Okla. Stat. tit. 12A, § 2-501
Oklahoma Code Comment
This section introduces a new concept into sales law, and is therefore difficult to compare with previous Oklahoma law. By this section, a "special interest" which is elaborated upon in the following sections, and an "insurable" interest is obtained by "identification" of the goods. The term "identification" is not generally defined, and therefore its meaning must be ascertained from this section.
(1) Previously in Oklahoma, as discussed under Section 2-401, a purchaser obtained "title" to the goods, or no interest at all, by virtue of a contract of sale. Therefore, the principle of conveying an "insurable interest" is new, but commercially sound.
(a) Previously in Oklahoma, title to existing goods in a deliverable state passed when the contract was made. See authorities cited at Section 2-401. Note that the Commercial Code makes no distinction between goods in a deliverable state, and those upon which the seller is obliged to perform work or labor. The official comment states that the buyer should obtain an insurable interest even though additional labor is to be performed.
(b) See comments above.
(c) Under the common law doctrine of "potential possession," a vendor could enter into a contract for the sale of future crops or the young of animals, and "title" would pass at the time the seed germinated or the young were conceived. Vold on Sales, 2d Ed., § 45. There have been no previous cases in Oklahoma, but the statutes allowed liens on future crops. 42 O.S. §§ 8, 42. The Commercial Code is consistent with the common law doctrine, except for the limitation in time.
(2) and (3) Although there are no previous Oklahoma cases this is consistent with the vendor's lien concept, in which the seller clearly has an insurable interest, or the insurable interest he may have as a bailee. The last sentence permits the seller to substitute other goods, which, of course, must be construed to mean "other conforming goods." This, too, is limited to cases in which the buyer has not selected particular goods, but has acquiesced in the seller's identification of goods
