Okla. Stat. tit. 12, § 12-655: Petition for new trial on grounds discovered more than 10

days after judgment, decree, or appealable order was filed.

Where the grounds for a new trial could not with reasonable

diligence have been discovered before but are discovered more than

ten (10) days after the judgment, decree, or appealable order was

filed, or where the impossibility of preparing a record for an

appeal, without fault of the complaining party, arose more than ten

(10) days after the judgment, decree, or appealable order was filed,

the application may be made by petition filed in the original case,

as in other cases, within thirty (30) days after such discovery or

occurrence; on which a summons shall issue, be returnable and

served, or publication made, as in the beginning of civil actions,

or service may be made on the attorney of record in the original

case. The facts stated in the petition shall be considered as

denied without answer, and the case shall be heard and summarily

decided after the expiration of twenty (20) days from the date of

service and not more than sixty (60) days after service, and the

witnesses shall be examined in open court, or their depositions

taken as in other cases; but no petition shall be filed more than

one (1) year after the filing of the final judgment.
