How do you vacate or challenge a default judgment within 30 days?

Short answer

In Oklahoma, file a motion to vacate within 30 days after the judgment is filed, identify a statutory ground for relief, and give notice to affected parties. A motion based on lack of valid service or lack of actual notice may be especially important in a default case, but the available procedure and deadline can depend on how service was attempted and when the judgment was filed.

Procedure within 30 days

Oklahoma law provides:

“On motion of a party made not later than thirty (30) days after a judgment, decree, or appealable order … has been filed with the court clerk, the court may correct, open, modify, or vacate” it.

The practical steps are:

1. Confirm the filing date. The ordinary 30-day period runs from filing of the judgment with the court clerk. If you did not prepare the judgment and the court records do not show that a required copy was mailed to you within three days, the statute may allow filing within 30 days after the earliest recorded mailing date.
2. File a motion to vacate in the same case. Within the 30-day period, use a motion under Sections 1031.1(B) and 1031, rather than the post-30-day petition procedure. The motion must state the specific grounds and supporting facts; attach affidavits or other evidence where useful.
3. Give notice to affected parties and request a hearing. Section 1031.1(B) expressly requires notice to affected parties. Follow the court’s local filing, service, and hearing procedures.
4. Support the motion with a proposed defense. Explain both why the judgment should be opened or vacated and what defense you would present if allowed to litigate. This is particularly useful where the court considers whether reopening the case would serve justice and cause hardship.

Grounds to assert

Section 1031 lists grounds on which a court may vacate or modify its judgment, including:

• No actual notice of the action when judgment was filed, as authorized by the service statute;
• Mistake, neglect, or omission of the clerk, or irregularity in obtaining the judgment;
• Fraud by the successful party in obtaining the judgment;
• Unavoidable casualty or misfortune preventing the party from defending; and
• Other specified circumstances, including certain errors involving minors or persons of unsound mind.

For a default judgment, first examine the return or proof of service, the summons, and the record of any required notice before default. If service was refused, Oklahoma’s service statute provides that a default judgment must be set aside on the prescribed motion or petition if the defendant demonstrates that an unauthorized person signed the return receipt or refused delivery. In Ferguson, the Oklahoma Supreme Court held that the trial court abused its discretion in refusing to vacate a default judgment where the record did not establish proper service or compliance with the statutory procedure after refused service.

A timely motion to vacate is reviewed for abuse of discretion. Oklahoma courts consider, among other things, that defaults are disfavored, whether the party had an opportunity to be heard, whether reopening would cause substantial hardship or delay, and whether leaving the judgment in place would work a serious injustice.

Watch the deadline and preserve appellate rights

If the 30 days have passed, Section 1031.1(C) generally requires a petition under Section 1033, unless all parties who appeared approve proceeding otherwise. Some service-specific provisions also impose their own limits. A motion to vacate does not itself guarantee that the judgment will be set aside, so calendar the appeal deadline separately and check whether the motion affects it under the applicable appellate rules.
