No.
Short but sweet eh?
Seek legal advice as soon as you possibly can Kimlou.
There would only be refusal if you had abused your children and they were at risk of it happening again. She would need to prove this with both Social services and police reports.
good luck
P.S....can i just add something from my own point of view - PLEASE make sure that your children are not suffering because you and your ex are arguing. From my point of view, if children DO NOT want to see their parents, then the parents should take this into account and should not force the issue.
sorry guys - just from experience i feel strongly about this and YES i do know that the law says children should have a relationship with both parents, but thats something that can be argued all day
Good luck Kimlou xxx
