Hello , what in case the seller is local UAE , and is delaying the process of giving the liability letter for the further process of transfer and not supporting in overall deal and trying to back out by saying he is going to be traveling and not available for 2 months and does not want to do POA, but MOU EXPIRES by the time he is back and even buyers offer letter from bank expires as well, in that case can a buyer still ask for help from DLD ?
