Family law/court advice please

[wjwren]

Afternoon, my girlfriend has children with her ex husband, he see's the kids sometimes once a week but will make a point of only having one of the children at a time to be awkward so she cant go out or do things herself. He is very abusive and we have called the police on a couple of occasions. Is there some kind of access order to enable him set access times and some kind of structure - does this have to be done via the courts or can we apply ourselves? Legal aid still available?

thanks
