Mass. Gen. Laws ch. 106, § 7-104: Negotiable and Nonnegotiable Document of Title

Section 7–104. (a) Except as otherwise provided in subsection (c), a document of title is negotiable if by its terms the goods are to be delivered to bearer or to the order of a named person.

(b) A document of title, other than such a document described in subsection (a), is nonnegotiable. A bill of lading that states that the goods are consigned to a named person is not made negotiable by a provision that the goods are to be delivered only against an order in a record signed by the same or another named person.

(c) A document of title is nonnegotiable if, at the time it is issued, the document has a conspicuous legend, however expressed, that it is nonnegotiable.
