Per Curiam.

Plaintiff was injured in an automobile accident on February 7, 1959 involving plaintiff's vehicle and one owned and operated by Clarence Ellington, who was then insured by defendant, Cosmopolitan Mutual Insurance Co. ("Cosmopolitan"). An action was commenced against Ellington in July, 1959. Cosmopolitan's attorney appeared for Ellington and answered. Various proceedings were had in that action, including the service of a bill of particulars, a physical examination and an examination of plaintiff before trial.

However, Ellington failed to appear to be examined, pursuant to plaintiff's notice of examination before trial. In May, 1961, plaintiff moved for summary judgment in the personal injury action. Cosmopolitan wrote to Ellington advising him of the motion for summary judgment and the necessity for submitting an affidavit in opposition. At the same time, Cosmopolitan advised Ellington that it would disclaim liability and its attorney would withdraw if Ellington did not co-operate in the preparation and execution of an affidavit to be submitted in opposition to the motion for summary judgment. Cosmopolitan also claims that an investigator was sent out to locate Ellington but that his efforts were fruitless, and no affidavit was obtained from Ellington.

Plaintiff was successful on his motion for summary judgment after Cosmopolitan had submitted its own affidavit in opposition, based on data obtained from its files. On appeal the order granting summary judgment was affirmed. ( Rosen v. Ellington, 15 A.D.2d 878.) Thereupon, Cosmopolitan disclaimed liability under its policy because of Ellington's alleged failure to co-operate.

The instant action was brought to determine whether Cosmopolitan had properly disclaimed, and, in addition, to declare plaintiff's rights against defendant, United States Fidelity Guaranty Company (USFG), under the provisions of an "uninsured driver" clause contained in a policy of insurance issued by that company to plaintiff. Upon plaintiff's motion for summary judgment in this action, Special Term held that Cosmopolitan had properly disclaimed and that USFG was not liable under its policy since there was insurance on Ellington's vehicle applicable on the date of the accident. Summary judgment was accordingly granted to the defendants.

In Wallace v. Universal Ins. Co. ( 18 A.D.2d 121, 125, affd. 13 N.Y.2d 978) this court, per BOTEIN, P.J., said: "It has been stated that to amount to a breach of the co-operation clause `the attitude of the assured must be one "of willful and avowed obstruction"' ( American Sur. Co. v. Diamond, 1 N.Y.2d 594, 599). The burden of proving the breach is placed on defendant by statute (Insurance Law, § 167, subd. 5). True, upon a showing by the insurer of an absence of the insured which remains unexplained despite reasonable efforts to locate the insured, `the burden of going forward with the proof and supplying the data necessary to repel the adverse inference, must rest on the assured' ( Rushing v. Commercial Cas. Ins. Co., 251 N.Y. 302, 304). In this case, however, defendant has not made any showing that would warrant placing such a burden upon plaintiff."

Special Term held that Cosmopolitan had, as a matter of law, sustained the burden, under subdivision 5 of section 167 Ins. of the Insurance Law, of demonstrating that reasonable efforts to locate the insured had been employed, and consequently granted summary judgment to Cosmopolitan. We disagree, and hold that the record presents a triable issue as to whether Cosmopolitan made reasonable efforts under the circumstances to locate and communicate with Ellington. That issue must be tried as it was in Wallace ( supra), in Allstate Ins. Co. v. Coe ( 21 A.D.2d 34), and in National Grange Mut. Ins. Co. v. Lococo ( 20 A.D.2d 785, affd. 16 N.Y.2d 585.)

The affidavits submitted by Cosmopolitan regarding the sending of letters and as to the visits by the investigator, Rollerson, do not demonstrate, as a matter of law, that proper and diligent efforts were utilized which were calculated to locate the insured and to obtain his co-operation. The affidavit of the investigator is cryptic in its averments and gives no informative details to demonstrate a meaningful investigation as to the whereabouts of the insured. These claimed efforts must be gone into more fully at a trial in order to test their efficacy.

As to defendant USFG, plaintiff's claim rests upon the provisions of an "uninsured driver" clause contained in a policy of insurance issued by that company to plaintiff. Upon receiving notice of disclaimer from Cosmopolitan, plaintiff promptly notified USFG. The insurance policy defined an "uninsured automobile" as one on which there is "no bodily injury liability insurance applicable at the time of the accident". Disclaimer by the insurer of the other automobile, subsequent to the time of the accident, does not make that automobile an uninsured automobile "at the time of the accident" within the terms of the policy. ( Matter of Berman [ Travelers Ind. Co.], 11 Misc.2d 291; Matter of American Nat. Fire Ins. Co. [ McCormack], 15 Misc.2d 692.) Cases relied on by plaintiff under sections 600 to 626 of the Insurance Law (Motor Vehicle Accident Indemnification Corporation Law) are inapplicable. That law became effective on January 1, 1959, while the uninsured indorsement, on which plaintiff relies, was issued on June 14, 1958. Special Term properly held that there was liability insurance applicable at the time of the accident, precluding plaintiff's claim against USFG.

The judgment and resettled order should therefore be modified, on the law, to the extent of denying summary judgment to defendant, Cosmopolitan, with costs and disbursements to plaintiff against defendant Cosmopolitan, and otherwise the judgment and resettled order should be affirmed, with costs and disbursements to defendant United States Fidelity Guaranty Company. Settle order on notice.
