Compensation For Land Acquisition By BDA

My father bought a 20 gunta (1/2 Acre) of land in a Village in North Bangalore that is notified by BDA for Shivaram Karanth Layout. A surveyor came recently to survey the area. I need to submit my property documents to ensure I get adequate compensation. Can you refer me to a lawyer with working relationship at BDA to negotiate compensation and process my claim?
