This chapter specifies various legal causes for the acquisition of ownership, such as acquisition in good faith, rules for finding lost or buried objects, and the principle of accession. It highlights the Chinese Civil Code’s explicit recognition of the good-faith acquisition system for both movable and immovable property, while also noting areas for potential refinement. The chapter emphasizes the distinct Chinese approach to lost and buried property, which prioritizes returning items to owners or transferring them to the State, reflecting traditional moral values. Furthermore, it acknowledges the Code’s positive step in formally establishing rules for accession, thereby addressing practical needs in social life.
