My ex and I have joint custody and he as given me written permission (no judge signed it) to take our little girl to another country to visit her grandma on vacation, even signed for the passport. Unfortunately, when he's displeased he tends to take back everything. How do I protect myself? Also, he is asking for a complete list of everything we are doing on our trip and all flight information. We've never asked it of each other during other vacations... Am I setting myself up for a disaster, when trip is already paid for.
