L Land plays an important role in the lives of society; therefore, every transfer of land rights requires regulations that ensure legal certainty. in indonesia, land sale and purchase and land registration are regulated under law number 5 of 1960 concerning basic agrarian principles and government regulation number 24 of 1997 concerning land registration, while in germany, they are regulated under the bürgerliches gesetzbuch (bgb) and the grundbuchordnung (gbo). this research examines the similarities and differences in the procedures for land sale and purchase in indonesia and germany, as well as the advantages and disadvantages of the systems applicable in both countries. the purpose of this research is to analyze the comparative regulations as a reference for the development of land law. the research employs a normative legal research method with a descriptive approach, using secondary data consisting of primary and secondary legal materials. the conclusions are drawn deductively. the results of the research indicate that indonesia and germany both require the involvement of public officials and the registration of transfers of land rights in order to ensure legal certainty. the difference lies in the publication system applied. indonesia adopts a negative publication system with positive tendencies, which makes the system more accessible to the public; however, the legal certainty provided is not absolute. in contrast, germany applies a positive publication system through the grundbuch, which provides a higher degree of legal certainty, although the process is more formal and entails greater costs. therefore, strengthening the elements of positive publication within indonesia’s land registration system may be considered as one possible direction for the reform of national land law.
