Abstract: A technique facilitates creation of and production from a multilateral well. A lateral junction is deployed downhole to a lateral bore via a conveyance, such as a coiled tubing conveyance. The lateral junction comprises a main bore tubular and a lateral bore tubular which are pivotably joined via a pivotable coupling. The pivotable coupling enables pivoting of the lateral bore tubular outwardly through a lateral opening of the main bore tubular.
