Secondary Evidence Law and Legal Definition

Secondary evidence is evidence that has been reproduced from an original document. For example, a photocopy of a document or photograph would be considered secondary evidence.

Such evidence is admissible out of necessity, because of the impossibility of producing the primary evidence. For instance, when an instrument pertinent to a case has been lost or destroyed without fault on the part of the party, a true copy or oral evidence of the contents is admissible.
