Advice on court re holidays.

Hi, I have a court order, from last October, with ex for contact with our 3 year old boy.
It states that I have 3 weeks of the main school summer holidays and all other holidays shared equally.
Now, my ex refuses to tell me which holidays she has booked off from work for the year so I don't know which ones I can have to start making arrangements.
If I have to take her back to court to sort this out is it an Enforcement, Specific or a Vary/Amend Order and do I have to go through mediation again even though I know she won't go?
Cheers, Andy

I would write to her, send it recorded delivery with a suggestion of how the holidays could be shared. She will hopefully write back with a different option to suit her but at least you should know when you will see him. I have to do this every year with my partners ex. I send her a new calendar each August for the new school year, I'm sure she hates it but we only 'suggest' the dates to her so she feels she is still in control. It's all a game to her!If you don't get a response in say a week, Write again asking if the holiday dates you suggested were ok? If you still get nothing Write to her reminding her of the court order and you will have to take the matter further if she fails to respond by a given date. Our court order says the holidays are to be shared and agreed between the parties I'm presuming yours is similar? If she is refusing to engage or agree then you will have to go back to court. I would think it would be a c79 enforcement as she is not complying with the order. Hopefully it won't go to that.
I don't think they make you go back through mediation but if they do and she refuses that looks even better for you as you will be the reasonable one and she being the uncooperative one.
