Except as otherwise provided in Section 4005 of this title, the owner of every vessel or motor in this state shall possess a certificate of title as proof of ownership of such vessel or motor.
Application for a certificate of title, whether an original or duplicate, may be made to any licensed operator. When application is made with a licensed operator, the application information shall be transmitted either electronically or by mail to Service Oklahoma by the licensed operator. If the application information is transmitted electronically, the licensed operator shall forward the required application along with evidence of ownership, where required, by mail. Where the transmission of application information cannot be performed electronically, Service Oklahoma is authorized to provide postage-paid envelopes to licensed operators for the purpose of mailing the application along with evidence of ownership, where required. Service Oklahoma shall upon receipt of proper application information issue an Oklahoma certificate of title. Such certificates may be mailed to the applicant. Upon issuance of a certificate of title, Service Oklahoma shall provide the appropriate licensed operator with confirmation of such issuance.
