Maine Revised Statutes

§2-606. What constitutes acceptance of goods

(1).    Acceptance of goods occurs when the buyer
(a). After a reasonable opportunity to inspect the goods signifies to the seller that the goods are conforming or that he will take or retain them in spite of their nonconformity; or
(b). Fails to make an effective rejection (section 2-602, subsection (1)), but such acceptance does not occur until the buyer has had a reasonable opportunity to inspect them; or
(c). Does any act inconsistent with the seller's ownership; but if such act is wrongful as against the seller it is an acceptance only if ratified by him.
(2).    Acceptance of a part of any commercial unit is acceptance of that entire unit.
