We study three-body decays of $\Lambda_c^{*}(2765) \to \Lambda_c^+\pi^+\pi^-$by using effective Lagrangians in a non-relativistic framework. We consider thesequential decays through $\Sigma_c(2455)\pi$ and $\Sigma_c^*(2520)\pi$ inintermediate states which are dominant contributions. The coupling constants inthe effective Lagrangians are computed in the quark model. We demonstrate thatthe ratio $R= \Gamma(\Lambda_c^*\to\Sigma_c^*(2520)\pi)/\Gamma(\Lambda_c^*\to\Sigma_c(2455)\pi)$ and angular correlations are sensitive to the spin andparity of $\Lambda_c^{*}(2765)$. Thus, the measurement of these observables inexperimental facilities such as Belle and LHCb can provide useful constraintsto determine the spin and parity of $\Lambda_c^{*}(2765)$.
