Sarjapur–Attibele Road runs almost to the state line. Drive a few minutes past Attibele and you are in Tamil Nadu, near Hosur. For a first-home buyer this raises a fair question that few people ask out loud: which state's papers am I supposed to check?
The answer is simpler than it sounds. One property sits in one state, and that state's offices hold all of its records. The trouble starts only when people mix the two vocabularies.
Start with one line in the title deed
Every sale deed has a part called the schedule of property. It describes the land in government terms: the survey number, the village, the hobli (a group of villages, in Karnataka) and the taluk. That line decides everything else.
- If the taluk is in Karnataka, such as Anekal, the Karnataka set of records applies.
- If the taluk is in Tamil Nadu, such as Hosur, the Tamil Nadu set applies.
A marketing address like "near Attibele" or "Hosur Road" is not a government description. Ask for the schedule line before anything else.
Two states, two record systems
People often say a khata is just Karnataka's word for a patta. It is not. They are different records, kept by different offices, for different reasons.
- Khata (Karnataka). A property-tax account kept by the local body. It tells you who gets the tax bill.
- Patta (Tamil Nadu). A land revenue record kept by the revenue department, under the Tamil Nadu Patta Pass Book Act, 1983. It tells you who the land register lists against a survey number.
The closer match to a patta in Karnataka is the RTC, also called the pahani. That is Karnataka's record of rights for farmland and other revenue land, kept under the Karnataka Land Revenue Act, 1964.
A quick side-by-side
| What you want to know | Karnataka | Tamil Nadu |
|---|---|---|
| Who the land register lists | RTC (pahani) | Patta and chitta |
| Who pays property tax | Khata, from the local body | Tax assessment, from the panchayat or municipality |
| Registered sales and loans on the property | Encumbrance certificate on Kaveri | Encumbrance certificate on TNREGINET |
| Project registration | K-RERA, rera.karnataka.gov.in | TNRERA, rera.tn.gov.in |
Why the wrong portal is dangerous
Each state's portal only knows its own properties. Type a Tamil Nadu survey number into Karnataka's portal and you get no result. A property with no registered loans also gives no result. On screen, the two look the same.
So "nothing found" means something only when you are sure you searched the right state, the right office and the right spelling of the village.
What neither record can tell you
A khata and a patta are both useful. Neither one proves ownership. In India, ownership is shown by an unbroken chain of registered sale deeds. Section 17(1)(b) of the Registration Act, 1908 makes registration compulsory for a sale of immovable property. Section 49 of the same Act says an unregistered document cannot affect the property.
Think of it like this. The deeds are the proof. The khata or patta shows whether the government's other records agree with that proof.
If a listing mixes up the two states
Many property listings are copied from a template. You may see a plot in Tamil Nadu described with a "khata" and a Karnataka RERA number. That does not always mean fraud. It does mean nobody checked, so you should check everything yourself.
- Ask for the survey number, village and taluk in writing.
- Look up the project on the RERA portal of the state the land is in.
- Ask for the approved plan and read who approved it.
One trap is the same in both states
Registering your sale deed does not update the other records by itself. In Karnataka you apply to the local body to move the khata into your name. In Tamil Nadu you apply to the Tahsildar to move the patta. In both states, the buyer has to file it.
A worked example: one listing, two checks
Here is an illustrative case. The names and numbers are made up, but the steps are real.
Priya and Arun have a budget of about ₹70 lakh for their first flat. They see a listing that says "2 BHK near Attibele, Hosur Road, khata ready". They ask the seller for the schedule of property. It reads: survey number 45/2, a village in Anekal taluk, Bengaluru Urban district. That settles it. The flat is in Karnataka, so every check runs through Karnataka offices.
Now suppose the schedule had said Hosur taluk, Krishnagiri district. The same "khata ready" line would then make no sense, because a Tamil Nadu flat has no khata. That one mismatch tells them to slow down and ask more questions.
The cost of doing this check is small. A lawyer's title report on a flat might cost, say, ₹10,000 to ₹25,000 (illustrative; fees vary by city and by lawyer). On a ₹70 lakh purchase, ₹25,000 is about 0.36% of the price. That is plain arithmetic: 25,000 ÷ 70,00,000 × 100. It is cheap insurance against buying the wrong paper trail.
Step by step: which records to ask for
- Get the schedule of property in writing. Survey number, village, hobli or firka, taluk and district.
- Confirm the state from the taluk. Not from the PIN code, and not from the road name.
- Pull the encumbrance certificate from that state's portal. Ask for a period long enough for your lawyer, often 13 to 30 years.
- Check the land record of that state. RTC in Karnataka, patta and chitta in Tamil Nadu. Match the survey number and extent with the deed.
- Check the tax record. Khata in Karnataka, the local body's assessment in Tamil Nadu. The name should match the seller.
- Check the project on that state's RERA portal. Match the registration number, the promoter's name and the land details.
- Ask your lawyer to read the chain of sale deeds. This is the step that actually shows ownership.
Checklist to carry to the site visit
- Copy of the schedule of property from the latest sale deed
- RERA registration number, already looked up on the right state's portal
- Name of the local body that collects tax for this address
- Name of the sub-registrar office where the sale will be registered
- A list of the documents the builder or seller has promised to show you
Common mistakes near a state border
- Trusting the PIN code. Postal areas are drawn for delivering post, not for land records.
- Searching on the wrong portal and feeling relieved. An empty result on the wrong site proves nothing.
- Asking for a patta in Karnataka, or a khata in Tamil Nadu. If someone produces one anyway, ask what it really is.
- Forgetting the after-sale updates. Your sale deed alone does not change the tax or land record into your name.
- Using a lawyer who only knows the other state. Local practice matters. Ask which offices they work with.
