Great service and brilliant value for money. Will try and recommend you to as many of my friends as possible.
The process was very smooth and fast with very reasonable costs. I was able to register the Usufruct at the local land office without any problems.
My many thanks for all your assistance over the years and helping me navigate the Thai legal system, making sure all my property dealings were 100% legal.
