Okla. Stat. tit. 12, § 12-1857: Agreement

A. An agreement contained in a record to submit to arbitration

any existing or subsequent controversy arising between the parties

to the agreement is valid, enforceable, and irrevocable except upon

a ground that exists at law or in equity for the revocation of a

contract.

B. If necessary, a court shall decide whether an agreement to

arbitrate exists or a controversy is subject to an agreement to

arbitrate.

C. An arbitrator shall decide whether a condition precedent to

arbitrability has been fulfilled and whether a contract containing a

valid agreement to arbitrate is enforceable.

D. If a party to a judicial proceeding challenges the existence

of, or claims that a controversy is not subject to, an agreement to

arbitrate, the arbitration proceeding may continue pending final

resolution of the issue by the court, unless the court otherwise

orders.
