FMB Sketch in Tamil Nadu: How to Get, View & Download Online


Buying land is a major financial decision, especially in a fast-growing market like Tamil Nadu. Before purchasing a plot, buyers usually check the title deed, patta, encumbrance certificate, approved layout plan, and other property documents. One important record that should not be overlooked is the Field Measurement Book sketch, commonly called the FMB sketch.
An FMB sketch helps you understand the exact location, shape, measurements, boundaries, and subdivision details of a land parcel. It can also help identify discrepancies between the documents and the land available on the ground. This guide explains the meaning, features, uses, and online process for obtaining an FMB sketch in Tamil Nadu.
What Is an FMB Sketch?
FMB stands for Field Measurement Book. In Tamil Nadu, the Field Measurement Book contains individual sketches of survey fields within a village. Each sketch generally relates to a particular survey number or subdivision and records the field’s boundaries, measurements, shape, and connection with neighbouring parcels.
The Tamil Nadu Survey and Settlement Department describes the FMB as a collection of field measurement sketches for individual fields. These records are useful for identifying the location of a survey field and resolving boundary-related issues.
In everyday property transactions, the terms “FMB sketch” and “Field Measurement Sketch” are often used interchangeably. The Tamil Nadu Government’s online land-record portal also refers to the service as “FMB Sketch” and “Field Measurement Sketch” or FMS. The portal provides FMS copies free of cost through its e-services.
For a buyer looking for FMB sketch for land in Tamil Nadu, this document offers a visual representation of the property as recorded in government survey records. However, it should not be treated as independent proof of ownership. Ownership must be verified through documents such as the sale deed, parent documents, patta, and encumbrance certificate.

What Does an FMB Sketch Show?
An FMB sketch is usually prepared using survey measurements and is drawn to a specific scale. Depending on the property and the available record, it may contain the following details:
- Survey number and subdivision number.
- Shape and layout of the land parcel.
- Length of the boundaries.
- Measurements of individual sides.
- Adjacent survey numbers or neighbouring properties.
- Directional references, such as north, south, east, and west.
- Existing pathways, roads, channels, water bodies, or government land, where recorded.
- Field boundary lines and survey reference marks.
- Details that help relate the sketch to nearby parcels.
The sketch may use traditional measurement units or metric measurements, depending on when it was prepared and how the records were digitised. If the measurements are difficult to understand, a licensed surveyor can help interpret the sketch and compare it with the physical boundaries.
For example, assume a sale deed describes a rectangular plot, but the FMB sketch shows an irregular shape or a different access pathway. This difference should be investigated before the transaction proceeds. A mismatch does not automatically mean that the property is defective, but it may indicate a subdivision, resurvey, access, or boundary issue that requires clarification.

Key Features of an FMB Sketch
- Survey Level Information
An FMB sketch relates to a specific survey number or subdivision. This makes it more precise than a general village map. It helps identify the position of an individual parcel within a larger survey field.
- Boundary And Measurement Details
The sketch records the dimensions and boundary lines of the field. These details can be compared with the sale deed, layout plan, patta, and measurements taken at the site.
- Neighbouring Land References
Neighbouring survey numbers shown in the sketch can help establish how the property is situated in relation to surrounding parcels. This is particularly useful when checking whether the physical location matches the description in the title documents.
- Digital Accessibility
The Tamil Nadu Government provides online access to FMB-related land records for rural and Natham areas. The e-services portal includes separate services for viewing Patta/Chitta/FMB, obtaining an FMB sketch, and accessing TSLR records for urban areas.
- Support For Boundary Verification
An FMB sketch can assist with identifying possible encroachments, boundary overlaps, or incorrect fencing. It is especially useful when a buyer wants to verify whether the actual plot corresponds with the official survey record.
- Reference For Survey Applications
If a boundary dispute or measurement problem arises, the FMB sketch may be referred to when applying for an official survey or F-line measurement through the appropriate revenue authorities. It is supporting evidence, but the relevant authority may require additional documents and a field inspection.

How to View FMB Sketch Online in Tamil Nadu
If you want to view FMB sketch online in Tamil Nadu, use the official Tamil Nadu land-record e-services portal. Keep the property’s district, taluk, village, survey number, and subdivision number ready before beginning.
The general process is as follows:
- Visit the Tamil Nadu Government’s Land Records e-Services portal.
- Select the option for “FMB Sketch – Rural/Natham” or the relevant Patta/FMB service.
- Choose the district and taluk.
- Select the village or revenue village associated with the property.
- Enter the survey number.
- Enter the subdivision number, if applicable.
- Submit the details and review the available record.
- View the digital sketch and download or print it for reference.
The portal states that users should have the survey number and subdivision number, patta number, or owner name available to obtain land-related information.
The exact screen layout and menu names may change when the government updates the portal. If the sketch is not displayed, check whether the survey number has been entered correctly or whether the land falls under an urban record system. Urban properties may be associated with Town Survey Land Records, or TSLR, rather than a rural or Natham FMB record.

FMB Sketch Download Tamil Nadu: Important Points
The FMB sketch download in Tamil Nadu process is generally available online without visiting a revenue office, provided the relevant record has been digitised and is available in the portal. The government portal states that copies of Field Measurement Sketches can be downloaded free of cost.
However, buyers should keep the following points in mind:
- The online record may be intended for viewing and reference.
- The document may not replace a certified copy required by a court, bank, authority, or legal professional.
- Names and other extracts may appear in Tamil Unicode font.
- Do not use the browser’s automatic translation option while viewing official extracts, as the portal warns that translation may affect names and details.
- Save a copy of the downloaded record along with the date on which it was accessed.

What About an Old FMB Sketch?
An old FMB sketch in Tamil Nadu record may be useful when tracing the history of a survey number, subdivision, or boundary. Older sketches can become relevant when land has undergone subdivision, reclassification, resurvey, road formation, or changes in ownership.
For instance, a parent survey number may have been divided into several new subdivisions. The current FMB sketch may show the latest subdivision, while an older sketch may help explain how the original land was divided. This can be valuable during title verification.
Do not rely on an old sketch alone. Compare it with:
- Current patta and Chitta details.
- Sale deeds and parent documents.
- Encumbrance certificate.
- A-Register extract.
- Approved layout or planning permission.
- Current FMB or FMS record.
- Physical measurements taken at the site.
Where there is a difference between old and current records, obtain professional legal and surveying advice before making a payment or signing an agreement.
