You can inform your advocate and make yourself available before court on the date of hearing to witness the proceedings in person.

Dear Sir,

You can appear in person by taking back the vakalat/power given to your advocate.  You just ask your advocate to file retirement memo and then file your memo of appearance to conduct the case as “ Party in person”. You can see how and how long the proceedings will take place before the courts.

Dear Sir,

My answers are as follows:

1. I can appear for the court proceedings.

Ans: Yes, you can approach but cannot submit unless your advocate is retired from case.

2. The lawyer can run the entire proceedings for me.

Ans: If you have faith in your advocate then he can run your case provided sometimes the Court may ask you to be present in person.

3. I'd like to know what procedure is followed in the court after I/we submit the counter petition. I mean, if the party's presence is optional, how will the advocates argue. How long will the appeal procedure take time to complete.

Ans: Only arguments are to be advanced by both the advocates and time taken may be between 12-24 months depending upon the pendency of cases.

4. I'd like to visit the court and see and involve in the proceedings myself. Is this possible?

Ans: Yes, you can.

5. Does it mean that during the trial of the revision/appeal case, I can only be a spectator of the proceedings unless the court allows me to talk? And to attend, I'll have to get the entry pass from the High court?

Ans: Yes, you will be a spectator unless you wish to be Party in Person.

6. I've engaged an advocate already. I'm not appearing as P-I-P.

Ans: You may ask your advocate to retire from the case and conduct the case by yourself because it will be more effective.
