Depends on where you live if all that matters.
What you could probable definitely use is any receipts where he spent money on her, which you could possibly get half of back..
I would suggest keeping all those records for you emotionally to remind you what happened and keep your resolve.
For the appointment, you want financial statements. If you haven't already, find EVERY important document you can find, make copies, and bring them to your lawyer. It's not about emotions anymore. It's a financial war...
ETA: There's probably plenty of websites telling you what documents you're gonna need for divorce, but just some examples: Birth Certificates, Marriage license, car titles, other asset titles, retirement statements, ALL credit card statements, savings/checking bank statements, any loans, car loans, mortgages, debts, assets, appraisals, paycheck stubs and W2s, etc.. Definitely find all this and make copies. I just made a couple jump drives for most of it and hid them in different places..
And it's not really that hard. Most companies now you can just go onto the website and download and save all the statements without every having to print. That's probably how the lawyer will want them anyway.. Paper copies cost money..
Dont get overwhelmed. How do you eat an elephant? One bite at a time.
Oh, and I couldn't get my ex's true info until I subpoenaed the information through his employer. He refused having a pension plan until we went through his job and found out he was lying. Check his credit score too before you file and see what you find...
