A more thorough explanation:

PROFECTITIUM PECULIUM

Profictitium peculium is a term used in Roman law to describe the property that a father allowed his son to manage and use while the father retained ownership. This property was given to the son while he was still under the father's control.

An example of profectitium peculium would be a father giving his son a small farm to manage and use for his own benefit. The son would be responsible for the day-to-day operations of the farm, but the father would still retain ownership of the land and any profits made from it.

Another example would be a father giving his son a sum of money to invest in a business. The son would be responsible for managing the investment and any profits made from it, but the father would still retain ownership of the initial sum of money.

Profictitium peculium was a way for fathers to give their sons some independence and responsibility while still maintaining control over their property. The son was allowed to manage and use the property for his own benefit, but the father would still retain ownership and control over it. This helped to ensure that the property remained within the family and was not lost or misused.
