Land in Maharashtra is identified by numbers, and the numbers are not consistent across documents in the way a buyer might reasonably expect. The same plot can appear as a survey number on one document, a gat number on another and a hissa of either on a third, and a buyer who does not understand the vocabulary can mistake an ordinary difference for a problem, or worse, miss a genuine problem because they assumed the numbers would sort themselves out. Learning to read how land is identified is what lets you perform the single most important check in any land purchase: confirming that every document is describing the same piece of ground.
The vocabulary
The survey number is the older system of land identification, assigned when the land was originally surveyed. The gat number, or group number, comes from a later consolidation of survey numbers into larger units for revenue purposes, so a single gat number often corresponds to several older survey numbers combined. The hissa is a subdivision: where a survey or gat number has been split among owners or parcels, each part is a hissa of the parent number, written as the parent number followed by the hissa number. So a full identification might read as a gat number, or a survey number with a hissa, and the same physical plot might be describable in more than one of these forms depending on which record and which era you are looking at. Understanding this is the foundation for everything that follows, because it explains why the numbers differ across documents without any error having occurred. A buyer who knows that survey numbers were consolidated into gat numbers, and that both can be subdivided into hissas, can read the difference between an old document and a new one as history rather than as a discrepancy.
Why the numbers differ across documents
Because the systems changed over time, older documents may refer to survey numbers while newer records use gat numbers, and a resurvey or a consolidation can mean the number on a decades-old title deed differs from the number on a current 7/12 extract. This is not automatically a problem; it is often just the record catching up with successive administrative reforms. But it does mean that a buyer cannot simply glance at two documents, see two different numbers, and assume either that everything is fine or that something is wrong. The difference has to be understood and reconciled rather than assumed away in either direction. The identity of the land is confirmed by the numbers agreeing. If they do not agree, the burden is on the seller to explain why, in documents. The reconciliation is exactly what a title search establishes: that the survey number on the old deed corresponds, through the consolidation records, to the gat number on the current extract, and that the chain of numbers describes one continuous piece of land through all its administrative renamings. A buyer should expect their lawyer to walk that chain and confirm it, rather than accepting that a modern gat number and an old survey number obviously refer to the same plot. Sometimes they do; sometimes the difference conceals a subdivision or a boundary change that matters, and only the reconciliation tells you which.
The identity check across all documents
The practical heart of this whole subject is a single check, and it is the one no buyer should skip. The land-identification numbers, survey or gat, with the hissa where applicable, must match across the four key documents: the 7/12 extract, the NA order, the sanctioned plan and the agreement. All four must describe the same parcel, identified consistently, and where the numbering system differs between an older and a newer document the correspondence must be established rather than assumed. This is the check that confirms the conversion order, the plan and the agreement all relate to the plot the extract shows the seller owns. When the numbers do not reconcile across the four documents, that is a question to be answered before money moves, not after. It may be innocent, a document drawn up using an older number, or it may be serious, a conversion or a plan that relates to a different parcel from the one being sold. The buyer cannot tell which without resolving it, and the resolving is far cheaper before a deposit than after. This is precisely the check that a bank's lawyer will run and refuse the loan over if it fails, which is another reason to run it yourself first.
Units of area, and their conversions
Alongside the identification numbers, area is recorded in units that trip up buyers used to square feet. Land in rural Maharashtra is commonly measured in guntha, are and hectare, with an acre and its forty guntha still in colloquial use. Roughly, one guntha is about a thousand square feet, forty guntha make an acre, and a hectare is about two and a half acres. The exact conversions matter, because a plot described as so many guntha needs to be translated into a figure you can compare against a built area or a per-square-foot price. The reason to be careful with the units is that the area, like the number, must reconcile across the documents, and a mismatch of a few guntha between the extract, the plan and the agreement is worth chasing down rather than rounding away. A small area discrepancy can point to a subdivision that was not carried through cleanly, or to documents describing the land at different levels of precision, and either way it is the kind of thing to understand before committing. A buyer who converts the units carefully and checks the area figures against one another is doing the same identity check on the size of the land that the numbers do on its location.
The subdivision trap: undivided share versus demarcated
plot The hissa concept hides a genuine trap worth naming clearly. When a larger parcel is subdivided, a buyer needs to know whether they are buying a specific, demarcated portion with defined boundaries, or an undivided share in a larger undivided parcel. These are very different things. A demarcated plot is a defined piece of ground you can point to and fence. An undivided share is a fractional interest in a larger whole that has not been physically partitioned, which means you own a proportion of the whole rather than a specific piece of it, and cannot simply build on the part you assume is yours. Buying an undivided share when you believe you are buying a demarcated plot is a serious misunderstanding, and it is one the numbering can obscure. A buyer should confirm, explicitly, that the hissa they are buying is a properly subdivided, demarcated portion with its own boundaries and, ideally, its own separate entry in the records, rather than an unpartitioned share. The distinction determines whether you can build, fence and deal with the plot as your own, and it is exactly the sort of thing that is clear once asked and disastrous when assumed.
Record versus reality on the ground
There is one more gap to close, which is between what the record says and what exists on the ground. The documents describe the land in numbers and areas; the actual boundaries are physical, and the two do not always coincide perfectly. A formal measurement, sometimes called a mojni, carried out by the land records office establishes the actual demarcated boundaries of a plot against the record, and it is what turns a paper description into a fenced reality. Where there is any doubt about where a plot's boundaries actually lie, this measurement is the tool that settles it. Boundary disputes and encroachments arise precisely in the gap between record and reality, where a neighbour's wall sits over a line, or where the physical occupation does not match the paper. A prudent buyer, especially of raw land, confirms not only that the documents reconcile but that the plot on the ground matches the plot on paper, by walking the boundaries and, where warranted, obtaining a fresh measurement. It is the physical counterpart of the documentary identity check, and it is the step that catches the problem the papers alone cannot show.
The role of the land records office
The authority that maintains and measures the land records, the office responsible for the survey and settlement records, is the source of truth for how a plot is identified and where its boundaries lie, and a buyer should know that its records and its measurements are what ultimately govern. When there is doubt about a boundary, a subdivision or the correspondence between an old survey number and a current gat number, it is this office's records and, where necessary, a fresh measurement by it that settle the question rather than anyone's assertion. The record is authoritative, and the measurement on the ground is how the record is made physical. For a buyer, the practical use of this is knowing where to go when something does not reconcile. If the numbers on the documents do not agree, or the area does not match, or the boundaries on the ground seem to differ from the paper, the resolution runs through the land records office rather than through a seller's explanation. A buyer, usually through their lawyer, can obtain the relevant records and, where warranted, request a measurement, and that is the definitive way to establish what the plot actually is. The seller's account is a starting point; the land records office is where the account is confirmed or corrected.
When a plot has been consolidated or renumbered
Because survey numbers were consolidated into gat numbers and plots have been subdivided over the decades, a specific plot may have a history of renumbering that a buyer needs their lawyer to trace rather than assume. A parcel that was one survey number may now be part of a larger gat number, or a survey number may have been split into several hissas, and the current record has to be connected back through these changes to the historical documents to confirm that the chain of title runs unbroken to the plot being sold. This tracing is a normal part of a proper title search and is exactly the sort of work that distinguishes a real search from a glance at the current extract. The risk a buyer avoids by insisting on this tracing is buying a plot whose current identification does not cleanly connect to the ownership history, which is a defect that surfaces later at financing or resale. A plot whose renumbering history has been traced and reconciled is a plot whose identity is secure; one where the current number simply floats, unconnected to a clear chain, is a plot with a question mark over exactly what is being conveyed. The consolidation and renumbering are ordinary administrative history, but connecting through them is essential work, and a buyer should confirm it has been done rather than assume the current number tells the whole story.
How to verify, and how we handle it
Reduced to practice, the verification runs on two tracks. On paper, confirm that the survey or gat number and hissa, and the area, reconcile across the 7/12 extract, the NA order, the sanctioned plan and the agreement, with your lawyer establishing the correspondence where an older number differs from a newer one. On the ground, confirm that the plot's physical boundaries match the record, walking them and obtaining a measurement where there is any doubt, and confirming that a subdivided plot is a demarcated portion rather than an undivided share. Together, the two tracks confirm that the land you are buying is the land the documents describe and the land that physically exists. For our own houses, the land-identification numbers reconcile across the extract, the conversion order and the sanctioned plan by construction, because the conversion and the layout were obtained for the same identified parcel, and the numbers are available for a buyer's lawyer to check from the first serious conversation. That reconciliation is not a courtesy; it is the foundation of a clean title, and a project where it holds is a project where the most basic question, whether every document describes the same piece of ground, has already been answered. Ask for the numbers, reconcile them across the documents, confirm the plot on the ground matches the plot on paper, and the vocabulary of survey, gat and hissa becomes a tool you can use rather than a source of confusion.
