Courts CAN make time for this if someone files a motion for a discovery, etc. That's not likely to happen unless someone is either vindictive (very possible) or if they have suspicions. Judges, generally speaking, will not just rubber stamp every motion for a subpoena; there has to be something reasonable for the request.
In either case, if you **compromise** and come to a settlement, none of this will necessary. And do keep in mind some very good advice I was given by a friend when I went through domestic court: You will never be sati fished with all the details of your divorce. If you accept that from the beginning, then you're more likely to settle, and that will keep everything you want kept secret just that way.
True, there are plenty of domestic attorneys who love to keep things going because it lines their pockets, and your wife may very well have one of these. You need to research your choices of attorney so that you don't wind up with one of these. When you go for a consult, feel out the attorney. If they themselves bring up settling, even hypothetically, then you know you've got an attorney (or maybe) who is not hell bent on dragging out the whole thing. And any good attorney is going to tell you the same thing: You willn never be happy with every single detail of your divorce: prepare to come to a peaceful settlement, leaving apparenaces in court out as well as motions for the judge to get involved.
Ive got similar concerns about my situation, so this stuff is always on my mind. I agree that cleaning up your computer is a good place to start, especially if you are still haring the home. Remember, anyone can install a keyboard stroker, and if that happens, all of your secrets are out.
As for the cash advances you'v gotten off your credit cards: if it ever comes to that, perhaps you can 'admit" a problem with gambling, that you then joined Gamblers Anon, and you are .. .viola! . . . healed! (Or recovering, as they say in those groups.)
I feel for you. Like I said, I've got similar concerns alls the time. Makes sense to try to settle as well as being very, very carful about what you do and the paper trails you might leave.
