Ask HN: What legal notices do I need on my website?
Is this even something I can find out, or is it something I have to have a lawyer for?
I handle quite a bit of PPC of clients using google adwords. There has been quite a bit of buzz about what policies to include to be compliant and I just extrapolated that if it's a requirement for Google when it comes to advertising it's not a bad thing to have on your site for other purposes.

I always configure a:
Privacy Policy Terms of Service Copyright symbol Designated agent and DMCA
The only other thing you may want would be a terms of service and that's fairly rare to see.
