The following analysis focuses on the study of matrimonial dispensations in Spain during the eighteenth and nineteenth centuries. The discourse on the part of the Church on consanguinity has been characterized by a strong restriction on the closest degrees of kinship. Matrimonial dispensations become a necessary practice for the regulation of kinship and consanguinity, which is interpreted as a way to correct forbidden alliances. The theory of impediments has a multiple dimension, in which the union of the flesh as a marriage prohibition begins to be distorted in the eighteenth century. The transgression of the norm and the transcendence towards the public sphere of this type of forbidden marriages reflects a socio-cultural and civilization change. The main cause of this change is manifested through the different agents of change, ranging from the Diocese to the highest spheres of the Church. We conducted a tour through the main Roman courts with the aim of knowing their evolution.
