What is the name of your state (only U.S. law)? Wyoming. In March of 2015 I went to the hospital. Now I'm in collections. We went to court in December of 2015 and agreed upon a payment. Now the debt collectors are calling me again saying I'm not paying enough and that I need to send them receipts of my pay stubs and all my bills to determine if they can raise my monthly payment. Is this legal? Or since we already went to court can they not demand my receipts?
