Generally speaking, the definition of the foster relationship of stepchildren can be started from the following aspects: the premise of the formation is the fact that stepchildren are underage and generally need to live together, and the fact that foster care lasts for a long time. The law does not specify what circumstances can be considered as "forming a relationship of upbringing and education", which is also controversial in theory. Those who meet the above conditions can be considered as having a dependency relationship.

First, the determination of the relationship between stepchildren.

1. The foster relationship of stepchildren is determined as follows:

(1) If a stepchild is underage and lives with one of his parents and his stepfather and stepmother, and the stepfather and stepmother bear part or all of the living and education expenses for him, or if an adult stepchild actually provides support and help to his stepparents for a long time, it is regarded as a dependency relationship;

(2) stepchildren live with their stepparents, who take care of and support their stepchildren in life; Or if they do not live with their step-parents, but the step-parents bear part or all of the living expenses and education expenses, it is regarded as a dependency relationship;

(3) Stepparents bear all or part of the living expenses and education expenses of stepchildren; Stepparents and minor stepchildren live together and take care of stepchildren in education and life. Even if it does not bear the maintenance expenses, it should be considered as a maintenance relationship.

2. Legal basis: Article 1072 of the Civil Code of People's Republic of China (PRC).

There should be no abuse or discrimination between stepparents and stepchildren.

The provisions of this law on the relationship between parents and children shall apply to the rights and obligations between stepfathers or stepmothers and their stepchildren.

Second, do stepchildren have the right to inherit?

The inheritance right between stepfather and mother depends on whether the foster care relationship is established;

1. If the stepparents have raised their stepchildren, the stepchildren have the right to inherit, otherwise they have no right to inherit;

2, parents remarried children have been married, usually have no inheritance rights, unless the parties have a will.
