what is stakeholder ? sorry for being a noob here .
what happen if defect liability period is over but  the workmanship problem like wall begins to crack and cement fell off from the wall, leaking etc..

Check my earlier post:-

the Vendor's solicitors shall release such costs from such sum to the Purchaser within fourteen (14) days after receipt by the Vendor's solicitors of the Purchaser's written demand.
Yup you can pay your contractor first or make an arrangement with your contractor to remit payment after you're reimbursed. See lah how you nego with your contractor
