  We study the coupling of the Lambda(1520)= Lambda* resonance to the \bar K*
vector meson and nucleon. This coupling is not directly measured from the
resonance decay, but is expected to be important in hyperon production
reactions, in particular for the exotic Theta+ production. We compute the
coupling in two different schemes, one in the chiral unitary model where the
Lambda* is dominated by the quasibound state of mesons and baryons, and the
other in the quark model where the resonance is a p-wave excitation in the
three valence quarks. Although it is possible to construct both models such
that they reproduce the \bar K N and pi Sigma decays, there is a significant
difference between the Lambda* \bar K* N couplings in the two models. In the
chiral unitary model $|g_{\Lambda^*\bar{K}^* N}| \sim 1.5$, while in the quark
model $|g_{\Lambda^*\bar{K}^* N}| \sim 10$. The difference of the results stems
from the different structure of the Lambda* in both models, and hence, an
experimental determination of this coupling would shed light on the nature of
the resonance.
