We investigate the a(0)pieta-vertex in the framework of light-cone QCD sum rules. We estimate the coupling constant g(a0pieta) which is an essential ingredient in the analysis of physical processes involving a(0)(980) meson. We determine the decay width of the a(0) --> pi(0)eta decay and compare our result with experimental value.
