Oh, dear, hope you're ok (ish_.
First things first, google "legal services commission eligibility calculator". That will take you to the legal aid website & you can see whether you'll get it. Don't put your dh down as partner, just your salary, savings etc. When it comes to equity in your house, put down half after taking £100k off. Eg, if you jointly have £220,000 equity, you presume you have £110k, knock off £100k, and insert £10k in the box (actually, if you have more than I think £8k, you won't qualify).
If the calculator works out that you are eligible for legal help, then go to Resolution.org.uk to find a local family specialist. When making the appointment, first say that you believe you are eligible for legal aid, as a lot of firms (mine included) don't do legal aid so it would be a waste of time seeing them.
At the first appointment, take along a basic list of assets (house, savings, endowments, pensions) and liabilities (rough figure for outstanding mortgage, loans, credit cards etc).
Most firms offer the first half hour free if you're not eligible for legal aid.
If you have children and earn less than your dh the usual presumption is that you would receive the majority of the capital plus a share of his pension (depending on length of marriage) plus poss. spousal maintenance.
He'll have to pay child maintenance at 15% for 1 child, 20% for 2 and 25% for 3 or more.
Hope this helps.
I'm just about to go on hols for a fortnight so sorry can't help further, but good luck!
