Annulment of a marriage is an action that states that the marriage bond that has been entered into is invalid according to the court's decision. The result is that the marriage is considered to have never existed. A marriage can be annulled if it does not meet the legal requirements. The research method used is qualitative descriptive with an empirical normative approach. The purpose of this paper is to understand the factors that cause marriage annulment and the legal consequences of marriage annulment on the status of children. The results of this research are that the effect of marriage annulment on the status of the child resulting from the marriage is called "my status" meaning that the child is not decided by the father and not decided by the mother, but remains a legitimate child. In child care, if the child is under 12 years old, the mother will care for him, whereas if the child is over 12 years old, the child can decide to go with his father or mother. So the child's status is called "my status".
