👉 In family law, a "coparent" is a parent who has legal custody of an infant child but does not have primary physical custody. This means that the other parent has full control over the child's life and upbringing, but they retain some level of parental authority or responsibility in certain areas such as making decisions regarding medical treatment, education, and parenting schedules. Coparents are often appointed by a court to ensure the best interests of the child.
