We examine the validity of the generalized factorization method and calculate the angular correlations in the charmful three-body baryonic decays of ${\overline{B}}^0\to \mathrm{\Lambda }\overline{p}{D}^{(*)+}$. With the timelike baryonic form factors newly extracted from the measured baryonic $B$ decays, we obtain $\mathcal{B}({\overline{B}}^0\to \mathrm{\Lambda }\overline{p}{D}^{+},\mathrm{\Lambda }\overline{p}{D}^{*+})=(1.85\pm 0.30,2.75\pm 0.24)\times {10}^{-5}$ to agree with the recent data from the Belle Collaboration, which demonstrates that the theoretical approach based on the factorization still works well. For the angular distribution asymmetries, we find ${\mathcal{A}}_{\theta }({\overline{B}}^0\to \mathrm{\Lambda }\overline{p}{D}^{+},\mathrm{\Lambda }\overline{p}{D}^{*+})=(-0.030\pm 0.002,+0.150\pm 0.000)$, which are consistent with the current measurements. Moreover, we predict that ${\mathcal{A}}_{\theta }({\overline{B}}^0\to p\overline{p}{D}^0,p\overline{p}{D}^{*0})=+0.04\pm 0.01$. Future precise explorations of these angular correlations at Belle and LHCb as well as super-Belle are important to justify the present factorization approach in the charmful three-body baryonic decays.
