• The most general form of the K_<13> current matrix element in the Duffin-Kemmer-Petiau (DKP) formalism is deduced. This is done by two methods: () An explicit evaluation of the DKP covariants and () by using only Lorentz invariance and the fact that the incoming and outgoing meson states are solutions of the DKP equation. The formal reduction of the matrix element is facilitated by introducing particular properties of the spin-0 algebra and fully exploiting the DKP consequent equation. We emphasize that (a) there are only two independent DKP K_<13> vector form factors, (b) there is only one independent DKP scalar form factor and (c) in, for example, the DKP K^*-pole model, there must exist a zero in the DKP current-divergence matrix element.
