The Quintipartite Deed was a legal document that split the Province of New Jersey, dividing it into the Province of West Jersey and the Province of East Jersey from 1674 until 1702.
On July 1, 1676, William Penn, Gawen Lawrie (who served from 1683 to 1686 as Deputy to Governor Robert Barclay), Nicholas Lucas, and Edward Byllynge executed a deed with Sir George Carteret known as the Quintipartite Deed, in which the territory was divided into two parts, East Jersey being taken by Carteret and West Jersey by Byllynge and his trustees. The Deed divided New Jersey by a straight line from "the Northernmost Branch of said Bay or River of De la Ware which is in forty-one Degrees and forty minutes of latitude…unto the most southwardly poynt of the East syde of Little Egge Harbour."
