My question involves collection proceedings in the State of: Minnesota

If a collector and i agree on an amount to settle for and I paid said amount, what protection do I have that they would not sue me or re-sell the debt.

I am also willing to pay more if they agree to remove the judgements from my credit report but i would have to pay by credit card. I make enough money that Im confidant i wouldnt get in the same situation with this card, I just dont have a large lump sum like they want. If I pay them by credit card do I have any assurance they can't use my credit care and keep racking up charges?

Do I just get a letter from them? If so what should I make sure that it says? Would a letter hold up in court if they came back at me i n the future?

Thank you so much!
