The measurement of the form factors of the kaon semileptonic decays have been the subject of a renewed interest in relation to the precision test of the CKM matrix element V_us. Moreover it has recently been pointed out that the value of the K_mu3 scalar form factor can be used to test the existence of right-handed quark currents coupled to the standard W boson. In this seminar I will review the experimental situation and report on a new high statistics measurement of the K_\mu3 decay done by the NA48 collaboration at CERN.
