Can I claim subsidy on land that is in my father's or joint name?

Subsidy is normally given to the person whose name appears on the land record, so land in your late father's name is a frequent reason applications stall. The clean solution is to complete mutation, the transfer of the record into the legal heirs names, after which any one of you can apply on your share. If mutation is still pending, many schemes accept a joint application or one applicant with a written no objection from the other co owners, but the subsidy still pays to the applicant whose details are submitted, so decide among the family who applies. Applying on a record that names a deceased person without any heir documentation usually fails verification. So your first step is to start the mutation at the tehsil or revenue office, and in the meantime ask your block agriculture office whether your state allows an heir to apply with a legal heir certificate and co owner NOC for the scheme you want. Rules vary by state and by scheme, so confirm the accepted proof of land ownership on your state portal or with the office before applying.
