Updated for 2026 · Splitting a survey number into subdivisions and getting separate pattas issued.
- Needed when a survey number is split among heirs or buyers.
- Apply at the taluk office with deed, patta and FMB.
- A surveyor measures the land before subdivision numbers are issued.
- Until subdivided, everyone shares one patta — a practical obstacle.
- Registering a sale is not the same as subdividing the patta.
Why subdivision matters
Buying part of a survey number, or inheriting a share of family land, does not by itself give you a separate revenue record. Registration records the transaction; the revenue record still shows the parent survey number, often with several names against it.
That creates real problems later. A bank lending against the land wants a patta that identifies your parcel. A future buyer wants the same. And where several names sit on one patta, any transaction tends to require everyone's cooperation — which is manageable among siblings today and considerably harder a generation later, when the holders are cousins spread across different cities.
When you need it
| Situation | Why subdivision is required |
|---|---|
| Partition among heirs | Each heir needs a patta for their own share |
| Sale of part of a parcel | Buyer needs a patta for the portion bought |
| Plot development | Individual plots need separate records |
| Gift or settlement of a portion | Recipient needs a distinct record |
How to apply
2. Collect the existing patta and chitta for the parent survey number.
3. Obtain the FMB sketch for the survey number.
4. Apply at the taluk office, or through an e-Sevai centre where available.
5. Attend the field measurement when the surveyor visits — being present matters.
6. New subdivision numbers are assigned and separate pattas issued.
Be present at the measurement if you possibly can, along with the neighbouring holders. Boundaries agreed on the ground in everyone's presence tend to stay agreed; boundaries fixed in someone's absence are the ones that resurface as disputes.
What commonly delays it
- Boundary disagreement with a neighbour or between co-holders — the measurement cannot be finalised.
- Missing or unregistered partition deed — an oral family arrangement is not enough.
- Name mismatches between the deed, the patta and identity documents.
- Encroachment discovered during the measurement.
- Classification issues — check the A-Register if any part may be poromboke.
Most of these are document problems rather than legal ones, and most are fixable before you apply. Reconciling the spelling of names across the deed, the patta and Aadhaar in advance removes one of the commonest causes of a returned application.
Subdivision, mutation and registration are three different things
These get conflated constantly, and the distinction is worth holding onto. Registration records the transaction at the sub-registrar office. Mutation, or patta transfer, changes the name on the revenue record. Subdivision splits one survey number into separate parcels with their own numbers. Buying half a survey number needs all three — and doing only the first leaves you with a registered deed and no revenue record of your own.
What it costs and how long it takes
The application fee for subdivision is modest — this is not an expensive process in government charges. What varies enormously is the time, because the critical step is the surveyor's field visit, which is scheduled around their workload. A straightforward subdivision where boundaries are agreed and documents are in order may complete in a few weeks. Where there is a disagreement, a missing document or an encroachment discovered on measurement, it can run to several months.
Two things shorten it more than anything else. First, submit complete documents the first time — a registered deed covering the division, the current patta and chitta, and the FMB sketch, with names spelled consistently across all of them. Second, be present at the measurement with the neighbouring holders, so that any boundary question is settled on the spot rather than generating a fresh round of correspondence. Applications that stall almost always stall at one of those two points.
Frequently asked questions
What is patta subdivision?
Splitting one survey number into separate subdivisions so that each holder receives a distinct patta for their own portion.
Where do I apply for subdivision?
At the taluk office, or through an e-Sevai centre where available, with the registered deed, existing patta and the FMB sketch.
Is registration of a sale enough?
No. Registration records the transaction. You still need mutation to change the name on the revenue record, and subdivision to obtain a separate patta for your portion.
Does a surveyor have to visit?
Yes, a field measurement is normally carried out before subdivision numbers are assigned. Attend if you can, along with the neighbouring holders.
What if a co-holder will not cooperate?
Subdivision generally needs a valid registered partition or transfer document. Where holders disagree, the matter usually has to be resolved legally before the revenue record can be split.
