Brent is absolutely right. You register the foreign judgment in Nevada and then once Nevada accepts it, you record your Nevada judgment with the county recorder's office. Usually costs less than $25, depending on the number of pages involved. Hope this perspective helps!
You have to go through a process called "domesticating the judgment" in Nevada. Not terribly difficult to do...just filing out some forms, paying a filing fee, and sending notices. Once the judgment is accepted (domesticated in NV), then you can file a lien at the county recorders office.
