Three documents, one survey number. Patta proves ownership, chitta/adangal is the yearly account, and the FMB is the survey sketch. Here is when each one matters.
The patta names the owner, survey number, extent, and kist. It is the document lenders and authorities treat as proof of who holds the land, and it is the one transferred by mutation when a sale or inheritance takes place.
Chitta (or adangal) is the yearly village account: who holds and cultivates each survey number, the extent, crop, and tax paid. It proves the land is recorded and up to date, not ownership in itself.
The FMB is the geometric record — the shape and measurements of the survey number. Ownership documents tell you whose it is; the FMB tells you where it is and how big.
Banks generally ask patta + chitta + FMB. Courts and boundary cases lean on the FMB. For a plot across several survey numbers you'll also need the combined FMB sketch.
A common family survey number shared by several heirs needs one map everyone can read. We join the shared FMB sheets and mark each heir's share on a single partition map — a clear, neutral document for the whole family and for official use.
Common questions about Combined FMB Sketch services across Tamil Nadu.
No — chitta/adangal is the annual account; ownership is the patta together with the sale deed.
Banks and approvals often ask for all three: patta, chitta, and FMB, since they prove different facts.
