The present investigation provided scientific and legal knowledge, where the regulation of shared tenure within the Ecuadorian legal system was analyzed, since maternal as well as paternal rights may be violated, in order to ensure the best interests of children, girls and adolescents when there are separations between parents. For its study, a type of descriptive research was applied with field and documentary design. The interview and survey techniques were used, the results of which allowed to determine in what percentage the rights of children and adolescents have been violated. The results evidenced the need for a preliminary draft of reform to article 118 of the Code of the Childhood and the Adolescence on the shared possession, after the dissolution of the matrimonial bond, to safeguard the rights of the children who are in the stage of the childhood and adolescence. In conclusion, it is necessary to examine the social and psychological effects on children after the dissolution of the marriage bond, because it is the beginning of a range of breaches of children's rights, since in the phase of separation in most of the cases parents only seek their welfare without thinking about children and adolescents, to this is added the application of the law regarding the custody of children. 2023 24 31 2186 https://creativecommons.org/licenses/by/4.0/ 10.54216/JSPR.030103 https://www.americaspg.com/journal/26/article/2186 https://www.americaspg.com/storage/61698316034.pdf
