Treaties involving enemies are illegal and are not enforced by the court. The agreements declared contrary to public order by the courts are as follows: it is an agreement in which one or the other party or third party receives a certain amount of money in return for the marriage. Such agreements, which are in favour of public order, are inexigable. Example: A, a father of a girl promised to give a certain amount of money to B, a father of a minor boy and B agreed to marry his minor son with A`s daughter. . . .
