A new approach to the analysis of three body decays is presented. Measurements of the S-wave K{pi} amplitude are made in independent ranges of invariant mass from threshold up to the upper kinematic limit in D+ {yields} K-{pi}+{pi}+ decays. These are compared with results obtained from a fit where the S-wave is assumed to have {kappa} and K{sub 0}*(1430) resonances. Results are also compared with measurements of K-{pi}+ elastic scattering. Contributions from I = (1/2) and I = (3/2) are not resolved in this study. If I = (1/2) dominates, however, the Watson theorem prediction, that the phase behaviour below K{eta}' threshold should match that in elastic scattering, is not well supported by these data. Production of K-{pi}+ from these D decays is also studied.
