Form factors of the weak ${\mathrm{\ensuremath{\Xi}}}_{c}\ensuremath{\rightarrow}\mathrm{\ensuremath{\Xi}}(\mathrm{\ensuremath{\Lambda}})$ transitions are calculated within light cone QCD sum rules. The pollution coming from contribution negative parity ${\mathrm{\ensuremath{\Xi}}}_{c}^{*}$ baryon is eliminated by considering combinations rules corresponding to different Lorentz structures. Having obtained form factors, branching ratios ${\mathrm{\ensuremath{\Xi}}}_{c}\ensuremath{\rightarrow}\mathrm{\ensuremath{\Xi}}(\mathrm{\ensuremath{\Lambda}})\ensuremath{\ell}\ensuremath{\nu}$ decays also calculated, and our predictions compared with results other approaches as well measurements done BELLE ALICE collaborations.
