If the Landlord's name is not the same as on both the deeds and rental contract, there are further complications! My neighbour's rental agreement was with the Landlord's sister...(his 'agent') & a copy of her ID card, house docs and power of attorney, etc and she signed the rental agreement. Phuket immigration also wanted to see a power of attorney from the brother to the sister, or a direct rental agreement between the owner and the renter. It's getting very complicated in Phuket!
