  Studying the semileptonic decays of charmed particles is prominent in testing
the standard model of particle physics. Motivated by recent experimental
progress in weak decays of the charm baryon sector, we study the form factors
of $\Lambda_c \to \Lambda \ell^+ \nu$ transition on two flavor lattices. We
compute two- and three-point functions, extract the dimensionless projected
correlators, and combine them to form the Weinberg form factors. In the zero
transferred momentum limit $f_1$, $f_2$ and $g_1$ form factors are found to be
in agreement with other models, furthermore $f_3$ and $g_3$ form factors are
comparable to model determinations. The $g_2$ form factor, on the other hand,
is found to be mildly larger. We also evaluate the helicity form factors, which
is consistent with the previous lattice studies.
