My Ex and I have joint custody of our two children (11 & 13). I had notified my ex 3 weeks ago about taking the children to the USA for the weekend driving across the border. She said she had no problem with doing so. (We have agreed at a PN7 intervention that the ex would keep the passports and hand them over two weeks prior to travel). I have requested the children's passports and times she is available to get a travel consent letter signed and notarized for the last two weeks. She now has refused to provide any times she is available for me to get the letter signed or pick up the passports. I have emailed her lawyer about the situation and she has forwarded my concerns but still no response. We had planned to leave this Friday but time is running out. Is there anything I can do that I haven’t done already? Or am I SOL? Thanks…
