but in procedure of DRT it is written that a party can produce itself by way of appointing an agent
agent means a person duly authorized by a party to present its application or reply on its behalf before the DRT
I will always advise to appoint advocate. One may be aware about the procedure but persons cannot have legal expertise. Just to save some thousands of rupess parties may ruine their properties. It is upto parties to have expert persons or just a procedure aware crook.
