Return of sale agreement document

Dear Kams,

while entering into Sale Agreement the market value of the property will be shown, whereas at the time of execution of Sale Deed for the same property only guide line value in the jurisdictional sub-registrar will be considered. What you have paid as guide line value will be white money and the difference between the value shown in the Sale Agreement and Sale Deed will be black money.  In order to conceal the black money your developer is demanding to return the original sale agreement.  It is normal procedure to return the sale agreement or destroy the sale agreement after the execution  of Sale deed in your favour.  If you want for your reference you can make a copy of the same and keepit with you and therewill not be any repercussions.  I hope you understood the situation.
