    Dependence of the K(-)d scattering length on the different models of (K) over barN-pi Sigma interaction describing Lambda (1405) resonance in terms of one or two poles is investigated. The (K) over bar NN - pi Sigma N system is described by coupled- channel Faddeev equations in AGS form. The two-body (K) over barN - pi Sigma interaction models reproduce all existing experimental data on K(-) p scattering and K(-) p atom level shift. The comparison with several approximations, commonly used for such calculations, is done.
