The authors discuss the calculation of the evolution kernels {Delta}W{sub zeta}(X,Z) for the leading-twist nonforward parton distributions G{sub zeta}(X,t) sensitive to parton helicities. They present their results for the kernels governing evolution of the relevant light-ray operators and describe a simple method allowing to obtain from them the components of the nonforward kernels {Delta} W{sub zeta}(X,Z).
