When you need it
A photostat or printed copy of the aks shajra — the existing revenue map of the village or estate, showing every khasra number and its recorded boundary — for a specific field or for the whole village. Buyers and lenders ask for it in title due diligence, it is used to check that a field's shape and neighbours on paper match what is on the ground, and it goes into building-plan, change-of-land-use and boundary-dispute papers.
This is a request for a COPY of the map as it already exists, not the preparation of a new one. Where part of a khasra has been sold, partitioned or mutated and you need a fresh sub-division sketch of the resulting piece, that is a tatima shajra — a different document prepared by the Patwari for that specific purpose — and is not what this application obtains.
Punjab: apply to the Halqa Patwari through the Kanungo and the Tehsildar or Naib-Tehsildar of the tehsil, or request the copy at the Fard Kendra of that tehsil or through jamabandi.punjab.gov.in, which carries the current shajra for most districts.
Chandigarh has no aks shajra for a sector property held from the Estate Office, whose own site plan and allotment file serve that purpose instead; a village map exists only for the Union Territory's retained revenue estates — Manimajra, the lal dora and phirni villages, and the villages never brought onto the Estate Office scheme — kept by the Patwari of that estate through the Naib-Tehsildar, Chandigarh.
A shajra shows numbers and recorded areas as last settled or revised on paper. It does not itself fix a boundary on the ground — that is a separate demarcation (nishandehi) proceeding — and it does not change the record of rights or confer title.
