Okla. Stat. tit. 12A, § 12A-7-207: Goods must be kept separate - Fungible goods

Goods Must be Kept Separate; Fungible Goods.

(a) Unless the warehouse receipt otherwise provides, a

warehouse shall keep separate the goods covered by each receipt so

as to permit at all times identification and delivery of those

goods. However, different lots of fungible goods may be commingled.

(b) If different lots of fungible goods are commingled, the

goods are owned in common by the persons entitled thereto and the

warehouse is severally liable to each owner for that owner's share.

If, because of overissue, a mass of fungible goods is insufficient

to meet all the receipts which the warehouse has issued against it,

the persons entitled include all holders to which overissued

receipts have been duly negotiated.
