This article examines whether paternity leave influences father involvement among nonresident fathers, if associations differ by coresidential status, and whether leave is a stronger predictor of nonresident father involvement than other indicators of father identity or interest. Fathering promotes child development, yet many children are born to unmarried parents and do not live with their fathers. Paternity leave may increase fathering among nonresident fathers, but extant research has largely overlooked these fathers.
