We review a lattice strategy how to non-perturbatively determine the coefficients in the HQET expansion of all components of the heavy-light axial and vector currents, including \(1/m_h\)-corrections. We also discuss recent preliminary results on the form factors parameterizing semi-leptonic B-decays at the leading order in \(1/m_h\).
