The Powers and Duties of Tutors
The duties of the tutor with respect to the care and management of the child's property were substantially those of an English trustee. Generally, he was required to administer the property of the pupillus as a prudent man would do, and if in consequence of the tutor's deliberate disregard of duty (dolus), or want of due diligence (culpa lata aut levis) the pupillus suffered loss or failed to gain an advantage that could, with due diligence, have been obtained for him, the tutor must make good the loss. And the tutor could not be released from responsibility even by an express clause in the will appointing him, for the tutela was a public office, the duties of which could not be modified by private arrangements.
A child under the age of puberty possessed very little legal capacity, even though sui juris in the sense of not being under power. He could not bind himself by contract, and there were some legal transactions, as acquiring an inheritance, which even though they might be wholly beneficial to him, required the authority of a tutor to be effective.
The child, even though he had no property, had need of a tutor to supply the requisite legal force to certain juristic acts. And while still an infans, that is, before he had completed his seventh year, the child could not bind himself by contract, even with his tutor's authority.
The general rule was that a child over seven and under the age of puberty might better his condition, even without the authority of his tutor, but he could not make it worse without such authority. Thus in contracts creating obligations on both sides, such as sales, letting to hire, or deposit, if the tutor did not give his authority, those contracting with the child were bound, but the child was not in turn bound to them. No pupillus of either sex could dispose of any of his property without the tutor's authority, though property could be conveyed to pupils of either sex without such authority.
In certain cases, even though for his own benefit, the pupil could not act without the consent of his tutor. Thus he could not, without his tutor's authority enter on an inheritance, demand the possession of goods, or accept an inheritance by way of trust, even though such act was advantageous to him and involved no chance of loss. Ordinarily, however, the assistance of the tutor was required only where the effect of the act was to alienate property or to impose a liability.
But although a pupil could not bind himself by contract to a third person without the consent of his tutor, this rule was subject to certain equitable restrictions in favor of the other party. The pupil could not keep what he had bought and refuse payment, nor demand back what he had sold without returning the purchase money.
The consent of the tutor to the transaction was required to be given at the time of the transaction, but was not necessarily in any particular form. In giving or withholding his consent the tutor was bound to act solely with a view to the advantage of the pupil, and to act with due prudence.
If he gave his consent improperly he was responsible to the pupil for any resulting loss. If the child was still infans (under seven) the tutor acted on behalf of the child (exercising the right of gestio), but if the child was over seven, the child himself acted, with the assistance of the tutor.
In giving his consent the tutor was not regarded as making the contract for the child ; the child was regarded as the contracting party, but he was not bound by the contract unless the tutor consented. Actions brought by or against a pupil under seven were brought or defended by the tvitor in his own name; but if the pupil was over seven the suit was brought or defended in the pupil's name with the tutor's consent.
