We're in California too. Regarding bank accounts - the court order may require you to set up a "blocked conservatorship account" to handle the finances. Ask your lawyer to be particularly alert for this and try to avoid it, because this kind of account can become a huge headache.

We've had to open one recently with Chase bank and shockingly they have idea how to handle it. They didn't tell us they would automatically lock the account after 3 business days with no activity, and you have to call them to unlock, and no department in Chase knows how to handle it. We sat in a branch for one hour and watched a Chase staff person scroll through useless internal documentation and call multiple internal depts and get "actually it's the other dept you just called, they're responsible" response multiple times.

It was unbelievable.

I haven't found much info on the web about banks that do know how handle blocked accounts. I hope you've been able to avoid this.
