You can absolutely answer a debt collection lawsuit on your own. Most people who are sued for debt don't hire attorneys, and courts expect self-represented defendants (called "pro se" litigants). Here's how to do it step by step.
Get the right form. Many courts provide a fill-in-the-blank Answer form. Check your court's website, visit the self-help center at the courthouse, or search for "[your state] debt collection answer form." If there's no standard form, you can type your own on plain paper with the correct case caption (the names, case number, and court information from the summons).
Respond to each numbered paragraph. The complaint lists numbered allegations (paragraphs). For each one, you write: "Admitted" if the statement is true, "Denied" if it's false or you're not sure, or "Denied for lack of knowledge" if you don't have enough information to confirm or deny it. When in doubt, deny. The plaintiff has the burden of proving their claims.
List your affirmative defenses. These are legal reasons the plaintiff should lose even if the debt is real. Common ones for debt cases:
Statute of limitations has expired. The plaintiff lacks standing to sue (they can't prove they own the debt, which is common with debt buyers). The amount claimed is incorrect. The debt was already paid or discharged. You were not properly served. The debt is outside the applicable statute of limitations for your state.
You don't need to explain your defenses in detail at this stage. Just list them. You'll have the chance to argue them later.
File and serve your Answer. Make at least three copies of your completed Answer. File the original with the court clerk (in person or electronically if your court allows e-filing). Keep one copy for yourself. Send one copy to the plaintiff's attorney by certified mail with return receipt (the attorney's address is on the summons or complaint). Some courts also require a "proof of service" form confirming you sent a copy to the other side.
What happens next: After you file, the court will schedule a hearing or conference. Come prepared with any evidence you have: payment records, correspondence with the creditor, account statements. Many cases settle at this stage. If the plaintiff is a debt buyer, ask them to produce the original signed credit agreement and a complete chain of ownership. Many can't, and that can be enough to get the case dismissed.
Free resources: The National Consumer Law Center has guides for pro se defendants. Your state's legal aid website may have step-by-step instructions specific to your jurisdiction. SoloSuit.com is an online tool that generates Answer documents for a fee, but the same thing can be done for free with court forms.
