De iure patronatus liber singularis
Paulus, On the Right of Patronage. Patrons and their children have no right to the property of their surviving freedmen, unless they prove to the court that they are so weak or poor that they should be assisted with monthly contributions of food by their freedmen. This rule has been established by many Imperial Constitutions.
The Same, On the Right of Patronage. A patron should not be heard if he demands services which the age of the freedman does not permit, or the weakness of his body cannot endure, or by the performance of which his condition, or mode of life will be injuriously affected.
Paulus, On the Right of Patronage. Where a freedwoman, who has two or more patrons, marries with the consent of one of them, the other will continue to have the right to her services.
