Is construction helper insurance necessary for new builds - experiences?

The difference is that a move is done in one day. We ourselves had the experience that the BG employees were out weekly in the new development area and conducted inspections; with us, the luck was that it was built turnkey, so he was only there once for the inspection.

Help me out please. I received the letter from the BG today. What do they want from me? We are building with individual contracts and don’t lift a finger. No one has to help either. I don’t feel like filling out the form. It also doesn’t seem to be mandatory based on the wording. After all, the trades are also insured.

If a relative carries out a trade free of charge, he is not insured. It is important to report this. Who wouldn't want to never be happy again in their life if that is not insured?

Ok. No one will do anything. Everyone is 500 km away. So not necessary!?

Counter question: did you have this issue with any previous move when someone helped you with painting? Germany, nation of the overinsured...

Yes. Information mandatory. Name all trades you already know. You will receive this form several more times.
But actually, everything is stated on the form.

Please write it clearly. I can't make any sense of it ;)

Ok. If it has to be.
