Abstract
The constraints of tree unitarity are applied to a general broken supersymmetric theory. These constraints give relations among the coupling constants for the coupling of the supersymmetric fermions to the W and Z bosons and relations between these couplings and the fermion masses. We also get bounds involving the coupling constants and the masses. For a specific model, where coupling constants are known, these can be used to set upper bounds on the masses of the supersymmetric particles. These bounds and the relations must be satisfied in any model where supersymmetry is broken at the tree level.
