Reader question: Contract for usufruct

Dear Jan,
for the usufruct on the land, it indeed has nothing to do with owning land, it is only for the use of the land and if a house has also been built on it, for continuing to live there after the death of your partner, but that does not give him any certainty if his girlfriend dies, the family will do everything they can to sell the land.
I have already heard that a Usufract in Thailand can be easily contested by taking legal action and then again who gets the short end of the stick.!? He does have 1 advantage with his son, if he is actually listed on the birth certificate as the father.!
I must also agree that a foreigner can indeed own land if you come across the bridge with enough money, that is also the only reason that you can also obtain Thai Nationality as a foreigner, with the big money everything is possible in Thailand. In connection with the statement that it will be even more difficult to obtain a usufruct on the land, I mention this because I know from an acquaintance that at the Pattaya land office the usufruct was refused by the chief officer, although he had purchased the Condo on name of his girlfriend they were not married for the Thai Government.
Adding the usufruct to a Thai is NEVER a problem, but giving a Falang the usufruct, when no legal marriage is involved, is apparently difficult for the chief officer to process.!
It took that person A LOT of effort and time to get this sorted through higher authorities in Bangkok and the reason was also because he was not married to his Thai partner.
The addition of a co-owner to the Chanote does indeed also cost normal
seen almost nothing, but to change the Chanote to a different name, (Donation) you do pay a registration fee, as I have already mentioned.
According to what I heard through third parties there could be an exemption or a reduction in registration costs, that would have to do with the years that you have already owned the property, but I'm not sure.
The reason I had the Chanote of the Condo in Pattaya transferred to my Thai wife's name, is so that no difficulties can arise if I die.
I also have a son in Belgium and if the title deed is in my name or both, my eldest son in Belgium can request his share of the estate on real estate in Thailand.
With my Thai wife I also have 2 children from our marriage, they will be 16 years old and 18 years old next year. If my wife dies before me, the house and the land (in the province of Sara Buri) will go to the children and with the usufruct at the Condo, I am safe until I die. That is why I have not had usufruct added to the Chanote of the house and the land.
I still live in Belgium for the moment and come to Thailand every 3 months with my family.
I planned to move to Thailand permanently from 2023, but I think it will get a bit faster with the corona problems, normally I come back to Thailand at the beginning of January and I think if there is no recovery in Europe with the virus , I will stay in Thailand permanently from next year.!
