Semileptonic decays of polarized τ leptons are investigated. The most general angular distribution of three meson final states (τ→ ππν, Kπν, πππν, Kππν, KKπν, KKKν, ηππν, …) is discussed. It is shown, that the most general distribution can be characterized by 16 structure functions, most of which can be determined in currently ongoing high statistics experiments. Emphasis is put on τ decays in e+e- experiments where the neutrino escapes detection and the τ rest frame cannot be reconstructed. The structure of the hadronic matrix elements, based on CVC and chiral lagrangians, is discussed.
