  The form factors of the $\Lambda_{b} \to N^\ast \ell^+ \ell^-$ decay are
calculated in the framework of the light cone QCD sum rules. In the
calculations the contribution of the negative parity $\Lambda_b^\ast$ baryon is
eliminated by constructing the sum rules for different Lorentz structures.
Furthermore the branching ratio of the semileptonic $\Lambda_b \to N^\ast
\ell^+ \ell^-$ decay is calculated. The numerical study for the branching ratio
of the $\Lambda_{b} \to N^\ast \ell^+ \ell^-$ decay indicates that it is quite
large and could be measurable at future planned experiments to be conducted at
LHCb.
