"Further, the Affiant sayeth not" what is – that?

It shows up on affidavits, and as a rough translation means, I suppose, "also, I (the Affiant) are not saying nothing", but it seems a figure of speech, as if there is something magical Amulet that protects the signatories of something, but I'm not sure what that is shown. Can someone whose been through the law school to clarify this for me?

An affidavit is a sworn statement. The boundaries of the affidavit is within the document. Since it sworn, each intentionally incorrect information could result in perjury. "Further Affiant sayeth not" is archaic and one sentence that I do not use, but it is widespread. It means – "These facts are the limitation to the facts, I will swear." It protects the signatories of a perjury.
