zipzap that is true, however, there are some benefits to him having a decent lawyer, in that it can help keep your OWN costs down. The crap ones are disorganised, run up unnecessary costs by being late, not responding, sending useless, provocative, inflaming letters etc. Better ones sign up to Resolution. So although it's a cynical thing to do, and perfectly legal, it can actually make things worse for yourself.
And secondly, many of the best solicitors pick and choose their cases so they don't necessarily give free half hours.
Wise best you put yourself in the driving seat and take on the early costs (the initial court fees) so that means you can control when things happen.
He can divorce you because your left nostril is bigger than your right nostril - grounds are practically irrelevant nowadays except in very, very, very extreme situations. So it's best you get your petition filled in and sent to him for approval on the grounds before you send it to court (reduces animosity).
However, an alternative is to not divorce on the grounds of Unreasonable Behaviour, but two years' separation as it's less acrimonious. Clearly you have to do the two years though - so this will depend on whether this is in your interests or not. If they are being financially difficult then get cracking with a UB divorce. The sooner you file, the sooner the finances can be sorted out. A good solicitor will explain all this to you.
Remember there's TWO parts to divorce. Firstly, the divorce. This is an application to the court to dissolve the marriage. Can be done at any time but you don't actually need to go to court in person to do this. It's a bureaucratic thing.
And secondly, what was called 'Anciliary Relief' - that's the money, and that's a completely different legal process than the former. If you can't agree to divide up your assets, and make provision for both your needs, then you'll want to start mediation first (unless you can get out of it, which most can't). It's compulsory for couples who are turning to the courts for assistance (many, many couples do the finances without court involvement).
A good book is 'Family Law Made Simple' by Gordon and Slater - but it is not substitute for actually seeing a lawyer. Also David Terry's divorce forum (google it) is handy too (and free!) Good luck - it's a horrible thing to have to do, but you will survive it.
