Service Deadline Calculator

180-Day Service Deadline

Under 12 O.S. § 2004(I), a summons and petition must be served within 180 days after the case is filed. If service is not completed within this window, the court may dismiss the action without prejudice on its own motion or on motion of any party. Courts may grant extensions for "good cause shown," but waiting until the deadline approaches is risky. File extension motions early, and document all service attempts to demonstrate diligence.

This deadline applies to the initial service of process — getting the summons and petition into the defendant's hands. It does not apply to subsequent filings like motions or discovery requests.

20-Day Answer Deadline

Once a defendant is properly served, they typically have 20 calendar days to file an answer or other responsive pleading. This deadline is computed under 12 O.S. § 2006, which governs how time is calculated in Oklahoma civil procedure. If the final day falls on a weekend or court holiday, the deadline extends to the next business day. Defendants who fail to answer risk default judgment.

Service by Publication — 41-Day Minimum

When a defendant's whereabouts are unknown after diligent search, service by publication may be authorized. The notice must be published once per week for three consecutive weeks in a newspaper qualified under Oklahoma law. After the final publication date, at least 41 days must pass before a default judgment can be entered. Publication service is considered a last resort — courts require proof of diligent efforts to locate the defendant before granting leave to publish.

Motion Response Deadlines

Responses to motions are typically due within 15 days of service under standard Oklahoma civil procedure. However, always check the court's scheduling order and local rules, as some judges set different timeframes. Like answer deadlines, if the response deadline falls on a weekend or court holiday, it rolls to the next business day under the "next business day" rule.

Court Holidays Observed

This calculator accounts for the following Oklahoma court holidays: New Year's Day, Martin Luther King Jr. Day, Presidents Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Veterans Day, Thanksgiving Day and the day after, Christmas Eve, Christmas Day, and New Year's Eve. When a deadline falls on one of these holidays or a weekend, it extends to the next business day under 12 O.S. § 2006.
