Every plot-buying checklist tells you to confirm the layout is approved. It is good advice as far as it goes, and it stops short of the thing that actually catches people. A layout can be genuinely, verifiably sanctioned by the planning authority — real permit number, real plan, real seal — and some of the plots inside it still cannot be lawfully sold to you.
They are not disputed, not agricultural and not unapproved. They are mortgaged to the authority itself, held as security until the developer finishes building the roads and drains shown on the plan. The list is usually public. Buyers purchase them anyway, because nobody told them the category exists.
Quick takeaway: At sanction, planning authorities require developers to deposit a proportion of plots as security against unbuilt infrastructure. Those plots are recorded in the sanction and cannot be transferred until the authority releases them. In Telangana, HMDA's development permission system shows mortgaged plots for many layouts. Before you book, get the layout permit number, read the plot schedule in the sanctioned plan, and pull an encumbrance certificate for your specific plot number.
Why the Mortgage Exists
Put yourself on the authority's side of the table. A developer submits a layout over forty acres. The plan shows a 40-foot main road, internal roads, storm-water drains, street lighting, a water line and the mandatory open space. The authority sanctions it. The developer now has several hundred saleable plots and an expensive list of obligations.
What stops the developer from selling every plot and never laying the road?
The answer is that the authority does not release all the plots at once. It requires a proportion to be deposited as security — mortgaged to the authority — and those plots stay locked until the works are complete and the roads and open space reservation are handed over to the local body. If the developer walks away, the authority has assets it can proceed against to fund the shortfall.
It is a sensible mechanism and it usually works. The problem is entirely on the disclosure side: the restriction is recorded in documents the buyer never sees, against plot numbers the buyer has no reason to ask about.
How the Trap Is Sprung
The sale is rarely presented as anything unusual. Several patterns recur:
- The discount with an explanation. A plot in an approved layout at meaningfully below the going rate, with a plausible story — a distress sale, an NRI who needs to exit, a cancelled booking. The discount is real. It is the encumbrance, priced in.
- The brochure that is not the sanction. The buyer is shown a glossy layout with plot numbers, and the approval is confirmed to exist. Both statements are true. The sanctioned plan, which marks the mortgaged plots, is never produced.
- An agreement to sell, not a sale deed. The developer cannot convey clean title today, so the transaction is structured as an agreement with registration promised after release. Sometimes release genuinely follows. Sometimes the works stall and the buyer is holding a contract over a pledged plot.
- A resale that inherits the problem. The first buyer bought a mortgaged plot without realising, and is now selling in good faith. Nobody in the chain is lying and the plot is still encumbered.
What a sale deed does not do: executing and registering a sale deed over a mortgaged plot does not extinguish the authority's charge. Registration records a transaction; it does not adjudicate title or clear an existing encumbrance. Buyers assume the sub-registrar would refuse to register an encumbered plot. That is not the sub-registrar's function.
The Four Checks
1. Get the layout permit number — and the plan behind it
Ask for the LP or permit number and the sanctioned layout plan, not the marketing layout. Mortgaged plots are normally hatched or shaded on the sanctioned plan and listed by plot number in the sanction conditions. Obtain it from the authority rather than the seller where you can. A seller who will not part with the permit number has answered your question.
2. Search the authority's own register
In Telangana, search HMDA's development permission management system for the layout and read the plot schedule; mortgaged plots are shown for many layouts. For parcels near Hyderabad that changed jurisdiction during boundary revisions, check both the HMDA and DTCP portals — some appear on both systems. Elsewhere, the sanctioned plan and its conditions remain the primary record.
3. Pull an encumbrance certificate for the specific plot
For that plot number, over a meaningful period — not for the survey number generally and not for the layout as a whole. The EC is the independent cross-check on whatever the seller has told you about charges.
4. Ask for the release, in writing, if it is claimed
If the seller says the mortgage has been released, that release is a document. Ask for it and check that it covers your plot number. Partial releases are normal as works complete in phases, so a genuine release for the layout does not necessarily include the plot you are buying.
What Else Approval Does Not Guarantee
Once you start reading the sanctioned plan rather than the brochure, three further gaps become visible. They are the same class of problem — approval is a statement about a drawing, not about the ground.
| What buyers assume | What approval actually means | How to check |
|---|---|---|
| Roads and drains exist | They are sanctioned on the plan; construction is a separate obligation | Walk the site against the plan |
| Open space and roads belong to the public body | Handover of OSR and roads to the local body is a step that may not have happened | Ask for the handover record |
| Every plot is saleable | Mortgaged plots are not, until released | Plot schedule, authority register, EC |
| Plot dimensions match the deed | Site boundaries can diverge from sanctioned dimensions | Measure against the sanctioned plan |
That last row is where a 3D view of the sanctioned layout earns its keep — matching plot number, frontage and dimensions against what was actually approved is far easier when you can see the layout properly than when you are comparing a folded A3 print to a boundary stone.
If You Have Already Bought One
This is not automatically a lost cause, and panic is the wrong response. The mortgage is a temporary security, and release is the normal outcome once the developer completes the works.
- Establish the current status from the authority for your plot number specifically — whether it remains mortgaged, and what obligations are outstanding.
- Find out what is actually pending. If the roads are substantially built and the remaining works are minor, release is likely and the practical question is timing.
- Identify who else is affected. Mortgaged plots come in blocks, so you are rarely the only buyer in the layout with this problem. Collective pressure on the developer, or a collective approach to the authority, moves faster than one purchaser.
- If the project is registered with RERA, the promoter's obligations regarding completion and the authority's conditions fall within the regulator's remit. Check the registration and the declared completion timeline — the state RERA portal is the place to start.
- Take legal advice on your specific deed before making further payments. What you signed — agreement to sell versus registered conveyance — changes your position materially.
Note: Layout sanction procedure, the proportion of plots held as security, the terminology used and the extent to which registers are publicly searchable all vary by state and authority. This article describes the mechanism and the checks that apply generally, using HMDA as the clearest documented example. For a specific plot, verify with the sanctioning authority and take independent legal advice on the title before paying.
Frequently Asked Questions
What is a mortgaged plot in an approved layout?
When a planning authority sanctions a plotted layout, it needs a guarantee that the developer will actually build the roads, drains, street lighting and other infrastructure shown on the plan, rather than selling every plot and disappearing. So it requires the developer to deposit a proportion of the plots with the authority as security. Those plots are recorded as mortgaged in the sanction, they remain legally untransferable until the developer completes the obligations and the authority formally releases them, and in Telangana the HMDA development permission system shows them publicly for many layouts.
Can I buy a mortgaged plot if the price is attractive?
You cannot buy it cleanly, which is the point. The plot is pledged to the authority, so the developer does not have an unencumbered title to convey. A sale deed executed over a mortgaged plot does not defeat the authority's charge. If the developer never completes the infrastructure, the authority can proceed against exactly those plots, and you would be arguing your case as a purchaser of encumbered land. The low price reflects the encumbrance rather than a bargain.
How do I check whether a plot is mortgaged?
Start with the sanctioned layout plan itself, which marks the mortgaged plots, usually hatched or shaded and listed by plot number in the sanction conditions. Get the plan from the authority rather than from the seller. In Telangana, search the HMDA development permission management system for the layout and read the plot schedule. Separately, pull an encumbrance certificate for the specific plot from the registration department. If the seller will not give you the layout permit number, treat that as the answer.
Does the mortgage ever get released?
Yes, and routinely. It is a temporary security, not a permanent restriction. Once the developer completes the roads, drains, water supply, street lighting and the other works to the authority's satisfaction, and hands over the open space reservation and roads to the local body, the authority issues a release. After release those plots become ordinary saleable plots. The question for a buyer is never whether release is possible but whether it has happened for your plot number, in writing, as at today.
Is this only a Telangana or HMDA issue?
No. The mechanism of holding security against unbuilt infrastructure is common to plotted layout sanction across Indian planning authorities, although the terminology, proportion and the extent of public disclosure vary. HMDA is simply the clearest example because its plot schedules are publicly searchable. In states where the register is less accessible, the sanctioned layout plan and its conditions remain the primary document, and the encumbrance certificate remains the cross-check.
What else does layout approval not guarantee?
Approval means the plan was sanctioned, not that the ground matches it. Three things commonly diverge: the infrastructure may not be built even though it is drawn, the open space reservation and roads may not yet have been handed over to the local body, and individual plot boundaries on site may not match the sanctioned dimensions. Walk the site against the approved plan. The layout permit number, the plot schedule and the physical site should agree with one another before you pay anything.
