  We present one-loop formulas for the decay of CP-odd Higgs $A^0 \rightarrow
\ell \bar{\ell} V$ with $\ell \equiv e, \mu$ and $V\equiv \gamma, Z$ in Higgs
Extensions of the Standard Model, considering two higgs doublet model with a
complex (and real) scalar, two higgs doublet model as well as triplet higgs
model. Analytic results for one-loop amplitudes are expressed in terms of
Passarino-Veltman functions following the standard notations of {\tt
LoopTools}. As a result, physical results can be generated numerically by using
the package. In phenomenological results, the total decay widths and the
differential decay rates with respect to the invariant mass of lepton pair are
analyzed for two typical models such as two higgs doublet model and triplet
higgs model.
