Kinematic studies of the Hipparcos catalogue have revealed associations thatare best explained as disintegrating multiple systems, presumably resultingfrom a dynamical encounter between single/multiple systems in the field (Li etal. 2009). In this work we explore the possibility that known ultra-cool dwarfsmay be components of disintegrating multiple systems, and consider theimplications for the properties of these objects. We will present here themethods/techniques that can be used to search for and identify disintegratingbenchmark systems in three database/catalogues: Dwarf Archive, the HipparcosMain Catalogue, and the Gliese-Jahrei{\ss} Catalogue. Placing distanceconstraints on objects with parallax or colour-magnitude information fromspectrophotometry allowed us to identify common distance associations. Propermotion measurements allowed us to separate common proper motion multiples fromour sample of disintegrating candidates. Moreover, proper motion and positionalinformation allowed us to select candidate systems based on relative componentpositions that were tracked back and projected forward through time. Using thismethod we identified one candidate disintegrating quadruple association, andtwo candidate disintegrating binaries, all of them containing one ultra-cooldwarf.
