La thèse porte sur l'évolution des normes parentales dans des situations où celles-ci sont discutées, mises en jeu et légitimées, en particulier concernant la pluriparentalité. D'une part, je me suis penchée sur le projet légal de "parenté sociale" qui vise à reconnaître la place et les droits d'un adulte qui s'occupe de l'enfant de son conjoint avec qui il n'a pas de lien biologique. D'autre part, j'ai analysé des situations familiales dites de "coparentalité" où gay(s) et lesbienne(s) s'associent pour avoir un enfant ensemble en l'élevant séparément. The PhD thesis deals with the evolution of parental norms in changing situations in which these norms can be discussed and modified, specifically en terms of multiparenthood. On the one hand, I have studied a new form of legal status - “social parenthood” - debated in the Belgian Parliament to recognize non-biological parenthood. On the other hand, I have analyzed gay and lesbian “coparenting”, which can be defined as a parental project involving a lesbian woman/couple and a gay man/couple brought together to have a child and raise he or she separately. In each case, I examined the ways in which individuals live and deal with familial situations that involve same-sex couples and/or more than two parents raising a child.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The present thesis examined the family ways of life and descent after changes in the demographic behaviors in Brazil. The dominant family model composed of a couple and their children coexists today with an increase in diversified family arrangements. Because of these transformations, the family sociology has turned to the plurality of norms that constitute the families, these having in mind their relevance in many discussions in the field of Social Sciences. Understanding that the alliance is not the only way to establish a descent, it is proposed to explain how blood, law and coexistence are articulated in descent institution. Hence, the discussions that permeate the work sessions broached families, descents and their meanings in the current theoretical, legal and current social framework. The basic idea of this work is that, depending on family dynamics, other adults appear to contribute or even care for children / young people and, in these situations, there is the possibility of multi-parenting happens, overlapping the feelings of parenthood. The methods used were the analysis of quantitative data, interviews with sons who experienced multiple parenting and the investigation of paternity / maternity cases from the Sergipe Court of Justice (TJ / SE). The notions of descent, capable of dissociating reproduction and descent, revealed that blood has the force of law, coexistence creates moral duties, and the use of terminology of kinship differs from feelings. / Notre thèse a examiné les modes de la vie familiale et la filiation après les changements de comportements démographiques au Brésil. Le modèle familial dominant composé d’un couple et de leurs enfants coexiste aujourd’hui avec une diversité d’arrangements familiaux. Ces transformations ont fait que la sociologie de la famille s’est tournée vers la pluralité des normes qui constituent les familles, compte tenu de leur pertinence dans les diverses discussions dans le domaine des sciences sociales. L’alliance n’étant pas le seul moyen de fonder une filiation, nous proposons d’expliquer comment le sang, la loi et la coexistence s’articulent pour les filiations. Dans ce contexte, les sessions de travail ont porté sur des familles, des filiations et leurs véritables significations dans le cadre théorique, juridique et social actuel. L’idée principale de ce travail est que, selon la dynamique de la famille, d’autres adultes contribuent ou même prennent soin des enfants/jeunes, pouvant, dans ces situations être de la pluriparentalité, en superposant les sentiments de filiation. Les méthodes utilisées ont été l’analyse de données quantitatives, des entretiens avec des enfants vivant avec plusieurs parents et l’enquête sur des décisions de paternité/maternité de la Cour de justice de Sergipe (TJ/SE). Les notions de filiation, capables de dissocier la reproduction et la filiation, ont révélé que le sang a force de loi, que la coexistence crée des devoirs moraux et que l’usage de la terminologie de la parenté diffère des sentiments. / A presente tese examinou os modos de vida familiar e a filiação após as alterações nos comportamentos demográficos no Brasil. O modelo dominante da família composta por um casal e seus filhos coexiste hoje com um aumento de arranjos familiares diversificados. Por estas transformações, a sociologia da família voltou-se para a pluralidade de normas que constituem as famílias, tendo em vista a sua pertinência nas várias discussões no campo das Ciências Sociais. Ao entender que a aliança não é a única forma de instituir uma filiação, propõe-se explicar como se articulam o sangue, o direito e a convivência na instituição das filiações. Neste sentido, as discussões que permeiam as sessões do trabalho abordaram as famílias, as filiações e suas acepções no quadro teórico, legal e social atual. A ideia norte do trabalho é a de que, a depender das dinâmicas familiares, outros adultos surgem para contribuir ou mesmo cuidar das crianças/jovens, e nestas situações, existe a possibilidade da pluriparentalidade acontecer, sobrepondo os sentimentos de filiação. Os dispositivos metodológicos utilizados foram a análise de dados quantitativos, entrevistas com filhos que vivenciaram pluriparentalidade e a investigação de acórdãos sobre casos de paternidade/maternidade do Tribunal de Justiça de Sergipe (TJ/SE). As noções de filiação, capazes de dissociar reprodução e filiação, revelaram que o sangue tem força de lei, a convivência cria deveres morais e o uso de terminologias do parentesco difere dos sentimentos. / São Cristóvão, SE
