See if the court in your area has the financial forms online. If so, then fill them out yourself and bring them to the 30 min consult.
It sounds to me like your area will do a 50/50 split of assets - that's usually simple to confirm
So the remaining issues:
- alimony (esp if it's possible to get short term alimony for a couple of years until the full time opportunities open up).
- custody plan that requires STBXWH to be sober whenever he's with kids
I'd add:
- can the kids & I stay in our home and how to afford that (ie would child support be enough to make the mortgage?)
I'm in the US, so hard to know what the courts in your country, let alone your particular jurisdiction require. You could ask the consulting atty to send you those forms prior to your meeting - worst that happens is they say no.
ABSOLUTELY get copies of whatever financial records you can get your hands on. In my area, the court requires at least 3 months, as well as most recent annual statement for all retirement accounts, etc. (all of which is very clearly spelled out on their website. You may have to check things like "local rules" which should have a section on family law or domestic relations or divorce). Again, in my area that would include the mortgage/rent, utilities, banking, etc. I assume in Canada the principle is the same: how much do you make, have, and owe, and how best to "split the pie".
You may also want to look into costs for child care if you were to return to work full time.
And finally, even if the forms in your area don't ask, include EVERYTHING. Think of holiday gifts, vacations, etc. also things like haircuts, dry cleaning, etc.
Personally, I think it's easiest to just go over the bank statements for the last 3-12 months with a fine toothed comb. These days, you can usually download it to an excel spreadsheet and then add the categories the court uses (and your own for things the court misses). Doing that is another way to save attorney $$ (I can't tell you how many countless hours are spent basically creating spreadsheets from the paper copies that clients bring in). Another advantage is you can also do a spreadsheet for the assets (house, boat, cars, retirement, etc) and play with ways to make an "equal" distribution, as well as playing with how much monthly income is even available to split.
