We study the potential of a future e{sup +}e{sup {minus}} collider for the search of anomalous {gamma}t{bar t} and Zt{bar t} couplings, assuming that CP invariance holds. This is done in a model-independent way, considering that all six possible couplings do appear. Two experimental situations are envisaged; with and without e{sup {plus_minus}} beam polarization. Observability limits in the form of domains in the six-dimensional parameter space are established. Illustrations for specific constrained models are also presented and implications for new physics searches are discussed. {copyright} {ital 1997} {ital The American Physical Society}
