what is the process for getting my record expunged in arkansas for a first time misdomeaner offense of theft of property?

You must first complete the sentence you were given including any probation (most of the time). After that, you need to file a petition to expunge your record; serve the prosecuter with your petition; ask that the petition be set for a hearing and appear before the presiding judge for a ruling on your petition. That is a pretty simplified description of how you go about getting your record sealed.
