Ulpianus, On the Lex Julia et Papia, Book II. Where a freedwoman is living in concubinage with her patron, she can leave him without his consent, and unite with another man, either in matrimony or in concubinage. I think, however, that a concubine should not have the right to marry if she leaves her patron without his consent, since it is more honorable for a freedwoman to be the concubine of a patron than to become the mother of a family. 1I hold with Atilicinus, that only those women who are not disgraced by such a connection can be kept in concubinage without the fear of committing a crime. 2Where a man keeps in concubinage a woman who has been convicted of adultery, I do not think that the Lex Julia de Adulteriis will be applicable, although he will be liable if he should marry her. 3If a woman has lived in concubinage with her patron, and then maintains the same relation with his son or grandson, I do not think that she is acting properly, because a connection of this kind closely approaches one that is infamous, and therefore such scandalous conduct should be prohibited. 4It is clear that anyone can keep a concubine of any age unless she is less than twelve years old.

Ulpianus, On the Lex Julia et Papia, Book II. It is established that whenever an estate, or anything else, is acquired through some person who is under the control of another, it is immediately acquired by the latter, and does not remain for a moment vested in him by whom it is acquired, and hence it is directly obtained by the party entitled to it.

Ulpianus, On the Lex Julia et Papia, Book II. Anyone can very properly say that an estate which falls to a person as heir at law, or by will, legally belongs to him, because by the Law of the Twelve Tables testamentary estates are confirmed.
