Okla. Stat. tit. 67, § 67-20: Restoration of records by means of abstracts

It shall be the duty of the judge of the county court, or the

judge of the district court of any county in this state, in which

any public records have been lost or destroyed to examine into the

state of the records in such county, and in case he finds any

abstracts, copies, minutes or extracts from said records existing

after such destruction as aforesaid, and finds that said abstracts,

copies, minutes or extracts were fairly made before the destruction

of the records by any person, in the ordinary course of business,

and that they contain a material and substantial part of said

records, and, that such abstracts, copies, minutes and extracts tend

to show a connected chain of title to the land in said county, the

said judge shall certify the facts found by him in respect to such

abstracts, copies, minutes and extracts, and said judge, shall cause

all evidence produced as to said abstract books to be reduced to

writing, and shall cause all such evidence to be spread of record,

as a part of the order of said court.
