The plaintiff, a lumber supplier, undertook by a contract dated July 2, 1986, to furnish (when and if ordered) building materials at stated prices and in stated quantities to the defendant Nordberg-Kelley Corporation, which was constructing a house for the defendant Lore. On August 29, the plaintiff filed notice of the contract in the registry of deeds to establish a mechanic’s lien on the house. See G. L. c. 254, § 4. The contract completion date was specified in the notice to be February 25, 1987, which was the date specified in the materials contract. See Hammill-McCormick Associates, Inc. v. New England Tel. & Tel. Co., 399 Mass. 541, 545 *365(1987). Prior to that date, on December 5, 1986, the plaintiff, pursuant to G. L. c. 254, § 8, recorded a statement of account showing $19,466.12 as the amount due on the contract. On February 18, 1987, still before the stated completion date, the plaintiff filed a second statement of account in the same amount and for the same supplies as the first. On that date it also filed a complaint asserting the existence of the lien and seeking its enforcement by sale of the house.
The complaint should have been dismissed as to the defendant Lore. General Laws c. 254, § 11, as amended by St. 1973, c. 1114, § 319, provides that “[t]he lien shall be dissolved unless a civil action to enforce it is commenced within sixty days after the filing of the statement required by section eight [i.e., the statement of account].” The lien referred to is created by the filing of the notice of contract under § 4. The lien may be lost either (1) under § 8, by a failure to file a statement of account within thirty days after the contract completion date, or (2) under § 11, by a failure to commence the enforcement action within sixty days after the filing of the statement of account. Cf. Burrell v. Way, 176 Mass. 164, 166-167 (1900).
The parties are in disagreement whether a statement of account filed prior to the specified contract completion date is, legally, a nullity, to be disregarded in applying the lien-dissolving provisions of § 8 and § 11. Without suggesting that such a statement of account is a nullity, we think the point is immaterial to the decision in this case. If the statement of account filed on December 5 was not a nullity, the lien was dissolved sixty days later because the enforcement action had not been commenced. There would then be no lien to which the statement of account filed on February 18 could attach. Compare Mulloy v. Lawrence, 31 Mo. 583, 585 (1862).2 See also Hilliard v. *366 Allen, 4 Cush. 532, 535-536 (1849). If, on the other hand, any statement of account filed prior to the completion date is a nullity, the action must still fail for failure of the plaintiff to show that it filed a statement of account during the thirty-day period following the completion date. In either case the plaintiff has failed to prove that it has a lien that may be enforced in this action.
The judgment entered under Mass.R.Civ.P. 54(b), 365 Mass. 821 (1974), against the defendant Lore is reversed, and a new judgment is to be entered dismissing the action as to him.
So ordered.
