Answer
Based on official Jordanian legal texts
The decision on a child's travel under Jordanian law is tied to the guardian's guardianship. Article 177 of the Personal Status Law provides that whoever wishes to travel with the child outside the Kingdom for a lawful purpose obtains the guardian's consent; if he does not consent, the court may permit the travel after verifying that the child's interest is secured and stating the duration of the visit, while taking the necessary guarantee to ensure his return.
Article 176 also addresses the residence and movement of a child holding Jordanian nationality, making it subject to the guardian's consent or the court's permission. This connects to guardianship over the person under Article 184, where the guardian is the decision-maker in pivotal matters such as travel, its destination, and duration.
The custodian — even if she is the mother — therefore cannot independently decide travel with the child outside the Kingdom without the guardian's consent or the court's permission, to protect the child's interest and the other party's right.
Assessing permission to travel and its conditions remains within the Sharia Court's competence on the facts of each case.
This is a general explanation based on Jordanian Personal Status Law and does not replace advice from a qualified lawyer in a specific dispute.
