What is specificatio in Roman law?

Specificatio is a legal concept from Roman law involving the creation of new property from materials belonging to someone else. It serves as an original mode of acquisition because it results in a completely new species of object, distinct from mere accession. Property law systems across various jurisdictions continue to grapple with these foundational doctrines of ownership and acquisition.
