In this paper, we will analyze a time-dependent geometry in a massive theory of gravity. This will be done by analyzing Vaidya space-time in such a massive theory of gravity. As a gravitational collapse is a time-dependent system, we will analyze it using the Vaidya space-time in massive gravity. The Vainshtein and dRGT mechanisms were used to obtain a ghost-free massive gravity, and construct such time-dependent solutions. We also studied thermodynamical aspects of such a geometry. So, we calculated the important thermodynamical quantities for such a system and analyzed the thermodynamical behavior of such quantities.
