What is the ruling on child custody in a case where the mother holds dual nationality, has renounced one of them, travels frequently, and resides permanently abroad, while the husband also resides abroad, and the children reside in Egypt?

If the children are under seven years old, the mother has a greater right to their custody, unless there is an impediment. If they reach the age of seven, the predominant view is to consider the child's best interest in custody. The travel of the custodial mother is of two types: if it is a travel for relocation, custody transfers to the father. However, if it is a temporary travel for a visit or an outing, her right to custody is not forfeited as long as the travel is safe.
