"Family, friends, GP, womensaid, some legal professionals are all go to court - get the abuse looked at, it prob won't make a diff but you have done best for your child and there will be something in writing to stop ex bullying and threatening. Other legals are saying stay out of court, and most recent views here suggest doing same."
The legal professionals who have advised you to go to court - are they experienced in dealing with cases where there has been domestic abuse and violence? And the legal professionals who advise against court - what about their experience of this area?
I wouldn't be surprised if the more experienced ones are advising you to go to court, because they realise that you're unlikely to get a fair arrangement without it. As you said yourself, mediation is unlikely to work with an abusive man, who by definition is going to be unreasonable and make ultimatums and threats.
You might feel you've heard enough advice and opinions already, and anything else would just complicate matters further, but if you do want any more advice you could call the free Rights of Women family law helpline.
FWIW, my two cents is that if your friends, family, GP, Women's Aid and some legal professionals are all advising you to go to court, they can't all be wrong. If your previous/current solicitor is advising against it, perhaps you could change solicitor? Or at least consider other options?
