Abstract
A framework where the CKM and PMNS complex phases are vacuum induced is presented. It consist in a Two Higgs Doublet Model with a $\mathbb{Z}_{2}$ symmetry which is softly broken, where the only source of CP-violation is the irremovable vacuum phase. This scenario requires non-vanishing but controlled Flavor Changing Neutral Couplings. Using the experimental data we are able to give a prediction to the lepton mixing matrix phase as well as to some flavor changing transitions ($c\rightleftarrows t$ and $d\rightleftarrows b$).
