Romans viewed ''res mancipi'' as that property of particular importance to them, at least in early Rome. Gaius (Institutes 2.14a - 2.22) explains the difference between the two categories of property by giving example of what constitutes ''res mancipi'' and ''res nec mancipi''.<ref name="Gaius">{{cite book |last=De Zulueta |first=Francis |url=https://books.google.com/books?id=27AqAAAAYAAJ |title=The Institutes of Gaius |publisher=OUP |year=1946 |isbn=0-19-825112-2 }}</ref><ref name="Gaius (online)">{{cite web |title=The Institutes of Gaius |url=http://thelatinlibrary.com/law/gaius.html |url-status=live |archive-url=https://web.archive.org/web/20210709182512/http://thelatinlibrary.com/law/gaius.html |archive-date=July 9, 2021 |accessdate=23 March 2012 |publisher=thelatinlibrary.com}}</ref> He tells us that lands and houses on Italic soil, beasts of burden, slaves, and rustic and praedial servitudes are all ''res mancipi''. Gaius goes on to say that ''res mancipi'' may only be conveyed formally, that is either by the ''mancipatio'' ceremony, or ''in iure cessio''.
The distinction between ''res mancipi'' and ''res nec mancipi'' was formally abolished by Justinian in Corpus Juris Civilis.<ref>{{Cite book |url=https://lawblogsa.files.wordpress.com/2014/10/foundations_notes.pdf |title=Derivative methods of acquisition of ownership |year=2014 |pages=1–72 |archive-url=https://web.archive.org/web/20210709183110/https://lawblogsa.files.wordpress.com/2014/10/foundations_notes.pdf |archive-date=July 9, 2021 |url-status=live}}</ref>
