My wife has a small house which is leased out, with what i understand to be a standard lease (one month's rent up front and two months rent as deposit). Rent is due to be paid on Monday, but the tenant informed my wife yesterday that they wanted to move out in 18 days time. I think that it is most unlikely that any rent will be paid on Monday, and as there are months left on the lease, I don't think that any refund of deposit will be due, however my wife (forever Thai), says that we have to refund the balance of the deposit. What is actually the correct procedure here in Thailand?
