  We study the anomalous magnetic and electric dipole moments of charged
leptons in supersymmetric low-scale seesaw models with right-handed neutrino
superfields. We consider a minimally extended framework of minimal
supergravity, by assuming that CP violation originates from complex soft
SUSY-breaking bilinear and trilinear couplings associated with the right-handed
sneutrino sector. We present numerical estimates of the muon anomalous magnetic
moment and the electron electric dipole moment (EDM), as functions of key model
parameters, such as the Majorana mass scale mN and tan(\beta). In particular,
we find that the contributions of the singlet heavy neutrinos and sneutrinos to
the electron EDM are naturally small in this model, of order 10^{-27} -
10^{-28} e cm, and can be probed in the present and future experiments.
