Please make an appt. today to see a lawyer next week. Your H said he would mail the papers to you if he wasn't in the area in the next few days. If he doesn't show up, and you don't get them in the mail, contact him on Monday and tell him you made an appt with a L and you need the papers faxed right away. (Get your L's fax number when you make the appt.) If you don't get any papers by the time of your appt, then have the lawyer start to draft your own.
Assuming he is in the area, do you expect he will try to just drop by? If he comes to the door to "drop off" the papers, thank him and tell him you will review them with your lawyer, and then shut the door. Don't read the papers then. If he engages you in conversation, step outside and close the door.
To enforce this point, you can even take the papers, drop them inside, close and lock the door, go to your car, and proceed to run an errand. "Thanks for dropping them off; I'll look at them later, but I'll have to have my lawyer look at them before I can sign anyway. Would you mind moving your car? I'm on my way out."
