Legal representatives of legal persons under private law and incorporated partnerships (§ 20 Para. 1 GwG), trustees and custodians (§ 21 Para. 1 and 2 GwG) are obligated to immediately disclose their beneficial owners in the Transparency Register, unless such beneficial owners are already evident via other public registers (e.g. commercial register). Listed companies are excluded from seperate notifications to the Transparency Register provided that the controlling position arises out of appropriate notifications of major holdings.
Required data for beneficial owners include: first name and surname, date of birth, domicile, type of beneficial owner (fictitious or actual) and the nature and extent of the commercial interest (§ 19 Para. 1 GwG). Changes of data of the beneficial owner over time and information that in the meantime the beneficial owner (again) is evident from other registers are obligatory.
