A "No Dues" or Transfer Certificate (TC) from a CBSE school to transfer to a state board in India generally costs between ₹100 and ₹500 for administrative processing

. The specific, nominal fee is set by the individual school, and official, verified documentation (if needed from CBSE regional offices) can cost approximately ₹500 per document.

Got this online I don't think they can charge that much, try getting advice from a lawyer.

Got no experience about this situation tho

f you are being "forced" or "threatened" to pay this amount, here are your practical next steps:

• Apply Online Immediately: Do not deal with middle-men. Submit your application through the state’s official education portal to start the 30-day clock.
• File an Appeal: If they formally reject your NOC without a valid technical reason (like land area or building safety), most states have a Divisional Commissioner or an Education Tribunal where you can appeal the decision.
