My heart goes out to your mate on this one, I am SIX years into a messy divorce and nearly 20 grand in solicitors fees. Sadly when you are married you dont have "yours and mine" just matrimonial assets and anything with a value of £500 or more has to be declared on Forn E (this is a very comprehensive financial declaration). I even had to supply information about money made from my sales box! ie record found at carboot sale for £1, sold at soul night for £10 and money made from hiring out my decks, once they get there claws into you they want blood. I eventually had to sell my collection (a decision I still regret) and bought a more suitable vehicle, this was deemed transfering an asset rather than disposing of an asset and is depreciating in value (as opposed to the records)
My one piece of advice would be if you friend thinks he is not being well represented to change his solicitor, I have changed mine and the new one is brilliant, the yellow pages are full of them and as you only get one shot at this think of yourself as fairness dosn't come into it.
I'm always reminded of the cartoon of two farmers pulling at either end of a cow and the solicitor sat underneath the cow milking it dry!!
Good Luck
