Obviously there are good points from lots of people on here including the solicitors and lots of different issues.
Some barrister will not have conference without a solicitor present nor do court hearings. In my business law I sometimes try to ensure I am not present at a hearing although it depends on the case and what the client and barrister want. I put people off going to court every week as it is expensive, usually costs double what anyone incl,uding the lawyers necessarily expect and even with a sure fire winner case a witness may do badly on the day or the judge takes a different view so it is a massive lottery exercise at times and always has been very unpredictable in many areas of law; therefore accpeting much less monety than you might get at a hearing can sometimes be better but it's not a precise science.
We negotiated via our solicitors (I paid both solicitors) on our divorce and directlly, reached various verbal agreements and then we got to a point where my husband wanted even more and then I okay that's tipipng point we will have a hearing then and that was when he agreed on our final amount - he got 59% of joint aseets and no obligation to support the children and I got a clean break - did not have to pay him maintenance. Niow that 59% he got is fairly high although lower earners even those working full time like he did sometimes do get 60% + sometimes more. Had we gone to court it was possible he would have got even as low as 39% of joint net assets. So I sitting there with my mental calculator and also thinking of the psychological effects of having ig hanging over me another year and just bit the bullet and agreed his 59%. (He got my life savings, all my shares and a very large chunk of the house equity and I got an obligation to pay 5 sets of school fees, childcare, university costs for children and to house the children (he never has them) and a £1.3m debt.
On a few of the many points raised above if documents prove someone has charged for something that did not happen that is not usual or reasonable. I would never do it. In fact I have often had conversations with clients and barristers about if they want me to the call or not - if I am on the call I charge for it, if not I don't. When my father died his lawyers said they had incurred 70 hours of time on something over 2 years. It was a ridiculous. We paid but it illustrated to me why I invoice every single jmonth, whty i explain on the invoice what work i did in that month and why I try to ensure in most matters clients know in advance what a particular task will cost particularly if they are not used to using solicitors.
From this month there is a new obligation for those solicitors (not me) who do consumer law work of certain kinds to try to give a reasonable estimate of the range of fees particular work may cost but it is very hard to predict with litigation.
I would suggest people print their own files by the way which I do in personal things - each substantive email and document print it out and put in date order as it comes in no matter who much trouble that seems to feel at the time as it gives you an awful lot of power and easy reference to documents and then if you need to copy it you can just send it to the local copyshop to copy the whole thing.
On the litigation loans I just don't have experience of them.
