subpoena for chargeoff invoice

No, I don't think that you can check the price at which Unifund purchased your debt from JP Morgan. All that you can do is to send a debt validation letter to Unifund and on getting proper debt validation, you should negotiate with Unifund for a discount on the outstanding debt amount. Mostly, the CAs agencies agree to settle the debt to 40 to 50% of the outstanding debt amount.

Thank you. I've already offered 50% of balance, but they turned it down because of the default judgement. If the judge reopens my case on 3/25, I should be able to renegotiate. Anyway, thanks.

So a default was already entered? Did you not show up in court? Were you served properly? More details please.

Because JDB's buy up huge portfolio's at a time (thousands of accounts) at auction, there really would no feasible way for them to put an actual dollar amount on how much they paid for your individual account.
