Superconductivity in materials without spatial inversion symmetry is studied. We show that in
contrast to common belief, spin-triplet pairing is not entirely excluded in such systems.
Moreover, paramagnetic limiting is analyzed for both spin-singlet and-triplet pairing. The
lack of inversion symmetry reduces the effect of the paramagnetic limiting for spin-singlet
pairing. These results are applied to MnSi and C e P t 3 S i.
