Does my land have to be in my own name for PM-Kisan, what if it is in joint family name?

PM-Kisan does not strictly require the land to be solely in one person's name. The scheme is for landholding farmer families, and jointly held land can qualify, but the benefit is given per eligible family and per registered beneficiary, not multiplied freely on the same land. Each adult co owner who is a separate family (husband, wife and minor children being one family) can in principle register based on their share in the jointly held land, provided their name appears in the land record and they are not in any excluded category. So if you, your father and your brothers are each separate families and each of your names is in the joint record, each can register on the basis of being a recorded co owner, subject to verification and the rule that the same family does not get multiple benefits. The key practical requirement is that your name must appear in the official land record that the verification uses for land seeding. If the record only shows your father, then only he can be seeded until the land is partitioned or mutated to include your names. To avoid disputes, families usually either get the land formally partitioned and mutated so each share is clear, or coordinate so co owners register correctly. Confirm the exact treatment for your state and your record with the block agriculture office or revenue officer, because land record systems differ, and rely on the official pmkisan.gov.in rules and your local agriculture office for the final decision.
