House on parents' property - inheritance problems?

It will still take some effort for my father...

He has now, after three days of reflection, realized that the proposed solution is too far-reaching for him. He does not want to be content with a right of residence in his house. So we are now considering two more options. One is the physical partition [Realteilung] (where it is important to him that I neither rent out nor sell my house) and the other is a solution in which all real estate assets are divided equally between him, his wife (my mother), and me. Of course, this is the most expensive solution in terms of the value of the matter. However, we will also seek tax advice beforehand. In principle, he still does not believe that the lawyer and notary are advising us correctly. Ideally, he would prefer if everything remains as it is...

He would actually prefer if everything stayed the way it is...

Did he understand WHAT that means to you negatively?

He does not see the need for care as a real problem because both have a good pension, insurances are in place, and other assets are also available. As far as inheritance tax is concerned, we are quite in the dark because we cannot precisely estimate how the tax office will assess my house (or, for that matter, the house I live in and have paid for). The rest is also difficult because it involves agricultural and forestry land, and we are not sure how that will be assessed, meaning whether the market value or the replacement economic value will be used.

whereby it is important for him that I may neither rent out nor sell my house

Hmm, difficult if it's that set in stone. What is the reason, what is he afraid of? What does your mother say? How does she want the problem to be solved?

Well, he is afraid of losing control, that's clear. Besides, he has spent his entire life on this property. Nothing happens here without him. My mother would be much more relaxed about it, but she only moved in here 50 years ago...
