This is an action of contract brought by the trustee in bankruptcy of Zef Parabicoli & Sons, Inc. (the contractor) against S. Lawrence- Schlager, Judith R. Schlager, Alba A. Jameson and Arlene T. Vecchi (the owners) for money owed under a written construction contract. In May, 1963, the contractor agreed with the owners to build a post office on their property in Wellesley for a price later amended to $109,000. By the amendment the work was to be substantially completed by July 1, 1964, and time was to be of the essence. In accordance with the contract, the contractor provided performance and payment bonds, and in its application for the bonds assigned to the surety, Maryland Casualty Company, all payments due or to become due under the contract. No financing statement with respect to the assignment was filed under the Uniform Commercial Code, G. L. c. 106, §§ 9-101 et seq. The surety appears to be the real defendant in this action, under an agreement to indemnify the owners.
Work began in January, 1964, and by June 26, 1964, the owners had paid the contractor $66,650. On June 26, 1964, an involuntary petition in bankruptcy was filed against the contractor, but by order of the referee in bankruptcy the contractor continued to operate under the supervision of a receiver. On August 1, 1964, the Post Office Department accepted the building and began to pay rent under a lease from the owners. On October 27, 1964, the contractor was adjudicated a bankrupt and the plaintiff, who had been, the receiver, was appointed trustee.
The owners refused to pay a requisition in the amount of $27,990 submitted by the contractor on July 1, 1964, for work completed up to that date. On July 21, there was a conference of representatives of the Post Office' Department, the surety, the contractor, its receiver and the owners; the attorney for the surety, at the request of the owners and with the approval of the contractor, agreed that the surety would assume responsibility for completion. Late in September, the contractor submitted a final requisition in the amount of $42,850, which the owners refused to pay. In *791 October, 1964, the surety paid more than $60,000 to subcontractors who had furnished labor and materials for the building. On August 30, 1965, the owners paid the balance of the contract price, less more than $5,000 in disputed “back charges,” to the surety in the net amount of $36,630.11. The owners now contend that payment to the surety discharged any obligation to the plaintiff.
The judge, sitting without a jury, held that the surety’s claim to the contract balance was not subject to the Uniform Commercial Code and found for the owners. We agree.
1. If the surety were claiming the balance due under the contract by virtue of the assignment to it in the contractor’s bond application, it would be fairly arguable that it was claiming a “security interest” in a “contract right.” G. L. c. 106, §§ 1-201 (37), 9-102, 9-106. If there were such a security interest, it would be subordinate to the rights of a person who became a lien creditor without knowledge of the security interest and before it was perfected, and a trustee in bankruptcy would ordinarily have the rights of such a lien creditor. G. L. c. 106, §§ 9-301 (1) (b), 9-301 (3). Bankruptcy Act, § 70c, 11 U. S. C. § 110 (c) (1964). To perfect a security interest, a financing statement must be filed unless the case is within one of several exceptions. G. L. c. 106, § 9-302 (1). We do not pass on the question whether the assignment to the surety in this case was excepted as “a transfer of a contract right to an assignee who is also to do the performance under the contract,” G. L. c. 106, § 9-104 (f), or “an assignment of accounts or contract rights which does not alone or in conjunction with other assignments to the same assignee transfer a significant part of the outstanding accounts or contract rights of the assignor . . ..” G. L. c, 106, § 9-302 (1) (e). Bee Gilmore, Security Interests in Personal Property, §§ 10.5, 19.6. •
2. The surety makes an alternative claim, not resting on the assignment to it by the contractor, that it is subrogated to the rights of the contractor to the contract balance, to the rights of the owners, and to the rights of the subcontractors it paid. Such claims are not superseded by the
*792
Uniform Commercial Code. Section 1-103 of the Code provides in part, “Unless displaced by the particular provisions of this chapter, the principles of law and equity . . . shall supplement its provisions.” “No provision of the Code purports to affect the fundamental equitable doctrine of subrogation.”

v.
Commercial Realty & Fin. Co. Inc.
Our conclusion that filing under the Code is unnecessary to preserve the priority of a surety’s right of subrogation over the rights of a construction contractor’s trustee in bankruptcy is reinforced by decisions of other courts.

3. The plaintiff here argues that we should “establish a degree of certainty (indeed, even a degree of sanity) to the determination of priorities among claimants to construction contract proceeds” by enunciating “an absolute requirement that sureties engaged in bonding construction projects perfect security interests in their assignment by filing.” See Notes, 4 B. C. Ind. & Commercial L. Rev. 748, 755; 65 Col. L. Rev. 927, 933. We find that the draftsmen and sponsors of the Uniform Commercial Code did not overlook the problems of construction contract sureties. The 1952 Official Draft included § 9-312 (7), subordinating the surety’s interest to a later interest taken by a party who gave new value to enable the debtor to perform his obligation; that provision was deleted in 1953, with an explanation by the editorial board that representatives of the surety companies had complained that it changed settled law and that the problem should be left to agreements for subordination.

4. The plaintiff argues that, even if “the anachronistic doctrine of equitable subrogation still has vitality,” the surety has only the rights of those to whose rights it would be subrogated, and that they had none. Under

An argument is made, based on
Ehrlich
v.
Johnson Serv. Co.
The plaintiff is not helped by Bankruptcy Act § 70c, 11 U. S. C. § 110 (c) (1964), giving him the rights of a judgment creditor of the bankrupt with a hen by legal proceedings. Such rights date from June 26, 1964, when the petition in bankruptcy was filed; the surety’s right dates back

to the date of its bond.

Harvard Trust Co.
5. The plaintiff complains that the surety improperly yielded to the owners’ claims of more than $5,000 of “back charges.” The surety paid more than $60,000 of debts owed by the contractor, and was reimbursed $36,630.11. In these circumstances, if $5,000 more was owred, it should have been paid to the surety rather than to the plaintiff.
There was no error.
Exceptions overruled.
Notes
“The Surety Companies' representatives convincingly took the position that subsection (7) as it stands is a complete reversal of the case law not only of the Supreme Court of the United States but also of the highest courts of most of the states. They cited

v.
United States,
“The typical case involved is a case in which a surety company, as a prerequisite to the execution of a performance bond, requires a contractor to make an assignment of all moneys coming to the contractor from the owner. Later, the contractor goes to a bank and obtains a loan presumably or actually for the purpose of enabling him to perform his contract.
“Under the cited case law, the surety's rights come_ first as to the funds owing by the owner unless the surety has subordinated its right to the bank. Subsection (7) of the Code as written would reverse the situation and give the bank priority in all pases,
