🔍 Why Are Property Documents So Important?

Imagine buying a beautiful house, shifting in with your family, and then one day receiving a legal notice claiming you’re not the rightful owner. Scary, right?

This happens when buyers skip verifying property documents. These papers:

• Legally transfer ownership to you

• Prove that the seller has the right to sell the property

• Help in getting home loans

• Prevent disputes in the future

• Ensure government records are updated in your name

Without them, you may lose the property, face legal troubles, or be cheated in a fake deal.

✅ The 5 Most Important Documents You Must Check

Let’s go step-by-step through the top five documents that you must demand and verify before making any purchase decision.

---

1️⃣ Sale Deed (Title Deed) – The Final Proof of Ownership

The Sale Deed is the most essential document in any property transaction. It is the legal proof that the seller has transferred the ownership of the property to you.

What It Must Include:

• Names of buyer and seller

• Full property description

• Agreed sale amount

• Date and signatures of both parties

• Registration number and stamp duty details

The Sale Deed must be registered with the Sub-Registrar of the area. Only a registered deed is considered legal in the court of law.

💡 Tip: Ask for the original Sale Deed and check whether the seller is the rightful owner.

2️⃣ Possession Letter – When the Property Is Handed Over

This document is issued by the builder or seller to confirm that the property has been physically handed over to the buyer.

Why It’s Needed:

• Proves that possession was given on a certain date

• Important for bank loan processing

• Acts as proof for claiming your right to occupy the property

However, remember that possession is not ownership unless you have a registered Sale Deed and Occupancy Certificate.

---

3️⃣ Mutation Certificate (Entry in Revenue Records)

Mutation means the updating of government land or property records in your name after purchase. It’s also called “Dakhil-Kharij” in many Indian states.

What It Does:

• Updates property tax and revenue records in your name

• Useful for future sale of property

• Especially important in rural and panchayat areas

It is issued by the local municipality or village authority.

🛑 Without mutation, taxes may still be in the name of the previous owner, causing legal confusion.

---

4️⃣ Occupancy Certificate (OC) – Permission to Stay

The Occupancy Certificate is issued by the local development authority or municipal body. It declares that the building is:

• Constructed according to approved plans

• Safe to live in

• Ready for occupancy

Why OC is a Must:

• Required for electricity, water, and gas connections

• Without it, your stay can be considered illegal

• Also required for getting a completion certificate

If a builder doesn’t give the OC, you can take legal action.

---

5️⃣ No Objection Certificates (NOC) – Clearance from Government Departments

When a developer starts a project, they need to obtain several NOCs from different government departments. These approvals are proof that the project is not violating any law.

Examples of NOCs:

• Fire department

• Pollution control board

• Airport Authority

• Electricity board

• Water supply department

• Local panchayat or municipality

Depending on the city, a project may require up to 19 NOCs.

✅ Always ask your builder for copies of these NOCs before signing any agreement.

📑 Other Important Documents to Check

While the five documents above are critical, there are several supporting documents that also play a major role.

---

📄 Allotment Letter

For newly built or under-construction projects, the allotment letter is issued by the developer. It contains:

• Property details (unit number, size)

• Payment plan

• Date of possession

• Amount paid and balance

It’s important for home loan applications and is usually issued after booking the property.

---

📄 Property Tax Receipts

Always check if the previous owner has paid all property taxes. This avoids any unpaid dues landing on your head.

What to Verify:

• Receipts for last 3–5 years

• Owner’s name on the receipt

• Property ID matches the current unit

---

📄 Encumbrance Certificate (EC)

This certificate ensures that the property is free from legal and financial liabilities like loans or court cases.

You can get it from the Sub-Registrar’s Office. It shows transaction history of the property for up to 30 years.

---

📄 Mortgage Documents (If Home Loan Taken)

If you take a home loan, the bank will create a mortgage document stating that the property is collateral until you repay the loan.

After full repayment, ensure:

• You get a loan closure certificate

• The bank removes the mortgage from government records

---

📄 Building Plan Sanction Letter

If the building plan is not approved, it may be illegal construction. Check for the sanctioned building plan approved by local authorities.

---
