Answer
Based on official Jordanian legal texts
Yes, travel with a child can be prevented under Jordanian law, because traveling with him outside the Kingdom is contingent on the guardian's consent or the court's permission. Article 177 of the Personal Status Law provides that travel with the child outside the Kingdom is only by the guardian's consent, and if he does not consent, by the court's permission after verifying the child's interest and taking the necessary guarantee.
Article 176 also makes the residence and movement of a Jordanian child subject to the guardian's consent or the court's permission. This means one party cannot travel with the child outside the Kingdom without obtaining this permission; absent the permission, the travel is not allowed, and the party with the right may ask the court for what preserves his right and the child's interest.
Preventing travel with the child without permission therefore rests on a legal basis — the requirement of the guardian's or court's consent — to protect the child's interest from travel that may harm him.
Assessing whether to permit or prevent travel 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.
