Back in 1987, my wife was not permitted to buy land as she was married to me. We had her father "buy" the land, and it was mortgaged to me for security, to prevent the family selling without my knowledge. Similarly at that time, our 2 year old daughter who was born in the UK, was not allowed to have Thai citizenship, as she was born outside Thailand. She had Permanent Residency, like me, and it was not until she was 17, that she was given Thai citizenship.
