Land aggregation and title: what actually kills a deal at diligence?

Lakshita Sanwal· Founder, Propah Realty, Bengaluru· Last reviewed: 7 September 2026· 14 min read

An aggregation dies on its smallest parcel, not its largest. In Karnataka the recurring killers are specific and mostly knowable in advance: granted land under PTCL, section 79B — still in force, so a company or trust cannot buy agricultural land even though individuals now can — storm water drain and lake buffers, and an acquisition notification nobody searched for. Sequence the difficult parcels first.

The aggregation problem, stated plainly

You need eight contiguous parcels. Seven are clean. The eighth has a defect that cannot be cured, and without it the layout does not work. You have now spent a year and a great deal of money on seven parcels that are worth considerably less as a fragment than they were as a scheme.

Everything below follows from that. The order in which you tackle parcels matters more than the speed at which you tackle them, and the correct sequence is hardest first — which is the opposite of what momentum and enthusiasm both suggest.

The Karnataka-specific killers

Granted land, and PTCL

Land granted to Scheduled Caste and Scheduled Tribe beneficiaries carries restrictions on alienation. A transfer in breach can be challenged and set aside long after it was made, and the chain of subsequent purchasers does not cure it. This is the defect that most often surfaces in an outer-ring aggregation, and it is the one least likely to be visible in a casual reading of the title chain. It has to be searched for specifically.

Section 79B is still in force

This is widely misunderstood, and the misunderstanding is expensive. The Karnataka Land Reforms (Amendment) Act, 2020 removed the requirement under section 79A that a buyer of agricultural land be an agriculturist — so any Indian citizen may now buy, regardless of occupation.

What the 2020 amendment did not change

Section 79B remains. Companies, co-operative societies, associations of persons, trusts and institutions still cannot purchase agricultural land, except for specified agricultural or horticultural purposes. A developer buying through an SPV faces a restriction an individual promoter does not.
Ceiling limits under sections 63–68 still apply. The 2020 amendment doubled the baseline from 10 to 20 units, with larger families able to hold up to 40. An aggregation can run into the ceiling before it runs out of sellers.
NRIs remain barred from agricultural land under FEMA, irrespective of the Karnataka amendment. An NRI co-promoter is a structuring question, not a formality.

The 2020 amendment opened the door for individuals and left it shut for entities. Plenty of deals have been structured as though it opened both.

Storm water drain and lake buffers

A rajakaluve running through or beside a parcel removes buildable area and can remove the scheme. Buffers are enforced under the Revised Master Plan and National Green Tribunal directions, and consequences are real: penalties reported from ₹5,000 per square metre, demolition of structures in the buffer, and loan rejection or recall on affected properties.

On the widths themselves we will be honest rather than precise: published sources conflict. A 2025 BBMP notification is cited both as roughly 15 metres total for a primary drain and as roughly 25 metres, with about 10 metres for secondary and 5 metres for tertiary drains. That is not a difference you can absorb in a layout. Establish the drain classification and the applicable buffer for your specific survey number with the authority, on the survey sketch, before you commit — not from any published table, this one included.

Acquisition notifications

A preliminary or final acquisition notification — BDA, a road widening, a metro alignment, a highway — can sit against a survey number without any visible sign on the ground and without appearing in an encumbrance certificate. It has to be searched for. A parcel under notification is not a negotiation; it is a different transaction entirely.

Tenancy claims

Historical tenancy claims under the land reforms legislation can attach to agricultural land and surface at registration or later. Old, dormant and undecided claims are a recognised category of defect in Karnataka agricultural land and belong on the search list rather than in the assumptions.

Partition, minors and coparcenary

A family partition that excluded a coparcener, or a sale of a minor’s undivided share without proper sanction, produces a claim that can be raised long afterwards. In an aggregation with multiple family-held parcels, this is less an exception than a pattern.

Conversion that does not cover your extent

Conversion obtained at the parent survey number, then the land subdivided, leaving specific plots whose extent was never covered. It reads as converted because a conversion order exists. The order must cover your survey number and your extent.

How to sequence an aggregation

Map every survey number before approaching anyone. RTC and mutation history, conversion status, khata classification, drain and buffer position, acquisition search, and a PTCL check on each. Do this on paper before the first conversation, because the moment you start buying, your negotiating position on the remaining parcels deteriorates.
Identify the parcels that can kill the scheme — the ones without which the layout does not work — and secure or clear those first, even though they are the hardest. Money spent on the easy parcels first is money spent on optionality you may never exercise.
Use options and agreements to sell, not outright purchases, until the whole set is secured. An option costs a fraction and does not strand capital in a fragment.
Assume the holdout exists and price for it. The parcel that completes a scheme is worth more to you than to anyone else, and the seller usually works this out. Design a layout with a fallback that does not require it, if one is possible at all.
Run title in parallel, not sequentially. Eight parcels searched one after another is eight times the elapsed time, and elapsed time is when a seller changes their mind.
Get a title opinion that states what it did not check. An opinion that reads as unqualified comfort on agricultural land in Karnataka is usually an opinion with a narrow scope.
Keep the payment structure tied to clearance. Advance against milestones and resolved queries, not against goodwill.

What a thirty-year chain is actually for

Not to prove the seller owns the land — the current record does that. It is to show how they came to own it, because most Karnataka title defects are inherited rather than created. A grant three transfers back, a partition without a signature, a conversion covering a different extent: none of these appear in the present-day record, and all of them survive it. e-Khata has improved what is verifiable digitally, but it evidences the current position rather than the history that can unwind it.

What this does not cover

Buffer zone widths for rajakaluve are stated inconsistently across published sources — primary drains are cited at both roughly 15 m and roughly 25 m. The conflict is flagged rather than resolved. Establish the applicable buffer with the authority for your survey number.
Penalty figures are as reported and are not a statutory schedule.
PTCL, tenancy and coparcenary positions are summarised at a level useful for identifying risk, not for assessing a specific claim. Each is heavily litigated and fact-dependent.
Ceiling limits and section 79B are as published following the 2020 amendment; the position has changed before and may change again.
This is general information, not legal advice or a title opinion. Engage an advocate who acts only for you and who will state the scope of their search.

What kills a land deal at due diligence in Karnataka?

Most often granted land restrictions under PTCL, which can void a transfer decades later and are not cured by subsequent purchases; section 79B, which still bars companies, trusts and societies from buying agricultural land even though individuals were freed by the 2020 amendment; storm water drain and lake buffers that remove buildable area; an acquisition notification that appears nowhere on the ground or in an encumbrance certificate; historical tenancy claims; and partition defects involving minors or excluded coparceners.

Can a company buy agricultural land in Karnataka?

Generally no. The Karnataka Land Reforms (Amendment) Act, 2020 removed the section 79A requirement that a buyer be an agriculturist, so any Indian citizen may now purchase — but section 79B remains in force, and companies, co-operative societies, associations of persons, trusts and institutions still cannot buy agricultural land except for specified agricultural or horticultural purposes. A developer acquiring through an SPV therefore faces a restriction that an individual promoter does not, and structuring around it is a legal question to settle before offers are made.

What is PTCL land and why is it a problem?

Land granted to Scheduled Caste and Scheduled Tribe beneficiaries, which carries restrictions on alienation. A transfer made in breach of those restrictions can be challenged and set aside long after it occurred, and the fact that the land has since passed through several purchasers does not cure the defect. It is the defect most likely to appear in an outer-ring Bengaluru aggregation and least likely to be visible in a casual reading of the title chain, so it has to be searched for specifically on every survey number.

What is the rajakaluve buffer zone in Bangalore?

Published sources conflict, which is itself the important point. A 2025 BBMP notification is cited both as roughly 15 metres total for a primary drain and as roughly 25 metres, with around 10 metres for secondary and 5 metres for tertiary drains, enforced under the Revised Master Plan and NGT directions. That discrepancy is far too large to absorb in a layout. Establish the drain classification and the applicable buffer for your specific survey number with the authority, on the survey sketch, rather than from any published table.

What happens if you build within a storm water drain buffer?

Reported consequences include penalties starting at around ₹5,000 per square metre, demolition of structures within the buffer, and rejection or recall of loans on affected properties. Enforcement runs through BBMP surveys and notices under National Green Tribunal directions, and has extended to court-backed removals. For a developer the commercial effect arrives earlier than the legal one: buyers' banks decline the file, and a project that cannot be financed by its buyers cannot be sold.

In what order should a developer acquire parcels in a land aggregation?

Hardest first, which is the opposite of what momentum suggests. Map every survey number before approaching anyone — RTC and mutation history, conversion status, khata, drain and buffer position, acquisition search and a PTCL check. Then identify the parcels without which the layout does not work and secure or clear those first. Use options and agreements to sell rather than outright purchases until the full set is secured, so capital is not stranded in a fragment if one parcel proves incurable.

Why does a thirty-year title chain matter?

Because it shows how the seller came to own the land, not merely that they do — and most Karnataka title defects are inherited rather than created. A grant three transfers back, a partition missing a signature, a conversion order covering a different extent: none of these appear in the present-day record, and all of them survive it. e-Khata has improved what can be verified digitally, but it evidences the current position rather than the history capable of unwinding it.

Can an NRI buy agricultural land in Karnataka after the 2020 amendment?

No. FEMA bars NRIs, PIOs and OCI cardholders from purchasing agricultural land, plantation property and farmhouses anywhere in India, and Karnataka's 2020 amendment to its own land reforms legislation does not affect that position. Such land may be inherited where the previous owner acquired it lawfully. An NRI co-promoter in a land aggregation is therefore a structuring question to resolve with advisers before any offer is made, not a detail to handle at registration.

Sections 79A, 79B and the ceiling provisions of the Karnataka Land Reforms Act and the effect of the Karnataka Land Reforms (Amendment) Act, 2020; PTCL restrictions on granted land; FEMA restrictions on NRI purchase of agricultural land; and rajakaluve buffer enforcement under the Revised Master Plan and NGT directions checked across published guidance in September 2026. Buffer widths are stated inconsistently in published sources and the conflict is flagged rather than resolved. Penalty figures are as reported, not a statutory schedule. This is general information, not legal advice or a title opinion.

Still deciding, or want this applied to your own situation?

Tell us where you are and we will come back to you. The first conversation is free, and we will tell you plainly if we are not the right people for it.

Secure the parcel that can kill the scheme first.

Seven clean parcels and one incurable eighth is not seven-eighths of a project. It is a fragment, bought at scheme prices.
