 File a formal memo or application with the civil court stating that you intend to represent yourself in person. Unlike a lawyer, you do not need to file a vakalatnama.

For high court matters, you may need to file a formal application seeking permission, and the court may scrutinize your ability to argue your case effectively.

If you cannot afford an advocate, you can seek free legal assistance under Article 39A of the Constitution. You can apply for this service through the District Legal Services Authority
