We present a comprehensive update of the bounds on $R$-parity violating supersymmetric couplings from lepton-flavor- and lepton-number-violating decay processes. We consider $\tau$ and $\mu$ decays as well as leptonic and semileptonic decays of mesons. We present several new bounds resulting from $\tau$, $\eta$, and kaon decays and correct some results in the literature concerning $B$ meson decays.
