then you may need a lawyer to fix it all up for you. Certainly possible, just how much hassle is unclear.
It sounds like yes very much you can do what you want, buy property in your child's name and live in thailand. You'll be doing yearly extensions to a visa and 90 day reports and all that, and you can't sell or mortgage the property... but you can do it I think
it kind of sounds like if the mother is there to give conscent you don't need a court even if the child is an infant... but then again, it's Thailand it's probably up to the particular office and officer you visit? Who knows... i'd ask a couple lawyers.
Yes i think you're right, and also it's possible that as long as the marriage was registered that might actually be enough... at least according to chatgpt. It gets stuff wrong a lot but it still knows more than me about this subject. Obviously you want legal council on this I would think... anyway
and again none of this matters until you are recognized legally as the child's father in Thailand.. and since you were not married at birth, you need a lawyer to fix that
yes this is exactly correct. If you were not married when the child was born you must use the Thai court system to become the recognized father legally in Thailand.
As for owning land this may actually be possible depending on the law, which I am not an expert in. Consult with a good attorney and this might be possible. You can probably gift the child money, and if you are a legal guardian of his estate then perhaps you can buy land for him? I don't know it's an interesting question actually I'd love to know more.
yes there are other places that are better than Thailand in some ways. For example, Canada has better snow skiing. But on balance Thailand is the best place in the world. The Thai people are the best people in the world.
Paying attention to your visa and not fucking it up is a basic form of respect you should show to the Thai people.
