Zusammenfassung:	A method and apparatus for completing a wellbore junction, wherein, in one embodiment, a first leg of a screen is fastened within a first tubular with a preformed window. The first tubular houses a whipstock with a cut-out portion containing a folded second leg of the screen. The first tubular is lowered into a junction of a central and a lateral wellbore. A second tubular is lowered within the first tubular and catches an end of the folded second leg of the screen thereby unfolding and expanding the screen as the second tubular is guided into the lateral wellbore.
