Run-I results from the CMS collaboration show an excess of events in decay h → μτ e with a local significances 2.4σ. This could be first hint flavour violation Higgs sector. We summarise bounds on violating Yukawa couplings direct searches, low energy measurements and projected future experiments. discuss sensitivity upcoming HL-LHC runs lepton colliders measuring lepton-flavour using effective field theory framework. For we find limits BR(h ) eτ ≲ $$ \mathcal{O}(0.5)\% eμ) \mathcal{O}(0.02)\% . ILC center-of-mass 1 TeV expect eτ) to measurable down \mathcal{O}(0.2)\%
