Okla. Stat. tit. 12A, § 2A-219
Oklahoma Code Comment
Except in a finance lease ( § 2A-103(1)(g)), and except as otherwise agreed, risk of loss in the absence of default by the other party remains with the lessor. This probably reflects prior Oklahoma law. 15 Oklahoma Statutes §§538(2) and 539(4) (repealed by H.B.1683) provided that a bailment for hire terminated when the greater part, or that part which was the material inducement to the lessee, of the thing hired perished from a cause other than the negligence of the lessee, or was destroyed. 15 Oklahoma Statutes § 545 (also repealed), which seemed to absolutely require return of the personal property hired, should be read as consistent with the earlier sections, and thus as consistent with this section of Article 2A. Then, too, in the sales area, absent agreement, prior Oklahoma law allocated risk of loss on the basis of title, and the result of that approach generally is consistent with the rule of this section. See Oklahoma Code Comment to 12A Oklahoma Statutes § 2-509.
When one of the parties to the lease is in default, risk of loss is governed instead by § 2A-220 and essentially is allocated to the defaulting party. This approach appears consistent with that of 15 Oklahoma Statutes § 536 (repealed), and with that of 15 Oklahoma Statutes § 456, which provides that a bailee is responsible for any damage to the thing bailed during wrongful use of the goods unless the damage was inevitable.
Loss or damage due to the negligence of the lessee where the risk of loss remains on the lessor is to be distinguished. Article 2A treats any obligation of the lessee to care for the leased goods as an aspect of the lessor's reversionary rights which Article 2A, except in a few instances and in the absence of agreement, leaves to law outside the UCC as a part of the general law of property or other applicable law. See 12A Oklahoma Statutes § 1-103 and Official Comment to § 2A-525. But see § 2A-532. In the absence of agreement therefore, the lessee must under 15 Oklahoma Statutes § 466 exercise ordinary care. See Kesterson & Telle v. Marlow, 161 P. 186 (Okla.1917), involving a rented piano. In some instances under other law a greater duty may be involved. See 15 Oklahoma Statutes § 464. However, it would appear that a higher, but not a lesser, degree of care may be provided by the agreement of the parties. See Chambers v. Morgan, 671 P.2d 89 (Okla App. 1983); Oklahoma Petroleum & Gasoline Co. v. Winship, 200 P. 844 (Okla.1921); and Scott Auto & Supply Co. v. McQueen, 226 P. 372 (Okla.1924). In any event, for certainty the lease agreement should stipulate the condition of the goods to be returned to the lessor and the lessee's duty with respect to them during the term of the lease.
The 1991 amendments make no specific chance here.
