If you have been contacted by us

If you have been contacted by us as an heir or heiress, this almost always comes as a complete surprise and understandably raises many questions. We would like to answer these questions as transparently as possible. If we are unable to do so here on the website, please do not hesitate to contact us personally or visit us at our locations in Berlin and Cologne.

Investigation of heirs for guardians of estates

It is not at all uncommon for a person to die in Germany and for the heirs to be unknown. If there are no close relatives, the probate court gives inheritance cases with an "estate in need of security" to so-called estate administrators. They are often successful in their search for the heirs. If this is not successful, then we can help as heir searchers.

News from the inheritance investigation

In our daily work, we frequently come across special cases, which we regularly report on our website. The same applies to news about us and our employees - be it awards for our work or reports about our pro bono activities.
