# How to Buy Farmland in Tamil Nadu: Patta, Chitta and the Adangal > Tamil Nadu's land records work differently. What patta, chitta, adangal and FMB sketches show, how to check them, and the state-specific traps for farmland buyers. - Canonical: https://www.agriva.ai/blog/farmland-buying-guide-tamil-nadu - Published: 2026-09-16 - Author: Agriva Editorial - Category: Buying guides - Tags: tamil-nadu, patta, chitta, adangal, buying-guide - Reading time: 5 min - Source: Agriva (https://www.agriva.ai) --- Tamil Nadu keeps its land records under a different vocabulary from the rest of the south, and buyers arriving from Karnataka or Telangana frequently ask for the wrong documents. Here is the set you actually need, what each proves, and the traps specific to this state. ## The records **Patta.** The primary document of record, issued in the landholder's name for a specific survey number and extent. It establishes the holder's right to the land in the revenue records. A patta is issued by the tahsildar and shows the patta number, the holder, the survey and sub-division numbers, and the extent. **Chitta.** The account of the holding, historically recording land type and revenue. Chitta and patta were merged into a combined patta-chitta extract, so in practice you request one document. **Adangal.** The cultivation register -- the record of what was grown, season by season, and by whom. The Tamil Nadu equivalent of the crop columns on a Karnataka RTC, and equally underused. It is your independent evidence of whether the land was farmed and what it supported. **A-Register extract.** A fuller record of the survey number, including classification and assessment. Worth pulling where there is any ambiguity. **FMB sketch (Field Measurement Book).** The cadastral sketch showing the parcel's shape, measurements and adjoining survey numbers. This is the document that ties a survey number to a physical location -- see [verifying a survey number](/blog/how-to-verify-survey-number-land). Pull all of these fresh from the state's digital land records service rather than accepting the seller's copies. ## What to check on the patta **Names.** The patta holder must be the seller. Joint pattas are extremely common in inherited land, and **every joint holder must be party to the sale**. A sale by one of several joint patta holders is not clean. **Survey and sub-division numbers.** Identical across patta, deed, EC and FMB. Tamil Nadu sub-divisions can be deep -- 112/3A2B is an ordinary sort of number here -- and a single character matters. **Extent.** Cross-check patta, FMB and deed. Note that Tamil Nadu measures in hectares and ares on official records while the market talks in acres and cents. Convert carefully -- the [land unit converter](/tools/land-unit-converter) covers hectares, ares, acres and cents -- because a great many disputes start as arithmetic. **Classification -- nanjai and punjai.** _Nanjai_ is wetland, irrigated, typically paddy. _Punjai_ is dryland. This affects value, permitted cropping, and how the land is treated for ceiling purposes. A parcel recorded as punjai but priced as nanjai deserves a question. ## The state-specific traps **Natham and grama natham land.** Land classified as village housing site. It sits under a different regime from agricultural land, and natham patta issues have been the subject of repeated policy change and litigation. If a plot is being sold on the strength of a natham patta, get specific advice on its current standing before you rely on it. **Poramboke land.** Government land -- tanks, channels, grazing land, roads. It cannot be privately owned, and encroachment onto poramboke is a live problem, particularly on parcels abutting tank bunds and channels. If the FMB shows poramboke adjoining, walk that boundary with particular care and check that the fence line respects it. This is one of the more common ways a Tamil Nadu parcel turns out to be smaller than advertised. **Land in a tank command or ayacut.** Irrigation rights follow the ayacut record, not proximity. Confirm the survey number appears in the ayacut for that tank or channel, and establish head-reach versus tail-end position.

Relevant across the state's long coastline and around the Nilgiris fringe for other ecological restrictions. ## Water and soil Tamil Nadu's water picture divides between the Cauvery delta districts -- deep alluvial soil, canal and tank irrigation, high-value paddy land -- and the drier interior around Salem, Erode, Tirunelveli and Vellore, where borewells and tank irrigation dominate and the water table has fallen in many blocks. Test borewells in the dry season, ideally between March and May. In the interior, ask neighbouring farmers about re-drilling history. For soil, see [soil types and crop suitability](/blog/soil-types-india-crop-suitability) -- the delta alluvium and the interior red soils support very different crops and carry very different prices. Work the full [site visit checklist](/blog/farmland-site-visit-checklist). ## Eligibility and ceilings Tamil Nadu has its own ceiling legislation applying to the family unit and computed in standard acres. See [land ceiling limits by state](/blog/land-ceiling-limits-by-state-india). Plantation exemptions matter in the hill districts. NRIs and OCI holders cannot purchase agricultural land here or anywhere in India -- see [what FEMA permits](/blog/can-nris-buy-agricultural-land-india) and [inherited farmland and OCI holders](/blog/oci-inheritance-agricultural-land-india). ## Search, register, mutate Order a thirty-year [Encumbrance Certificate](/blog/encumbrance-certificate-explained) through the state registration portal, build [the chain of title](/blog/mother-deed-chain-of-title-explained), and check any [power of attorney](/blog/power-of-attorney-land-purchase-risks) in the chain. Then [pay duty and register](/blog/stamp-duty-registration-agricultural-land), and apply for **patta transfer** -- the Tamil Nadu equivalent of [mutation](/blog/khata-mutation-transfer-explained). Until the patta is in your name, the record shows the seller. If you intend to build, start with [NA conversion](/blog/na-conversion-process-explained) and the local planning authority's land use zone. ## Where to look Browse [farmland near Coimbatore](/properties/tamil-nadu/coimbatore/farmland), [agricultural land around Erode](/properties/tamil-nadu/erode/agricultural), [farmland near Salem](/properties/tamil-nadu/salem/farmland), or [agricultural land around Madurai](/properties/tamil-nadu/madurai/agricultural).
