A more thorough explanation:

Ne exeat is a legal term that means "that he not depart." It is a writ that restrains a person from leaving the jurisdiction of the court or the state. This writ is usually issued to ensure the satisfaction of a claim against the defendant. In family law, a ne exeat is an equitable writ that restrains a person from leaving or removing a child or property from the jurisdiction. This writ is often issued to prohibit a person from removing a child or property from the jurisdiction and sometimes from leaving the jurisdiction. For example, if a parent is planning to take their child out of the state or country without the other parent's permission, the other parent can request a ne exeat to prevent the child from leaving the jurisdiction. This writ ensures that the child remains in the jurisdiction until the court decides on custody and visitation arrangements. Overall, ne exeat is a legal tool used to prevent a person from leaving the jurisdiction of the court or the state. It is often used in family law cases to protect the interests of children and property.
