A person between the age at which pupillarity ceases (fourteen in boys, twelve in girls), and majority. Minors in trade are liable for trading debts, and all minors are liable to perform their contracts, unless they can prove lesion, i.e., damage arising from the contract, in which case they may be relieved against it within four years after majority, a period called the quadriennium utile. But in no case will they be relieved against a debt contracted for value, except in so far as both parties can be restored. Minors without curators (guardians) may contract as validly as minors who have curators, and whose curators give their consent. Such consent does not validate an injurious contract.
