Hi I have 3 children ages 18 14 and 9. I am still legally married to my "ex" husband and we all have the same surname. We have been separated for nearly two years. As far as I can understand it he does not automatically have parental responsibilty for the older children as we were unmarried when they were born and it was before 2003. He does not see the children at all and only pays less then half the maintenance he should and if he hears from the maintenance place I get letters from the mediation firm threatening him taking me to court for access until I agree to accept the less amount. The relationship and marriage was emotionally and physically abusive. There has been no court action/order and he hasnt seen them since 2014. I am hoping to save enough to take them on holiday abroad this year but my main worry is would I need his permission to do so?. He certainly would not give it and not without some stipulation involved. How do I stand with this and will we have to wait until my youngest is 16 to go abroad? Thanks for any help on this matter.
