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".
