SANDERS, J.
¶1 Judith Young brought an action to quiet title against her nephew Jim Young and his wife, Shannon Young, over property located in Thurston County. Jim and Shannon counterclaimed for unjust enrichment based on improvements they made to the property. At issue is the measure of recovery in their unjust enrichment claim.
For clarity this opinion refers to the parties by first name.
¶2 The trial court awarded Jim and Shannon the market value of the improvements less certain costs the trial court determined did not apply. The Court of Appeals reversed, concluding the trial court should have used the full market value as the measure of recovery. We affirm the Court of Appeals.
I. FACTS
¶3 The facts are undisputed. Judith runs an otter sanctuary in rural Georgia. Jim is a licensed and bonded contractor engaged in timber cutting, clearing, grading, dozing, and concrete slab construction. Jim and Shannon reside in Washington with their four children.
¶4 Judith expressed to Jim and Shannon her desire to move her otter sanctuary away from Georgia. In 1998 Jim became familiar with a piece of property for sale in Thurston County; the land and the buildings were in significant disrepair but Jim and Shannon thought it had characteristics suitable to Judith's needs. Jim and Shannon told Judith about the property, including its run-down condition and potential for development. The three agreed Jim and Shannon would do all the work necessary to ready the property for Judith and her otters.
¶5 Judith purchased the Thurston County property in 1998 for $1,050,000. Judith included Jim's name on the title in the good-faith belief this would allow Jim to obtain the necessary permits and approvals for the improvements. As a result of conversations with Judith, Jim reasonably believed Judith would pay him for his improvements to the property.
¶6 That year Jim and Shannon moved onto the property with Judith's knowledge and lived there rent-free. Between the purchase of the property and the time of trial, Jim and Shannon did a large amount of work on the property. They extensively remodeled the house, demolished an older farmhouse, repaired a number of outbuildings, replaced the well equipment, cleared the property, and replaced the fencing, among other projects. All of the work was of workmanlike quality or better.
¶7 By the spring of 2001 Jim and Shannon began to suspect Judith would not move to the Thurston County property. They contacted her to discuss the possibility of turning the property into a working cattle ranch. By June 2001 all three believed in good faith they had formed an oral agreement to develop a cattle ranch. Jim and Shannon's understanding of the agreement differed significantly from Judith's understanding, but they began to develop the cattle ranch in good faith according to their respective understandings of the agreement. By the fall of 2002 the relationship had soured and the parties had stopped communicating with each other.
¶8 In April 2003 Judith brought an action to quiet title in her name and to eject Jim and Shannon from the property, among other claims. Jim and Shannon counterclaimed for unjust enrichment based on the work they performed on the property, among other claims. The trial court quieted title in Judith's name.
¶9 The court then determined it would be unjust for Judith to retain the value of the work on the Thurston County property without compensating Jim and Shannon for it. Expert testimony established the improvements would have cost Judith $760,382 if she had hired a third-party contractor to perform them. The court also found the value of the property increased by $1,150,000 to $1,450,000, but only $750,000 to $1,050,000 of the increased value was attributable to Jim and Shannon's improvements. Neither party contests these findings.
"[U]nchallenged findings of fact become verities on appeal." Davis v. Dep't of Labor Indus., 94 Wn.2d 119, 123, 615 P.2d 1279 (1980) (citing Goodman v. Bethel Sch. Dist. No. 403, 84 Wn.2d 120, 124, 524 P.2d 918 (1974)).
¶10 The court found the measure of recovery in an unjust enrichment claim is generally the greater of (1) the cost to the owner of obtaining the same services from a third party and (2) the amount the services have increased the value of the property. However, the court declined to apply this measure under the "particular circumstances of this case." Clerk's Papers (CP) at 639. Instead, it awarded Jim and Shannon the market value of the improvements, less the "general contractor's costs" listed in the cost expert's report. CP at 640. The total award was $501,866.
¶11 Jim and Shannon appealed. In an unpublished opinion, Division Two of the Court of Appeals reversed, holding the trial court incorrectly measured recovery. It remanded for an award based on the full amount it would have cost Judith to pay a third party to make the improvements. Young v. Young, noted at 134 Wn. App. 1033, 2006 WL 2329471, at *10-15, 2006 Wash. App. LEXIS 1768, at *15. We granted Judith's petition for review at 160 Wn.2d 1010 (2007) and affirm the Court of Appeals.
II. ANALYSIS A
¶12 Jim and Shannon argue the measure of recovery is either the market value of the services provided or the increase in value attributable to their work. Judith argues the circumstances of the claimant affect the measure of recovery. Our review is de novo because the only issue is the legal standard of recovery. See Crafts v. Pitts, 161 Wn.2d 16, 22, 162 P.3d 382 (2007); Fisher Props., Inc. v. Arden-Mayfair, Inc., 106 Wn.2d 826, 843, 726 P.2d 8 (1986).
B
¶13 Jim and Shannon characterize the measure of recovery as "unjust enrichment" whilst Judith characterizes the measure of recovery as "quantum meruit." As an initial matter we take this opportunity to conceptually clarify the distinction between "unjust enrichment" and "quantum meruit." Washington courts have historically used these terms synonymously, but the distinction between them is legally significant. Our purpose is to standardize the nomenclature and eliminate unnecessary multiplicity of terms.
Occam's Razor instructs " Entia non sunt multiplicanda praeter necessitatem," which translates into today's vernacular as "Keep it simple." Casarez v. Val Verde County, 16 F. Supp. 2d 727, 729 (W.D. Tex. 1998) (emphasis added).
¶14 The two terms are distinct approaches founded on discrete legal theories: contracts implied in law and contracts implied in fact. See Chandler v. Wash. Toll Bridge Auth., 17 Wn.2d 591, 600, 137 P.2d 97 (1943) ("[T]he law recognizes two classes of implied contracts: those implied in fact, and others implied in law."); see also Martin u. Campanaro, 156 F.2d 127, 130 n. 5 (2d Cir. 1946).
¶15 Unjust enrichment is the method of recovery for the value of the benefit retained absent any contractual relationship because notions of fairness and justice require it. See Bailie Commc'ns, Ltd. v. Trend Bus. Sys., Inc., 61 Wn. App. 151, 160, 810 P.2d 12 (1991) ("Unjust enrichment occurs when one retains money or benefits which in justice and equity belong to another.").
¶16 In such situations a quasi contract is said to exist between the parties. Bill v. Gattavara, 34 Wn.2d 645, 650, 209 P.2d 457 (1949) (stating, "the terms `restitution' and `unjust enrichment' are the modern designations for the older doctrine of `quasi contracts.'"); State v. Cont'l Baking Co., 72 Wn.2d 138, 143, 431 P.2d 993 (1967) ("`If the defendant be under an obligation, from the ties of natural justice, to refund; the law implies a debt, and gives this action, founded in the equity of the plaintiff's case, as it were upon a contract, ("quasi ex contractu",). . . .'") (internal quotation marks omitted) (quoting State ex rel. Employment Sec. Bd. v. Rucker, 211 Md. 153, 157-58, 126 A.2d 846 (1956)).
"Three elements must be established in order to sustain a claim based on unjust enrichment: a benefit conferred upon the defendant by the plaintiff; an appreciation or knowledge by the defendant of the benefit; and the acceptance or retention by the defendant of the benefit under such circumstances as to make it inequitable for the defendant to retain the benefit without the payment of its value."
Bailie Commc'ns, 61 Wn. App. at 159-60 (quoting BLACK'S LAW DICTIONARY 1535-36 (6th ed. 1990));
see also Lynch v. Deaconess Med. Ctr., 113 Wn.2d 162, 165, 776 P.2d 681 (1989) (stating elements as "the enrichment of the defendant must be unjust; and . . . the plaintiff cannot be a mere volunteer"). In other words the elements of a contract implied in law are: (1) the defendant receives a benefit, (2) the received benefit is at the plaintiff's expense, and (3) the
circumstances make it unjust for the defendant to retain the benefit without payment.
¶17 "Quantum meruit," on the other hand, is the method of recovering the reasonable value of services provided under a contract implied in fact. See, e.g., Eaton v. Engelcke Mfg., Inc., 37 Wn. App. 677, 681 P.2d 1312 (1984) (affirming quantum meruit award on basis of contract implied in fact); see also A.F.A.B., Inc. v. Town of Old Orchard Beach, 639 A.2d 103, 105 n. 3 (Me. 1994) (" Quantum meruit denotes recovery for the value of services or materials provided under an actual, implied-in-fact contract.").
"Quantum meruit" has also been used to recover the reasonable value of services provided when a change occurs that was not within the contemplation of the parties, and the change requires extra work and materials or causes a substantial loss to the claimant. Bignold v. King County, 65 Wn.2d 817, 826, 399 P.2d 611 (1965) (citing Schuehle v. City of Seattle, 199 Wash. 675, 92 P.2d 1109 (1939)). In addition "Quantum meruit" has been used to measure recovery for part performance. See Dravo Corp. v. L.W. Moses Co., 6 Wn. App. 74, 492 P.2d 1058 (1971). In each of these instances, however, some underlying contractual relationship between the parties affects the measure of recovery. See id. at 91-92. Hence the quantum meruit recovery falls under a contract implied in fact theory.
But see Heaton v. Imus, 93 Wn.2d 249, 253-54, 608 P.2d 631 (1980) (applying quantum meruit to contract implied in law); Losli v. Foster, 37 Wn.2d 220, 222 P.2d 824 (1950) (same). In Heaton and Losli the parties believed there was a binding contract. See Heaton, 93 Wn.2d at 251; Losli, 37 Wn.2d at 223. Nevertheless, in each case the court awarded recovery based on an implied in law contract, imprecisely using "quantum meruit" to describe the unjust enrichment remedy. Courts and litigants have applied the term "quantum meruit" to contracts implied in law and contracts implied in fact, institutionalizing ambiguity. See, e.g., Park v. Ross Edwards, Inc., 41 Wn. App. 833, 837-38, 706 P.2d 1097 (1985). Such proliferate application of legal terms is the "bane of the law" not easily eradicated. ConFold Pac, Inc. v. Polaris Indus., Inc., 433 F.3d 952, 957 (7th Cir. 2006).
¶18 A contract implied in fact
is an agreement depending for its existence on some act or conduct of the party sought to be charged and arising by implication from circumstances which, according to common understanding, show a mutual intention on the part of the parties to contract with each other. The services must be rendered under such circumstances as to indicate that the person rendering them expected to be paid therefor, and that the recipient expected, or should have expected, to pay for them.
Johnson v. Nasi, 50 Wn.2d 87, 91, 309 P.2d 380 (1957) (citing
Ross v. Raymer, 32 Wn.2d 128, 137, 201 P.2d 129 (1948)). In other words the elements of a contract implied in fact are: (1) the defendant requests work, (2) the plaintiff expects payment for the work, and (3) the defendant knows or should know the plaintiff expects payment for the work.
¶19 In sum, "unjust enrichment" is founded on notions of justice and equity whereas "quantum meruit" is founded in the law of contracts, a legally significant distinction. See Bailie Commc'ns, 61 Wn. App. at 160 ("Thus while quantum meruit, inasmuch as it involves retention of benefits in the form of services received, falls within the unjust enrichment doctrine, unjust enrichment applies to a far broader category of cases."); see also Candace S. Kovacic, A Proposal to Simplify Quantum Meruit Litigation, 35 AM. U. L. REV. 547, 553-62 (1986) (discussing the confusion surrounding these theories).
¶20 After reviewing the trial court's findings of fact and conclusions of law, we find it is unclear whether there was a contract implied in fact or a contract implied in law. Clearly Judith received a benefit at the plaintiff's expense and the circumstances make it unjust for her to retain that benefit without payment. Equally clear, however, is Judith's request for the work, Jim's reasonable expectation of payment for the work, and Judith's knowledge that Jim expected compensation.
¶21 Under a contract implied in fact, Jim and Shannon's recovery would be limited to the value of services rendered. See Bailie Commc'ns, 61 Wn. App. at 160; Eaton, 37 Wn. App. at 682. Nevertheless, Jim and Shannon do not to argue for an implied-in-fact contract. See Cahn v. Foster Marshall, Inc., 33 Wn. App. 838, 840, 658 P.2d 42 (1983) (stating, "[t]he burden of proving a contract, whether express or implied, is on the party asserting it. . . ."). Therefore, we must determine Judith's obligation under an implied-in-law contract and the equitable theory of unjust enrichment.
C
¶22 In the abstract the issue is whether the proper measure of recovery under unjust enrichment is the market value of the services rendered or the claimant's actual cost to render those services. In real terms the issue is whether the trial judge properly deducted $258,516 from the cost Judith would have paid a normal contractor to perform the work performed by Jim and Shannon, or whether Jim and Shannon are entitled to the full amount despite not incurring certain costs normally incurred in a business relationship.
$258,516 is the difference between the total market cost, $760,382, and the amount awarded by the trial judge, $501,866. Alternatively, the trial judge deducted $248,134 from the amount recoverable by Jim and Shannon, which is the difference between the lowest accretion in value attributable to Jim and Shannon's improvements, $750,000, and the amount awarded by the trial judge.
¶23 Washington law states the measure of recovery for unjust enrichment to a faultless claimant for the claimant's improvement to land is measured in one of two ways. It may be measured "by the amount which the benefit conferred would have cost the defendant had it obtained the benefit from some other person in the plaintiff's position." Noel v. Cole, 98 Wn.2d 375, 383, 655 P.2d 245 (1982) (citing RESTATEMENT (SECOND) OF CONTRACTS § 371, cmt. b (1981)), superseded by statute as stated in Dioxin/Organochlorine Ctr. v. Pollution Control Hearings Bd., 131 Wn.2d 345, 360, 932 P.2d 158 (1997). Alternatively, it may be measured by "the extent to which the other party's property has been increased in value or his other interests advanced." RESTATEMENT (SECOND) OF CONTRACTS § 371(b) (1981); see also Smith v. Favilla, 23 Wn. App. 59, 62-63, 593 P.2d 564 (1979).
¶24 Here, the value of the first measure is $760,382 while the value of the second measure is between $750,000 and $1,050,000. Therefore, under Washington law Jim and Shannon are entitled to an award between $750,000 and $1,050,000. Within this range the trial court, reviewing the complex factual matters involved in the case, has tremendous discretion to fashion a remedy "to do substantial justice to the parties and put an end to the litigation." Esmieu v. Hsieh, 92 Wn.2d 530, 535, 598 P.2d 1369 (1979); Hough v. Stockbridge, 150 Wn.2d 234, 76 P.3d 216 (2003). Yet here the trial court awarded $501,866, supposing the circumstances of the claimant affected the quantum of recovery. We find no support for this proposition.
¶25 Certainly, when a court calculates the recovery for unjust enrichment, not all cost is recoverable. As stated in the RESTATEMENT (SECOND) OF CONTRACTS, "a party's expenditures in preparation for performance that do not confer a benefit on the other party do not give rise to a restitution interest." RESTATEMENT (SECOND) OF CONTRACTS § 370 cmt. a (1981); see also id. § 371 cmt. b (stating, "expenditures are excluded to the extent that they conferred no benefit"). Here, however, the trial court deducted "mobilization/demobilization costs; the cost of providing supervision, tools and general equipment; the cost for debris disposal; a markup for overhead and profit; and construction contingency; the cost of bonds; insurance and business taxes; and the cost of Washington State sales tax." CP at 640. Undoubtedly some of these costs conferred a benefit to Judith.
¶26 Contrary to the dissent's assertion, the benefits derived from some of these costs are independent of the formality of the relationship. See dissent at 494-95. For example, Judith benefited by having Jim and Shannon dispose of the debris generated by the improvements she requested. Moreover, Judith benefited by having Jim and Shannon provide tools and equipment. In short, justice requires Judith to pay for the benefit she received from these services. The trial court erred in totally deducting all of these costs without an examination of whether these costs had some consequential relationship to the value of the benefit conferred. See A.F.A.B., Inc., 639 A.2d at 106 ("Such a blanket exclusion of a plaintiff's overhead, costs, and profits is improper unless the court determines that they have no meaningful relationship to the value of the benefit conferred and the extent to which a defendant has been enriched.").
"`If the defendant be under an obligation, from the ties of natural justice, to refund; the law implies a debt, and gives this action, founded in the equity of the plaintiff's case, as it were upon a contract, ("quasi ex contractu",). . . .'" Cont'l Baking Co., 72 Wn.2d at 143 (internal quotation marks omitted) (quoting Rucker, 211 Md. at 157-58).
The dissent conflates cost with value, often correlated but not intertwined terms. Dissent at 493. Cost refers to whatever is given to secure the benefit received, whereas value refers to the relative worth of the benefit to the recipient.
¶27 This approach does not bind the hand of the trial court as the dissent suggests. Dissent at 495. To the contrary, we recognize the complexity of informal construction arrangements and demand a careful analysis of the benefits conferred. This approach ensures the defendant remunerates the faultless claimant for every benefit conferred independent of the formality of the relationship.

¶28 Judith argues the court should not be constrained when calculating the unjust enrichment award based on improvements to real property. Instead, Judith argues, the trial court should have broad discretion to fashion a remedy based on the unique facts and circumstances of the parties. Judith's argument overlooks the focus of an unjust enrichment calculation.
¶29 The obligation to repay the debt or disgorge the value of the received benefit focuses on the receiver of the benefit, not on the provider of the benefit. See RESTATEMENT OF RESTITUTION: QUASI CONTRACTS AND CONSTRUCTIVE TRUSTS § 155(1) (1937) (stating, "the measure of recovery for the benefit thus received is the value of what was received").
[W]here money is awarded to protect a claimant's restitution interest, it may, depending on what "justice requires," be measured either by the reasonable value of what the other party has received,
as viewed through the eyes of the recipient, by looking to what the recipient would have had to pay
someone in the claimant's position to obtain the goods or services, or by the extent to which the other party's property has been increased in value. . . .
26 SAMUEL WILLISTON RICHARD A. LORD, A TREATISE ON THE LAW OF CONTRACTS § 68:35, at 424 (4th ed. 2003) (emphasis added).
¶30 Judith understands the phrase "in the claimant's position" to mean the court considers the claimant's circumstances when calculating his recovery. The claimant's position, however, refers to similar providers of like services, not the actual claimant; otherwise, the quantum of recovery would always be limited by the claimant's actual cost. Unjust enrichment recovery is limited only by the claimant's actual cost when the claimant is at fault. See Noel, 98 Wn.2d at 383 n. 6 (citing Edwards v. City of Renton, 67 Wn.2d 598, 607, 409 P.2d 153 (1965)). Here, neither Jim nor Shannon was at fault, so they are entitled to full restitution of Judith's unjust enrichment. Phrased alternatively, Judith must disgorge the entire value of the benefit she received as determined by either the fair market value of the services rendered or the amount the improvements enhanced the value of the property.
¶31 Notably, Judith requested the work. Under circumstances where a person asks for and receives valuable improvements to property, the person is required to pay the market value of what was received. See RESTATEMENT OF RESTITUTION, supra, § 155, cmt. d (1937) (stating, "the fact that [she] asked for them shows that they are of value to [her] and normally [she] would be required to pay the market price of such services. . . .").
¶32 Judith's theory of recovery is based on preventing a supposedly unconscionable gain to the claimant. Yet, her theory of recovery permits a defendant to retain some benefit. Under circumstances where the claimant is at fault and/or the defendant did not consent to the benefit, such a theory of recovery may be sound. See Edwards, 67 Wn.2d at 607 (limiting the recovery to cost because of violation to bidding statute). But where the claimant is not at fault and the defendant agreed to the improvements, fairness and justice dictate the defendant should be held to pay the entire amount as measured by how much it would have cost the defendant to purchase the improvements or by how much the improvement enhanced the value of the property. See Noel, 98 Wn.2d at 383; see also RESTATEMENT OF RESTITUTION, supra, § 158, cmt. d (1937) (stating, "where it is clear that the owner did desire improvements, it is fair that [she] should pay for them").
In fact, the property increased in value by at least $750,000 on account of Jim and Shannon's improvements. Limiting recovery to $501,866 allows Judith to retain a windfall of at least $248,134.
III. CONCLUSION
¶33 We affirm the Court of Appeals. We hold when calculating an unjust enrichment award in a quasi-contract action for improvements to real property, the award may not be reduced by the claimant's actual cost absent fault by the claimant or inconsequential relationship to the benefit conferred to the defendant. We remand to the trial court for recalculation of Jim and Shannon's award.
