Thank you for your question
My name is ***** ***** I shall do my best to help you
Whilst technically she needs the agreement of her ex to take the child abroad she does not need him to sign the Passport Applictaion form - she can do this alone
Please ask if you need further details
If she is just going on holiday she should give him the details in writing - including flight details and where she is staying - well in advance.
Only if her ex actually successfully applies to the court for an order preventing the trip is there a problem if she goes - and the court will not grant an order to prevent an ordinary holiday
Are you aware that the site charges more for a phone call?
