The sidebar says

Prepare. Quietly. Assemble copies of every account, every lien, every tax return, every asset you can. Take dated pictures of your home and its contents. If you can liquidate any accounts - yours, hers or jointly owned - do it now. If you can sell any assets for cash, do it now. This is the same advice given to women, and for good reasons.

What's the point of liquidating accounts? In my state, all accounts will be divided 50/50, whether individually or jointly owned. Does this mean convert them to cash and then not report the cash at financial disclosure time? That sounds both illegal and your ex / court will know that you have the money anyway. Or you'll have to explain how you spent it. No?
