We study the final state interaction in 3{pi} decay of meson resonances at the Excited Baryon Analysis Center (EBAC) of JLab. We apply the dynamical coupled-channels formulation which has been extensively used by EBAC to extract N{sup *} information. The formulation satisfies the 3{pi} unitarity condition which has been missed in the existing works with the isobar models. We report the effect of the 3{pi} unitarity on the meson resonance pole positions and Dalitz plot.
