Run-I results from the CMS collaboration show an excess of events in the decay h -> mu tau(e) with a local significances of 2.4 sigma. This could be the first hint of flavour violation in the Higgs sector. We summarise the bounds on the flavour violating Yukawa couplings from direct searches, low energy measurements and projected future experiments. We discuss the sensitivity of upcoming HL-LHC runs and future lepton colliders in measuring lepton-flavour violating couplings using an effective field theory framework. For the HL-LHC we find limits on BR (h -> mu tau) and BR (h -> e tau) less than or similar to Omicron(0.5)% and on BR (h -> e mu) less than or similar to Omicron (0.02)%. For an ILC with center-of-mass energy of 1TeV we expect BR (h -> e tau) and BR (h -> mu tau) to be measurable down to Omicron (0.2)%.
