Article II. On the Subject of Contract

I say. By natural law all and only those can contract who have free use of reason, because these alone can transfer dominion of goods and undertake obligations. But by positive law, besides the use of reason and free will of contracting, it is also required that the contracting party have free disposition of goods, and not be declared by law incapable of making a contract. Moreover, by positive law the following are incapable of contracting, at least in many things or validly: 1st, minors; 2nd, wives; 3rd, the civilly dead; 4th, the interdicted and prodigals; 5th, aliens. A few things concerning each.
