Refund of life time maintainence at time of selling

SIR ,
MY UNCLE BROUGHT A FLAT 8 TO 9  YEARS BACK IN MAHARASHTRA. AT THE TIME PURCHASING UNCLE PAID EXTRA 20,000/-FOR LIFE TIME MAINTAINENCE ( THAT MEANS HE NEED NOT TO PAY ANY MAINTAINENCE EVER )
NOT ONLY HIM BUT EVERY 32 MEMBERS OF SOCIETY PAID . THAT 20,000/-( 20,000 * 32 = 6,40,000 ) AS SAVED IN SOCIETY FUND IN BANK AS FIXED DEPOSIT .

NOW HE WANTS TO SELL HIS FLAT - BUT MY QUESTION IS :-

1) DO WE GET BACK THAT 20,000/-( THAT IS OUR SHARE )  FROM SOCIETY FUND ?
2) OR SHOULD WE CHARGE EXTRA 20,000/- FROM PURCHASER AT TIME OF SELLING ?

THANKS

( ANSWER IN DETAILS AND SEQUENCEWISE PLEASE)
