A multilateral access system for a multilateral well including a main well bore and at least one lateral well bore includes a tubular workstring having an inner string and an outer string. The outer string includes a diverter body having a cylindrical housing with a lateral window, the diverter body being shaped and dimensioned to direct the inner string the lateral window and into the at least one lateral well bore. The system is used by positioning the tubular workstring within a multilateral bore. The method further includes positioning the diverter body such that the window of the diverter body faces a milled casing window of the lateral well bore and moving the inner string upwardly above the diverter body. Subsequently, the inner string is lowered back though the diverter body, wherein the diverter body exerts a lateral force on a lower end of the inner string urging the lower end of the inner string toward the milled casing window.
