The biggest stumbling block was "Numerator of the share belonging to the economic unit: numerator" and "...: denominator".
People, just write it down simply: Do you fully own the damn thing: Yes/No
If no: To what percentage:
Numerator and denominator, ugh...
The ownership shares are listed in the land register in fractions. You simply adopt them 1:1 like that.
I was more irritated by the numerator/denominator topic in the area of property designation because it is very simple for us (district 12, plot 123). However, especially in older properties, you often find plot numbers also in fractional form. This probably often occurs in condominiums as well.
Well, I had to look it up briefly.
