## Abstract

Lattice efforts to compute matrix elements relevant to semi-leptonic form factors are reviewed. The emphasis is on D → K^{*} where the two groups seem to find appreciably different results for A_{2}(0)/A_{1}(0). Lattice measurements at the end-point region for both the 0^{-} and the 1^{-} final states are emphasized. All the lattice results seem to suggest that for D, D_{s} decays to 1^{-} final states, the A_{1} form factor at the endpoint is always close to unity. We note that the FNAL experiment E691 does not agree with lattice results for A_{1} at the endpoint; in addition it tends to disagree with our value for A_{2}(0)/A_{1}(0).
