Your strength is admirable. I have read so many times that you know when you are done, and it truly sounds like you are getting there.
As a lawyer, I'm a little intrigued (and concerned for you) with the potential for a paralegal completing paperwork that is not reviewed by an attorney. I am licensed in 4 states and a national tribunal. In none of those states would this arrangement be allowed.
My suggestion, although not something that was solicited, would be to hire a financial mediator since it sounds like this is largely a property matter at this point (although your son is young enough that if you guys are not in agreement on custody issues--time, dates, third party introductions, holidays, etc. it would behoove you to discuss those issues with an attorney).
