We will discuss the definition and stability conditions of tame parahoric G-Higgs torsor, which is based on the stability condition for G-bundles given by Ramanathan. Under the stability condition, we can construct the moduli space of semistable tame parahoric G-Higgs torsors. Furthermore, the stability condition defined for parahoric G-Higgs torsors is an algebraic interpertation of the stability condition used to prove a version of Kobayashi-Hitchin correspondence for G-bundles on noncompact curves, which is first studied by Biquard, Garcia-Prada and Mundet.
