A co-owner is seeking to register a relinquishment deed for ancestral property in Maharashtra, where their brother is transferring rights. The property is on a leasehold plot that has expired but is eligible for conversion to freehold under a 2018 government resolution. The sub-registrar is refusing registration due to missing 7/12 extract or property card. Experts advise converting the plot to freehold, obtaining a legal heirship certificate, mutating revenue records, and then executing a registered release deed for legal validity.
