Okla. Stat. tit. 67, § 67-11: County records destroyed replaced by other records

Whenever it shall appear that the records, or any material part

thereof, of any county in this state have been destroyed by fire or

otherwise, any map, plat, deed, conveyance, contract, mortgage, deed

of trust, or other instrument in writing affecting real estate in

such county, which has been heretofore recorded, or certified copies

thereof, may be recorded in the place of such county records; and in

recording the same the register of deeds shall record the

certificate of the previous record, and the date of filing for

record appearing in said original certificate so recorded shall be

deemed and taken as the date of the record thereof. And copies of

any such record, so authorized to be made under this section, duly

certified by the register of deeds of any such county, under his

seal of office, shall be received in evidence, and have the same

force and effect as certified copies of the original record.
