A more thorough explanation:

MANCIPI RES

Manicipi res refers to property in Roman law, specifically Italic land with its rustic servitudes and beasts of draft or burden, that can only be transferred by a formal ceremony of mancipation. It is also known as res mancipi or things mancipi.

Examples of mancipi res include:

• Land in Italy with its accompanying servitudes and draft animals
• Slaves
• Oxen and horses used for farming

These examples illustrate the definition of mancipi res because they are all types of property that can only be transferred through a formal ceremony of mancipation. This means that the transfer of ownership must be done in a specific way, with witnesses and a set of formal words, in order for it to be legally recognized.
