Online I found this cool letter that may actual work to remove PAID collection accounts. This letter was used after contacting the collection agency previously about removing the account.
A good faith letter can be used to ask a collection agency/creditor to remove negative information off of your credit report. This letter somewhat asks the creditor to remove the negative item because at that time in your life you were irresponsible and now you have a record of paying on time. That is probably the easiest way to sum up this letter. This letter will not work for everyone, if you are behind on your bills a good faith letter would not be useful to you.
