  The Split-Family supersymmetry is a model in which the sfermion masses of the
first two generations are in $\mathcal{O}(100\text{-}1000)$ GeV while that of
the third one is in $\mathcal{O}(10)$TeV. With such a hierarchical spectrum,
the deviation of the muon $g-2$ and the observed Higgs boson mass are explained
simultaneously. In this paper, we revisit the Split-Family SUSY model in light
of the updated LHC constraints. We also study the flavor changing neutral
current problems in the model. As we will show, the problems do not lead to
stringent constraints when the Cabibbo-Kobayashi-Maskawa matrix is the only
source of the flavor mixing. We also study how large flavor mixing in the
supersymmetry breaking parameters is allowed.
