ADD HOLSTEIN opens office in Innsbruck, Austria

The identification of unknown heirs knows no national borders. Of course, this sentence is not really true. Rather, one could say that the needs of heir tracing take no account of current borders.

By establishing a subsidiary in Austria, we are meeting these needs.

We ourselves find our work exciting, otherwise we wouldn't be passionate heir hunters. We can always tell that other people also find our work interesting when the media report on our activities. The current issue of the Frankfurter Allgemeine Sonntagszeitung newspaper reports in detail on ADD HOLSTEIN Erbenermittlung and our work. It also features an heiress who had no idea that there were other relatives in her family and an estate curator whose work is at least as exciting as ours. We are very grateful that the relatively unknown field of heir tracing is becoming a little better known in this way.
