We study possible crossing of the phantom divided barrier in a Lorentzinvariance violating dark energy model. Lorentz invariance violation which isachieved by introducing a vector field in the action, incorporates directly inthe dynamics of the scalar field and equation of state. This interestingfeature allows us to study phantom divided barrier crossing in the context ofLorentz invariance violation. We show that for suitable choice of parameterspace, equation of state can cross phantom divided barrier just by one scalarfield and Lorentz violating vector field controls this crossing.
