heard. Improper or fake service is often the strongest ground, because a judgment entered without proper notice may be void. Deadlines vary by state and by the grounds you use, so confirm your court's specific rules and act quickly.
Is the money in my frozen account protected?
Some of it may be. Federal law generally protects Social Security, SSI, and veterans' benefits, and banks must safeguard a couple of months of directly deposited federal benefits from freezing. Many states shield additional wages and property. You typically must file a claim of exemption to get protected funds released, and that varies by state.
