A faint companion galaxy (m_k=21.910.26 in the Vega system) that lies ~2.4" north of the QSO sightline has been clearly resolved by this high resolution imaging. The non-detection of this close companion by the previous deep R-band observation indicates that it has a red color (R-K)_Vega >3.3. This object has irregular morphology with two close components (separation ~0.3"). Given the small impact parameter (b=19.6 kpc, at z_lls=2.531), it might be a candidate galaxy giving rise to the Lyman Limit system absorption at z_abs=2.531 seen in the QSO spectrum. Careful subtraction of the PSF from the QSO image revealed the QSO host galaxy. We modelled in detail the host galaxy properties using the 2-D decomposition algrithm GALFIT, and find that QSO UM402 is hosted by a giant elliptical of m_k=20.19\pm0.15 and of a scalelength ~4 Kpc, as bright as other resolved hosts of radio-loud QSOs (RLQ) at similar redshift, although UM402 itself is radio quiet (RQQ). Meanwhile, this QSO falls within the scale relation on the black hole mass vs. host luminosity of the local and other high-z samples, showing no significant excess of M_BH/logL_V ratio at z~3.
