ยง 1328. Discharge of attachment. 1. A defendant whose property or debt has been levied upon may move, upon notice to the claiming authority and the claiming agent, for any order discharging the attachment as to all or part of the property or debt upon payment of the claiming agent's fees and expenses, if any.
