Okla. Stat. tit. 12A, § 12A-7-307: Lien of carrier

Lien of Carrier.

(a) A carrier has a lien on the goods covered by a bill of

lading or on the proceeds thereof in its possession for charges

subsequent to the date of the carrier’s receipt of the goods for

storage or transportation, including demurrage and terminal charges,

and for expenses necessary for preservation of the goods incident to

their transportation or reasonably incurred in their sale pursuant

to law. However, against a purchaser for value of a negotiable bill

of lading, a carrier's lien is limited to charges stated in the bill

or the applicable tariffs or, if no charges are stated, a reasonable

charge.

(b) A lien for charges and expenses under subsection (a) of

this section on goods that the carrier was required by law to

receive for transportation is effective against the consignor or any

person entitled to the goods unless the carrier had notice that the

consignor lacked authority to subject the goods to those charges and

expenses. Any other lien under subsection (a) of this section is

effective against the consignor and any person that permitted the

bailor to have control or possession of the goods unless the carrier

had notice that the bailor lacked authority.

(c) A carrier loses its lien on any goods that it voluntarily

delivers or unjustifiably refuses to deliver.
