  Upper and lower bounds are established on the Lambda_b -> Lambda_c
semileptonic decay form factors by utilizing inclusive
heavy-quark-effective-theory sum rules. These bounds are calculated to leading
order in Lambda_QCD/m_Q and alpha_s. The O(alpha_s^2 beta_0) corrections to the
bounds at zero recoil are also presented. Several form factor models used in
the literature are compared with our bounds.
