Precise measurements of the top quark-Higgs boson Yukawa coupling may provide insights about the underlying mechanisms of Electroweak Symmetry Breaking. Measurements of Higgs boson production in association with top quarks provide a powerful probe of the top-Higgs Yukawa coupling. The current status of the search for ttH production in the 4lepton+Jets final state using the data collected by the ATLAS experiment at the center-of-mass energy 13 TeV in 2015 and 2016 is presented. The analysis is most sensitive to H->WW and H->ZZ decay channels and exploits the very good signal to background ratio in this final state.
