Quick Summary: (TL; DR)

Before buying a flat in Bangalore, ensure that the sale deed, Khata certificate, Encumbrance Certificate , RERA registration, approved building plan, occupancy certificate, completion certificate, and latest property tax receipts are there before purchasing a flat in Bangalore. These documents confirm legal ownership, construction approval, loan eligibility, and smooth property registration in 2026.

What Documents Should You Check Before Buying a Flat in Bangalore?

Before purchasing a flat in Bangalore, you have to check title, approvals, tax records, and completion certificates. These documents confirm legal ownership, construction approval, and eligibility for registration and loans.

Below is a clear, step-by-step checklist used by banks, lawyers, and sub-registrar offices.

1.) Sale Deed: Proof of Legal Ownership

The Sale Deed confirms the legal ownership of the property as well as the right of the seller to sell it. The Sale Deed is the most important legal document in a flat purchase. It records the transfer of ownership from seller to buyer and must be registered at the Sub-Registrar Office.

What to check

• Seller’s name matches previous records
• Flat number, carpet area, and boundaries are accurate
• Stamp duty and registration are completed

Fact:
Banks insist on a minimum 30-year title chain through registered Sale Deeds before approving a home loan.

2.) Khata Certificate & Khata Extract (BBMP)

Khata confirms the property is recorded with BBMP for tax and civic purposes. A Khata Certificate and Extract show that the property is entered in BBMP records. While Khata does not prove ownership, it is essential for registration, loans, and utilities.

Types

• A Khata ✓ Eligible for registration and loans
• B Khata × Indicates regulatory issues

Data Point:
As of 2024, over 75% of bank loan rejections in Bangalore involve Khata-related issues (housing finance reports).

3.) Encumbrance Certificate (EC)

An EC confirms the property is free from loans, legal disputes, or charges. The Encumbrance Certificate lists all registered transactions related to the property.

What to verify

• EC period: Minimum 13 to 30 years
• No active loans or court attachments

Example:
If a builder has mortgaged land to a bank, it will appear in the EC until cleared.

4.) RERA Registration Certificate (Only for Apartments/Flats)

RERA registration ensures the project follows legal timelines and disclosure rules. All residential projects above 500 sq. m. must be registered under Karnataka RERA.

Check

• Project registration number
• Builder name and approvals
• Possession date

Stat:
Since RERA implementation, buyer complaints reduced by over 35% in regulated projects.

5.) Approved Building Plan (BBMP / BDA) (Only for Buildup Properties)

This plan confirms the building is constructed as per approved government drawings. Always compare the approved plan with the actual flat layout.

Red Flags

• Extra floors not shown in the plan
• Change in parking allocation

Unapproved deviations can block Occupancy Certificates and registrations.

6.) Occupancy Certificate (OC)

OC confirms the building is safe and legally fit for occupation. Issued after inspection by the local authority, the OC is mandatory for:

• Electricity connections
• Home loans
• Resale

Fact:
From 2023 onward, most banks will refuse loans for flats without OC in Bangalore.

7.) Building Completion Certificate (CC)

CC confirms the building is completed as per sanctioned plans. A CC is issued before the Occupancy Certificate and proves lawful construction.

8.) Property Tax Receipts

Tax receipts confirm there are no outstanding dues on the property.

Ask for:

• Latest BBMP tax paid receipts
• No arrears or penalties

Unpaid taxes can legally transfer to the buyer.

9.) No Objection Certificates (NOCs)

NOCs confirm compliance with utilities, fire safety, and environmental rules.

Common NOCs include:

• Fire Department
• BWSSB (Water)
• BESCOM (Electricity)
• Airport Authority (where applicable)

10.) Power of Attorney (If Applicable)

POA must be registered and valid if someone signs on behalf of the owner.

Always verify:

• Registration status
• Scope and validity
• Whether it allows sale rights

11.) Take an Expert Legal Opinion

For more clarity and security take a lawyer opinion.
