A mortgagee who fails to file a satisfaction within thirty days of receiving a written request shall be subject to reasonable damages and a penalty of five hundred dollars plus reasonable attorney fees incurred by the aggrieved party, to be recovered in an action for the satisfaction by the party aggrieved.
