We present our lattice calculation of the semileptonic form factors for the decays {ital D}{r arrow}{ital K}{sup *}, {ital D}{sub {ital s}}{r arrow}{phi}, and {ital D}{r arrow}{rho} using Wilson fermions on a 24{sup 3}{times}39 lattice at {beta}=6.0 with 8 quenched configurations. For {ital D}{r arrow}{ital K}{sup *}, we find for the ratio of axial form factors {ital A}{sub 2}(0)/{ital A}{sub 1}(0)=0.70{plus minus}0.16{sub {minus}0.15}{sup +0.20}. Results for other form factors and ratios are also given.
