The house we live in is a gem. So if sth. happens to my wife I can not inherit it but we want to register a 30 year lease at the land department.

Is there a minimum rent we need to agree to? Is 1 Baht/month possible? We want it to keep as low as possible since we are in the highest tax class and, in the end, it is just to protect myself from being kicked out if sth. happens my wife...

A lease would be useless ...

Since you can't own land, it will have to be sold and or transferred out of wife's name within 1 year.

Suggest you have a POA drawn up, so you can sell said land within that year, and ensure all proceeds go to you. Since you are asking, you should consult a lawyer for further advice.

I think that in the scenario zappalot has outlined, he will be the lessee, his wife will be the lessor and the contingency that he wants to cover is the death of his wife - the death of the lessor.

yes, I am the lessee, my wife the lessor, sorry if my initial description was not exactly clear...

Since I am paying in advance for 30 years it would be surprising if I would be kicked out upon my wifes death.

I just fear tax would need to be paid on the determination of the value as set by the land department?

???

Of course you can inherit it.

You, as a foreigner, can inherit the land and the house in your own name.

Who told you that you can't, some guy at a bar? 🙄

After inheriting the land and house the foreigner has 12 months to sell or transfer it to a Thai, if you don't the land office can choose to sell it at auction and they keep 5% of the sale and transfer 95% to your bank account.
