I have been separated nearly two years and he won't sign divorce papers. We are both in new relationships and I have booked a weeks holiday with my new partner and kids in June. He use to get them two nights a week until I found out he left my 7 year old sleeping on house with her 12 year old sister to apparently drop keys at his gf on a pub. So I stopped contact and said he could have them one day a week until trust was gained via lawyers. Now he saying I have committed fraud as he hasn't signed passports which I know is rubbish as all his details were on form and only one signature was required and he is saying he is going to stop me taking them. Can someone help me can he do this? This is my children's first forge in holiday which I have worked hard to be able to afford and don't want him ruining it
