You know, after a handful of years of dealing with credit matters and a year of Business Law classes under my belt, I got a pretty good idea of what the difference between an assignment and sale, so thanks. Just an FYI, the "ownership" part is what matters. An assignment transfers rights, not ownership. A sale transfers both.An "assignment" is the transfer of contractual rights to another. If a debt is said to be "sold", what they are selling is the right to collect the debt. Aka, assignment.
That said, I'll wait to see if this OP comes back and re-visits the thread.
