This paper studies the very weak solution to the steady MHD type system in a bounded domain. We prove the existence of very weak solutions to the MHD type system for arbitrary large external forces $ ({\bf f},{\bf{g}}) $ in $ L^r({\Omega})\times [X_{\theta',q'}({\Omega})]' $ and suitable boundary data $ ({\mathcal B}^0,{\mathcal U}^0) $ in $ W^{-1/p,p}({\partial}{\Omega})\times W^{-1/q,q}({\partial}{\Omega}) $, under certain assumptions on $ p,q,r,\theta $. The uniqueness of very weak solution for small data $ ({\bf f},{\bf{g}},{\mathcal B}^0,{\mathcal U}^0) $ is also studied.

Keywords: Steady MHD type, existence, uniqueness, very weak solutions.
