Yes. You have to tell the court which property he is holding. The court will direct him to produce the property details, as they will be in his exclusive possession and none except he has the custody of the papers related to property. You have to tell the court also where he is working. The court will, at the instance of your advocate, call for the records of the salary register from where he is working. You have to explain the coourt in your petition that how much amount that can be drawn by renting out, if it is a house or how much it can yield, if it is an agricultural field. Just by mere his saying that he is not earning and the property does not derive any amount will not be believed by the court.
