Klaas Zondervan (1981) owns a private law practice specializing in probate research and intestacy within The Netherlands and Belgium. Apart from being registered as a lawyer with the Dutch Organization of Legal Advisors (NVRA), he is also a licensed private investigator, focusing mainly on finding missing beneficiaries.
Because of lineage, he has an interest in Jewish genealogy and everything to do with World War II, particularly the Dutch resistance movements and war criminality. Although a probate genealogist by trade, he also conducts family research on many occassions. Feel free to contact him, should you find yourself in need of a professional genealogist.
