  We analyze the flavor structure of the trilinear couplings in the different
theoretical models of SUSY breaking. We generically obtain A_{ij}= A^L_i +
A^R_j in all the models examined. In fact, this is the rigorous form when SUSY
breaking effects appear through the Kahler metric of chiral fields or through
wave-function renormalization. Indeed, the low-energy phenomenological
requirements from the absence of charge and color breaking minima and the
measurements in flavor changing neutral current (FCNC) observables strongly
favor this restricted form of the trilinear matrices. As a straightforward
consequence, the number of unknown parameters associated with the trilinear
couplings is decreased in a factor of 2.
