What are the Documents to Check Before Buying a Flat in Bangalore
Learn flat document verification in Bangalore, with documents to check before buying a flat, RERA, sale deed, khata, EC, OC, CC, tax, and loan records.
Quick Summary: (TL; DR)
Before buying a flat in Bangalore, verify key documents like the sale deed, title chain, Encumbrance Certificate (EC), Khata, RERA registration, Occupancy Certificate (OC), Completion Certificate (CC), tax receipts, approved building plan, and loan records. Proper document verification helps avoid fraud, ownership disputes, legal issues, and future problems during registration, resale, or home loan approval.
What Is Flat Document Verification?
Flat document verification refers to the process of verifying the legality, ownership, permissions, taxes, and approvals for the project and flat prior to its purchase.
This facilitates the answers to the following questions:
• Is the vendor authorized to sell?
• Is the project approved?
• Is the flat covered by RERA, if applicable?
• Are there any mortgages or litigation involved?
• Are khata, tax, and title documents in order?
The significance of document verification in Bangalore is even higher due to involvement of builders, resale vendors, apartment committees, BBMP/GBA, BDA layout plans, RERA, and loan approvals from banks.
Why Flat Document Verification Matters in Bangalore
Bangalore property deals often involve many layers of documents.
A flat may look ready for sale, but the document trail may still have issues such as:
• Missing occupancy certificate
• Mismatch in flat number
• Unpaid property tax
• Pending home loan
• Wrong khata details
• Unregistered project
• Title gap in previous sale deeds
• Deviation from sanctioned plan
These issues can affect registration, loan approval, future resale, and ownership confidence.
What are the Documents to Verify Before Buying a Flat
Here is the main checklist.
Document | Why it matters |
Sale deed | Shows current ownership transfer |
Mother deed / title chain | Shows ownership history |
Encumbrance certificate | Shows registered transactions or charges |
Khata certificate and extract | Shows municipal property record |
Property tax receipts | Shows tax payment status |
RERA registration | Confirms project registration where applicable |
Sanctioned building plan | Shows approved construction |
Completion certificate | Shows construction completion as per approval |
Occupancy certificate | Shows building is fit for occupation |
Building approval / commencement certificate | Shows permission to begin construction |
Joint development agreement, if any | Important in builder-owner projects |
Power of attorney, if used | Confirms authority of person signing |
Loan closure/NOC, if mortgaged | Confirms bank charge is cleared |
Apartment association documents | Useful for maintenance and common area details |
1. Sale Deed
The sale deed is the key ownership document.
For resale flats, check whether the seller's name appears correctly in the latest registered sale deed. Also check flat number, floor, undivided share of land, schedule, parking rights, and registration details.
Do not rely only on a photocopy. Ask for the registered document details and compare them with other records.

2. Mother Deed and Title Chain
The mother deed or title chain shows how ownership moved over time.
For apartments, this may include land-owner documents, development agreement, builder sale deed, earlier resale deeds, partition deeds, gift deeds, or inheritance documents.
The goal is to see whether the seller's ownership has a clean path from earlier owners.
3. Encumbrance Certificate
An encumbrance certificate, or EC, shows registered transactions affecting the property for a selected period.
It can reveal sale deeds, mortgages, releases, and other registered entries. In Karnataka, EC-related services are available through Kaveri Online Services.

4. RERA Registration
For under-construction or applicable projects, check whether the project is registered on Karnataka RERA.
On the RERA portal, buyers can check project registration, promoter details, project status, uploaded documents, approvals, and complaints where available.

5. Khata Certificate and Khata Extract
Khata documents show the municipal property record.
For Bangalore flats, check whether the property falls under BBMP/GBA, BDA, or another local authority. The khata details should match the flat, property tax, and ownership record.
BBMP/GBA e-khata services are available through the e-Aasthi route.

6. Property Tax Receipts
Ask for the latest property tax paid receipt.
Check:
• Owner name
• Property ID or PID
• Assessment year
• Tax paid status
• Built-up area
• Usage type
• Arrears, if any
Unpaid tax can create problems during khata transfer, resale, and due diligence.
7. Sanctioned Plan, OC and CC
The sanctioned plan shows what the authority approved.
Completion certificate, or CC, shows construction completion as per approval. Occupancy certificate, or OC, shows the building is fit for occupation.
For apartment buyers, OC is very important because it affects loan eligibility, utility connections, resale confidence, and legal compliance.
8. Home Loan and MODT Records
If the seller has a home loan, ask for:
• Loan outstanding letter
• Bank NOC
• Loan closure letter, if closed
• List of documents held by bank
• MODT or mortgage release records
The flat should not carry an uncleared mortgage after the sale.
How to Verify Flat Documents Online
Some checks can be done online.
Use:
• Karnataka RERA portal for project registration
• Kaveri Online Services for EC and registered document services
• BBMP e-Aasthi for e-khata status

Online verification is useful, but it should be combined with document review.
