House on parents' property - inheritance problems?

I certainly do not understand why I could only gain this knowledge after 20 years. Every cigarette pack says that smoking is unhealthy. And every little child really knows that. But on the building application back then, under "Bauen auf fremdem Grund," there was nothing like "Warning, this will transfer ownership of the house to the owner of the land." Which ordinary citizen is supposed to come up with such an idea? I certainly have no desire to pay inheritance tax on my self-paid house as well. I am against any form of wealth taxes anyway.

Which ordinary person would come up with such an idea?

Which ordinary person comes up with the idea of building their house on someone else's land? But why am I even writing this? I think is right.

But why shouldn't I have done that? Even my grandparents specifically left the space open so that something could be built there again. I actually think it's sensational that I was already able to do that in my mid-20s. And in your mid-20s, you can't know everything yet. It's actually logical, isn't it?

What is there really to investigate afterwards?

In your mid-20s you are legally an adult, but too young in life experience for many things. At that age, consumption and enjoyment are the focus. The chance of owning a house (consumption) has blinded you. Besides, you probably blindly relied on your parents and didn’t take care of it yourself.

I certainly have no desire to pay inheritance tax on my self-paid house. I am against any form of wealth taxes anyway.

What does the state care about what you want? Regardless of whether you reject various taxes or even the entire legal system, it applies:
Ignorantia legis non excusat.

Enough complaining, now I want to contribute something constructive:

The inheritance case that is being worked on here is the much smaller risk. Much more dangerous is the already mentioned and ignored case of needing care. Your house is not occupied by you as the owner. [..]
But there is indeed the risk that your house must be sold to pay for nursing home costs.

You could have a right of residence registered in the land register. Then you are protected. The right of residence also significantly reduces the value of the property, so the inheritance tax may be lowered. However, your tax advisor should be able to explain which figures are used to assess the tax. In case of doubt, the rear property could also first be sold to cover nursing home costs.

The rear property cannot be developed, so it is probably not marketable either. I will start looking for a suitable lawyer/notary and/or tax advisor.

In any case, I have not the slightest desire to pay inheritance tax on my self-paid house. I am against any form of substance taxes anyway.

We have understood that by now. Nevertheless, your whining does not help.

No one told us that the house would then not belong to me.

Ignorance does not protect against foolishness. Some basic knowledge you have to acquire yourself. That was possible in the past as well.

maybe done differently. No non-lawyer would come up with such an idea.

When you then look at the land register... or give someone a gift, you know that paying and ownership are not always assignable to the same person.

I actually find it sensational that this was already possible for me in my mid-20s. And in your mid-20s you can’t know everything yet. That’s actually logical, isn’t it?

It may be that your parents bought you, but you do not automatically belong to them. Fits, right?
