What is a relative
A relative is a term used to refer to a family member, either by blood or affinity. It is common for people to have close relatives, such as parents, siblings, grandparents, uncles and cousins, but they can also have more distant relatives, such as nephews, brothers-in-law and great-grandparents.
Kinship by blood
Blood kinship is kinship that unites people through a genetic relationship. This means that relatives by father and mother share genetic material, which makes them biologically closer. This bond is fundamental for the formation of the family and for the transmission of genetic characteristics from one generation to the next.
Kinship by affinity
Kinship by affinity, on the other hand, is that which unites people through marriage or other forms of legal union. In this case, relatives by affinity have no genetic ties, but are considered part of the family due to marriage or cohabitation. This includes parents-in-law, sons-in-law, daughters-in-law and brothers-in-law.
Kinship by blood
Consanguineous kinship is kinship that unites people through a common ancestor. This means that blood relatives share a direct ancestor, such as a father, mother, grandfather or grandmother. This link is fundamental for forming the family tree and for identifying relatives in different generations.
Civil relationship
Já o parentesco civil é aquele que une as pessoas através de uma relação legal, como a adoção ou o reconhecimento de paternidade. Nesse caso, os parentes civis não possuem laços genéticos, mas são considerados parte da família devido a uma decisão judicial ou a um ato de vontade. Isso inclui os children adotivos, os enteados e os sobrinhos por afinidade.
Relationship by degree
Kinship by degree is a way of classifying relatives according to how close they are. This means that first-degree relatives are the closest, such as parents, siblings and children, while second-degree relatives are more distant, such as uncles, cousins and nephews. This classification is important for determining the rights and duties of relatives in relation to each other.
Kinship by affinity
Kinship by affinity of inheritance is that which unites people through hereditary succession. This means that relatives by affinity are entitled to inherit each other's assets and property, in accordance with the law. This link is fundamental for the transmission of assets from one generation to the next and for the preservation of family ties.
Kinship by affinity by marriage
Kinship by affinity by marriage is that which unites people through the marriage of one of the spouses. This means that relatives by affinity by marriage are considered part of the spouse's family, even if they have no genetic ties. This link is important for integration and harmonious coexistence between the families involved.
Kinship by affinity through stable union
Kinship by affinity by stable union is that which unites people through a relationship of lasting and public cohabitation, without the formalization of marriage. This means that relatives by affinity by stable union are considered part of the partner's family, even if they have no genetic ties. This link is important for guaranteeing the rights and duties of cohabitants under the law.
