Marriage is an alliance between a man and a woman, a community of love and life that the Creator founded. The basic element of marriage is consent that manifests itself between legally competent persons who cannot be replaced by any human authority. Furthermore, the paper explains who the persons with disabilities are, how many and what their damages are, how disability affects the lives of these people and their families. It is necessary to understand how people with disabilities need faith and unity in which they will find a spiritual atmosphere to solve their spiritual and physical needs. Therefore, it is considered which person with disabilities is allowed and who is not allowed to join the sacrament of marriage. That is why it is necessary to establish the degree of disability as well as the necessary mental rationality and mental state when speaking of canonical law. While on the other hand, there is a civic marriage, and according to the family law, marriage can be concluded by all persons who are capable of business, that is, they cannot make a marriage for those who are completely deprived of their professional capacity. According to family law, barriers to marriage are business incapacity, and in the Canon law Code, such a situation may call into question the understanding and understanding of the marital consent, which is the most important element in the conclusion of the sacrament of marriage. That is why it is necessary that persons who are deprived of their professional capacity obtain permission from the court to enter into a civil marriage, in which it is proven that they are aware of the facts of marriage, and thus may enter into a religious marriage.
