By solving the 5-body Faddeev-Yakubovsky equations in configuration space with realistic nuclear Hamiltonians we have studied the resonant states of 5 H isotope. Two different methods, allowing to bypass the exponentially diverging boundary conditions, have been employed providing consistent results. The existence of 5 H broad J π =1/2 + ,3/2 + ,5/2 + states as S-matrix poles has been confirmed and compared with the, also calculated, resonant states in 4 H isotope. We have established that the positions of these resonances only mildly depend on the nuclear interaction model.
