Yes. Best practice does say that there should be a legal disclaimer, highlighting the confidentiality of the proposal’s content and how the information may or may not be distributed, used, copied, etc.However, if this is over done, it can leave the person reviewing your document feeling as if they’ve been put in hand cuffs.
Witness the following disclaimer from an e-mail received by one of our associates.
Only the company name and information has been changed. As the saying goes, you can’t make this stuff up folks. If you’ve seen one that’s even longer, send it along (with a generic name inserted, of course.)
