Sorry, somehow the above post got messed up and was probably printed anyway, so I started again.
This is a nasty jumble that cannot be unraveled all at once.
The law does not look the same everywhere as it does with us, and there are regions where it is treated more as a recommendation and the decisiveness and initiative of an individual are seen more positively than here. Still, facts whose creation one initially allowed become difficult to impossible to undo.
That causes hurt feelings. The question would be, if there are now emotional and factual problems, whether one could more easily defuse the two conflict areas by addressing them one after the other.
Professionally, in condominium management I often have to train people who have a completely different idea of ownership. By the way, it is tedious and does not always work. Sometimes we have to enforce it legally, then the defeated party is hardly moved to feel a sense of belonging. But it does often work when a mediator can be found whom both sides appreciate.
What might a mediator be like?
He, in this case unfortunately a woman can be forgotten, could for example be familiar with the mentality where there is suspected to be more hurt feelings. He could be a specialist where the factual problem solving is more pressing. With such a search grid, one could go out and try to win someone over.
I have very bad experiences when something is allowed that does not work and one wants to sue it away later. Better not.
Many greetings and my sympathy,
Gabriele
