FACTS:

Pingol  owned  a  parcel  of  land,  half  of  its  undivided  portion  he  sold Donasco.    Later,  the  land  was  separated  from  the  mother  lot.    Donasco died, leaving a large unpaid balance for the land.  The heirs filed an action for specific performance.  Pingol then was asking for a larger amount and didn't want to accept payment of balance.
 

HELD:

Although the complaint filed was an action for specific performance, it was actually an action to quiet title.  A cloud has been cast on the title.  Despite the  fact  that  title  has  been  conferred  to  them  through  the  sale,  the petitioners refused to receive the tender of payment being made by them.
