In this contribution we consider varying Krall--type polynomials which are orthogonal with respect to a varying discrete Krall--type inner product. Our main goal is to give ladder operators for this family of polynomials as well as to find a second--order differential--difference equation that these polynomials satisfy. We generalize some results appeared recently in the literature.
