I need #FediHelp. How do I find a decent financial advisor? Are they all the same? Does a financial advisor know tax answers or do I also need a tax advisor? Are they legally bound in some way to not scam us?

My mother left our adult kids really (to us) complicated money. I don't know what I'm doing and neither do they. We don't want to screw this up. Any advice on where to find legit help is welcome.
