We study the contributions of the nonstandard neutrino interactions to the rare meson decays of K{sup +}{yields}{pi}{sup +}{nu}{nu} and D{sup +}{yields}{pi}{sup +}{nu}{nu}. We show that both decays could provide strong constraints on the free parameters in the nonstandard neutrino interactions. We point out that the branching ratio of D{sup +}{yields}{pi}{sup +}{nu}{nu} could be at the level of 10{sup -8}.
