It is the process of checking all documents related to legal, financial and technical issues of a property prior to purchase so that no disputes, risks, or hidden liabilities occur.

It protects the buyer from legal issues, ownership issues, unpaid property tax, building infractions, and loss of finances after buying.

A standard checklist will have title deeds, encumbrance certificate, tax receipts, sanctioned building plans, occupancy certificate, RERA approvals, and identity of the seller.

Ownership can be verified through the title deed, EC (Encumbrance Certificate) check, revenue records, and certified copies from the Sub-Registrar’s office.

An EC signed by the office of a Sub-Registrar and a search report by a property lawyer will indicate whether the property is under mortgage, attached by a court, or under dispute.

Key documents required are Sale Deed, Title Deed, EC, Khata or Patta certificate, approved building plan, property tax receipts, RERA registration details, occupancy certificate, and identity proofs.

Verify RERA registration, review previously delivered projects, check construction quality, confirm timelines, and read buyer reviews or complaints filed online.

Yes. In some states, EC, tax receipts, RERA status and parts of revenue records can be accessed online. A legal or technical expert should still review the findings.

It typically takes 15 to 30 days depending on document volume, property age, and whether legal or structural issues require deeper investigation.

A qualified property lawyer or legal documentation expert should handle legal due diligence. Technical checks are best done by architects, engineers, or valuers.

If issues like disputed ownership, missing approvals, or court attachments appear, the buyer should resolve them with the seller or walk away from the transaction.

Typical errors include ignoring original title documents, skipping EC verification, trusting builder claims blindly, overlooking RERA details, and missing property tax dues.

Legal due diligence checks ownership, approvals, litigation, and compliance. Technical due diligence assesses construction quality, structural safety, layout, and plan deviations.

Costs vary by property type and professional fees. Legal verification usually ranges from ₹5,000 to ₹25,000. Technical assessments cost more.

Basic online checks are possible, but professional verification is strongly recommended to avoid hidden legal or structural risks.
