The form factor ratios r_v = V(0)/A₁(0), r₂ = A₂(0)/A₁(0) and r₃ = A₃(0)/A₁(0) in the decay D⁺ → K̄^{(black star)0}ℓ⁺ ν_ℓ, K̄^{(black star)0} K^- π⁺ have been measured using data from charm hadroproduction experiment E791 at Fermilab. From 3034 (595) signal (background) events in the muon channel, we obtain r_v= 1.84 ± 0.11 ± 0.09, r₂ = 0.75 ± 0.08 ± 0.09 and, as a first measurement of r₃, we find 0.04 ± 0.33 ± 0.29. The values of the form factor ratios r_v and r₂ measured for the muon channel are combined with the values of r_v and r₂ that we have measured in the electron channel. The combined E791 results for the muon and electron channels are r_v = 1.87 ± 0.08 ± 0.07 and r₂ = 0.73 ± 0.06 ± 0.08.
