What to Do When Sued by Debt Collector and How to Fight Back

What Happens When a Debt Collector Sues You — And What to Do Right Now

If you're trying to figure out what to do when sued by a debt collector, here is the short answer:

1. Don't ignore the lawsuit. Ignoring it almost guarantees you lose automatically.
2. Check your deadline. You typically have 20–30 days from the date you were served to respond.
3. Verify who is suing you. It may be the original creditor or a debt buyer who paid pennies for your account.
4. File a written Answer with the court. This forces the collector to prove they own the debt, the amount is correct, and they have the legal right to sue.
5. Raise your defenses. The statute of limitations, wrong identity, and lack of documentation are all valid defenses.
6. Consider your options. You can fight, settle, or — in some cases — do nothing if you have no collectible assets.

Getting served with a court summons is scary. Most people freeze up or hope it goes away on its own.

It won't.

Research from The Pew Charitable Trusts found that more than 70% of debt collection lawsuits end in default judgments — simply because the person being sued never responded. A default judgment hands the collector the power to garnish your wages, freeze your bank account, or place a lien on your property. All without you ever getting a chance to fight back.

Here's the truth most people don't know: responding to a lawsuit does not mean you agree you owe the money. It simply means you're showing up and making the collector prove their case. And that's a much harder task for them than it looks — especially if the debt was sold to a third-party buyer who may not have the paperwork to back up their claims.

You have rights. You have options. And you have time — but not much of it.

I'm Brian Parker, founder of KillDebt. For over 30 years I've been in the courtroom fighting creditors, debt buyers, and collection law firms, and I've seen what happens when people know exactly what to do when sued by a debt collector — and what happens when they don't. This guide gives you the same step-by-step strategy I've used to protect thousands of consumers, broken down into plain language you can act on today.

Step 1: Stop and Assess—What to Do When Sued by Debt Collector Immediately

The moment a process server knocks on your door or you find a court summons in your mailbox, your heart rate spikes. Your immediate instinct might be to panic or throw the papers in a drawer and pretend they don't exist.

Don't do that.

Instead, take a deep breath. We need to transition from panic mode to strategic defense mode. Your first move is to organize your timeline. What you do in the first few days determines whether you maintain control or hand an easy victory to the debt collector. For a detailed breakdown of your immediate action items, look at our guide on Sued for a Debt? Here's Exactly What to Do in the First 7 Days.

First, confirm the lawsuit is real. Sometimes collectors send letters that look like court documents but are actually just aggressive collection notices. Check the court name, case number, and county. If you are unsure, call the official court clerk directly using a number you find on the county's official government website—not the phone number printed on the letters you received.

How to Determine If You Were Properly Served

Before a debt collector can proceed with a lawsuit, they must legally notify you. This is called "service of process."

In Florida and Michigan, proper service usually requires:

• Physical Service: A process server or sheriff physically hands the summons and complaint to you.
• Substitute Service: The papers are left at your home with a resident who is of suitable age (usually 15 or older in Florida, or a responsible adult in Michigan) after the server explains what they are.
• Certified Mail: In some small claims courts, service can be completed via certified mail, but it generally requires your signature or proof of delivery.

If the collector claims they served you but actually just threw the papers on your porch or left them with a neighbor, they may not have completed proper service.

However, do not use improper service as an excuse to ignore the case. If you discover a lawsuit was filed against you on the public court docket but you haven't been served yet, you are in what we call "garbage time." This is the strategic window where the lawsuit exists but your official response clock hasn't started ticking. You can use this time to gather documents, research the plaintiff, and prepare your defense without legal jeopardy.

Calculating Your Exact Response Deadline

Once you are properly served, the legal clock starts ticking immediately. Missing this deadline is the single biggest mistake consumers make.

Your deadline depends entirely on where you live:

• Florida: You typically have exactly 20 calendar days from the date of service to file a written response.
• Michigan: You have 21 calendar days if you were served in person, or 28 calendar days if you were served by mail or outside the state.

To protect yourself, calculate your exact deadline and mark it on your calendar. Then, establish a "default prevention date" exactly two days before the real deadline. This acts as your absolute safety buffer. If you haven't filed your response by your default prevention date, you must drop everything and get your paperwork to the courthouse immediately.

Step 2: Analyze the Lawsuit and Identify Weaknesses

Once you have established your timeline, it is time to dissect the lawsuit itself. You need to know exactly who is suing you and why. To see how this stage fits into the bigger picture, explore our article on the Debt Collection Lawsuit Timeline: What Happens Next After You're Served.

Start by identifying the Plaintiff (the entity suing you). There are two main types of plaintiffs in debt lawsuits:

1. The Original Creditor: This is the company you originally borrowed money from (e.g., Chase, Capital One, or Citibank).
2. A Junk Debt Buyer: These are companies like Midland Funding, Portfolio Recovery Associates, LVNV Funding, or Cavalry SPV. They buy charged-off debts in bulk for pennies on the dollar and then sue consumers for the full face value.

If you are being sued by a debt buyer, your chances of winning increase dramatically. Debt buyers purchase portfolios containing thousands of accounts, but they rarely receive the actual contracts, complete payment histories, or transfer documents for individual accounts. They rely on the expectation that you won't show up. If you force them to prove their case, they often fold.

Understanding the Plaintiff's Burden of Proof

In any civil lawsuit, the person suing has the "burden of proof." This means the debt collector must prove three distinct elements to win:

• Standing: They must prove they actually own your specific debt. This requires a complete "chain of title" showing the debt was legally transferred from the original creditor to any middleman, and finally to the plaintiff suing you.
• Accuracy: They must prove the exact dollar amount they are claiming is accurate, down to the penny, including any interest or fees.
• The Contract: They must prove that a valid legal agreement existed between you and the original creditor.

According to the FTC Consumer Advice on Debt Collection Lawsuits, collectors often lack the necessary documentation to back up these claims at the time of filing. If they cannot produce the original signed contract or the complete chain of title, they cannot meet their burden of proof.

Spotting FDCPA Violations to Use as Leverage

As you review the history of your communications with the collector, look closely for violations of the Fair Debt Collection Practices Act (FDCPA). Under federal law, debt collectors are strictly prohibited from engaging in abusive, deceptive, or unfair practices.

Common violations include:

• Calling you before 8:00 AM or after 9:00 PM.
• Contacting you at work after you told them your employer prohibits personal calls.
• Threatening legal actions they do not actually intend to take (such as threatening to arrest you or garnish your wages before they have a court judgment).
• Continuing to contact you after receiving a formal cease-and-desist letter.
• Misrepresenting the character, amount, or legal status of any debt.

If a collector broke the law, you can use these violations as powerful leverage in your defense. Under the FDCPA, you have the right to sue a collector in federal or state court within one year of the violation. For more tips on documenting these illegal actions, check out the Florida Attorney General Debt Collection Guide and learn how to What to do if a Debt Collector Sues or Contacts You.

Step 3: Draft and File Your Formal Answer

Now that you've analyzed the lawsuit, it is time to take action. You must draft and file a formal written Answer with the court. An Answer is your official response to the allegations listed in the complaint. To learn how to structure this document correctly, review our comprehensive guide on How to Answer a Debt Summons.

Filing an Answer keeps you active in the case, prevents an automatic default, and forces the debt collector to schedule a court hearing where they must present actual evidence.

How to Respond to Each Allegation in the Complaint

A lawsuit complaint is structured as a list of numbered paragraphs. When drafting your Answer, you must respond to each numbered paragraph individually.

For every single allegation, you have three options:

1. Admit: You agree that the statement in the paragraph is 100% true (e.g., admitting your name and address).
2. Deny: You dispute the statement. This is your default setting for any claim regarding the debt itself, the amount owed, or the collector's right to sue you. Denying an allegation does not mean you are lying; it simply means you are demanding the collector prove it with admissible evidence.
3. State Lack of Knowledge: You do not have enough information to know if the statement is true (e.g., when a debt buyer claims they purchased your account on a specific date). This has the legal effect of a denial.

As outlined in How to answer a debt collection summons: A practical rights guide - Consumer Attorneys, you should avoid writing long, emotional stories in your Answer. Keep your responses short and objective. For a visual template of how this looks, you can download our Sample Answer to Debt Collection Lawsuit.

Raising Affirmative Defenses in Your Answer

An Affirmative Defense is a legal reason why the plaintiff shouldn't win, even if the basic facts of their complaint are true. If you do not raise your affirmative defenses in your initial Answer, you legally waive your right to bring them up later in the case.

Common affirmative defenses in debt collection lawsuits include:

• Statute of Limitations: The legal time limit for suing on the debt has expired. In Florida, the statute of limitations for most consumer debts (including credit cards) is 5 years. In Michigan, the statute of limitations is 6 years.
• Lack of Standing: The plaintiff has failed to show a clear chain of title proving they actually own the debt.
• Prior Payment or Settlement: You already paid the debt in full or settled it with the original creditor.
• Identity Theft / Mistaken Identity: The debt belongs to someone else, or your identity was stolen to open the account.

Step 4: Avoid the Default Trap and Protect Your Assets

If you do nothing when sued, the court will issue a Default Judgment against you. This is the "Default Trap," and it is exactly what debt collectors rely on. Once a collector has a default judgment, they gain powerful legal mechanisms to collect the money directly from you. Our guide on What to Do When Sued by a Debt Collector: Complete First Steps Guide explains how to protect your financial life from these aggressive tactics.

If a judgment is entered, the collector can pursue:

• Wage Garnishment: Taking a percentage of your paycheck before it ever hits your bank account.
• Bank Account Levies: Freezing your bank account and seizing whatever funds are inside.
• Property Liens: Placing a legal claim against your home or vehicle, preventing you from selling or refinancing without paying the debt first.

What to Do When Sued by Debt Collector but You Are Judgment Proof

Sometimes, a consumer's financial situation is so limited that they are considered "judgment proof." Being judgment proof does not mean you cannot be sued; it simply means that even if the collector wins a judgment, they cannot legally seize your income or assets because they are protected by federal or state exemptions.

Exempt sources of income and assets include:

• Social Security benefits.
• Supplemental Security Income (SSI).
• Veterans' benefits.
• Disability benefits.
• Child support and alimony.
• Basic personal property up to state-specific limits.

If your only source of income is exempt, you must still respond to the lawsuit to assert these protections. Do not assume the court or the collector will protect your funds automatically.

The Role of Counter-Affidavits in Your Defense

If you are being sued in Michigan, you must pay close attention to how the collector styles their lawsuit. Many collectors file what is known as an "Account Stated" claim. Under Michigan law (MCL 600.2145), if a plaintiff attaches a sworn affidavit of the amount owed to their complaint, the allegations are legally deemed true unless the defendant files a written counter-affidavit denying the debt.

If you fail to file a notarized counter-affidavit along with your Answer in Michigan, you can lose the case automatically on a summary disposition, even if you filed a basic Answer. For detailed guidance on navigating this specific Michigan court rule, consult the resources at I Have Been Sued to Collect a Debt.

Step 5: Decide on Your Resolution Strategy

Once you have filed your Answer and protected yourself from a default judgment, you need to choose your long-term resolution strategy. You have two primary paths: fight the case in court to get it dismissed, or negotiate a settlement out of court. For a deep dive into both paths, read our Fight Debt Collection Lawsuit: Complete Guide.

Negotiating a Safe Settlement Out of Court

If you decide to settle the debt, do not call the collector and make an emotional offer. You must approach negotiations strategically.

As discussed in Sued by a Debt Collector? A Calm, Practical Guide to Responding (and What to Document) - Consumer Attorneys, you should follow these rules for safe negotiation:

• Start Low: Begin your negotiations by offering a lump-sum payment of 30% to 50% of the total claimed amount. Be prepared to negotiate upward, but never offer more than you can realistically afford.
• Use the Magic Words: Whenever you communicate with a collector about settlement, explicitly state: "This conversation is for settlement purposes only under Rule 408." This prevents the collector from using your statements or offers as an admission of guilt in court.
• Get It in Writing: Never send a single penny until you have a signed, written settlement agreement. The agreement must explicitly state that the payment resolves the debt in full and that the lawsuit will be dismissed with prejudice (meaning they can never sue you for this debt again).

When to Hire an Attorney vs. Going DIY

Many consumers believe they must hire an expensive defense attorney to handle a debt lawsuit. While having legal representation is helpful, attorney fees can easily exceed the total amount of the debt itself.
