In general, charged Higgs bosons H-+/- appear in nonminimal Higgs models. The H(+/-)W(-/+)Z vertex is known to be related to the violation of the global symmetry (custodial symmetry) in the Higgs sector. Its magnitude strongly depends on the structure of the exotic Higgs models which contain higher isospin SU(2)(L) representations such as triplet Higgs bosons. We study the possibility of measuring the H(+/-)W(-/+)Z vertex via single charged Higgs boson production associated with the W-+/- boson at the International Linear Collider (ILC) by using the recoil method. The feasibility of the signal e(+)e(-) -> (HW -/+)-W-+/- -> lvjj is analyzed assuming the polarized electron and positron beams and the expected detector performance for the resolution of the two-jet system at the ILC. The background events can be reduced to a considerable extent by imposing the kinematic cuts even if we take into account the initial state radiation. For a relatively light charged Higgs boson whose mass m(H+) is in the region of 120-130 GeV < m(W) + m(Z), the H(+/-)W(-/+)Z vertex would be precisely testable especially when the decay of H-+/- is lepton specific. The exoticness of the extended Higgs sector can be explored by using combined information for this vertex and the rho parameter.
