The exact wording of the order is important. Sometimes a residence order is automatically awarded when there is a contact order. If a parent has a residence order in their favour they may take children abroad for up to one month without consent.
Whilst strictly speaking it is advisable to have consent to take children abroad on holiday when there is no residence order, the courts tend to take a dim view of those who try to prevent children enjoying the usual family holiday abroad. That is unless there is a history of not complying with court orders and holidays are used to frustrate contact or there is a flight risk.
There needs to be evidence of a flight risk to successfully apply for a Prohibited Steps Order, particularly if the country concerned is a signatory of the Hague Convention on Child Abduction. Applying unnecessarily for a PSO can be perceived as aggressive and controlling whereas applying for Specific Issue Order or attaching conditions to the order is often a more positive way of resolving arrangements for travel.
