  The presence of R-parity violating interactions may relieve the tension
between existing LHC constraints and natural supersymmetry. In this paper we
lay down the theoretical framework and explore models of dynamical R-parity
violation in which the breaking of R-parity is communicated to the visible
sector by heavy messenger fields. We find that R-parity violation is often
dominated by non-holomorphic operators that have so far been largely ignored,
and might require a modification of the existing searches at the LHC. The
dynamical origin implies that the effects of such operators are suppressed by
the ratio of either the light fermion masses or the supersymmetry breaking
scale to the mediation scale, thereby providing a natural explanation for the
smallness of R-parity violation. We consider various scenarios, classified by
whether R-parity violation, flavor breaking and/or supersymmetry breaking are
mediated by the same messenger fields. The most compact case, corresponding to
a deformation of the so called flavor mediation scenario, allows for the
mediation of supersymmetry breaking, R-parity breaking, and flavor symmetry
breaking in a unified manner.
