The new ATLAS search for ttH asdociated production with multi-lepton final states will be presented. The search targets Higgs boson decays to WW, ZZ and $\tau\tau$, and relies on final states with two same-sign, three or four leptons, and includes final states with hadronically decaying taus. The earlier CMS analysis targetting the same final state will also be discussed and similarities and differences between the two analyses will be highlighted.
