In this paper, we discuss several problems related to the neutral fractional Volterra-Fredholm integro-differential systems in Banach spaces. Existence of the Schaefer's fixed point and Ulam-Hyers-Rassias stability properties for the fixed point problem will be discussed. Some results are presented, under appropriate conditions, and some open questions are pointed out. Our results extend recent results given for \(\psi\)-fractional derivative.
