A Motion for Partial Summary Judgment on the Issue of Liability is a legal document filed in court by the party seeking to have a case resolved without a trial. This motion is specific to the state of Oklahoma and plays a crucial role in civil litigation cases. In Oklahoma, there are two main types of Motions for Partial Summary Judgment on the Issue of Liability: 1. Oklahoma Rule of Civil Procedure 13 Motion: Under Oklahoma law, Rule 13 allows parties to file a Motion for Partial Summary Judgment on the Issue of Liability. This motion can be filed during any stage of the proceedings but is often utilized before trial. The purpose of this motion is to request the court to determine liability, or fault, on a particular issue in the case. If the motion is granted, it means that the court has decided on the issue of liability, eliminating the need for a trial on that specific matter. 2.
