Thanks for the replies. I did some search on the net and found this. I am protected correct since I am from GA.
If You Negotiated a Settlement for Less Than You Owed, Can the Creditor Sue You For the Balance?
Yes! You need to read the following information carefully.
Some collection agencies will agree to settle with you for far less than you owe and then turn around and hire another collection agency to collect the difference. However, in many states this is illegal. Once a creditor deposits or cashes your check, even if they strikes out the words "payment in full" and writes "I don't agree" on the check, they can't come after you for the balance. The states in which this law is enforced:
Arkansas
Colorado
Connecticut
Georgia
Kansas
Louisiana
Maine
Michigan
Nebraska
New Jersey
North Carolina
Oregon
Pennsylvania
Texas
Utah
Vermont
Virginia
Washington
Wyoming
