Section 143 of land

Mutation (in Hindi Dakhil-Kharij) is the recording of a transfer of title of a property from one person to another in the revenue records. Registration is one part and mutation is second. After registry, mutation is needed. Mutation is a Must. It is because of mutation that your name (as the owner of house) comes in Nagar Nigam Records. Compensation is given to farmers based on the mutation records and not on the registry records. If person ‘A’ has registry in his name of a piece of land AND for the same land mutation is in the name of person ‘B’, then Government will give compensation to person ‘B’ and not ‘A’.

But my question is Still unanswered? In my Case The Second party in a Real State Firm not a single person. According to the firm they are selling the plots to the customers after making the land under "SECTION 143". So "After Section 143" DAKHIL KHARIZ is REQUIRED in my Case or not. Please suggest me .Thanks in advance
