You don't know who wrote it, you don't know how accurate they are, you don't know their source.
It is just a leaflet which may or may not have mistakes.
I already spot something very suspicious : that you must leave Thailand "for minimum one day". That seems to be incorrect, there is no minimum requirement mentioned in the original Thai law.
Also "after" 360 days is incorrect : that would be an overstay.
I added the clarification because many people will misunderstand it. So many don't understand even the basics on what the visa vs what the entry stamp is, visa on arrival vs exempt vs waiver, etc... (I didn't know either in my early years 5555) and even if it is clear for you, some will think they could get another 60 days out of it.
some clarification about that re-entry stamp : the visa was already used by entering Thailand, thus it would be impossible to re enter on the same visa.
But that 60 day entry stamp would have been kept "alive". And would have been possible to still use that 60 day entry stamp. This is an important distinction because when OP would have re-entered Thailand with a re-entry stamp they got afterwards, they would NOT have gotten another 60 days entry stamp, BUT only to the day the original entry stamp specifies. (The remainder of the days which was specified by the original enrry stamp)
So OP stayed 34 days, flew out and let's say about 6 days later flies back in, then there would have been only 20 days left to stay. Thus giving less days than a simple visa exempt.
It doesn't activate a new round of 60 days.
All of this because the distinction between what the visa actually is, and what the entry stamp actually is.
ok, then he only has to deal with the German laws regarding the will and inheritance tax, Thai laws are as good as irrelevant.
I'm not familiar with the details of these laws. But as in so many countries a handwritten will is legal in Germany if it conforms to certain specifications : handwritten and signed by the testator. The full name, the date it is written.
Inheritance tax depends on who inherits. For his wife it's tax-free for the first half million euros. No idea if his marriage is registered in Germany, and what steps to take if not.
If I were him, I would quickly write a will to have already something in case of emergency. And then contact a notary/lawyer to get all the details sorted out.
Sure he can make one himself, but since he is dying I would make sure every angle is covered by involving a notary.
Depends also if there are other siblings who might later contest whether he was sound of mind in case he writes it himself.
1) that happened. That's not an interpretation. The officer asked for an updated bank book and needed to see it the next day for stamps to be moved to the new passport.
2) It doesn't prove that during that whole period everything was done correctly. But it would be easily possible to catch SOME cases. Just 1 print below the threshold is all what is needed. The same as a quick look in a car or luggage : IF they find something, then it is proof. If they don't find anything, than it just proves they didn't find anything - nothing else.
It's an extremely low effort way to check.
But the logic doesn't even matter. All that matters is that now at least 1 or more officials have began to check it. Anyone who then has a bank book which doesn't meet the requirements will be in trouble.
