The π+, K+ and K̄0 charge radii and form factors in the time-like region are analysed in an effective lagrangian context. This lagrangian, written in terms of the pseudoscalar, vector and photon fields, incorporates Vector Meson Dominance ideas and the main features of flavour symmetry. A reasonable description of the data is achieved.
