After his death, Schatzi took it out of the drawer and asked for a certificate of inheritance. As Schatzi was easily identifiable as a person, the will was written very briefly but signed in full by hand, she was recognised as the sole heir (Oldenburg Higher Regional Court, decision of 20.12.2023, ref. 3 W 96/23).
The formal requirements for a handwritten will are roughly the same in Germany and Italy, but as Italians are generally more fond of form than Germans, it is at least questionable whether an Italian court would have ruled the same way.
