No single extract should be treated as the entire legal history of a property. Match the survey number, subdivision, extent, boundaries, names and dates across available records.
A revenue record identifying the person or persons recorded for a parcel and related survey details. It is important evidence, but it is not by itself conclusive proof of title.
Patta number, survey and subdivision, extent, recorded names, transfer order and consistency with title deeds and other records.
A land-revenue record associated with ownership and land details. Availability and format depend on the relevant rural or urban record system and current portal.
Reference number, survey identity, recorded holder and whether the extract is current and verifiable through the official service.
A village account with key survey-level particulars, which may include classification, extent, assessment and pattadar-related entries.
Recorded classification, survey/subdivision, extent, land type and differences between old and current entries.
A village account traditionally associated with cultivation and crop details. Its content and role should be read in the context of the record and period concerned.
Relevant season or year, cultivation details, survey number and whether the entry is being incorrectly treated as a title deed.
A field sketch used to understand surveyed parcel geometry, measurements and subdivisions. It helps with boundary investigation; it does not alone establish ownership.
Correct village, survey and subdivision, adjoining parcels, scale/measurements and whether a licensed surveyor should inspect the ground.
Town Survey Land Register, used for relevant urban town-survey records. Urban records and rural village accounts are not always interchangeable.
Town, block, ward, town survey number, subdivision and corresponding urban sketch or related extracts.
A registration search covering transactions recorded in the relevant period and search scope. An EC does not reveal every possible legal, possession or title issue.
Correct property identifiers, search period, document numbers, names, link documents and possible unregistered claims or litigation.
Earlier registered instruments and supporting records help trace how the claimed title passed from one party to another.
Continuity of title, undivided shares, legal heirs, release/partition documents, court orders, powers of attorney and registration details.
LAND CLASSIFICATION
Read the exact wording in the relevant record. Similar-sounding labels can have different implications depending on the original settlement, the land's history, applicable law and later orders.
Traditionally associated with wet or irrigated agricultural land. The actual recorded classification and applicable land-use controls must be checked.
Traditionally associated with dry agricultural land. The label alone does not establish that residential or commercial development is permitted.
A term associated with rain-fed cultivation in relevant records. Confirm the exact classification in the village account and applicable rules.
A traditional village-residential land classification. The legal effect depends on the precise land, occupation, records and applicable court decisions.
A label that may appear in revenue records for land classified as natham poramboke. Do not infer ownership or eligibility for patta from the label alone.
Land recorded in relation to a tank or lake. Check original survey records, tank registers, boundaries and the relevant water resources authority's records.
Terms associated with ponds or small waterbodies in relevant local records. The precise classification and public use need confirmation.
Can refer to a channel, irrigation course or stream. Investigate historic flow paths, field sketches and department records before drawing conclusions.
Riverbanks, channels and associated land may be governed by specific public, environmental, flood-management and water-resource rules.
Road, cart-track or pathway entries may relate to public access or a recorded route. Confirm alignment, width and legal status on the ground and in records.
Land recorded for burial or cremation use. Do not treat it as ordinary saleable land without clear legal and official confirmation.
Entries may refer to common village uses. Check the specific register, local-body records, settlement orders and restrictions.
“Waste” or uncultivated entries can describe a revenue or land-use status. They do not automatically mean unowned, freely transferable or buildable land.
Local record labels vary. Forest, hill, assigned or specially regulated lands may be subject to separate statutes and department controls.
Urban TSLR entries should be read with the town-survey sketch, local planning records and the relevant urban revenue authority's records.
This is an educational list of commonly encountered terms, not a complete or authoritative statewide taxonomy. Spelling, usage and legal consequences can vary by record, district and historical context.
SPECIAL CHECK
Do not rely on a single online extract when a parcel is close to a lake, tank, channel, stream, flood path, road or common-use area.
HISTORY IN CONTEXT
Survey and settlement, revenue administration, land reforms, record updating and town planning developed through different legal and administrative tracks. The timeline below is a high-level orientation, not a substitute for the relevant original order or statute.
Today’s land records did not all begin at the same time. Different systems were created for different jobs: measuring fields, collecting land revenue, deciding tenure, recording village house sites, registering transactions and controlling development. That is why an old survey number, a UDR entry, a Natham patta and a planning approval may tell different parts of the story.
Under the Madras Presidency, colonial administrators expanded systematic measurement and revenue settlement, including the ryotwari system associated with Thomas Munro’s administration in the early 19th century. In ryotwari areas, revenue was assessed against individual cultivators or holdings; in zamindari estates, an intermediary estate-holder played a different role; inam lands followed their own grant and tenure histories. These systems co-existed, and they did not affect every village in the same way. Survey numbers, field measurements, village accounts and settlement registers grew out of these administrative needs. Practices and dates varied by district; there was no single survey event that created every record now used in Tamil Nadu.
An old survey number, boundary or classification may come from a particular settlement operation. To trace it, find the original settlement register, village map, old FMB or other surviving record for that village.
A Revenue, Agriculture and Commerce glossary published in 1871 defined “natham” as the site of villagers’ dwellings, distinct from lands attached to the village. This helps explain why a village house-site area could be recorded differently from agricultural fields. It does not, by itself, decide the ownership of any present-day plot.
Original Settlement Register (OSR), Settlement Land Register (SLR), village accounts, old maps and any specific record that identifies the house-site parcel.
The Madras Land Encroachment Act, 1905 became part of the legal framework for dealing with unauthorised occupation of certain government lands. Its application depends on the land’s legal status and the applicable law; it should not be assumed to apply identically to every classification or occupied village house site.
A “poramboke” or “natham” word in one record is not enough to resolve a dispute. Read the underlying record, the relevant statute and the current binding judgments together.
After Independence, Tamil Nadu (then Madras State) used different laws to abolish or change certain estates and inam tenures and to settle eligible lands under ryotwari arrangements. These were not one universal transfer of every parcel into private ownership. The legal result depended on the type of estate or inam, the governing enactment, eligibility and the order passed for that land. Land-ceiling laws formed another, separate part of post-Independence land reform.
Estate or inam records, settlement proceedings, ryotwari patta or other statutory orders, assignment records, appeal orders and court orders where relevant.
The Tamil Nadu Town and Country Planning Act, 1971 established a statutory planning framework distinct from revenue survey and settlement. CMDA operates within its notified metropolitan jurisdiction; DTCP and other competent authorities apply where jurisdiction and law provide. A revenue classification is not a layout approval, and a planning approval is not proof of title.
Verify the exact planning authority, approved layout status, land-use rules and building permissions for the site. Do not assume Chennai metropolitan rules apply everywhere in Tamil Nadu.
UDR is commonly described as a state exercise to update registry and prepare or correct survey and revenue records, including field-level checks and subdivisions where required. A training reference used by the National Academy of Administration describes the commonly cited 1979–1987 period; the specific government order and local records must be checked before attributing an entry to UDR.
Compare pre-UDR settlement registers and FMB with the UDR A-Register, UDR FMB, Chitta/Patta entries, subdivision proceedings and present extracts. A mismatch is a reason to request the underlying file—not to assume either record is automatically correct.
G.O. Ms. No. 1177 dated 30 October 1987 (Commercial Taxes and Religious Endowments Department) is commonly cited for initiating Natham survey and settlement; guidelines followed in December 1987, and G.O. Ms. No. 1971 dated 14 October 1988 (Revenue Department) set out settlement and ground-rent instructions. G.O. Ms. No. 454 dated 13 May 1996 is cited in the judgment as withdrawing the ground-rent levy, after which the scheme was treated as completed. The scheme addressed individual holdings in village natham areas and certain agricultural lands used for non-agricultural purposes. It was separate from UDR, and its history includes rough pattas, enquiries, records and later disputes.
“Grama Natham”, “Natham Poramboke”, “Natham patta”, “Natham Adangal” and an assignment of vacant land are not interchangeable. Identify the exact register, survey sketch, order and factual occupation history for the parcel.
After survey and settlement exercises, revenue departments continued record maintenance, mutation, correction and appeal work. Computerised services later made selected extracts available online, but the digital record is not necessarily the complete historical file and may not show every old boundary or order.
Ask the competent Taluk/Survey and Land Records office for certified copies of the relevant old and current registers, FMB/town-survey sketch, subdivision proceedings, mutation orders and settlement or assignment file.
Later Government Orders and departmental instructions addressed held-over Natham cases, classification/record terminology and patta-related administration. For example, the 2026 Full Bench judgment discusses G.O. Ms. No. 233 dated 5 February 2021, G.O. Ms. No. 221 dated 4 May 2023 and G.O. Ms. No. 869 dated 30 September 2023 in this context. The exact effect of each order depends on its complete text, issuing department, amendments, the parcel and later directions; the dates alone do not create a right to a patta. Do not treat a general summary—or a recent order number alone—as a grant of ownership or a guarantee that a patta must be issued.
Obtain the full official text and annexures of the relevant Government Order, check whether it applies to the village and land category, and confirm later amendments, circulars and orders.
In Nallasivam v. The District Collector, the Full Bench answered the referred question that occupied Grama Natham lands do not vest with the Government and that the Tamil Nadu Land Encroachment Act, 1905 cannot be invoked in respect of occupied Grama Natham lands. This is a significant legal development, but it is not a blanket ruling that every Natham parcel is privately owned, that vacant Natham may be occupied, or that every patta/title dispute is resolved. The official judgment and any later review, appeal, stay or clarifying decision must be checked before relying on it in a live matter.
First establish the exact classification, whether the site is occupied or vacant, the relevant survey and settlement records, the nature of the proceedings and the current binding case law. Obtain legal advice for a specific dispute.
Official portals help locate available Patta/Chitta, A-Register, FMB, TSLR and registration services. A sound property review connects those current extracts to historical settlement records, title deeds, encumbrance searches, boundary verification and planning permissions.
If names, extents, survey numbers, boundaries or classifications conflict, stop and obtain certified records and a professional review before paying an advance or proceeding with a transaction.
DO NOT MIX THESE UP
Use each record for the question it is designed to answer.
Question: How is the parcel recorded in revenue and survey systems?
These records are important but are not, by themselves, a complete title opinion.
Question: What instruments and legal events support the claimed ownership?
Registration and EC searches also have scope limits; a professional title review may be necessary.
Question: What development or land use is permitted under the applicable plan and rules?
Planning approval does not itself prove clear ownership or remove restrictions from a parcel.
A SIMPLE EXAMPLE
Confirm the title chain, the precise survey boundary, access, classification, applicable master plan, layout approval, building rules and any waterbody or public-use restrictions before committing.

Tick off the checks as you collect documents. This is an educational aid, not a certificate that a property is safe to buy.
COMMON QUESTIONS
No. Patta is an important revenue record, but a proper title assessment usually requires the registered instruments, link documents, relevant orders, boundaries and other facts. The weight of each record depends on the case.
No. Planning or layout approval and title are separate matters. Check the approval's validity and conditions, and independently review ownership and encumbrances.
No. The precise record entry, context, historic records, land use and applicable legal framework matter. Do not make a decision from a generic label alone.
No. They refer to distinct administrative exercises. For a particular parcel, compare the original records and the orders governing the relevant exercise.
Not always. Online extracts are useful starting points, but historical or disputed parcels may require original registers, old survey sketches and certified proceedings from the competent office.
No. It explains what to investigate. It cannot decide title, eligibility for patta, buildability or the outcome of a legal dispute for a specific property.
VERIFY FROM THE SOURCE
Use official services to locate available records. For legal conclusions, consult the full statute, Government Order and binding judgment relevant to the specific issue.
This page is general educational information, not legal, survey, tax or planning advice. Government orders, classification labels, jurisdiction and judicial interpretation can change or depend on the parcel. The 2026 Grama Natham Full Bench decision and any later appeal or stay must be checked against the current official court record before this guide is treated as a final legal position.
