  We consider the stochastic divergence-free continuity equations with
Ladyzhenskaya-Prodi-Serrin condition. Wellposedness is proved meanwhile
uniqueness may fail for the deterministic PDE. The main issue of uniqueness
realies on stochastic characteristic method and the generalized
Ito-Ventzel-Kunita formula. Moreover, we prove a stability property for the
solution with respect to the initial datum.
