  The frequency of multiple systems and their properties are key constraints of
stellar formation and evolution. Formation mechanisms of very low-mass (VLM)
objects are still under considerable debate and an accurate assessment of their
multiplicity and orbital properties are essential for constraining current
theoretical models.
  Taking advantage of the Virtual Observatory capabilities, we looked for
comoving low and VLM binary (or multiple) systems using the Large Area Survey
of the UKIDSS LAS DR10, SDSS DR9, and the 2MASS Catalogues. Other catalogues
(WISE, GLIMPSE, SuperCosmos ...) were used to derive the physical parameters of
the systems.
  We report the identification of 36 low and VLM (~M0-L0 spectral types)
candidates to binary/multiple system (separations between 200 and 92000 AU),
whose physical association is confirmed through common proper motion, distance
and low probability of chance alignment. This new system list notably increases
the previous sampling in their mass-separation parameter space (~100). We have
also found 50 low-mass objects that we can classify as ~L0-T2 according to
their photometric information. Only one of these objects presents a common
proper motion high-mass companion.
  Although we could not constrain the age of the majority of the candidates,
probably most of them are still bound except four that may be under disruption
processes. We suggest that our sample could be divided in two populations: one
tightly bound wide VLM systems that are expected to last more than 10 Gyr, and
other formed by weak bound wide VLM systems that will dissipate within a few
Gyr.
