CERTIFICATE OF SERVICE

State of Oklahoma — District Court

JURISDICTION NOTE: This Certificate of Service template is designed for use in Oklahoma state court civil proceedings governed by Title 12 of the Oklahoma Statutes and the Oklahoma Pleading Code. For cases in the U.S. District Courts for the Northern, Eastern, or Western Districts of Oklahoma, consult the Federal Rules of Civil Procedure and applicable local rules.

OKLAHOMA SERVICE LAW — QUICK REFERENCE

12 O.S. § 2005(A) — Documents Requiring Service

Every pleading subsequent to the original petition, every written motion other than one which may be heard ex parte, every written notice, appearance, demand, offer of judgment, and similar paper must be served upon each of the parties.

Service upon a represented party is made upon the attorney of record unless the court orders service upon the party.

12 O.S. § 2005(B) — Permitted Methods of Service

Service of papers (other than original process) may be made by:

1. Delivery — Handing a copy to the attorney or party; leaving a copy at the attorney's office with a clerk or other responsible person; or leaving at the attorney's or party's residence with a person of suitable age and discretion
2. Mail — Mailing to the last known address
3. Facsimile — Transmitting via fax if authorized and the recipient has a fax number on file
4. Electronic Means — Transmitting by email or other electronic means with the written consent of the recipient (§ 2005(B)(3))
5. Court-approved e-filing portal — Use only if available for this court, case, and filer; confirm the portal's recipient-specific service record before certifying electronic service

12 O.S. § 2006(E) — Mail Extension (3 Days)

Whenever a party must act within a prescribed period after service, and service is by mail, 3 days are added to the prescribed period. Oklahoma follows the same 3-day mail extension rule as federal practice.

Oklahoma E-Filing — Check the Court and Recipient

Confirm the current filing portal, whether this case type and filer may use it, and whether its notice completes service on each intended recipient. Oklahoma County's Court Clerk says its new state e-filing system is currently available to attorneys and state agencies. Save the filing receipt and recipient-specific service confirmation. Serve anyone not confirmed as served through the portal by an authorized separate method and record that method below.

Electronic / Email Service — § 2005(B)(3)

Service by electronic means (including email) requires the written consent of the party or their attorney. Written consent documentation must be maintained in the attorney's file. Without consent, email service is not valid.

Service on Self-Represented (Pro Se) Parties

For a self-represented recipient, verify that the court's current portal actually permits electronic service on that person. If it does not, use another authorized method and record it below; do not infer service from filing alone.

District Court Variations

Local administrative orders may affect e-filing and service requirements. Check the applicable court clerk's current filing instructions and orders before certifying service.

OKLAHOMA PRACTITIONER NOTES

Response Deadline Calculation — 12 O.S. § 2006(E)

E-Filing Portal

Check the current portal and filing order for the specific court and case type. Oklahoma County directs eligible attorneys and state agencies to the new state portal at efile.oscn.net; that county's guidance does not establish availability or service effect elsewhere. Keep filing receipts and recipient-specific service records.

Certificate of Service on Discovery

Oklahoma follows the practice of serving discovery requests and responses on all parties. A certificate of service is required for all served discovery documents. Discovery is generally not filed with the clerk unless attached to a motion or ordered by the court.

Confidential Personal Information — Oklahoma Supreme Court Rule 31

Before serving documents electronically or filing publicly, redact personal identifiers (Social Security numbers, financial account numbers, dates of birth of minors, home addresses) consistent with Oklahoma Supreme Court rules and local administrative orders.

Domestic Violence / Protective Order Cases

In cases involving protective orders or domestic violence, special service rules and confidentiality protections apply. Consult the applicable provisions of 22 O.S. § 60.2 et seq. and the court's standing orders.

Attorney Withdrawal and Substitution

When an attorney has withdrawn or new counsel has entered an appearance, verify the current attorney of record before completing service. Serving a former attorney does not constitute valid service.
