We determine all the totally umbilical lightlike Monge hypersurfaces of $R^4_1$. This is done by using the Bejancu-Duggal method [1] of studying lightlike hypersurfaces and then integrating a system of partial differential equations.
Classification : 53C40 53C55
Keywords: lightlike degenerate hypersurfaces, totally umbilical, screen distribution, lightlike transversal vector bundle
