free half hour ... Some solicitors offer it, some don't, and it may not be much use even if they do
Not true. It is astonishing what they pack into half an hour. It is extremely useful time in which they assess the situation, crack through a general outline of what to expect eg settlement, children; how representation will be paid for. Ime I paid for representation over years at £40pm but in your situation you could price domestic abuse eg financial abuse.
Plenty of us have successfully divorced men like this - I am one. I remember thinking he was too clever, too cunning, too vicious etc etc. Yes he was all those but he was not above the law. The law won - hands down, actually.
You MUST, in the first instance, contact women's aid 0808 2000 247. Lines are busy during the day but you can leave a message and they well get back to you - leave details of a safe number and safe time to call. Or call at night (7pm-7am). Or email - you could link this thread. Be ultra careful with any online activity - Women's Aid website gives detailed instructions how to do this. From now on you need to act with stealth, he musnt know what you're doing or he will lock everything down. Is he self-employed?
You can do this - with Women's Aid at your side. Step at a time, many have walked this way. If I can do it against Satan himself, anyone can.
