A more thorough explanation:

Annulment of adoption is the legal process of canceling or revoking an adoption. It is also known as abrogation of adoption. This means that the adopted child is no longer considered legally adopted and the adoptive parents no longer have any legal rights or responsibilities towards the child.

For example, if a couple adopts a child but later discovers that the birth parents did not give their consent or that there was some other legal issue with the adoption, they may seek an annulment of adoption. Another example is if the adoptive parents are found to have abused or neglected the child, the court may order an annulment of adoption to protect the child's welfare.

The annulment of adoption process varies depending on the laws of the state or country where the adoption took place. It typically involves filing a petition with the court and providing evidence to support the request for annulment. The court will then review the case and make a decision based on the best interests of the child.
