A law firm representing a creditor serves a court summons on a debtor who claims the debt is a 'Identity Theft Matter'. The debtor mails a copy of his identity theft police report to the law firm/plaintiff. What is suppose to happen at this point?
If the law firm representing the creditor believes that you were the victim of identity theft and/or they believe that you can prove that in a court of law, then they should dismiss the case that they filed against you. But if they don't believe that you were the victim of identity theft and/or they don't believe that you can prove that in a court of law, then they should continue the case that they filed against you. (Personally, if I were them, I would not believe that you were the victim of identity theft nor that you can prove it in a court of law, based only on a copy of an "identity theft police report" that you sent me.)
Is the victim of identity theft expected to prove the debt is not his, or is the law firm/plaintiff expected to prove the debt IS HIS??
Generally speaking, the plaintiff would present their evidence that you obtained credit from the original creditor who sold the debt to them for collection. Then the defendant would present their evidence that they were the victim of identity theft and that they never obtained credit from the original creditor. It will be up to the court to determine who's evidence is more persuasive. (This isn't criminal court. The plaintiff doesn't have to present proof beyond a reasonable doubt. It's simply proof by a preponderance of the evidence.) For instance, as was already pointed out, if you can prove that the police charged someone else with a crime related to stealing your identity, then that would presumably go a long way to persuading the court that you didn't obtain credit from the original creditor in this case. On the other hand, if you don't have evidence that the police charged someone else in connection with stealing your identity, and the plaintiff can prove that the credit account was paid for using a bank account that was opened in your name and you never complained that the bank account was compromised in any way, then that might go a long way to persuading a court that you opened the credit account.
You get an attorney and/or you file an answer in court to the complaint that was filed against you in court. If you don't, then the plaintiff will probably get a default judgment against you. Once that happens it will be too late to try and claim that you shouldn't have been sued.
