There is a lot of corruption in Thailand. I guess if the land office was in on it, a forgery is possible. I know people get desperate if they hit bottom.
My name is on the chanote. It’s my understanding that we both need to be present and sign at the land office during a sale. Which I do not plan on doing.
I have heard horror stories of the farang being harassed by his ex wife, her family, and her friends after a divorce. Building a house in another village may be a good idea. Instead of in her village next door to her brother.
I think renting vs buying depends on your age, financial situation, how much time you can spend in Thailand, etc. I paid 400,000 baht for a small piece of land in Chiang Rai when I was 42 years old. I have spent about 15 months there in the past 2 years. Probably not a smart move for a 70 year old. Covid19 keeps me away now but I don’t feel like it was a loss of money.
I think it depends on the land office. I have a lifetime lease registered at the Chiang Rai land office. My name is on the chanote. The way I understand it, the land cannot be sold unless me and the owner sign.
