  Fluctuation relations are derived in systems where the spin degree of freedom
and magnetic interactions play a crucial role. The form of the non-equilibrium
fluctuation theorems relies in the assumption of a local balance condition. We
demonstrate that in some cases the presence of magnetic interactions violates
this condition. Nevertheless, fluctuation relations can be obtained from the
micro-reversibility principle sustained only at equilibrium as a symmetry of
the cumulant generating function for spin currents. We illustrate the
spintronic fluctuation relations for a quantum dot coupled to partially
polarized helical edges states.
