This thesis aims to address the begining of the legal personality of the person, and it advocates for the recognition of the unborn child as an despersonificated entity, which does not hold legal personality, but that the law itself treats it as if it were. In this context, the principle of human dignity identified as general clause of personal rights underlies the recognition of the unborn child as a subject of rights, because such principle is inherent in every human being, and in some cases, also not human beings. Thus, when understanding the principle of human dignity and personality rights applied to unborn, it discusses the theories that attempt to solve the problem of personality of this entity. Furthermore, by identifying the tutelage of personality rights such as the right to life, physical integrity, health, affiliation, adoption, moral damages, among others of the unborn, the law accompanied by the jurisprudence recognize the legal capacity of this entity. Therefore, when applying civil and constitutional hermeneutics from the principle of human dignity, it is possible to recognize the unborn child as a not personified subject of law that has rights and duties.
