Gov. Chris Christie has signed legislation, spurred by a federal civil rights lawsuit, that will require insurance carriers contracting with the state to cover fertility treatments to women in same-sex relationships, and those in other nontraditional relationships.

Christie signed the bill, A-1447, on May 1, without comment. The new law goes into effect in three months.

The bill—sponsored by Assemblywomen Pamela Lampitt, D-Camden, Valerie Vainieri Huttle, D-Bergen, and Assemblyman John McKeon, D-Essex—was introduced in part in response to a federal lawsuit filed last year against the state by a same-sex couple whose application for fertility coverage was denied by their carrier, Horizon Blue Cross Blue Shield of New Jersey.
