We study singular fractional systems of nonlinear differential equations involving 3n-Caputo derivatives. We investigate existence and uniqueness results using the contraction mapping principle. We also discuss the existence of at least one solution by means of Schauder fixed point theorem. Moreover, we define and discuss the Ulam-Hyers stability and the generalized Ulam-Hyers stability of solutions for such systems. To illustrate the main results, we present some examples.
