Lepton flavor violation is not allowed in the Standard Model (SM), yet it has been observed in the neutrino sector. The physics responsible for neutrino oscillations and masses is still unknown and it may allow charged lepton flavor violation (cLFV). Evidence for cLFV processes, strongly suppressed according to the SM, would shed light on the nature of New Physics. cLFV has been widely investigated but processes involving the top quark and the Higgs boson have become directly accessible only recently at the ATLAS and CMS experiments. The results of the latest ATLAS searches and their interpretation will be presented, with particular attention to the top-quark sector.
