To enter a family violence protective order a Texas court must find that family violence (1) has occurred and, (2) is likely to occur in the future. TFC 81.001.   Of the two prongs, the harder to prove in most cases is that violence is likely to occur in the future.  How do you prove a future event? In re Epperson, 213 S.W.3d 541 (Tex.App.-Texarkana 2007.) implies you can relay on prong one alone if the facts are sufficient.  The opinion states “oftentimes, past is prologue; therefore, past violent conduct can be competent evidence which is legally and factually sufficient to sustain the award of a protective order.”  In short if you have enough or prong one, you have proved prong two.
