Lorentz invariance is among the most fundamental and tested symmetries in physics. Measurements from over two decades of experiments place stringent constraints on many Lorentz-violating interactions affecting the particles of the Standard Model. However, a large class of interactions inducing charged-lepton-flavor violation remains largely unexamined. In this talk, we discuss dominant Lorentz- and CPT-violating operators initiating flavor-changing tau and muon decays. Branching-ratio measurements from the MEG and BaBar collaborations allow several first constraints to be placed on flavor off-diagonal tau, muon, and electron coefficients for Lorentz violation. The outlook for improved constraints in future experiments is also discussed.
