We discuss the computation of form factors for semi-leptonic decays of B-, B s -mesons in lattice QCD. Considering in particular the example of the static B s form factors we demonstrate that after nonperturbative renormalization the continuum limit can be taken with confidence. The resulting precision is of interest for extractions of V ub . The size of the corrections of order 1/m b is just estimated at present but it is expected that their inclusion does not pose significant difficulties.
