  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.
