Context. Some observations indicate that the Milky Way has two inner components, a bulge and a long bar, which present a misalignment of Δα ≃ 20° that is against the predictions of some theoretical models that are based on numerical simulations. Aims: We wish to determine whether this misalignment between the bar and the bulge can be observed in barred galaxies other than the Milky Way. Methods: Each galaxy of our sample was decomposed based on its Ks-band 2MASS image by fitting and modelling in a three-dimensional (3D) space the following components: a disc, a bar, and a bulge. The χ2 goodness-of-fit estimation allowed retrieving the best-fit angle values for the bar and the bulge to detect any misalignment. Results: From the 3D decomposition of six barred galaxies, we have detected at least three galaxies (NGC 2217, NGC 3992, and NGC 4593) that present a significant misalignment between the bar and the bulge of Δα> 20°.
