[ULPIANUS libro uicesimo sexto ad Sabinum. ] §23.2.9.prSi nepos uxorem uelit ducere auo furente, omnimodo patris auctoritas erit necessaria: sed si pater furit, auus sapiat, sufficit aui uoluntas.
[ULPIANUS in the twenty-sixth book on Sabinus.] If a grandson wishes to marry when his grandfather is insane, the authority of his father will be necessary in every way; but if his father is insane and his grandfather is sane, the consent of the grandfather is sufficient.
§23.2.9.1Is cuius pater ab hostibus captus est, si non intra triennium reuertatur, uxorem ducere potest.
He whose father has been captured by enemies can marry, if the father does not return within three years.
