How to Check an FMB Sketch in Kerala — Complete Guide 2026

The FMB Sketch, or Field Measurement Book, is the Survey Department's official record of a plot's exact boundaries, dimensions, and neighbouring parcels in Kerala. The FMB area must match the sale deed area exactly any gap is a problem that needs fixing before purchase. This guide covers what the sketch contains, how to get it, and what mismatches actually mean.

What is an FMB Sketch in Kerala land records?

Definition

The FMB Sketch, short for Field Measurement Book Sketch, is an official document prepared by the Survey Department of Kerala that records the precise boundaries, dimensions, and surrounding parcels of a specific land plot. It is maintained under the Kerala Survey and Boundaries Act and forms part of the cadastral records held at the Taluk Survey Office.

Every survey number in Kerala has an FMB. Think of it as the government's own ground-truth map for your parcel: drawn at a scale of 1:1000 or 1:2000, it shows G-lines (the base measurement lines), F-lines (actual field boundaries), subdivision lines, ladders showing offset distances, extension lines where adjacent plots intersect, and the survey numbers of every neighbouring field. When you read an FMB correctly, you can see exactly what's yours, what's your neighbour's, and where roads or government land borders the plot. Nothing else in the Kerala document set gives you that physical picture.

The FMB sketch does not prove ownership that's the sale deed's job. What it does is confirm whether the physical land being sold matches what's on paper. This is why the Kerala Survey Department requires that the FMB area match the deed area exactly. Old FMB records are based on manual measurements from the original cadastral survey, which can be decades old. Kerala's ongoing Digital Resurvey Mission is correcting many of these under KLIM, and resurvey data is now progressively available on Ente Bhoomi. If a resurvey has been completed for your village, that record takes precedence over the old FMB for boundary purposes.

State-specific note: In Kerala, the FMB area and the sale deed area must match exactly. A shortfall in the FMB means land is missing from what you're paying for. An excess can create encroachment claims. Neither is safe to ignore.

How to Get FMB Sketch in Kerala

FMB sketches are available online through [erekha.kerala.gov.in](http://erekha.kerala.gov.in) and the Ente Bhoomi portal, or in person at the Taluk Survey Office. Have your district, taluk, village, block number, and survey number ready before starting either method.

Online method (recommended)

Go to the E-Rekha portal Visit [erekha

kerala.gov.in](http://erekha.kerala.gov.in) . This is Kerala's official land records portal under the Kerala Land Information Mission (KLIM). If you haven't registered, create a free account with your name, mobile number, and email.

Navigate to FMB data From the main page, click on "Record Catalogue," then select "List of FMB Data Online

" District-level FMB data appears in a table. Click "Show Villages and Block" for your district, then "Show Survey Numbers" to locate the specific village and block you need.

Enter your survey details and preview Select the FMB option under the Map category

Enter your district, taluk, village, block number, and sheet number, then click Submit. The portal displays a preview of the FMB sketch for that survey number.

If the village isn't showing FMB data, the area may be pending digitisation. Check Ente Bhoomi at [entebhoomi.kerala.gov.in](http://entebhoomi.kerala.gov.in) for resurvey records, which may already be available even if the old FMB isn't.

Pay and download Proceed to checkout

For FMB resurvey files, the fee is Rs. 750 including taxes, paid via e Treasury using UPI, net banking, or card. Once payment is confirmed, download the sketch in PDF format.

3. What does an FMB Sketch contain in Kerala?

Every FMB sketch in Kerala carries a specific set of technical and identification fields that buyers need to read, not just collect.

Field	What it means	What to check
Jurisdiction Details	District, Taluk, Village	Identifies the revenue jurisdiction of the parcel
Survey Identification	Survey number and subdivision	Unique cadastral identifier of the land parcel
Parcel Extent	Area in ares or cents	Measured land area as per survey records
G-lines & F-lines	Base lines and field boundary lines	Defines measured and actual physical boundaries
Subdivision Details	Subdivision lines and ladder measurements	Shows internal divisions and offset data
Adjacent Survey Numbers	Neighbouring field survey numbers	Identifies surrounding parcels

Good sign: A clean FMB shows the correct survey and subdivision number, an extent matching the sale deed, clear boundary lines with legible measurements, and consistent neighbouring survey numbers.

### Common Issues With the FMB Sketch in Kerala

Every FMB sketch in Kerala carries a specific set of technical and identification fields that buyers need to read, not just collect.

FMB area doesn't match the sale deed

This is the most significant and most common problem. The deed says 40 cents; the FMB shows 35 cents. Or the reverse. Either way, the registered area and the surveyed area don't agree, and buying under those conditions transfers a legal dispute along with the land.

Fix: Do not proceed until a licensed surveyor physically measures the plot and the discrepancy is explained in writing. If the FMB is wrong, apply for correction at the Taluk Survey Office. If the deed is wrong, the previous transaction may need to be reviewed by a property lawyer.

Old FMB not updated after subdivision

A survey number was subdivided years ago, but the FMB still shows the original undivided parcel. The seller's portion isn't individually recorded, so the sketch doesn't match what's actually being sold.

Fix: Ask for the mutation sketch or subdivision sketch that shows the specific portion. If resurvey data is available for the village on Ente Bhoomi, check that too resurvey records may already reflect the subdivision more accurately.

Neighbouring field boundary dispute visible on FMB

The extension lines or boundary markings on the FMB overlap with an adjacent survey number, or the neighbouring field's survey number recorded on the FMB doesn't match what the neighbour's documents show. These are early signals of an encroachment dispute.

Fix: Before signing anything, physically walk the boundaries with a licensed surveyor and confirm that existing physical features (walls, fences, paths) match the FMB lines. If they don't, get a legal opinion before proceeding.

Village not yet covered by digital resurvey

The village is still on old manual FMB records, which may contain measurement inaccuracies accumulated over decades. Resurvey data is available for 813 villages in Kerala as of the last KLIM update, but coverage is incomplete.

Fix: Check the Ente Bhoomi portal to see if resurvey data is available for the village. If not, treat the old FMB figures as approximate and commission a physical survey before finalising the purchase.

G line errors in the sketch

The base measurement line (G-line) has been recorded with an error, which distorts all subsequent boundary and offset calculations. This is a technical defect but it has real consequences for boundary fixing on the ground.

Fix: Engage a Head Surveyor (the OLC process in Kerala routes boundary disputes through Head Surveyors) to identify whether a G-line error exists and to initiate a correction application at the survey office.

FMB sketch shows road or government land within the plot

Part of the area recorded in the survey number is poramboke (government land), a public road, or a water body. The seller may not have disclosed this, or may not have known. You'd be paying for area you can't privately own or build on.

Fix: Cross check the FMB classification against Thandaper records and the BhuNaksha map at [emaps.kerala.gov.in](http://emaps.kerala.gov.in) . Confirm the exact privately ownable extent before agreeing on a price.

### Why the FMB Sketch Matters for Land Buyers in Kerala

No other document in Kerala's land record system tells you what the physical land actually looks like on the ground only the FMB does that.

📋

The only document that shows you what you're actually buying The sale deed describes land in words and numbers

The FMB sketch draws it. Sellers routinely quote deed area; the FMB is where you find out if that area is real. Skipping the FMB is buying land on trust alone.

⚠

FMB area must match deed area exactly This is not a guideline -it's the boundary verification standard in Kerala

A mismatch is an unresolved legal risk. Courts have referenced FMB records in boundary and ownership disputes precisely because this is the government's surveyed measurement of the land. An unexplained mismatch leaves the buyer exposed to claims from the state, from neighbours, or from previous owners.

🏦

Required for building approvals and home loans The FMB sketch is required to obtain a building plan approval in Kerala

Banks processing home loans also ask for it as part of title and boundary verification. A missing or mismatched FMB stalls both processes.

🔍

Kerala-specific: resurvey records are superseding old FMBs This is something Kerala-specific buyers must know

Under the Digital Resurvey Mission, resurvey data for completed villages takes precedence over older manual FMB records for boundary purposes. If your village has been resurveyed, the old FMB numbers may no longer be authoritative. Check Ente Bhoomi for the current resurvey status of the village before relying on old FMB figures.

Red flag: If the seller shows a deed area that's higher than the FMB area, or cannot produce an FMB sketch at all, stop. Do not pay an advance. The difference between what's on paper and what's on the ground is your financial risk, not the seller's.

Frequently Asked Questions

What is an FMB Sketch in Kerala land records and why does it matter?

The FMB Sketch is the Survey Department's official record of a plot's exact boundaries, dimensions, and neighbouring survey numbers. It's the only document in Kerala's land record system that physically maps what you're buying. The FMB area must match the sale deed area exactly before any purchase.

How do I download an FMB Sketch in Kerala online?

Go to [erekha.kerala.gov.in](http://erekha.kerala.gov.in) , register for free, click Record Catalogue, then List of FMB Data Online. Select your district, taluk, village, block, and survey number. Preview the sketch and pay the applicable fee via e-Treasury to download the PDF. Resurvey data is also available on [entebhoomi.kerala.gov.in](http://entebhoomi.kerala.gov.in) .

What happens if the FMB area doesn't match the sale deed area in Kerala?

It's a serious problem, not a paperwork gap. A mismatch means either the FMB record has an error or the deed overstates the area. Either way, buying under those conditions transfers the discrepancy to you. Require the seller to get the error corrected at the Taluk Survey Office before you sign anything.

Is the FMB Sketch required for property registration in Kerala?

Not mandatory for registration itself, but practically essential. Banks require it for home loan approval, and the local body requires it for building plan approval. More importantly, without verifying the FMB, you have no way to confirm that the deed area matches what's physically on the ground.

Can an FMB Sketch be used as evidence in court in Kerala?

Yes. The FMB is an official government document and is admissible as evidence in land boundary disputes in Kerala courts. Survey Department personnel, particularly Head Surveyors, are involved in OLC (Original Land Complaint) proceedings where FMB records are central to adjudicating boundary claims.

How is the old FMB different from the resurvey FMB in Kerala?

Old FMB records come from the original manual cadastral survey, which may be decades old and contain measurement inaccuracies. Resurvey FMB records are produced under Kerala's Digital Resurvey Mission using modern technology and correct historical errors. Where resurvey is complete, those records take precedence. Check Ente Bhoomi for your village's status.

Is the FMB Sketch required for a home loan in Kerala?

Most banks and housing finance companies ask for the FMB sketch as part of their legal due diligence for home loans in Kerala. It confirms that boundaries are clear, the area matches the deed, and no encroachments or government land issues exist. A missing or mismatched FMB can delay or block loan sanction.

How do I correct an error in the FMB Sketch in Kerala?

Errors cannot be corrected through the online portal. Visit the Taluk Survey Office and file an application with supporting documents, including the sale deed, tax receipts, and any surveyor's report. A court order may be required for significant corrections. The process routes through the survey office or Taluk mapping office.
