Duplicate

[Lat. duplicatum, from duplicare, to double.] That which is doubled, or twice made; an original instrument repeated. A document which is the same as another in all essential particulars.

Tindal, C. J., 1 Man. & Gr. 93. Maule, J., Id. 94.

Sometimes defined to be the copy of a thing; but, though generally a copy, a duplicate differs from a mere copy, in having all the validity of an original. Nor, it seems, need it be an exact copy. See supra. Defined also to be the counter part of an instrument; but in indentures there is a distinction between counter parts executed by the several parties respectively, each party affixing his or her seal to only one counterpart, and duplicate originals, each executed by all the parties.

7 Man. & Gr. 91, note. See 2 Id. 518, note.

And see Counterpart. The old indentures, charters or chirographs, seem to have had the character of duplicates.

See Duplicare.
