The house belongs to the bank, but they do not claim it, grandma lives in it

As far as I understand, the two gentlemen back then took out a large loan for their business idea. That then went downhill and the money was gone. For this, the bank wanted some securities, e.g. they had themselves registered in the land register for my grandma's house. But they apparently had other securities as well, probably with other people who were significantly wealthier. When everything was gone back then, they wanted to auction off our house, which was then successfully prevented twice. At the same time, they apparently also tried to recover their money from the other securities, which somehow presumably worked, which is why the bank waived the house. This is mostly speculation or assumption. None of us know exactly how it is and it will not be found out, since there has been no contact with my aunt's ex-husband since then and my aunt died of MS many years ago. Ultimately, we don't really care how exactly things were. The main thing is that the house is not gone. Regards Specki

Well then, no time to lose before the bank changes its mind!!! Get the statement aka "waiver declaration" from the bank in writing and off to the notary with it. Clear the land register as quickly as possible. Because with the registered guarantee, you can never sell the property or encumber it for renovation/new construction.

Exactly that is currently being set in motion
