We have calculated the differential probability of the radiative decay, tau(-) --> upsilon(tau) + pi(-) + gamma, of the tau-lepton carrying an anomalous magnetic moment. Taking into account both the inner bremsstrahlung and the structure-dependent radiation contributions, we computed the double differential probability. Observables, which are particularly suitable for the full reconstruction of the vector and axial form factors, are identified and implications for the measurement of the anomalous magnetic moment of the tau-lepton are discussed.
