My wife and I are in the process of doing this now. Now like most people should have done this a long time ago.
we have written our wills (hat tip Panda Munich) and will file them with the local court,
Anyways single friend mentioned setting up a Nachlassverwalter instead of a will. My understanding is that this is an executor who will settle your estate after your death.
So this brings up a question to which I haven't been able to find an answer to. We are childless and no family here. Since German wills (or we die intestate) don't have executor who settles the estate? House will need to be sold, Contracts cancelled and taxes filled and eventually money transferred. There is no way anyone in my family would have even a clue where to even begin. This is the reason I want to use an Nachlassverwalter.
Thanks in advance
