In a recent publication, we suggested a mechanism for obtaining dynamical CP violation in the early Universe based on the out-of-equilibrium evolution of complex scalar fields. In this paper, we suggest several ways of transferring the CP asymmetry from the scalar sector to the leptonic sector. In particular, we point out how a ``transient MNS(P) matrix'' can generate an asymmetry between fermions and anti-fermions directly.
