We have obtained spectropolarimetric observations of the four images of the gravitationally
lensed broad absorption line quasar H1413+117. The polarization of the microlensed
image D is significantly different both in the continuum and in the broad lines from
the polarization of image A which is essentially unaffected by microlensing. The observations
suggest that the continuum is scattered off two regions spatially separated and producing
roughly perpendicular polarizations. These results are compatible with a model in
which the microlensed polarized continuum comes from a compact region located in the
equatorial plane close to the accretion disk and the non-microlensed continuum from
an extended region located along the polar axis.
