As a practising solicitor, I would like to make a few comments:
1. Almost nobody who goes to court in a family law situation comes out richer. Usually,everybody loses. Everybody knows this, but the reality of adjusting to a poorer lifestyle still often comes as a shock. In these circumstances, it is very hard for a family law solicitor to have a well-satisfied client.
2. If family law were an attractive\lucrative option, more solicitors would do it and price competition would have some effect. In reality, many solicitors flat out refuse to do this work. Those lawyers who are prepared to undertake this extremely stressful work undoubtedly charge accordingly.
3. Undoubtedly, there are some cases of very high charges in the family law area, accompanied by some lack of transparency to the customer as to how these charges are calculated. Usually, the Law Society will be very helpful. I rather suspect that if somebody has found the Law Society "totally unhelpful" then it is likely the case that the legal fees (though obviously a shock to the client) are not out of order. In any event, there are other avenues, such as taxation (which is independent of the Law Society).
4. It is often the case that costs which you are awarded in court will not fully cover your legal bill. This is particularly often the case in family law matters, and there are good reasons for this.
