It is intended to analyze and reflect in the present work about the institution of the extension of parental authority and parental authority rehabilitated in the new regulation in the Draft Law that reforms the civil and procedural legislation to support people with disabilities in the exercise of their legal capacity. In this project, the extended parental authority and the rehabilitated parental authority are eliminated from the scope of disability, following a criterion that demands the treatment of people with disabilities with the attention that their specific situation requires, eliminating a regime that seems contrary to the system of promoting the autonomy of adults with disabilities. This study is linked and addressed, with the characteristics and needs of people with a severe intellectual disability, as they will be affected by the reform and by the effect of the structural deficiencies suffered by the Justice system of our country. the present work about the institution of the extension of parental authority and parental authority rehabilitated in the new regulation in the Bill of Law that reforms the civil and procedural legislation to support people with disabilities in the exercise of its legal capacity.
