Considering the Cabibbo-Kobayashi-Maskawa matrix, color suppression, diquark correlation, and the kinematical condition, we show that the final meson-baryon state should be in a pure $I=0$ combination, when the meson-baryon invariant mass is small. Because the $I=1$ contamination usually makes it difficult to analyze $\\mathrm{\\ensuremath{\\Lambda}}$ resonances directly from experiments, the ${\\mathrm{\\ensuremath{\\Lambda}}}_{c}$ decay is an ideal process to study $\\mathrm{\\ensuremath{\\Lambda}}$ resonances. Calculating the final-state interaction by chiral unitary approaches, we find that the $\\ensuremath{\\pi}\\mathrm{\\ensuremath{\\Sigma}}$ invariant mass distributions have the same peak structure in the all charge combination of the $\\ensuremath{\\pi}\\mathrm{\\ensuremath{\\Sigma}}$ states related to the higher pole of the two poles of the $\\mathrm{\\ensuremath{\\Lambda}}(1405)$.
