If your father's lease deed for industrial land is being cancelled due to factory inactivity, his rights are significantly impacted. Leasehold land cannot be sold like freehold property, and attempting to sell it could be a prosecutable offence. While the lease is active, transfer might be possible with authority approval, but selling after cancellation is unlikely. It's crucial to review the lease agreement and notice carefully, and consult a local legal expert to understand your father's specific situation and options.
