The extraction of the \$BK^*\$ transition form factors from lattice data is
studied, applying non-relativistic effective field theory in a finite volume.
The possible mixing of \$K\$ and \$K\$ states is taken into account. The
two-channel analogue of the Lellouch-Lüscher formula is reproduced. Due to
the resonance nature of the \$K^*\$, an equation is derived, which allows to
determine the form factors at the pole position in a process-independent
manner. The infinitely-narrow width approximation of the results is discussed.
