I want to take off a collection that is posted on my credit report. I was sent to collection from a former college where I was taking some classes. I thought I had paid it but I have no proof so I paid it again but now I realize that the collection on my credit report is driving my credit score down that I can't take advantage of the mortgage rates currently. So I want to file a motion to vacate in hopes that the creditor which has already been paid won't show up and I win by default. How do I file a motion to vacate in NY and do I need a lawyer to do it? Thank you in advance for any help.
