Possibility of using the polarized nucleus target for testing the non-standard properties of fermionic dark matter is considered. It is assumed that the incoming dark matter scatters on the polarized nuclei in the presence of vector, axial, scalar and tensor interactions. The scalar and tensor couplings are assumed to be complex numbers. Various types of measurement settings are tested depending on the assumptions regarding dark matter polarization and measurement of the recoil nucleus spin. In particular we address the question of finding and distinguishing effects of theoretically possible scenarios in which mixed triple products among various polarization vectors, the momenta of incoming dark matter and of recoil nucleus appear in the cross section. Their presence would indicate the possibility of time reversal symmetry violation in the polarized dark matter-nucleus scattering. Our considerations are model-independent and carried out in the non-relativistic dark matter and recoiled nucleus limit.
