Legal Question in Credit and Debt Law in California

Not exactly. You must conduct discovery to obtain sworn responses that do not produce any proof of the debt. Then you must file a motion for summary judgment. Or you can wait until trial, see if they have the evidence, and then if they don't move for "nosuit."

If this applies to you, consult an attorney before filing a response with the court. Your original contract with the creditor provides that they will pay your attorney fees if you win, so why wouldn't you?

You may have a claim against the collection agency under the Fair Debt Collections Act. We would have to review your correspondence to see if you have one. Other than any formal violation, you would have to obtain Plaintiff's testimony under oath that it does not have the documentation and then file a Motion for Summary Judgment.
