Also called: Dakhil kharij, Namantaran, Intkal, Ferfar (Maharashtra)
Updating the municipal record to your name after a purchase. Not the same as registration, and easy to forget.
How it works and what to check
After a sale, inheritance or gift, the revenue office (for land) or the municipal body (for urban property) updates its record to the new owner. That update is mutation. It is how future tax demands, utility connections and land records come to you.
Registration of the sale deed does not mutate the record by itself in most places, though some states now trigger mutation from registration automatically. In Bihar and Uttar Pradesh the process is called dakhil kharij; in Maharashtra a mutation entry (ferfar) is made in the record of rights.
Apply soon after registration with the deed, tax receipts and identity documents, and keep the mutation order.
Common questions
Is mutation the same as registration?
No. Registration of the deed transfers ownership; mutation updates the government's revenue or tax record to show it. You usually need both.
Does mutation prove title?
Courts have repeatedly held that a mutation entry is for revenue and fiscal purposes and does not by itself confer title. The registered deed does.
