This is the published version of the first Maastricht Private Law Lecture which was delivered by Reinhard Zimmermann January 27th, 2017. According to a widely held view, the law of succession is shaped by the cultural values of the society within which it prevails. Related to this is the perception that the law of succession is marked by great stability. It is thus resistant both to change and to legal harmonization. Comparative research, too, has traditionally been regarded as impractical and unrewarding. In his lecture, Zimmermann challenges this view. He points to transsystemic constants as well as transsystemic tendencies of development, to outdated peculiarities and thinking patterns, as well as to the benefits to be gained by critical reflection, and he analyzes historical examples of the phenomenon of legal charge and the reception of rules and ideas. The focus is, throughout, on two central problem areas within the province of the law of succession: testamentary formalities and the intestate succession regime. Insofar as it obstructs or prevents a critical comparative discourse in this field, the "legal culture" thesis, according to Zimmermann, must be rejected.
