With the Real Estate (Regulation and Development) Act (RERA) now firmly established, homebuyers are more cautious than ever about parking their hard-earned savings in under-construction projects. Constant construction delays have undermined confidence in some under-construction ventures, and demand for ready-to-move apartments has climbed steadily as a result — but the paperwork rigour applies to both categories.
After paying the token amount for a property, the real documentation process begins. Most buyers feel overwhelmed at this point, unsure which papers matter, which are optional and what each document actually protects them against. Below is a clear checklist of the essential documents you need to verify before buying a home — whether you’re looking at flats in Hyderabad or any other city.
Essential Documents to Check Before Buying a Home
Agreement of Sale
This contract sets out the crucial specifics of the deal — property description, payment terms, completion deadlines, the form and amount of the fee, and the consequences if either party fails to honour the agreement. The agreement of sale is a legal document signed between buyer and seller confirming that both sides have settled on the terms of the transaction.
Occupancy Certificate
For ready-to-move-in properties, the municipal corporation or planning authority issues an Occupancy Certificate (OC) once construction is complete. It’s one of the most important documents on any property checklist — the OC legally states that the building complies with the approved layout and is fit and safe to be occupied. Never move into a property without a valid OC in hand.
Sale Deed
The Sale Deed is the core legal document containing proof of the sale and the formal transfer of property from the developer or seller to the buyer. Many years after purchase, the Sale Deed remains the single most important record of ownership — so keep the original safely and register it at the local sub-registrar’s office without delay.
Allotment Letter
Not every developer issues an allotment letter, but it’s always worth having if offered — especially when you’re booking a home that’s still under construction. The allotment letter spells out the price of the unit, any additional costs for services or add-ons, and the payment schedule. It’s also essential when you’re applying for a home loan, because the bank uses it to confirm the amount the purchaser is committed to pay.
RERA Approval and RERA Registration Number
Since the Real Estate Regulation Act (RERA) came into force, strict penalty provisions combined with sharper homebuyer awareness have pushed developers to focus on timely project delivery. Before you commit, check the RERA Telangana website and verify the project’s registration number. You’ll find approval details, construction status updates and any complaints filed against the developer — all of which reshape how you negotiate.
Documents for Land Approval
Before construction begins, the developer is expected to obtain the requisite permissions from the relevant land and planning authorities. Ask for copies of the approved building plan, layout approval from HMDA, NOC from the fire department and clearances from utility providers. Missing land-approval documents is one of the single biggest red flags in a property purchase.
Bank APF Number
The Approved Project Financial (APF) number is issued by banks to projects they’ve cleared for home loan lending. If a project has an APF number from a major bank, it means the bank has done its own due diligence on land title and construction approvals. Always ask the developer for the list of banks that have issued APF numbers for the project — it’s a practical shortcut to verify the project’s paperwork is in order.
Buying a property is the closest thing to a dream-come-true for most families — but it doesn’t take much for a dream to go wrong if the paperwork isn’t watertight. Knowing exactly which documents to verify, whether it’s a ready property or one under construction, is what separates a confident buyer from an anxious one.

Frequently Asked Questions
What documents should you verify before buying a home?
Essential documents include the title deed establishing ownership, encumbrance certificate showing the property is free of legal dues, approved building plan from local authorities, RERA registration certificate, completion and occupancy certificates, property tax receipts, and NOC from relevant authorities if applicable.
What is an encumbrance certificate and why is it important?
An encumbrance certificate is a document from the sub-registrar office that confirms a property has no pending legal dues, mortgages, or litigation for a specified period. It is critical because it proves the property has a clear title and can be legally transferred. Banks require it for home loan approval.
How do you verify if a property has a clear title?
Verify by obtaining the title deed chain for at least 30 years, checking the encumbrance certificate for the same period, confirming there are no pending litigation cases, verifying the property boundaries match revenue records, and consulting a property lawyer to review all documents before finalizing the purchase.
