SOGENI, a leading Swiss firm in probate genealogy and heir search
Our core activity: probate genealogy
Genealogy: a science at the service of legal professions and financial institutions
The “probate genealogist”, more commonly known as the “heir hunter”, undertakes to search for the heirs called upon to collect estates that have remained vacant or partially settled.
In this respect, he enables the authorities and representatives responsible for such estates to carry out their task, since Swiss law requires that all heirs be sought by all possible means before settling an estate.
At the same time, he makes it possible for the heirs found to assert their right to an inheritance of which they would never have known without his intervention.
Thanks to his research skills, the probate genealogist also assists financial institutions or administrations in finding the beneficiaries or owners of assets with whom contact has been lost.
The probate genealogist: a passionate scientist with multiple skills
In addition, the probate genealogist must have the scientific rigor required to deliver with certainty his conclusions regarding parentage and the hereditary rights that flow from it.
often with international ramifications. Thus, the mastery of foreign languages is crucial for the latter.
Finally, advanced skills in computer tools and databases have become crucial for contemporary probate genealogists.
