Can the Clerk of Courts in one state be used to notify expungement forms for another state?

The short answer is yes. Getting a document notarized only has to be done before a certified notary, regardless of the state or jurisdiction. However, pertaining to expungements, make sure that all the rest of your documents are from the locations and courts required per your State's expungement rules. Often times for expungements you have to provide finger prints and court records and supply that information to the court/state in which you were sentenced.
