The dissolution of the matrimonial bond ' in favorem fidei' is a relatively new canonical institute to dissolve a legitimate, non-sacramental marriage in favor of faith. The study examines and comments on the development of the institute during the 20th century. It focuses on the substantial and procedural norms to complete the process for the dissolution of the matrimonial bond in favor of the faith on the diocesan level. The first norms were promulgated in 1934, the second revised version in 1973, and the latest norms in 2001. The historical-canonical analysis of the institute shows that the dissolution of marriage should not diminish the value of indissolubility of marriage but offer a solution of difficult pastoral situations in favor of the faith or for the good of the souls.
