[¶ 1] Associated Builders, Inc. appeals from a grant of a summary judgment entered in the Superior Court (Hancock County, Marsano, J.) in favor of the defendants William M. Coggins and Benjamin W. Coggins, d/b/a Ben & Bill’s Chocolate Emporium. Associated contends that the court erred when it held that despite a late payment by the Cogginses, an accord and satisfaction relieved the Cogginses of a contractual liability. The Cogginses argue that the three-day delay in payment was not a material breach of the accord and, even if the breach was material, Associated waived its right to enforce the forfeiture. We agree with the Cogginses and affirm the judgment.
[¶ 2] Associated provided labor and materials to the Cogginses to complete a structure on Main Street in Bar Harbor. After a dispute arose regarding compensation, Associated and the Cogginses executed an agreement stating that there existed an outstanding balance of $70,005.54 and setting forth the following terms of repayment:
It is agreed that, two payments will be made by [the Cogginses] to [Associated] as follows: Twenty Five Thousand Dollars ($25,000.00) on or before June 1, 1996 and Twenty Five Thousand Dollars ($25,000.00) on or before June 1,1997. No interest will be charged or paid providing payments are made as agreed. If the payments are not made as agreed then interest shall accrue at 10% [ ] per annum figured from the date of default. There will be no prepayment penalties applied. It is further agreed that Associated Builders will forfeit the balance of Twenty Thousand and Five Dollars and Fifty Four Cents ($20,005.54) providing the above payments are made as agreed.
The Cogginses made their first payment in accordance with the agreement. The second payment, however, was delivered three days late on June 4, 1997. Claiming a breach of the contract, Associated filed a complaint demanding the balance of $20,005.54, plus interest and cost. The Cogginses answered the complaint raising the affirmative defense of an accord and satisfaction and waiver. Both parties moved for a summary judg *1280 ment. The court granted the Cogginses’ motion and Associated appealed.
[¶3] The trial court must enter a summary judgment “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, referred to in the statements required by [M.R. Civ. P.] 7(d) show that there is no genuine issue as to any material fact set forth in those statements and that any party is entitled to a judgment as a matter of law.” M .R. Civ. P. 56(c). “On appeal from a grant of summary judgment, we view the evidence in the light most favorable to the nonprevail-ing party, and review the trial court decision for errors of law.”
Greenvall v. Maine Mutual Fire Ins. Co.,
[¶ 4] “An accord ‘is a contract under which an obligee promises to accept a substituted performance in future satisfaction of the obligor’s duty.’”
E.S. Herrick Co. v. Maine Wild Blueberry Co.,
[¶ 5] Satisfaction is the execution or performance of the accord.
See
Restatement (Second) of Contracts § 281(1) (1981). If the obligor breaches the accord, the obligee may enforce either the original duty or any duty pursuant to the accord.
See id.
§ 281(2) (1981);
see also
Arthur L. Corbin, 6 Corbin on Contracts § 1271, at 93-94 (1961). The obligor’s breach of the accord, however, must be material.
See Zenith Drilling Corp. v. Internorth, Inc.,
[¶ 6] We apply traditional contract principles to determine if a party has committed a material breach.
See Down East Energy Corp. v. RMR, Inc.,
[¶ 7] We discern no error in the Superior Court’s finding that the Cogginses’ payment to Associated after a three-day delay was not
*1281
a material breach and, therefore, satisfied the June 15, 1995 accord.
See A.E. Giroux, Inc.,
[¶ 8] Even if the breach was material and Associated could have enforced the forfeiture, Associated waived that right when it accepted the late payment. A waiver is a voluntary or intentional relinquishment of a known right.
See Kirkham v. Hansen,
[¶ 9] The trial court, therefore, did not err when it held that a satisfaction of the accord occurred when Associated accepted the final payment.
The entry is:
Judgment affirmed.
Notes
. The Restatement lists five factors as significant in determining if a failure to render performance is material:
(a) the extent to which the injured party will be deprived of the benefit which he reasonably expected;
(b) the extent to which the injured party can be adequately compensated for the part of that benefit of which he will be deprived;
(c) the extent to which the party failing to perform ... will suffer forfeiture;
(d) the likelihood that the party failing to perform ... will cure his failure ...;
(e) the extent to which the behavior of the party failing to perform or to offer to perform comports with standards of good faith and fair dealing.
Restatement (Second) of Contracts § 241 (1981).
