I'm being a little hypocritical here, but once my business was able to pay me a paycheck, I carved out about 20% per pay period via direct deposit and put it into a new account that was solely in my name, where W couldn't access it. I did this because she kept casually playing the D card, and I wanted to protect myself just in case. And if things work out we'll have some extra money for the kids college fund or something.
But, my IC did caution me to talk with a lawyer about this, which I have not done.
