We present the influence of local ordering on the electronic and magnetic properties of Heusler-type alloys. The band structure and magnetic moments are calculated by ab initio spin-polarized tight binding linear muffin-tin orbital method. The calculated electronic density of states for Pd_{2}TiAl alloy is similar to ultraviolet photoelectron spectroscopy measurements. The self-consistent band calculations showed that the density of states at the Fermi level in Ni_{2}(Nb_{(1-x)}Ti_{x})Sn and Ni_{2}(Nb_{(1-x)}Ta_{x})Sn alloys decreased with the increase in Ti or Ta concentration. The total and local magnetic moments in ordered Rh_{2}TMSn (TM = Mn, Fe, Co, Ni, Cu) and Rh_{2}MnX (X = Al, Ga, In, Ge, Sb, Pb) Heusler-type alloys are calculated. The difference between theoretical and experimental results can be connected to the partial disorder in the samples.
