  The search for the production of the Higgs boson associated with a pair of
top quarks in the ATLAS experiment is presented. It focuses on Higgs bosons
decaying to $b\bar{b}$ and events containing two leptons (electrons and/or
muons). It uses 20.3 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}$ = 8 TeV
collected with the ATLAS detector at the LHC in 2012. No significant excess of
events is found and the 95% CL observed (expected) limit is 7.0xSM (4.3xSM).
After combining with the single lepton final state an observed (expected) limit
of 4.1xSM (2.6xSM) with a best fit of $\mu=1.7\pm1.4$ is obtained.
