The RTC (Record of Rights, Tenancy and Crops) is also known as Pahani. It is an important land record in Karnataka that is issued to the existing landowner. The documents include the owner details and all the land-related details such as: Information about the landowner.
This land record management system was introduced in 2000. It uses advanced online technology for land management under which all the manual Record of Rights (RTCs) which are examined at the time of data entry were digitized and made available to the citizen through Kiosk Centres. All the ownership or any other changes in the Record of Rights (RTCs) are executed through mutation as per the Karnataka Land Revenue (KLR) Act using the Land Records database.
Since the records are not updated in their data base, you might have been instructed to get the RTC transferred to your name.
You may apply for transfer of records in the RTC to your name if that is insisted as an essential document to consider the taxes to be paid to your name
