0.9 μm CCD images and 2.2 μm slit scan observations reveal the double character of the infrared source Serpens - SVS20; the separation, position angle and brightness ratio are 1.″6, 10°, and Δm ≍ 1.6 mag respectively. The southern source is the brightest at both spectral ranges. At 0.9 μm the observed polarization of each component is p = 9.0 %, ⊙ = 155° and p = 10.4 %, ⊙ = 135° for SVS20-South and SVS20-North respectively. These results combined with 2.2 μm polarimetry and JHKLM photometry suggest that both SVS20 sources are in fact low mass, probably PMS, stars.
