Planning to Divorce - Tips?

I am planning to divorce my ADHD husband. It's been a long time coming. One of the reasons I did not do this sooner is that I fear that he won't do what he's supposed to do when it comes to gathering paperwork, responding to summons, getting his stuff out, etc. I don't want this to drag on and on and on. I also fear going completely broke but my parents are offering to help me which makes me feel a bit better.

Question - for those who have been through it or who are going through it, are you ADHD spouses keeping up with their end of the divorce proceedings? If not, what can be done?
