Very recently it was predicted the existence of a charged state near the$D_s\bar{D}^*/D^*_s\bar{D}$ threshold. This state, that we call $Z_{cs}^+$,would be the strange partner of the recently observed $Z_c^\pm(3900)$. Usingstandard techniques of QCD sum rules, we evaluate the three-point function forthe vertices $Z_{cs}^+ \, J/\psi \, K^+$, $Z_{cs}^+ \, \eta_c \, K^{*+}$ and$Z_{cs}^+ \, D_s^+\bar{D}^{*0}$ and we make predictions for the correspondingdecay widths in these channels.
