Buying plot - original deed pledged

Since the Bank B has given NOC to Bank A means that Bank B is allowing the Bank A to realise the amounts in case of default by the plot owner on the properties pledged by the Builder.  If the Builder defaults his loan, the Bank B will realise the properties pledged by Builder. If you have not committed any default in making instalments and your payment is correct, your 45% amount will be safe.  Anyway I have to go through the Agreement/MOU between you, your builder and the original owner of the whole land of 400+ plots.  You contact me ravinder2345@gmail.com for further doubts. 

Hi Ravinder

"Since the Bank B has given NOC to Bank A means that Bank B is allowing the Bank A to realise the amounts in case of default by the plot owner on the properties pledged by the Builder.  "

this will safeguard only the 55% of the plot cost which is given as loan by Bank A

"If the Builder defaults his loan, the Bank B will realise the properties pledged by Builder."

in the above scenario, Bank B will allow Bank A to take the 55% it has given as loan to me

But remaining  45% (which is my money) is at risk. how to safeguard against that?

Since B Bank has taken the properties as pledge of more value than the loan,  Bank B has not hesitated to give NOC to Bank A. 

Here the point is the pledging of property documents is to safeguard the loan given by Banks A and B and not to safeguard your 45% advance amount.  

If the Bank commits any  voilations, you have to approach the Consumer court or civil court. 

i'm not able to understand the replies received. can anyone else please help clarifying.

Have you entered into sale agreement with the builder?, if yes, have you read the the conditions therein fully?, if yes, did you understand all the conditions and have you been satisfied with them before signing it?  If No to all the above questions, it is always better to take an opinion from your own lawyer in all the aspects including the doubts you have posted here so that you do not stand cheated at a later stage due to the gimmicks of the builder who you expect to trap you at a later stage.

Take an Indemnity Bond from the builder indemnifying legal liabilities to the extent of 55% loan amount. and get the same acknowledged by the  Banker.
