The CP violating asymmetry from the decay rates H±→W±h1 of charged Higgs bosons into the lightest neutral Higgs boson and a W± boson is calculated and discussed in the complex MSSM. The contributions from all complex phases are considered, especially from the top-squark trilinear coupling, which induces a large contribution to the CP asymmetry.
