Relevant regulations:

First, the generation of relatives can only be based on blood, marriage or legal fiction for three reasons. Kinship caused by marriage refers to the relationship between husband and wife formed by marriage between men and women, also known as spouse. As a result, parents, brothers and sisters, parents, brothers and sisters' in-laws came into being. Kinship is limited to natural consanguinity.

Relatives created by law. That is, based on some legal act or legal fact. The legally recognized subjects are relatives, such as adoptive parents and adopted sons. Stepparents and stepchildren born from upbringing are all regarded as fictitious blood relatives by China law.

Second, relatives have fixed identities and titles. After kinship comes into being, the kinship status and appellation between subjects are generally fixed, and the parties may not change or terminate it at will except in accordance with the law. The identity and appellation between relatives can be divided into two types from the perspective of the reasons for their formation and whether they can be changed or dissolved:

First, natural kinship or kinship formed by birth belongs to absolute and permanent kinship status and title. The parties cannot change;

Secondly, kinship and appellation based on marriage or law are relatively variable. In other words, these titles can be terminated by divorce or dissolution of the adoption relationship according to law. However, the parties shall not terminate the contract at will.

Third, the law recognizes that a certain range of relatives have rights and obligations with each other. As Engels said: "Parents, children, brothers, sisters and other titles are not simple honorary titles. But a completely certain responsibility. A very serious term of mutual obligation. The sum of these obligations constitutes a basic part of the social system of these ethnic groups. "
