Thank you Sir(s) for your response. I think Society has no role to play because some amount is due from Builder directly to me. This is towards some corpus amount as promised in the agreement.
So let's say corpus of 2 Lakh was agreed. Now builder has paid only 1.5 L and now the possession letter says something like I agree that there are no outstanding dues from the builder.
So the question is should I sign it because does my signature on that document gives scope to builder to point out that now there are no dues, and legally weakens by claim even though the cheques desposited are only for 1.5 Lakh. Builder might fake and say I gave you cash!!
Other members have to pay some amount to builder, I don't have to, so what they are going to do is negotiate and deduct the dues from the payment they will be making to builder. That's their plan. I don't fall in that category.
As far as my understanding goes every builder puts these lines in the possession letter. They even say that member (i.e. I ) have verified the carpet are and is satisfied and is found to be correct.
