We calculate four-fermion decays of a Higgs boson via WW and/or ZZ intermediate states for Higgs masses below mW. We examine models with a doubly-charged Higgs boson H++ and show that the four-fermion decay is the dominant mode for a wide range of parameter space. Existing searches for H++ in Z decays have not looked for this mode. We also derive four-fermion decay rate for a neutral Higgs boson.
