Refund of advance paid

Sir as per agreement terms condition builder can deduct it from paid amount and paid back remaing amount to you.

Will u give THANKS on my LCI profile for free advice?

my query is whether builder can deduct on the total cost of flat or only on the amount already paid?

As per agreement it is 10% of the cost of the flat and not the 10% of the amount so far deposited.

But even 10% of the cost of the flat will be a large chunk of amount. For example, if the cost of the flat is Rs. 1 crores then the building will deduct Rs. 10 lacs (i.e. 10% of the total cost of flat). This is highhandedness on the part of the buiding. I am sure there must be some govt. rule as to how much amount of penalty if the purchaser cancels the agreement to purchase the flat. I think this can be known the Municipal Corporation of that area.
