(a) An "arbitration agreement" is an agreement by the parties to submit to arbitration all or certain disputes which have arisen or which may arise between them in respect of a defined legal relationship, whether or not contractual. An arbitration agreement may be in the form of an arbitration clause in a contract or in the form of a separate agreement.
(b) The arbitration agreement shall be in writing. An agreement is in writing if it is contained in a document signed by the parties or in an exchange of letters, telex, telegrams, facsimile transmission, or other means of telecommunication which provide a record of the agreement, or in an exchange of statements of claim and defense in which the existence of an agreement is alleged by one party and not denied by another. The reference in a contract to a document containing an arbitration clause constitutes an arbitration agreement provided that the contract is in writing and the reference is such as to make that clause part of the contract.
(c) Such arbitration agreement shall be valid, enforceable and irrevocable, except with the consent of all the parties, without regard to the justiciable character of the controversy. (1991, c. 292.)
