  Disintegrating multiple systems have been previously discovered from
kinematic studies of the $\it Hipparcos$ catalogue. They are presumably the
result of dynamical encounters taking place in the Galactic disk between
single/multiple systems. In this paper, we aim to expand the search for such
systems, to study their properties, as well as to characterize possible
low-mass ejecta (i.e. brown dwarfs and planets). We have assembled a list of 15
candidate systems using astrometry from the Tycho-Gaia astrometric solution
(later upgraded with $\it Gaia$ DR3), and here we present the discovery and
follow-up of 5 of them. We have obtained DECam imaging for all 5 systems and by
combining near-infrared photometry and proper motion, we searched for
ultra-cool ejected components. We find that the system consisting of TYC
7731-1951-1, TYC 7731-2128 AB, and TYC 7731-1995-1ABC?, contains one very
promising ultra-cool dwarf candidate. Using additional data from the
literature, we have found that 3 out of 5 disintegrating system candidates are
likely to be true disintegrating systems.
