Bought a house but absolutely no idea about the subject

TE acquired the house for a purchase price of 115K + the father's right of residence registered in the land register.

That the 115K€ then only went to the mother, he doesn’t have to care about that, that really is a divorce issue of the parents.

No no no, it doesn't have to be that simple or even that way.

Possibly the TE only bought the mother's ideal half, then there would be no registered right of residence at all.

From how everything reads here, a lot is vague and in my opinion, some things just don’t work that way.
In the end, it is always two different things: the one who pays and the one who gets the bill. That seems a bit mixed up here and is not seen very clearly...

That is not ill will towards the father,

But you do get the feeling that the son, that is you dear TE, was made a plaything – as long as the parents come out clean.

My advice: gather everything together, go to some help and organize it. Then: where is the journey supposed to go and with whom? What must and what can be done (-> land register)
Concrete solutions and defined statements, of course also towards the father.
You are not responsible for your parents!
Be careful not to let the tasks overwhelm you. You have to get moving yourself.

You do get the feeling, though, that the son, meaning you dear OP, has been made a pawn - the main thing being that the parents come out fine.

Then a bit clearer and without beating around the bush:

what has been outlined here (according to the OP's statement, right of residence for the entire house in the land register) is top-notch nonsense for the OP. I would probably still try to reason with them (slyly ;-) ) first rather than immediately going into open confrontation.

Unfortunately, I’m not really familiar with rights of residence. Does anyone have any idea whether the father with a right of residence for the whole house could actually evict the son, since the son is the owner but the right of residence presumably covers the sole right of use (=whole house)?
I might also ask a notary about that, if necessary.

That’s what I meant with the statement that the notary has to make clear what the situation actually is. Or the original poster didn’t listen. No idea. If the right of residence is not limited to something specific, it applies in my opinion to the whole house – and I find that serious or rather an absolute no-go: Something like that must also be clearly pointed out by the notary to the "disadvantaged" party (here the original poster). If not, he simply hasn’t done his job. But all just speculation: None of us were there......

The die is cast

the Dropps is sucked

Whereas the role of the notary in this case would still be quite interesting....
