Get a solicitor now! I split with my ex 7yrs ago, as he was an abusive bully, I didn't get legal help then as I was too scared of him. I wish I had found the courage. He has started bullying our children, and as I am now with a wonderful, caring partner who works, I am not eligible for legal aid, and if this goes to court (access and stuff) I will be forced to pay. We are only �20 a month over the limit but have been told to expect fees upwards of �5k (which we don't have). I have had the maintenance sorted recently through the CSA and am awaiting the first payment, but it would have been easier, and I would have been better off if I'd sorted this before. Don't risk your's and your kids emotional wellbeing, sort it now, and make him pay what's right. Good luck .
