Article 1119
The parties to the marriage can stipulate any condition to the marriage which is not incompatible with the nature of the contract of marriage, either as part of the marriage contract or in another binding contract: for example, it can be stipulated that if the husband marries another wife or absents him self during a certain period, or discontinues the payment of cost of maintenance, or attempts the life of his wife or treats her so harshly that their life together becomes unbearable, the wife has the power, which she can also transfer to a third party by power of attorney to obtain a divorce herself after establishing in the court the fact that one of the foregoing alternatives has occurred and after the issue of a final judgment to that effect.
