First of all, you need/must have a lawyer to see you through the purchase of any property in Thailand just so to make sure
that everything will be done right and correct, but by all means don't try to DYI, too many pitfalls,
Now, you can use a freelance lace lawyer that will will cost you a lot less than a swankey lawyer office, but 10 k will not get
a lawyer worth his/her time and efforts, i would say, depend on the circumstance, location and difficulties of processing
the purchase, around 50,000 baht would be a fair fee for a freelance lawyer...
