The bill amends 12 O.S. 2021, Section 2006, which pertains to the computation of time in civil procedure. It removes certain exemptions related to the computation of time, specifically deleting references to Sections 1148.4, 1148.5, and 1148.5A. The revised language clarifies that when calculating any period of time prescribed by law or court rules, the day of the act or event does not count, while the last day does count unless it falls on a legal holiday or a day when the court clerk's office is closed. Additionally, it specifies that for periods less than eleven days, intermediate legal holidays and days when the court clerk's office is closed will be excluded from the computation.

The bill also outlines provisions for enlarging time periods set by the court and establishes requirements for serving written motions and affidavits. It includes a provision that adds three days to the prescribed period when a notice or paper is served by mail, third-party commercial carrier, or electronic means. The act is set to take effect on November 1, 2026.
