Short answer
A debt buyer is a company that bought an old debt and now sues to collect it. In any case based on a credit card or brought by a debt buyer on a consumer debt, the complaint must: print the name of the signer; attach a Credit Card or Debt Buyer Collection Affidavit signed by the plaintiff or its agent (not its lawyer); attach the written contract or, if there is none, a document sent to you while the account was active (for a credit card, a charge-off statement is enough); and state that the suit was filed within the statute of limitations.
- Time limit to sue (written contract)
- 10 years

Defenses to know in Illinois
The statewide Affirmative Defenses form lists examples such as the plaintiff waiting longer than the law allows to sue, and the claim already being decided in an earlier case. The limit for written contracts is 10 years and for unwritten contracts 5 years. In credit card and debt buyer cases, missing paperwork under Rule 280.2 blocks a default judgment.

Find the plaintiff
Debt buyers sue under their own name, not the original creditor's.
Request the documents
A documents request letter asks for the contract and proof of ownership.
Answer on time
Illinois's deadline: It depends on your summons. If it gives a court date (claims of $50,000 or less), file your Appearance (and Answer, if required) before that date or go to court on that date; if you file only an Appearance, you have 10 days after the court date to file an Answer unless the judge sets another time.
Use the rules
Say if the plaintiff hasn't shown it owns the debt, or if the debt is too old.
