Defenses in Credit Card Collection Lawsuits

Most credit card collection lawsuits end in default judgments — not because the plaintiffs' cases are strong, but because defendants never respond. That is a costly mistake in California, where the law hands credit card defendants a genuine set of defenses, especially when the plaintiff is a debt buyer. Here are the defenses that matter most and how they work.

First: respond, or nothing else matters

In California you generally have 30 days after service of the summons and complaint to file a response. Miss it and the plaintiff can request your default, then a default judgment enforceable through wage garnishment and bank levies. Most defenses below will be waived or wasted if you do not appear. Calendar the deadline the day you are served.

Statute of limitations

Credit card claims in California are generally governed by the four-year limitations period for written contracts, Code of Civil Procedure § 337, usually accruing when a required payment is missed, although accrual depends on the claim and account history. If the plaintiff sued outside that window, the claim is time-barred — and if the plaintiff is a debt buyer, filing suit on a time-barred consumer debt is itself prohibited by Civil Code § 1788.56. Two cautions: the defense must be raised in your answer or it is forfeited, and a partial payment or signed written acknowledgment made before the limitations period expires can restart the clock under CCP § 360. Once the limitations period on a consumer debt has expired, however, a subsequent payment or acknowledgment does not revive or extend it under Civil Code § 1788.14.

Standing and chain of title

If the named plaintiff is not your original card issuer, it must prove it actually owns your specific account. Charged-off portfolios change hands repeatedly, and the paperwork often consists of spreadsheets and generic bills of sale that never mention your account number. California's Fair Debt Buying Practices Act sharpens this defense: under Civil Code § 1788.58, a debt buyer's complaint must allege ownership, the chain of title from the charge-off creditor, the charge-off balance, and an itemization of post-charge-off interest and fees. Under § 1788.60, even a default judgment requires admissible business records proving those facts. Demanding real proof of assignment — not a declaration reciting it — is frequently the pivot point of these cases.

The amount is wrong — or the person is

Plaintiffs must prove the balance, not just assert it. Compare the demand against your statements: post-charge-off interest the contract does not authorize, unexplained fees, payments never credited, and duplicated charges are all common. An inflated demand is both a defense on damages and potential affirmative ammunition, because materially misstating the amount of a consumer debt by a debt collector violates the FDCPA, 15 U.S.C. § 1692e, and may violate the Rosenthal Act, Civil Code § 1788.17. And if the account was opened by a fraudster — or the plaintiff simply sued the wrong person with a similar name — say so in your answer and make the plaintiff prove account origination. If you provide a police report and the required written identity-theft statement, which may be an FTC identity-theft affidavit, Civil Code § 1788.18 requires the collector to cease collection while reviewing the claim and permits collection to resume only after a good-faith determination that the information does not establish identity theft.

Procedural problems and counterclaims

  • Defective service. A judgment built on improper service can be attacked, but do not count on this alone — respond anyway.
  • Evidence gaps. Account statements must be properly authenticated and satisfy an applicable hearsay exception; cardmember agreements also must be authenticated. Debt buyers sometimes lack a qualified witness or declaration establishing the foundation for the original creditor's records.
  • Pleading defects. Debt buyer complaints missing § 1788.58's required allegations are vulnerable to challenge at the outset.

Collection misconduct before or during the suit — false threats, inflated balances, contact after a cease demand, validation failures under 15 U.S.C. § 1692g — can support counterclaims under the FDCPA and Rosenthal Act, carrying statutory damages and attorney fees under § 1692k and Civil Code § 1788.30. A defendant with a documented counterclaim negotiates from a very different position. The validation process itself is often step one; our debt validation page explains how to put the collector's file to the test before and during litigation.

What to do this week

  1. Note your response deadline and the court where you were sued
  2. Gather statements, payment records, and every collection letter
  3. Check the last-payment date against the four-year statute
  4. Identify the plaintiff: original creditor or debt buyer?
  5. Get the case evaluated before you call the plaintiff's law firm — unrepresented phone negotiations can produce admissions or lead to payments that affect your defenses

Many credit card suits settle for a fraction of the demand, or fall apart entirely, once a defendant appears and insists on proof. Experienced civil litigation counsel can tell you quickly which category your case is in.
