Okla. Stat. tit. 26 § 14-121.1
A registered voter whose application is on file and who lost or did not receive absentee ballots may apply for a second set of absentee ballots if more than seven (7) days have passed since the ballots were transmitted to the voter by the county election board. To receive a second set of ballots, the voter must swear or affirm that the voter lost or did not receive the original set of ballots for that election and that the voter will vote only one set of ballots. The Secretary of the State Election Board shall prescribe a form to be used for such application, although any written application setting forth substantially the same facts shall be valid. The written application for replacement ballots shall be personally signed by the voter and acknowledged before a notary public or witnessed as required on the affidavit for return of the original absentee ballots, and may be transmitted to the county election board in person by the voter, by United States mail or by an agent designated by the voter. The person transmitting such application on behalf of the voter may be anyone of the voter's choosing at least sixteen (16) years of age, provided said person is not employed by or related within the third degree of consanguinity or affinity to any person whose name appears on the ballot. No person may be the agent for more than one voter at any election. Such second ballot set shall be transmitted by the voter to the county election board in the same manner as provided in the original set.
