We prove that if an almost parahermitian structure of the ambient space induces the identity endomorphism of the radical distribution on a paracomplex lightlike submanifold, then there exists the global lightlike transversal bundle, which is uniquely determined with respect to a screen distribution and a screen transversal bundle of the lightlike submanifold. As an application, we give a sufficient condition that paracomplex lightlike submanifolds in a parakähler manifold are minimal.
