I discuss the importance of disentangling the hadronic from the weak interaction effects among quarks, as a way to assessing the amount of the CP-violation in the Standard Model [and beyond]. I will point out the advantages and troubles to make that by means of lattice QCD, explain the current practice and the ways to improve it. Finally, the current status of the lattice calculation of the K_0-K_0bar and B_0-B_0bar mixing amplitudes in and beyond the Standard Model is presented.
