What to Check Before Booking a Flat from a Builder: Legal Checklist Every Buyer Must Follow

Booking a flat—especially in an under-construction or newly launched project—is a big step for any property buyer or investor. While glossy brochures, virtual tours, and builder promises may look appealing, failing to conduct a legal due diligence check before booking can result in financial losses, stalled projects, or court battles.

At KHA ADVOCATES, we help buyers—especially first-timers and NRIs—safeguard their investments with comprehensive legal support. This guide lays out a legal checklist to follow before you pay that booking amount.


1. Check if the Builder is RERA Registered


Why it matters:

Under the Real Estate (Regulation and Development) Act, 2016, all builders must register their residential projects (above a certain size) with RERA.


What to verify:

  • RERA Registration Number

  • Project details on your state’s RERA website

  • Completion timeline and approvals


Tip: Visit https://rera.gov.in and cross-check project details.

📌 KHA Tip: We verify RERA registration and flag any discrepancies before you invest.


2. Verify Title of the Land


Why it matters:

The builder must legally own or have development rights over the land. If the land title is disputed or not clear, the entire project becomes risky.


What to verify:

  • Title Deed and Ownership Chain (30-year verification)

  • Encumbrance Certificate (EC)

  • Lease/Development Agreements (if applicable)


📌 KHA Tip: We conduct deep title verification and provide certified legal title reports.


3. Check Project Approvals & Sanctions


Why it matters:

Without proper municipal and environmental approvals, the builder may face demolition or delay orders. You risk losing time and money.


Key approvals to verify:

  • Commencement Certificate (CC)

  • Building Plan Sanction by local authority

  • Environmental Clearance (for large projects)

  • Fire Safety and Airport NOC (if applicable)


📌 KHA Tip: We inspect all sanctions and compare them with construction on-ground.


4. Examine the Allotment Letter & Builder-Buyer Agreement


Why it matters:

These are legally binding documents that define your rights, timelines, penalties, and possession terms.


Watch for:

  • Clause on delivery date and delay penalties

  • Force majeure clauses

  • Escalation charges or hidden costs

  • Refund/termination terms


📌 KHA Tip: We negotiate the Builder-Buyer Agreement and protect you from one-sided terms.


5. Understand the Carpet Area Clauses


Why it matters:

Builders often quote “super built-up area” to appear cheaper. But you only own the carpet area.


Legal point:

RERA mandates disclosure of carpet area and its definition.


What to check:

  • Clearly mentioned carpet area

  • Loading % (difference between super built-up and carpet)

  • Agreement mentions area escalation clauses?


📌 KHA Tip: We break down the loading percentage and explain your actual usable space.


6. Check for Litigations & Pending Cases


Why it matters:

Even a high-profile project can have pending disputes or litigation that stalls completion.


How to check:

  • Builder’s litigation history (via High Court/SC portals)

  • RERA complaints

  • Consumer forum or NCLT disputes


📌 KHA Tip: We do background checks on builders across legal portals and flag red zones.


7. Verify the Builder’s Previous Projects


Why it matters:

Past delivery record speaks volumes about future reliability.


Things to verify:

  • Completion history

  • Quality of construction

  • Delay frequency

  • Consumer complaints


📌 KHA Tip: We verify past project delivery and check for blacklisted builders.


8. Check Home Loan Pre-Approvals (If Any)


Why it matters:

If reputed banks have approved loans for the project, it signals that due diligence has been done. Still, it’s not foolproof.


Check for:

  • Which banks have approved the project

  • Loan eligibility terms

  • Loan-to-value ratio offered


📌 KHA Tip: We independently verify bank clearance and help you secure home loans at best rates.


9. Ensure GST, Stamp Duty, and Tax Implications Are Clear


Why it matters:

Tax liabilities, if not properly calculated, can spike your cost by lakhs.


What to check:

  • GST applicable for under-construction flats (usually 5% without ITC)

  • Stamp duty & registration charges

  • TDS (1%) if value exceeds ₹50 lakh


📌 KHA Tip: We help optimize your property taxes and legally reduce stamp duty wherever possible.


10. Review Possession Timeline & Completion Certificate


Why it matters:

You must legally take possession only after receiving the Occupancy Certificate (OC) or Completion Certificate (CC).


Ensure:

  • Delivery date is not vague

  • Compensation clause for delay

  • Final handover includes OC and NOC from authorities


📌 KHA Tip: We ensure legal handover, post-registration compliance, and verify builder’s obligations.


🚨 Never Pay in Cash or Unaccounted Payments


Why it matters:

Any cash transaction is illegal and non-defendable in court. Always insist on full transparency.


📌 KHA Tip: We ensure all payments are through legal channels and documented properly.
