I suspect that the lawyers are nervous about giving advice when they don't
have the financial information to see just what is at stake.
I'm
no legal expert but what I'm happy to share my understanding:
Keep in mind that divorce and financial settlements are different things.
To properly agree a settlement you will need a
consent order (I think that's something that can be
done via Wiki) but a judge will only rubberstamp it if confident that you
both thoroughly understand and agree the split and that you have been
properly advised.
I envy you if you can sort it all out
amicably - what you think as being fair about maintenance etc. might be
different to what your husband sees as fair. As my solicitor said "you'll
only get one bite of the cherry, and you can't come back for more later". I
would advise you not to agree to anything in a hurry without doing a lot of
research first.
