We study the influence of the D*s0(2317)+ resonance in the decay Bc → J/ψKD. In this process, we consider that the Bc meson decays first into J/ψ and the quark pair cs̄, and then the quark pair hadronizes into DK or Dsη components. The final state interaction, generating the D*s0(2317)+ resonance, is described by the chiral heavy meson unitary approach. With the parameters chosen in order to match the pole position of the D*s0(2317)+, we obtain the DK invariant mass distribution of the decay Bc → J/ψDK, and also the rate for Bc → J/ψD*s0(2317). We predict the ratio of these two magnitudes. This decay mechanism has not been measured yet, and it would provide insight about the nature of this resonance.
