Just some thoughts I'm tossing out:
Filing tax returns
Child support and if you can it automatically deposited into your account versus having him provide you w/a check each month.
What about the current marital debt? Cars in both names or one in each name. Who is liable for car payments?
Be sure to ask about your portion of his retirement benefits.
Any 401K or any life insurance policies?
Health Insurance (stay on until you are divorce or see what your state offers)
What are you actually responsible for when the divorce goes through in the way of household stuff/expenses

You may not need the above suggestions, but they will help you to think of what you need to ask.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
