Make a list of everything you own together & record it with your lawyer.
Mark what you would like on that list.
Have your lawyer send it to his lawyer & then take it from there.
Don't count on too much cooperation or a speedy closure.
Try not to predict what may happen, just liaise with your lawyer, let her do what needs doing & then wait for the response.
You will drive yourself crazy trying to work it out in your head, believe me I've been there done that.
For me I got to the point where we were on good terms, we had some agreed items in writing & we were to agree on the rest.
I should've known better because after that doc was signed I didn't get a single thing back.
