Neutron diffraction studies of CeT_{2}Al10 (T = \text{Ru} and Os), which shows an anomalous transition at T_{0} = 27 K for CeRu2Al10 and at 29 K for CeOs2Al10, have been carried out using single crystal samples of the compounds. In the ordered state below T_{0}, obvious superlattice reflections have been found, indicating the appearance of ordered magnetic moments. The magnetic structures of both compounds could be commonly explained with a propagation vector \mathbf{q}= (0, 1, 0), where collinear antiferromagnetic moments with magnitudes of 0.42(1) \mu_{\text{B}} for CeRu2Al10 and of 0.29(1) \mu_{\text{B}} for CeOs2Al10 are aligned along the c-axis.
