Can I get legal remedy against a hall owner who has no occupancy?
You need to check with local jurisdiction for specifics. But one suggestion to look into, is posting no parking signs that specify they will be towed. There are Tow shops who specialize in keeping no parking sites clear of cars. They do not charge you anything, but rather make all of their money towing the car and impounding the vehicle, until all of the fees are paid. A few weddings like that and the owner of the hall will beg you to accept money for the use of the land or will make other provisions for his guests.
