What is a FMB (Field Measurement Book) sketch?

A Field Measurement Book (FMB) sketch is an official cadastral map maintained by the state survey department showing the precise boundary dimensions, shape, and area of each survey number and sub-division in a revenue village.

What an FMB Sketch Shows

• Precise measurements of each side of the plot (in chains or metres).
• Boundary lines between the plot and adjacent survey numbers.
• Area of the plot (calculated from field measurements).

Importance in Land Transactions

• Boundary verification prevents encroachment disputes with neighbours.
• Matching dimensions in the sale deed with FMB dimensions.
• Required for layout approvals and NA conversion applications.

The FMB sketch is the official boundary map of your land essential for verifying that the plot described in your sale deed matches the actual dimensions on the ground. Always obtain a certified FMB copy and compare it with a fresh physical survey measurement before purchasing any land to prevent boundary and area discrepancies.
