Ulpianus, On the Duties of the Prætor Having Jurisdiction Over Guardianships. The administration of three guardianships offers a good excuse. Three guardianships are understood to mean, not that the number of wards give rise to distinct guardianships, but that the estates are separate and distinct. Hence, where a guardian is appointed for three brothers who are entitled to an undivided estate, or where a guardian is appointed for two of them, and a curator for the others, he is held to have undertaken but one guardianship.

Ulpianus, On the Duties of the Prætor Having Jurisdiction Over Guardianships. It is sufficient that the parties charged with three guardianships should belong to the same family. Hence, if the father, the son, or the brother of anyone who is under the same control, is charged with the administration of three guardianships, the father will be responsible for the reason that they are administered with his consent. This will be a good excuse for all of them to be released from any other guardianship. Where, however, they do not administer the trusts with the consent of the father, it has been frequently stated in rescripts that this will not be available as an excuse.
