We report preliminary results on semileptonic form factors of $B_c\rightarrow \eta_c l\nu$ and $B_c\rightarrow J/\psi l\nu$ decays as well as the decay constant of $B_c$ meson. For the charm quark we use overlap fermions whereas a non-relativistic formulation with improved coefficients is utilized for the bottom quark on a background of three 2+1+1 flavours HISQ lattice ensembles generated by the MILC collaboration. For semileptonic form factors we use sequential source method and results are obtained by fitting two and three point correlators simultaneously as well as using ratio method.
