We analyse the impact of non-minimally flavour violating (NMFV) terms in the Lagrangian of the Minimal Supersymmetric Standard Model (MSSM) at the TeV scale on signatures related to squarks at the LHC. We begin with an extensive study of the corresponding parameter space by means of a Markov Chain Monte Carlo (MCMC) setup. This represents the first study of several non-zero NMFV elements in the MSSM. We present the results of this study with a special focus on the flavour-violating parameters and related observables at the LHC. Based on these results, we define benchmark points for future studies of NMFV effects at the LHC [JHEP 1511 (2015) 125]. We then discuss possibilities how to disentangle minimal and non-minimal flavour violation in Supersymmetry assuming the observation of squarks at the LHC. The reconstruction of the squark flavour sector from observed LHC event rates might rule out the MFV paradigm [work in progress]. We finally discuss the decay of a stop squark into a charm quark and a neutralino. This channel arises at the tree-level when allowing for the appropriate NMFV terms, and is therefore an interesting process to confront MFV and NMFV [work in progress].
