Abstract. We present some results concerning Poincar\'e-Dulac normal forms of
dynamical systems which are symmetric under (possibly nonlinear) Lie point
transformations. We show in particular that the vector fields defining the
dynamical system and the Lie symmetry can be put into a "joint normal
form".
