In these proceedings we present results for the $t\bar{t}H$ process in the dileptonic decay channel at the Large Hadron Collider. We discuss a possible extension of the Standard Model of particle physics to allow for a $\mathcal{CP}$-odd component in the top-Higgs Yukawa interaction. Particular emphasis is placed upon the importance of higher-order corrections and full off-shell effects and on how these depend on the $\mathcal{CP}$-state of the Higgs boson. In addition, we also discuss Higgs-boson decays for the Standard Model case.
