1. C.J.S. Partnership §§ 1–7, 17.]
“Copartner need not exist alongside partner. The joint relationship (i.e., that the existence of one partner implies the existence of one or more other partners) is clear to all native speakers of English…. Because copartner adds nothing to the language of the law, it should be avoided.” Bryan A. Garner, A Dictionary of Modern Legal Usage 223 (2d ed. 1995).
