Krysta, there is no way that she can go back to court to change the agreements if your boyfriend has not done anything wrong. The courts have ruled the way that they have for a reason. Your boyfriend needs to give permission for his ex to take his daughter anywhere and that means that she definitely cannot take her to Germany. It sounds like his ex is still going to try and make this messy, so be ready for what is to come. However, your boyfriend must stand his ground and be prepared. I would suggest getting in contact with a lawyer soon to make sure he will be handling the situation to come in the right way.
