You're looking to buy a plot with a Gramakantam certificate issued in November 2020, following a sale deed from July 2020. Gramakantam land is typically village common land, but recent government initiatives in Telangana and Andhra Pradesh are granting title deeds to occupants. While the certificate indicates the plot falls under Gramakantam, it's crucial to obtain a proper legal opinion before proceeding with the purchase to ensure clear ownership and avoid potential issues.
