(a) it is clear, on its face, that it is an act of the person who is an act or, as the case may be, of the parties (whether by qualifying as an instrument or by presenting themselves as an act, by signing or signing or by signing or otherwise); and why do my leases (and many others) provide for the signature as a document? (This also requires that the signatures be attested and that the document, to specify it, be signed in the form of an act). In most cases, this is implied anyway, but if it is signed as an act, there can be no argument. Having to sign the document as an act adds that extra touch of solemnity that I hope will help people realize that this is a serious matter. . . .
