Brown dwarf binary systems offer the unique opportunity to measure some of the underlying physical characteristics, like, e.g., the mass. In addition, the individual components of brown dwarf binaries are expected to be coeval and have the same chemical composition. This provides crucial constraints on any (evolutionary) model by greatly reducing the number of free parameters. Finally, brown dwarf binary statistics should shed light on the origin of brown dwarfs and possible formation mechanisms and environments. We summarize on-going surveys for brown dwarf binaries, and present first results of follow-up studies.
