Congrats on your first post and welcome to the forum! As far as a resource that lists that information by state, other than doing a simple Google search I'm not sure where to guide you. I do know that states are different - we had to do some agreements in WI a few years ago and there was a 7 day revocation period for anyone over 40 (or was it 21? I can't remember!). The easiest course of action may be to ask an attorney with access to Westlaw or a similar website.
