Okla. Stat. tit. 49, § 5
Every notary shall provide a notarial seal containing the notary's name and county of residence or county of employment, if the notary is a non-resident. This seal may be either a metal seal which leaves an embossed impression or a rubber stamp used in conjunction with a stamp pad and ink. Each notary shall authenticate all official acts, attestations and instruments with this seal; and shall add to the notary's official signature the date of expiration of his or her commission as such notary public. If a rubber stamp is used, this date may be a part of the stamp. If any notary public shall neglect or refuse to attach to the notary's official signature the date of expiration of the notary's commission, the notary shall be deemed guilty of a misdemeanor, and upon conviction thereof shall be fined in any sum not exceeding Fifty Dollars ($50.00).
