Should apply, "Community Property". You get 50/50 even retirement. Dont be foolish and walk out. Make him move, like the poster said, would be considered abandonment. Ive been to court half a dozen times Pro se, because im broke from attorney fees. Not that difficult.
Main thing is to find someone's name you know who got divorced, get a copy of the decree and use that as a reference syllabus and start typing. File. Call around, you might be surprised to find that some attorney will work with you on payment esp if they know you're going to get a settlement. You'll get the jist of it. Dont ask the Circuit Clerk for anything but paperwork thats all they'll offer. Document, document and document everything! Cant stress that enough.
