Katha Extract … Also court decided the property division prior to my current owner in year 1980’s that court order Xerox copy I have it with court seal. My owner is owning this property from 25 years. When I applied the copy in civil court bangalore, they are saying since it is older than 1990 year the court copies are destroyed.
