As far as the passports, you're right about the kids passports. They are good for 5 years, but the kids names aren't going to change due to the divorce. The reason I was focused on hers was that why would she go through the money and effort to have to turn around in a couple months and change the name. I know that she can change it and it isn't difficult to do, but there is no trip in the immediate future, so to not wait doesn't make any sense. Her thing is that she loves to travel, though we haven't been able to for financial reasons. However, even post divorce, our financial situation will be worse, so I doubt she'll be able to do much traveling, especially during the next couple of months.
Long story short, to get you up to speed, my wife filed for divorce, but is not going to serve me for 90 days, of which I have 60 days left. She has been extremely depressed for years now and has only recently gotten any help for it. Her attitude and demeanor has changed drastically over the past couple weeks and I've been doing 180s up the wazzu. Things seem to be improving, but she has not stopped the serving date and has not told me that she wants to stay together. THat's the reader's digest version, there's a lot more to it, but that will give you a general idea.
