I agree with my colleagues that the order of the Supreme Court should be reversed but I do so for a different *459reason. It is well settled that the terms and conditions of underinsurance arbitration are controlled by the arbitration clause in the policy applicable to underinsurance. Unfortunately, Allstate Insurance Company (hereinafter Allstate) has not included the underinsurance endorsement in the record, but has included several sheets entitled "Endorsements (New York)” which purports in Section VI to replace language for the second paragraph of the arbitration provision. However, we do not know what that original arbitration provision states.
In paragraph seventh of the complaint, Allstate purports to quote from Part IV, Section I of the policy issued to their insured in this case. The defendant has denied that allegation and argues on this appeal that such a provision does not exist. The only policy in this record was submitted by the defendant and does not contain the arbitration clause referred to in the complaint. I agree with the defendant that Allstate has failed to defeat the defendant’s motion for summary judgment (see, Freedman v Chemical Constr. Corp., 43 NY2d 260).
Since the basic underinsurance clause is not in the record, I cannot conclude that Matter of Eckart v Aetna Cas. & Sur. Co. (208 AD2d 533) is in any way applicable. In Eckart, it appears that the possibility of a trial de novo was limited to situations in which common-law arbitration was employed. Without the entire underlying arbitration clause, we do not know if that is the situation in this case.
