Registry

It's all dependents upon the State Government Stamps and Revenue Department Rules. There is an option to register the property as per 1979 rate but, you should have proper support documents like atleast a Sale Agreement on a Stamp Paper of 1979 or prior to 1979. Transfer of Funds and Possession of the Property. You can approach the respective Registrar Office and know the right documents as required n submit the same.

Getting a fresh sale deed as on date, mentioning of an oral agreement etc., of the past may solve the issue, but you have to pay the stamp fee as per existing market rate.
