The recoil retardation effect in the K^\ensuremath-d scattering length is studied. Using the nonrelativistic effective field theory approach, it is demonstrated that a systematic perturbative expansion of the recoil corrections in the parameter \ensuremathξ=MK/mN is possible in spite of the fact that K^\ensuremath-d scattering at low energies is inherently nonperturbative due to the large values of the KN scattering lengths. The first-order correction to the K^\ensuremath-d scattering length due to single insertion of the retardation term in the multiple-scattering series is calculated. The recoil effect turns out to be reasonably small even at the physical value of MK/mN\ensuremath≃0.5.
