Documents to Check Before Buying a House or Flat in India
Buyer due-diligence checklist for a house or flat in India: title chain, encumbrance, RERA, approvals, OC/CC, tax dues, society records, and red flags.
Quick answer
EstimateBefore buying a house or flat, check the seller's title chain, encumbrance record, RERA registration where applicable, approved plan, completion/occupancy certificate for ready property, property-tax and utility dues, society NOC, and loan-closure/NOC if the property was mortgaged. These checks reduce risk but do not guarantee title; get local legal review before paying a large token or signing.

Buyer Due-Diligence Checklist
| Document | What to check | What it does not prove |
|---|---|---|
| Registered sale deed/title chain | Whether ownership transfers are traceable | That there is no hidden dispute |
| Encumbrance certificate/search | Whether registered claims or mortgages appear | Unregistered claims or family disputes |
| RERA project record | Registration and project disclosures where applicable | Quality, completion certainty, or clear title |
| Approved plan and layout | Whether construction matches approvals | Future regularisation or completion |
| Occupancy/completion certificate | Whether ready property has completion approval | That every internal alteration is approved |
| Property-tax and utility receipts | Whether visible dues are pending | That all society or legal dues are settled |
| Society/builder NOC | Transfer process and dues status | Title validity |
| Loan closure/NOC | Whether an old mortgage is cleared | Any unrelated title defect |
Red Flags
- Seller avoids sharing the full title chain before token payment.
- Ready-to-move flat has no occupancy certificate.
- RERA number, tower, carpet area, or possession details do not match the state portal.
- Property is still mortgaged but there is no lender NOC or closure plan.
Official Verification Sources
Use the relevant state RERA portal via the Ministry of Housing and Urban Affairs RERA gateway, and state land-record/registration portals where available. State data differs, so local legal review matters.
