Abstract. We provide a unified treatment -- including some new results and
improvement of old ones -- of normal form theory of dynamical systems
(or vector fields) for what regards its symmetry properties under
nonlinear transformations (Lie point-symmetries).
We also briefly discuss the problem of the convergence of the
normalizing transformations in the presence of symmetries.
