Complaint (Court Filing)

Updated AUG 17, 2026Credit Defense Hub Editorial Team Pending professional review1 official source

Short answer

A complaint is the document a creditor, debt buyer, or collector files with a court to start a debt lawsuit. It names who is being sued, describes the debt, and states what the plaintiff claims you owe.

Why it matters

The complaint is the plaintiff's side of the story, not a finding by the court that you owe anything. It lists the allegations you will respond to in your answer, and it must generally be proven with evidence if the case is contested. Complaints filed by debt buyers sometimes contain errors, such as the wrong amount, an account that is not yours, or a debt past the statute of limitations. A complaint usually arrives with a summons that sets the deadline to respond. Because failing to respond can lead to a default judgment, garnishment, or a levy, people served with a complaint often review it carefully and consult a debt-defense attorney or legal aid office.

Example

Ben receives a complaint from a debt buyer alleging he owes a specific balance on a charged-off account. Reading it closely, he notices the amount is higher than he remembers and the account number is unfamiliar. The complaint is only the plaintiff's claim, so Ben prepares to respond by the summons deadline and disputes the details he believes are wrong. Because a judgment could follow, he also talks with a legal aid attorney about the allegations.
