States that permit motions to vacate a judgment state the basis as a request for relief by the consumer, not the judment creditor.
You can file your own motion to vacate IF your state statute permits vacuture as a form of relied based on satisfaction of the judgment.
It does not hurt to have the judgment creditor file a motion of support for your requested vacature, but they are not the primary in such a motion.
I have seen numerous posts on other legal web sites from attorneys who state that they consider it a conflict of interest for them to file motions on behalf of the adversary of their client, and they do not ever do so.
