Hi there, appreciate if anyone here can explain to me about the timing on this stamp duty refund

when i sign the S&P 3 months back, my lawyer ask me to pay the full amount of stamp duty first and after if its got approve by the LHDN, he will refund to me the 50%. however, when i called him last week he told that i will have to wait for another one month to get the refund of 50 % on stamp duty.

As for the progress on the S&P process, last i check with the bank today they have confirm and will prepare the cheuqe for the last payment(balance purchase sum) to my loan lawyer, the cheque will be ready for collection tomorrow. So from here i assume by next week, i will be getting the key from the owner and complete the whole S&P process.

so my question is why next month? i assume i have done all the necesary process including stamping the deep of assigment, so why do i still need to wait for another month for the refund?

hopefully some one can explain to me the time line and who is involve in approving the refund here so i can have a more solid base before i go to my lawyer office next week, thanks
