We consider spin correlations in top-quark t-channel production and subsequent decay process, including anomalous Wtb interactions. We use formalism of spinors in Weyl's representation to compute squared amplitude of the process. It is found that unique kinematic functions stay near every combinations of anomalous couplings, so this fact could be used to obtain further limits on anomalous couplings.
