GEN Gesellschaft für Erbenermittlung mbH would like to introduce itself

GEN Gesellschaft für Erbenermittlung mbH was founded in 1990 with nine employees – then under the name GEN Büro für Erbenermittlung GmbH. We now employ over 70 employees at our headquarters in Berlin, at our branches in Hamburg, Hanover, Cologne , Frankfurt am Main, Bayreuth and Stuttgart as well as at our subsidiaries in Gera, Poland, the Czech Republic and the USA. In addition, we have a worldwide network of correspondents and a special library collected through many years. The managing director is Jan-Mathis Holstein.

Our International Locations: Poland, the Czech Republic & the USA

We search for and locate heirs worldwide. When heirs who live abroad are searched for, we can fall back on our international locations:

Our subsidiary GEN Sp. z o.o. maintains offices in Słubice, Wrocław and Krakow from which we can conduct detailed on-location research without delay. Since the founding of our Czech subsidiary GEN Česko 2015, it has been locating heirs from its office in the capital city of Prague. The American section of our group of companies maintains an office on the east coast of the USA in Tampa. Since the founding of the American subsidiary AGHS (American Global Heir Search) in 2007, together we have earned an excellent reputation for the processing of AGHS (American Global Heir Search).

Our Strengths: Genealogical and Legal Expertise

Our competent team of highly-qualified genealogists consists of historians, attorneys, business economists, archivists and political scientists. With our many years’ experience and consistent commitment, we have dedicated ourselves to the interesting but also challenging work of locating heirs. Our strength is in our teamwork and specialized knowledge. Through the years our staff has continually been expanded with experts from diverse subject areas. Whether inheritance law, complex lines of succession or genealogical research abroad, our probate researchers fall back on their expertise while searching for unknown heirs. This makes it possible for us to independently correspond in over 20 languages and to solve seemingly hopeless cases.

Our legal department regularly writes a newsletter containing current information regarding inheritance law. We offer this to estate administrators, judicial officers and the general public as a download.

This month is the 30th anniversary of the founding of our company. Our genealogists in now 13 offices in four countries search for and locate heirs – GEN Gesellschaft für Erbenermittlung continues to develop even after three decades. This could – and can – only be done with the combined strength, reciprocal trust and great commitment of every individual. Without our teams in Germany, Poland, the Czech Republic and the USA, the company’s success would not be possible. And so we would like to take this occasion as an opportunity to express our thanks. We would also like to thank our longtime business partners for the trust they have placed in us. At the same time, we are happy to convince the estate administrators who do not know us as well of our quick and thorough working methods. In times in which change becomes normality, we will continue to be a reliable partner, working for our collective success.
