Sometimes vendors sell forms the same way other companies sell deodorant: "Buy this or you will stink."
While it's possible that some states have privacy laws that require disclosures, there aren't a lot of them; i.e. the vendor is intentionally creating the idea that your state might require something when it probably does not. I encourage you to post your question in your state forum or just call the vendor, tell them you are thinking about buying their forms and ask for a citation to the applicable law or regulation for your state.
I don't mean to misrepresent the situation by saying that forms vendors may occasionally mislead bankers. Sometimes, they just lie.
