If you get a summons and petition informing you that you’ve been sued for a debt in Missouri, you need to respond by following the court instructions on the summons form. This often means: 1. Drafting an answer form. 2. Addressing each of the debt collector’s claims against you. 3. Listing your defenses and affirmative defenses. 4. Filing your answer form with the court and serving a copy on the person suing you. The summons return date indicates how long you have to repond to the lawsuit. It's typically between 10 and 60 days.

How Do Debt Collection Lawsuits in Missouri Work?
If a creditor or debt collector believes you owe money, they’ll usually try to contact you by phone or mail first. If those efforts don’t work, they may file a lawsuit to try to recover the money.
In Missouri, these lawsuits are typically filed in the circuit court in the county where you live. Circuit courts handle many types of cases, so they’re divided into different divisions. Debt collection cases are often filed in either the small claims division or the associate circuit division.
The small claims court handles cases involving $5,000 or less. The associate circuit court usually handles civil cases involving $25,000 or less. Many consumer debt collection cases in Missouri are filed in the associate circuit court.
If a lawsuit is filed against you, you’ll receive official court documents notifying you of the case. In Missouri, these documents are usually called a summons and a petition. In some other states, the petition is called a complaint.
What Is a Summons and Petition?
A summons is an official court document notifying you that someone has filed a lawsuit against you. It’s usually delivered with another document called a petition.
The petition explains why the person suing you (called the plaintiff) believes you owe money and how much they claim you owe. It also asks the court to enter a judgment. A judgment is a court order that may require payment if the plaintiff wins the case.
The summons includes other important information, such as:
The name of the circuit court handling your case
The plaintiff’s name and their attorney’s name, if they have one
Instructions for responding to the lawsuit
A deadline to file your response
A warning about what may happen if you don’t respond
🗓️ In Missouri associate circuit court cases, you generally have 30 days from the date you’re served to file a written response.
How Do You Respond to a Missouri Court Summons for Debt Collection?
If you’re sued in Missouri, start by reading the summons carefully. The summons explains which court is handling the case and what steps are required. The process for responding can vary depending on the type of court and the county.
For example, in some small claims cases, the summons may direct you to appear at a hearing on a specific date and time. In associate circuit court cases, you generally must file a written answer within the deadline listed in the summons. The exact instructions for your case will be included in the documents you receive.
The information below is meant as a general guide. If you get stuck at any point, you can call or visit the courthouse listed on your summons and ask to speak with the court clerk. Clerks can help explain court processes, forms, and procedures. Just keep in mind that they can’t give legal advice.
Step 1: Draft an Answer Form
If you’re required or have the option to file a written answer, you may need to prepare the document yourself. Missouri courts don’t provide a standardized fill-in-the-blank answer form for most debt collection cases, so many people draft their own response.
✨ If you’re worried about responding on your own but can’t afford a lawyer, you may want to explore using Solo to prepare your answer for a small fee. Solo has helped more than 350,000 people respond to debt lawsuits and offers a 100% money-back guarantee if you’re not satisfied.
Solo is an affiliate partner, which means Upsolve may earn a small commission if you choose to use their paid service. This helps keep our services free.
✅ Generally, an answer includes:
Case information: the case number, the names of the parties (plaintiff and defendant), and the name of the court listed on the summons
Responses to the allegations: a response to each numbered paragraph in the petition (more on this in the next section)
Affirmative defenses: any legal reasons you believe you shouldn’t have to pay the debt, such as an expired statute of limitations, mistaken identity, or prior payment
Your signature and the date
Court documents usually need to follow certain formatting rules to be accepted. Local court rules may address things like margins, font size, and paper format. If you’re unsure about formatting requirements, you can review your local court’s rules or contact the court clerk for procedural guidance.
Some courts also require additional documents, such as a certificate of service or a statement verifying that the information in your answer is true.
Step 2: Address Each Complaint/Allegation
The petition you receive will list the plaintiff’s claims against you in numbered paragraphs. These paragraphs act as a guide for preparing your response.
📝 When you draft your answer, respond to each numbered paragraph and match the same numbering used in the petition. This helps the court clearly see how you’re responding to each specific claim.
There are generally three response options:
Admit: You agree the statement is true.
Deny: You disagree with the statement or believe the plaintiff hasn’t proven it.
Lack knowledge: You don’t have enough information to admit or deny the statement.
➡️ Many people use the third “lack of knowledge” option when they don’t recognize certain details, such as the exact balance owed or whether the plaintiff truly owns the debt. When you respond this way, the debt collector or their lawyer usually has to provide proof to support that claim before the judge can rule on it.
Step 3: Raise Your Defenses
If you believe something in the petition isn’t true, or if important information was left out, you can include that in your defense. This is your opportunity to explain why the plaintiff shouldn’t win the case.
There are two main types of defenses. A regular defense is simply saying, “What the debt collector said isn’t true.” An affirmative defense is different. It means there’s another legal reason the debt collector shouldn’t win the case — even if some of the statements in the petition are accurate.
🛡️ Here are some common affirmative defenses used in debt collection lawsuits:
Expired statute of limitations: The law limits how long a creditor can wait before filing a lawsuit. If too much time has passed, the case may no longer be valid.
Mistaken identity: Sometimes the wrong person is sued due to an administrative error or other mistake.
Incorrect debt amount: If the balance listed in the petition doesn’t seem accurate, the judge may call the entire claim into question.
Prior payment, settlement, or bankruptcy: If you already paid the debt, reached a settlement, or filed bankruptcy and the debt is included in your ongoing case or was included in your discharge paperwork, that may prevent the collector from moving forward.
If the debt collector violated state or federal debt collection laws while trying to collect from you, that may also qualify as an affirmative defense.
📂 As you think through your defenses, it can help to gather documents that support your position. This might include account statements, payment records, receipts, loan or credit card agreements, contracts, settlement letters, or bankruptcy paperwork.

Step 4: Make Copies of Your Answer and Complete Any Other Required Forms
After you finish your answer, make at least two copies. You’ll file the original with the court, keep one copy for your records, and send one to the plaintiff or their attorney.
In many courts, you’ll also need to complete a certificate of service or a similar form. A certificate of service is a short document that confirms you delivered (served) a copy of your answer to the plaintiff. It tells the court when and how you sent it.
Court procedures can vary, so check with the court clerk listed on your summons if you need to confirm the filing and service requirements. The clerk can explain whether any additional forms are required and how to properly deliver your answer.
Step 5: File Your Forms With the Court Clerk Within 30 Days
In Missouri, you generally have 30 days from the date you were served to file your answer. Meeting this deadline is important. If you don’t file on time, you risk losing the case.
You can file your answer in person at the circuit court listed on your summons or by mail. If you file in person, submit the original and bring a copy for the clerk to timestamp. Keep the stamped copy for your records.
📫 If you file by mail, send the original and include a copy for the clerk to stamp and return. Many people also include a self-addressed envelope with prepaid postage so they can receive their stamped copy back for proof of filing.
Step 6: Serve a Copy of the Answer on the Plaintiff
To keep the process fair, courts require both sides to share important filings with each other. That’s why you received a copy of the summons and petition. The same requirement applies to your answer.
📩 Missouri law requires you to send a copy of your answer to the plaintiff. This step is called “service.” In most cases, service is completed by mailing the answer to the address listed for the plaintiff or their attorney on the summons. Some courts may also allow personal delivery. Many people use certified mail so they have proof that the answer was sent and delivered.
🗓️ Missouri law also requires that documents you serve be filed with the court. You can file your answer before serving it or within five days after service. To keep the process straightforward, many people file and serve their answer at the same time.
What Happens After You Respond to the Lawsuit?
After you file your answer with the court, the case moves forward. You may receive:
A notice scheduling a pretrial conference or court hearing
A notice of a mediation session, where a neutral third party tries to help both sides reach an agreement before trial
A settlement offer from the person or company suing you
If you believe you owe the debt and don’t think you have a strong defense, you can contact the collector to try to negotiate a debt settlement agreement. In a settlement, the creditor agrees to accept less than the full amount owed to resolve the case.
⚠️ Keep in mind that negotiating doesn’t automatically pause the lawsuit. Court dates and deadlines still apply unless the court enters an order changing them. Missing a required hearing or deadline can lead to a judgment being entered against you.
As mentioned previously, the exact next steps will depend on the court handling your case. Review every notice you receive from the court carefully so you understand whether any action is required. If anything is unclear or you need to reschedule court appearances, speak with the court clerk as soon as possible.
What Happens if You Don’t Respond to the Lawsuit?
Some debt collectors file lawsuits expecting that people won’t respond. When no response is filed, the court can enter a default judgment. A default judgment is a court order issued by the judge because the lawsuit wasn’t answered. Once that happens, the debt collector may gain stronger tools to collect the debt, such as garnishing your wages or freezing money in your bank account.
That’s why responding to a summons and petition matters. Filing an answer allows you to take part in the case and requires the plaintiff to prove its claims instead of winning automatically. The act of responding puts you in a stronger position to win the debt collection lawsuit.
If a judge already entered a default judgment against you, you may be able to file a motion to vacate (cancel) the judgment and ask the court to reopen the case. Filing a motion simply means submitting a formal request to the court.
If you’re in this situation, you can contact the court clerk, explain what happened, and ask about the process for requesting that the judgment be set aside. Clerks can’t give legal advice, but they can explain whether a process exists to contest the judgment and what forms the court requires.
