6+ months of LC, meeting stbxw to sign papers at her request. What to expect?

[Man-guy]

Title sums it up, I wasn't able to file a while back like I'd wanted, but I just moved on with my life and figured eventually this would creep it's way up. Well, it's here next week, any expectations/tips? Not personally looking to reconcile or anything, I just want to know if I need to prep myself to jump out of the way of a Corolla I also realize that this is for the signing of the papers and probably catching up, nothing more. Extremely limited contact since the surprise separation, haven't spoken on the phone or seen each other except 2 weeks after she left to try and reconcile, just rare messages back and forth for mail or items since. Any advice is appreciated, I'll fill you all in once this goes down.
