We discuss two aspects of the supersymmetry currents in the presence of symmetry breaking. First, we find that the algebra of supersymmetry charges is affected by the breaking. We will argue that this is also the case if the supersymmetry is realized in a spontaneously broken way. Secondly, we show that amplitudes that contain one supersymmetry current can be regularized consistently if the current is modified in a way that follows from our regularization scheme.
