What section in there is applicable?
I read them all, it was not a loan agreement per defintion and this would not apply:
1335.05 Certain agreements to be in writing.
No action shall be brought whereby to charge the defendant, upon a special promise, to answer for the debt, default, or miscarriage of another person; nor to charge an executor or administrator upon a special promise to answer damages out of his own estate; nor to charge a person upon an agreement made upon consideration of marriage, or upon a contract or sale of lands, tenements, or hereditaments, or interest in or concerning them, or upon an agreement that is not to be performed within one year from the making thereof; unless the agreement upon which such action is brought, or some memorandum or note thereof, is in writing and signed by the party to be charged therewith or some other person thereunto by him or her lawfully authorized.
