In this paper, we carry out an extensive investigation of terrestrial planetary formation in inclined planetary systems at the late stage. We consider the OGLE-2006-BLG-109L system as a prototype. In the simulations, we show that the occurrence of terrestrial planets is common, in the final assembly stage. Moreover, we find that 40 per cent of the runs finally have one planet occupying the habitable zone. However, the numerical results also indicate that the inner region of the planetesimal disc, which ranges from ∼0.1 to 0.3 au, plays an important role in the development of terrestrial planets. By examining all the simulations, we note that the survivals are located either between 0.1 and 1.0 au or beyond 7 au, or at the 1 : 1 mean-motion resonance of OGLE-2006-BLG-109Lb at ∼2.20 au. These outcomes suggest that there might be a moderate possibility for inclined systems to harbour terrestrial planets, even planets in the habitable zone.
