We review the theory of meson decays to two lepton pairs, including the cases of identical as well as nonidentical leptons, as well as CP-conserving and CP-violating couplings. A complete lowest-order calculation of QED radiative corrections to these decays is discussed, and comparisons of predicted rates and kinematic distributions between tree-level and one-loop-corrected calculations are presented for both ${\ensuremath{\pi}}^{0}$ and ${K}^{0}$ decays.
