Name in municipal record but don't know khasra aur khatauni number

Personally visit to the concerned Municipal surveyor section, and they have maps with them and they can provide that information.   You can use RTI for seeking that informationn.  Search website of the authority to locate Public Information officer, format of application and mode of remitting RTI fees of Rs.10 and seek information as follows:

Subject on which information is sought:  House No..............Ward No....................address.

Documents enclosed: Copies of sale deed, copies of latest tax paid receipt.

Information solicited:

1)Please provide the Khasra Number/Khautani of the above mentioned building as per Municipal maps.

You can also inquire with neighbours on all four sides for such number as their documents may state such number.  Normally when there is mutation, title deed in your name over 18 years, no legal advisor insists for such number.  You can also contact any advocate and get inspection at Register office, and he can get the number through inspection of records.

Thanks a lot, that really helped.
