This two-volume study, the result of extensive research conducted in France over four years, focuses exclusively on the wife. The first study in its field, it sheds light on the capacity of the wife's unilateral will to break the marriage in two different legal systems, secular and religious. It also opens up a completely new debate on the subject, dealing with the margin of freedom granted to the wife in these two systems. The comparison is made between two women, one subject to French secular law and the other to Islamic law applied in Arab countries drawing its foundations from religious sources. The study aims at discovering which system gives more freedom for the rupture by analyzing the modes of divorce that each system proposes to the wife. The research, which is based on two hypotheses of rupture, without and with determined cause, also deals with the questions still presented before the French justice. The jurists and all those interested in the subject will find a work rich in various doctrinal positions, legislative texts and judicial decisions translated from Arabic for the first time.
