The magnetic ordering in Ni_{1-x}Cu_{x}MnSb alloys changes from ferromagnetic (x=0) to antiferromagnetic (x=1). The X-ray and neutron diffraction showed that the systems crystallise in C1_{b} type structure. We present an influence of the local chemical ordering on the electronic and magnetic properties of Ni_{1-x}Cu_{x}MnSb alloys. The band structure and the magnetic moments were calculated by the spin-polarised linear muffin-tin orbital in the atomic sphere approximation method for the experimental values of the lattice parameters. The magnetic moment of Mn increases from 3.8 μ_{B} for x=0 to 4.18 μ_{B} for x=1.
