5 Documents Every Flat Buyer Must Check
Before Signing – Don't Skip These!

Why Document Verification Matters

Buying a flat is likely the biggest financial decision of your life. Yet thousands of buyers in India face legal disputes every year simply because they skipped proper document verification. A beautiful flat means nothing if the paperwork is flawed — you could lose both the property and your money.

Before you sign any agreement or hand over a token amount, make sure these five documents are thoroughly verified by a qualified legal professional.

1. Title Deed (Sale Deed of the Land)

The title deed proves who legally owns the land on which your apartment is being built. It traces the ownership history and confirms the seller or developer has the legal right to sell the property.

What to check: Ensure the chain of ownership is clear for at least 30 years. Look for any gaps in succession, pending litigation, or disputes. The title should be free from any mortgage or lien. Ask your lawyer to conduct a title search at the Sub-Registrar's office.

Red flag: If the developer hesitates to share this document or if there are multiple owners without clear consent from all parties.

2. Encumbrance Certificate (EC)

An Encumbrance Certificate confirms that the property is free from any monetary or legal liabilities. It shows all transactions registered against the property over a specific period, including mortgages, loans, and liens.

What to check: Obtain the EC for the last 15–30 years from the Sub-Registrar's office. Verify there are no outstanding loans against the land. In Telangana, you can now apply for EC online through the IGRS portal.

Red flag: Any undisclosed mortgages or pending cases that appear on the certificate.

3. RERA Registration Certificate

Under the Real Estate (Regulation and Development) Act, 2016, every residential project with more than 8 units or land exceeding 500 sq. meters must be registered with the state RERA authority. In Telangana, this is TS-RERA.

What to check: Verify the RERA registration number on the official TS-RERA website. Check the project completion timeline, carpet area details, and whether the developer has disclosed all required information. Confirm the project hasn't been flagged for any violations.

Red flag: Projects marketed without a RERA number, or developers who claim "RERA applied" without showing proof of registration.

4. Approved Building Plan

This is the construction plan sanctioned by the local development authority — GHMC, HMDA, or the respective municipality. It confirms the building design complies with local zoning laws, setback rules, and floor space index (FSI) regulations.

What to check: Match the approved plan with the actual construction. Verify the number of floors, total units, parking allocation, and common areas match what's been sanctioned. Ensure the plan hasn't expired and no deviations have been made.

Red flag: Additional floors or units beyond what the approved plan shows — this means unauthorized construction that could face demolition orders.

5. Commencement Certificate

Also known as a construction permission letter, this document authorizes the developer to begin construction on the approved plan. Without this, any construction is technically illegal regardless of other approvals.

What to check: Confirm the commencement certificate is issued by the competent authority and matches the approved building plan. Check the validity period and whether construction started within the permitted timeline.

Red flag: Construction that began before this certificate was obtained, or a certificate that doesn't match the current building plan.

Bonus: Additional Documents to Request

Beyond these five essential documents, also ask for the land use conversion certificate (if applicable), NOCs from fire, water, and electricity departments, and the occupancy certificate (for ready-to-move projects). For resale flats, request the previous sale deeds, society NOC, and latest maintenance receipts.

Final Advice for Hyderabad Buyers

Never rely solely on the builder's word. Hire an independent property lawyer to verify all documents. In Hyderabad's fast-growing market, especially in areas with recent land-use changes, title disputes are more common than you'd expect. Spending ₹5,000–₹10,000 on legal verification can save you from a ₹50 lakh mistake.
