Purport defines an instrument's substance as it appears on its face, distinct from literal tenor or delivery. Purport denotes the substance or substantive meaning of a written instrument as it appears on its face, contrasted with tenor, which denotes an exact copy or literal form. 'Purported' suggests deficiency or that matters may not be as represented, and an instrument that only appears to convey rights will not be treated as purporting to convey where requisite acts like delivery are absent. The concept applies to entire instruments and to parts of instruments to the extent the face of the document shows that resemblance or intention.
