she needs to take her and the kid's documents, the cash and go to her local homelessness unit. she can tell them that she is subject to domestic violence and they will immediately rehouse them (although this may be in a refuge to begin with.....but eventually she will get a council house - it depends on where she lives/ends up and the length of the housing list). the council have a duty to both her and the children IMMEDATELY to remove them and house them somewhere where he cannot find them. i then suggest that she reports the husband to social services regarding the controlling behaviour (as it is a form of abuse - emotional abuse - if directed at a child in any way, or they are witnessing the behaviour under the update of the children's act 2013. local safeguarding policy will state that they then support her and her children during the transition period and they may investigate the 12 year old stepson again as well). just because he has all the money and the perceived power does not mean she cannot leave the situation if she wants to do so. it may not be easy, pretty or what she ideally wants, but it is a legitimate and semi-solvent way out of the abusive relationship. but she should try and plan carefully to take documents, cash and as much as she can carry with her as it will be like wiping the slate clean. she will need birth certificates etc to claim benefits and prove the kids are hers. i have been in that situation and walked out of my first marriage without warning (it took careful but very quick planning)with £200, documents and one change of clothes. i effectively disappeared from his life and it was the best thing i ever did. sure - it takes a while to get back on your feet and can seem an impossible task (as controlling behaviour is very clever). but from your description, if she wants out, she should do it quickly, cleanly and at the first chance she gets. no homelessness unit can turn a woman away who claims domestic violence - they have to house them on that day they go to the unit. they then have too investigate everything after the woman is safe, not before, and if they say anything different they are lying. the charity women's aid can also advise her, but it is best to contact them when at work or from a phone box so he does not get a whiff of what's coming. it really is up to your friend, but this advice and opportunity out may be the push that gives her the courage to leave. sod solicitors, sod everything else - get her out of there FIRST and then everything else can be sorted after. she can also use the husband's denial of the problem as a risk factor to her two children.
