Property fraud and legal disputes often come down to one thing: documents that were never properly checked. A beautiful flat or a well-located plot is worthless if the title is disputed, approvals are missing or the property carries hidden loans. Through A Property Agency, I strongly encourage buyers to treat document verification as non-negotiable.
Here is a checklist of key documents to verify. Names and formats vary by state, so always confirm local requirements with a qualified lawyer.
Key takeaways
- Property documents prove ownership, approvals and freedom from legal disputes.
- The exact documents differ by state, property type and whether it is new or resale.
- A qualified lawyer should verify title and documents before purchase.
- Keep originals safe and maintain digital copies.
- Never rely only on photocopies or verbal assurances.
1. Title deed / sale deed
The title deed proves ownership. Verify:
- The seller's name matches their ID.
- Property description, area and boundaries match the actual property.
- The deed is properly registered.
2. Chain of ownership (mother deed)
Review previous sale deeds showing how ownership passed over the years — ideally for several decades. Gaps or inconsistencies in the chain are warning signs.
3. Encumbrance certificate
An encumbrance certificate, obtained from the sub-registrar's office (often online in many states), shows registered transactions on the property, including mortgages. It helps confirm the property is free from registered loans or legal dues.
4. Land records and mutation
Check land records in revenue department records and mutation entries showing the current owner. Many states provide online land records portals.
5. Land use and conversion
For plots and projects, verify the land is approved for residential use. Agricultural land usually requires conversion approval before residential construction.
6. Approved building plan and layout
The local development authority or municipal body must approve the building plan and layout. Check that the construction matches the approved plan — extra floors or deviations can cause legal problems later.
7. Commencement certificate
For under-construction projects, the commencement certificate from the local authority confirms permission to begin construction.
8. Occupancy certificate (OC) and completion certificate
For ready properties, the occupancy certificate confirms the building is fit for occupation and was built as per approvals. The completion certificate confirms construction was completed as per the approved plan. Buying a property without an OC can create problems with utilities, loans and resale.
9. RERA registration
For eligible projects, verify registration on the official state RERA portal under the Real Estate (Regulation and Development) Act, 2016. See how to check RERA registration.
10. Property tax receipts
Check that property tax has been paid up to date. Unpaid taxes can become your liability after purchase.
11. Utility bills and dues
Verify electricity, water and gas bills are paid and connections are legal.
12. Society NOC and share certificate
For flats in housing societies, obtain an NOC from the society for the sale, and check maintenance dues are cleared. In some states, a share certificate shows membership in the society.
13. Loan closure documents
If the seller had a home loan on the property, obtain the loan closure letter and ensure original documents have been returned by the lender.
14. Power of attorney (if applicable)
If someone sells on behalf of the owner, verify the power of attorney carefully, including whether it is registered and still valid. Transactions via power of attorney need extra caution.
15. Builder-buyer agreement (for new projects)
Review possession timelines, specifications, payment schedule, penalties and cancellation terms. See checklist before buying a flat.
16. Allotment letter and payment receipts
For new projects, keep the allotment letter and all payment receipts safely.
17. Identity verification of the seller
Verify the seller's identity documents and, where multiple owners exist, ensure all owners consent and sign.
Practical tips
- Get a lawyer: A qualified property lawyer can conduct title search and due diligence. The fee is small compared with the risk.
- Visit government offices or portals: Verify records independently.
- Check physically: Ensure boundaries and area match documents. Use the site visit checklist.
- Never rely only on photocopies: Inspect originals before final payment.
- Keep copies organised: Store digital and physical copies safely.
Red flags
- Seller reluctant to show original documents.
- Missing occupancy certificate for a "ready" property.
- Unregistered agreements or unclear power of attorney.
- Disputes, pending litigation or unclear inheritance.
- Price far below market without a clear reason.
Key documents to review
| Document | Purpose |
|---|---|
| Title deed / sale deed | Proves ownership |
| Mother deed / chain of title | Shows ownership history |
| Encumbrance certificate | Confirms no registered loans or charges |
| Approved building plan | Confirms construction is sanctioned |
| RERA registration (new projects) | Confirms project registration |
| Occupancy / completion certificate | Confirms building is fit for occupation |
| Property tax receipts | Shows taxes are paid |
| Society NOC (resale) | Confirms no dues to the society |
| Allotment letter and builder-buyer agreement (new) | Defines terms of purchase |
Resale vs new property documents
For resale properties, focus on the chain of title, previous sale deeds, society NOCs, tax receipts and loan closure documents if the seller had a mortgage. For new projects, check RERA registration, approvals, builder-buyer agreement and the developer's land title.
Organising your documents
Keep originals in a safe place, scan everything and store digital copies securely. Maintain a list of documents with dates and reference numbers. This makes future sales, loans and legal processes far easier.
