  We present millimeter-wave continuum images of four wide (separations 210-800
AU) young stellar binary systems in the Taurus-Auriga star-forming region. For
all four sources, the resolution of our observations is sufficient to determine
the mm emission from each of the components. In all four systems, the primary
star's disk has stronger millimeter emission than the secondary and in three of
the four, the secondary is undetected; this is consistent with predictions of
recent models of binary formation by fragmentation. The primaries'
circumstellar disk masses inferred from these observations are comparable to
those found for young single stars, confirming that the presence of a wide
binary companion does not prevent the formation of a protoplanetary disk. Some
of the secondaries show signatures of accretion (H-alpha emission and K - L
excesses), yet their mm fluxes suggest that very little disk mass is present.
