Okla. Stat. tit. 15, § 15-19: Disaffirmance of minor's contract

In all cases other than those specified herein, the contract of

a minor may be disaffirmed by the minor himself, either before his

majority or within one (1) year's time afterwards; or, in case of

his death within that period, by his heirs or personal

representatives. Provided, that any minor between the ages of

sixteen (16) and eighteen (18) who has paid for any repairing,

supplying or equipping on any type of a motor vehicle may disaffirm

said contract in like manner only by restoring the consideration to

the party from whom it was received.
