Okla. Stat. tit. 59, § 59-1151.16

Every applicant for a roofing contractor's registration who is a

nonresident contractor as defined by this act, by signing and filing

the application, appoints the Secretary of State as the applicant's

true and lawful agent upon whom may be served all lawful process in

any action or proceeding against such nonresident contractor for

construction projects performed in this state. Such appointment in

writing is evidence of the roofing contractor's consent that any

such process against the contractor which is so served upon the

Secretary of State shall be of the same legal force and effect as if

served upon the contractor personally within this state. Registered

foreign corporations, registered foreign limited liability

companies, foreign limited liability partnerships and foreign

limited partnerships entitled to do business in this state and

having a current registered agent and registered address on file in

the Office of the Secretary of State need not appoint the Secretary

of State as agent for service of process under this section. Within

ten (10) days after service of the summons upon the Secretary of

State, notice of such service with the summons and complaint in the

action shall be sent to the defendant roofing contractor at the

defendant contractor's last-known address by registered or certified

mail with return receipt requested and proof of such mailing shall

be attached to the summons. The Secretary of State shall keep a

record of all process served upon the Secretary of State under this

section, showing the day and hour of service. Whenever service of

process was made under this section, the court, before entering a

default judgment, or at any stage of the proceeding, may order such

continuance as may be necessary to afford the defendant contractor

reasonable opportunity to defend any action pending against the

defendant contractor.
