Duplicate original means an exact copy of a signed original, an exact copy with signatures created by the same impression as the original, or an exact copy bearing an original signature.
“Duplicate original” is a legal term that applies to two or more copies made simultaneously, each of which can stand as the original document.
When two written documents are substantially alike, so that each might be a copy or transcript from the other, while both stand on the same footing as original instruments, they are called “duplicates.” Agreements, deeds, and other documents are frequently executed in duplicate, in order that each party may have an original in his possession.
We are already familiar with this concept from our everyday lives. Speakers at genealogy conferences sign two copies of their speaker contracts, one for themselves and one for the conference program chair. When we get divorced, both we and our spouses receive copies of the separation agreements and the divorce decree.
