ZARELLA, J.
The defendants, Bettina Snyder, Donald Snyder and CS Industries, LLC (CS Industries),1 appeal from the judgment of the trial court2 awarding damages to the plaintiffs, Patricia Smith,3 Carol Tartagni and Lectron Labs, Inc. (Lectron). The defendants claim that there was insufficient evidence to support the trial court’s award of damages. The defendants alternatively claim that, even if the evidence supported the award of damages, the trial court improperly determined the amount of damages and attorney’s fees. We conclude that the trial court properly determined that Lectron was entitled to damages and affirm the trial court’s award of attorney’s fees.
The following facts and procedural history are relevant to this appeal. In October, 1999, the plaintiffs brought an action against the defendants alleging, inter alia, that the named defendant, Charles Snyder,4 while serving as a director and officer of Lectron, breached a fiduciary duty that he owed to Lectron by engaging [459]*459in a pattern of self-dealing and other abuses of his position that were designed to destroy or devalue Lectron. The plaintiffs further alleged that certain other defendants conspired with Charles Snyder in his alleged improprieties. Among other things, the plaintiffs claimed that the defendants misappropriated corporate property and that their conduct violated the Connecticut Unfair Trade Practices Act (CUTPA), General Statutes § 42-110a et seq.
Thereafter, the plaintiffs moved for a default judgment on the basis of the defendants’ repeated failure to comply with discovery orders. The trial court granted the plaintiffs’ motion and rendered judgment in their favor on the issue of liability. Subsequently, the trial court held a hearing on damages at which three witnesses testified. Vincent Sorrentino, Smith’s agent and husband, testified on behalf of the plaintiffs. David Veilleux, a certified public accountant, testified on behalf of the plaintiffs with respect to the common stock value of Lectron as of December, 1998. And Bettina Snyder, a former employee of Lectron and current employee of CS Industries, testified on behalf of the defendants.
The trial court set forth the following findings of fact in its memorandum of decision. “The plaintiffs protected their suppliers, customers, pricing schemes and processes, and treated them as proprietary information. The defendants kept [a] competing venture secret from the plaintiffs. Specifically, the defendants, while in the plaintiffs’ employ: (1) started a competing business, (2) utilized fraudulent means to misappropriate the plaintiffs’ most productive and efficient machine, (3) [discouraged] the plaintiffs’ existing customers by over-quoting jobs, (4) disrupted the plaintiffs’ cash flow by not sending out bills, (5) altered the plaintiffs’ company records to prevent the plaintiffs from being able to rehire employees who had been laid off, and (6) solic[460]*460ited the plaintiffs’ customers and diverted them to the defendants’ new business venture.”
The trial court concluded that the plaintiffs were entitled to damages under common law, the Uniform Trade Secrets Act, General Statutes § 35-50 et seq., and CUTPA. The trial court awarded the plaintiffs the following: (1) $235,000 in compensatory damages on the basis of the defendants’ violation of the common law, CUTPA and the Uniform Trade Secrets Act; (2) $40,000 in punitive damages under the Uniform Trade Secrets Act; (3) $40,000 in punitive damages under CUTPA; and (4) $20,000 in attorney’s fees.
I
Prior to addressing the defendants’ claims on appeal, we address the issue of whether the individual shareholder plaintiffs, Smith and Tartagni, have standing.5 “The issue of standing implicates this court’s subject matter jurisdiction. . . . Standing is the legal right to set judicial machinery in motion. One cannot rightfully invoke the jurisdiction of the court unless he [or she] has, in an individual or representative capacity, some real interest in the cause of action, or a legal or equitable right, title or interest in the subject matter of the controversy. . . . When standing is put in issue, the question is whether the person whose standing is challenged is a proper party to request an adjudication of the issue .... Standing requires no more than a colorable claim of injury; a [party] ordinarily establishes . . . standing by allegations of injury. Similarly, standing exists to attempt to vindicate arguably protected interests. . . .
“Standing is established by showing that the party claiming it is authorized by statute to bring suit or is classically aggrieved. . . . The fundamental test for [461]*461determining aggrievement encompasses a well-settled twofold determination: first, the party claiming aggrievement must successfully demonstrate a specific, personal and legal interest in [the subject matter of the challenged action], as distinguished from a general interest, such as is the concern of all members of the community as a whole. Second, the party claiming aggrievement must successfully establish that this specific personal and legal interest has been specially and injuriously affected by the [challenged action], . . . Aggrievement is established if there is a possibility, as distinguished from a certainty, that some legally protected interest . . . has been adversely affected.” (Citations omitted; internal quotation marks omitted.) AvalonBay Communities, Inc. v. Orange, 256 Conn. 557, 567-68, 775 A.2d 284 (2001).
“Since at least the middle of the [nineteenth] century, it has been accepted in this country that the law should permit shareholders to sue derivatively on their corporation’s behalf under appropriate conditions. . . . [I]t is axiomatic that a claim of injury, the basis of which is a wrong to the coiporation, must be brought in a derivative suit, with the plaintiff proceeding secondarily, deriving his rights from the corporation which is alleged to have been wronged.” (Citation omitted; internal quotation marks omitted.) Fink v. Golenbock, 238 Conn. 183, 200, 680 A.2d 1243 (1996).
“[I]n order for a shareholder to bring a direct or personal action against the corporation or other shareholders, that shareholder must show an injury that is separate and distinct from that suffered by any other shareholder or by the corporation.” Id., 201. It is commonly understood that “[a] shareholder—even the sole shareholder—does not have standing to assert claims alleging wrongs to the corporation.” Jones v. Niagara, Frontier Transportation Authority, 836 F.2d 731, 736 [462]*462(2d Cir. 1987), cert. denied, 488 U.S. 825, 109 S. Ct. 74, 102 L. Ed. 2d 50 (1988).
We conclude, therefore, that Smith and Tartagni lacked standing to bring this action in their individual capacities because the allegations in the plaintiffs’ complaint, if true, demonstrate that Lectron was harmed, but that no specific shareholder sustained an injury separate and distinct from that suffered by any other shareholder or by the corporation. Accordingly, the individual claims of Smith and Tartagni must be dismissed.
II
The defendants’ first claim on appeal involves the trial court’s determination that the plaintiffs were entitled to compensatory damages. The trial court’s award of compensatory damages was based on its conclusion that the defendants had violated the common-law theory of misappropriation of trade secrets, which is codified in Connecticut’s Uniform Trade Secrets Act, the common-law theory of misappropriation of property, and CUTPA.6 As a threshold matter, we note that a trial court’s findings of fact will be reversed only if they are clearly erroneous. E.g., Tarullo v. Inland Wetlands & Watercourses Commission, 263 Conn. 572, 581, 821 A.2d 734 (2003).
The defendants claim that, to the extent that the trial court’s award of damages was based on its conclusion that the defendants had violated the Uniform Trade Secrets Act, it was improper because there was insuffi[463]*463cient evidence to establish that Lectron possessed protected information about customers, pricing schemes and processes and treated it as proprietary information.7 Thus, the defendants contend that the information at issue did not constitute trade secrets. We disagree.
General Statutes § 35-51 (d) defines a trade secret as “information, including a formula, pattern, compilation, program, device, method, technique, process, drawing, cost data or customer list that: (1) Derives independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use, and (2) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.” (Emphasis added.)
The trial court found that Lectron protected information about its suppliers, customers, pricing schemes and processes, and treated it as proprietary information. The court concluded that the defendants improperly had appropriated this information. Our review of the transcript from the damages hearing reveals that there was sufficient evidence to support the trial court’s factual findings. At the damages hearing, for example, Sorrentino specifically was asked, “[D]id you keep your customers—who your customers were and your pricing scheme, and things of that nature—did Lectron . . . treat that information as confidential?” Sorrentino responded, “Yes, we did.” Sorrentino also testified that Bettina Snyder and Donald Snyder, among others, were aware that such information was confidential. Thus, [464]*464there was sufficient evidence to permit the trial court to award damages under the Uniform Trade Secrets Act.
The defendants claim, however, that there was no evidence to support a finding that the defendants actually misappropriated trade secrets or nontrade secret property. We disagree. General Statutes § 35-51 (b) defines misappropriation as: “(1) Acquisition of a trade secret of another by a person who knows or has reason to know that the trade secret was acquired by improper means; or (2) disclosure or use of a trade secret of another without express or implied consent by a person who (A) used improper means to acquire knowledge of the trade secret; or (B) at the time of disclosure or use, knew or had reason to know that his knowledge of the trade secret was (i) derived from or through a person who had utilized improper means to acquire it; (ii) acquired under circumstances giving rise to a duty to maintain its secrecy or limit its use, including but not limited to disclosures made under section 1-210, sections 31-40j to 31-40p, inclusive, or subsection (c) of section 12-62; or (iii) derived from or through a person who owed a duty to the person seeking relief to maintain its secrecy or limit its use; or (C) before a material change of his position, knew or had reason to know that it was a trade secret and that knowledge of it had been acquired by accident or mistake.”
The trial court’s determination that the defendants misappropriated trade secrets was based on its finding that the defendants had “solicited [Lectron’s] customers and diverted them to the defendants’ new business venture [namely, CS Industries].” First, the allegations of the plaintiffs’ complaint support the trial court’s factual determination, and it is well settled that “[t]he entry of a default constitutes an admission by the defendant of the truth of the facts alleged in the complaint.” DeBlasio v. Aetna Life & Casualty Co., 186 Conn. 398, 400, 441 A.2d 838 (1982). The plaintiffs alleged in their com[465]*465plaint, for example, that the defendants usurped Lectron’s customers. Second, a review of the transcript from the hearing in damages further demonstrates that there was sufficient evidence to support the trial court’s factual findings. There was testimony that the defendants had solicited Lectron’s customers and diverted them to the defendants’ new business venture.
The trial court also determined that the defendants had violated the common-law theory of misappropriation of nontrade secret property by using fraudulent means to misappropriate Lectron’s most productive and efficient machine. Similarly, the trial court’s determination. is supported by the pleadings and by evidence adduced at the hearing in damages. The plaintiffs alleged in their complaint that several of the defendants arranged to remove an electron beam welder from the premises of Lectron so that it could be reinstalled at the premises of CS Industries. There was also testimony at the damages hearing that the defendants started a competing business, namely, CS Industries, and utilized fraudulent means to misappropriate the plaintiffs’ most productive and efficient machine.
The allegations contained in the plaintiffs’ complaint, which are deemed to be established conclusively, and the evidence adduced at the damages hearing, therefore, demonstrate that there was ample support for the trial court’s determination that Lectron was entitled to damages under the common law and the Uniform Trade Secrets Act.8
Ill
The defendants also claim on appeal that, even if the trial court properly determined that the plaintiffs were entitled to damages, the amount of compensatory dam[466]*466ages, punitive damages and attorney’s fees that the trial court actually awarded was improper. We first note that a trial court is vested with “broad discretion in determining whether damages are appropriate. ... Its decision will not be disturbed . . . absent a clear abuse of discretion.” (Citation omitted; internal quotation marks omitted.) Elm City Cheese Co. v. Federico, 251 Conn. 59, 90, 752 A.2d 1037 (1999).
A
First, the defendants claim that the trial court’s award of compensatory damages was improper. The defendants claim that the trial court improperly calculated compensatory damages because it: (1) failed to consider that the individual shareholder plaintiffs did not have a 100 percent interest in Lectron, a fact that should have served to reduce the compensatory damages award; and (2) failed to deduct the proper amount of the proceeds from the sale of various pieces of Lectron’s equipment.
On the basis of our earlier conclusion that the individual shareholder plaintiffs lack standing in the present matter; see part I of this opinion; we need not address the first part of the defendants’ claim. This issue is moot in light of our decision to direct the trial court to render judgment dismissing the action as to Smith and Tartagni.
In support of the second part of their claim regarding compensatory damages, the defendants assert that the trial court improperly reduced the compensatory damages award by $15,000 instead of $127,000 to reflect the proceeds of the sale of Lectron’s equipment. The defendants contend that the trial court failed to consider evidence adduced at the damages hearing that Lectron received $127,000 for the sale of the equipment.
Although the defendants correctly note that Sorrentino testified at the damages hearing regarding the pro[467]*467ceeds from the sale of Lectron’s equipment, Sorrentino’s testimony was vague at best. For example, when Sorrentino was questioned about the sale proceeds, he was unable to recall how much money Lectron had received with any degree of precision or certainty. Moreover, our review of the record reveals no supporting documentation regarding the sale proceeds. It was within the trial court’s discretion, therefore, to weigh Sorrentino’s testimony and to decide whether to rely on it in its calculation of compensatory damages. See Bieluch v. Bieluch, 199 Conn. 550, 555-56, 509 A.2d 8 (1986).
Moreover, because the defendants elected not to file a motion for articulation to illuminate further the basis for the compensatory damages award, this court can only speculate as to how and why the trial court arrived at that sum. We repeatedly have stated that it is the appellant’s responsibility to provide an adequate record for review. E.g., Walton v. New Hartford, 223 Conn. 155, 164-65, 612 A.2d 1153 (1992). Thus, in light of the discretion afforded the trial court in determining the amount of damages to be awarded and in crediting or discrediting the testimony of witnesses, we conclude that the trial court’s award of compensatory damages was proper. See Bieluch v. Bieluch, supra, 199 Conn. 555-56.
B
The defendants next contend that the trial court improperly awarded punitive damages under CUTPA because an award of such damages under CUTPA requires evidence that the defendants demonstrated a reckless indifference to the rights of the plaintiffs. In the present case, the trial court’s finding of reckless indifference was premised on the defendants’ breach [468]*468of fiduciary duties.9 The defendants claim that the only defendant that was alleged to have breached a fiduciary duty was Charles Snyder, who is no longer a party to this action. Thus, the defendants claim that the trial court improperly awarded punitive damages under CUTPA against the remaining defendants in this action because there was no direct or circumstantial evidence to establish that they demonstrated a reckless indifference to the plaintiffs’ rights. We disagree.
We have stated that when “two or more persons unite in an act which constitutes a wrong to another, intending at the time to commit it, or in doing it under circumstances which fairly charge them with intending the consequences which follow, they incur a joint and several liability for the acts of each and all of the joint participants. . . . Whe[n] . . . the evidence supports the conclusion that there was concerted action, each participant is . . . liable for the entire injury caused by the concerted action.” (Citation omitted; internal quotation marks omitted.) Lamb v. Peck, 183 Conn. 470, 472-73, 441 A.2d 14 (1981).
In their complaint, the plaintiffs alleged that Charles Snyder breached his fiduciary duties to Lectron as an officer and director. The plaintiffs further alleged in their complaint that the remaining defendants conspired with Charles Snyder in the breach of his fiduciary duties. As we have discussed previously in this opinion, the entry of the default judgment conclusively established the facts alleged in the plaintiffs’ complaint. Our decision in Lamb and the allegations in the plaintiffs’ complaint, therefore, inform our conclusion that the remaining defendants in the present case are jointly and severally liable for Charles Snyder’s breach of his [469]*469fiduciary duties. We conclude, therefore, that the trial court did not abuse its discretion in awarding $40,000 in punitive damages under CUTPA.
C
The defendants next claim that the trial court improperly awarded $40,000 in punitive damages under the common law because the plaintiffs had failed to plead punitive damages, which the defendants contend is required under Connecticut law. See Associated Investment Co. Ltd. Partnership v. Williams Associates IV, 230 Conn. 148,161 n.16, 645 A.2d 505 (1994). The defendants claim alternatively that, even if it is assumed that an award of common-law punitive damages is merited, the award was improper because common-law punitive damages are limited to the plaintiffs’ litigation expenses, and there was no evidence in the present case concerning the plaintiffs’ litigation expenses. See Waterbury Petroleum Products, Inc. v. Canaan Oil & Fuel Co., 193 Conn. 208, 236, 238, 477 A.2d 988 (1984) (common-law punitive damages limited to expense of litigation less taxable costs).
Our review of the trial court’s memorandum of decision reveals, however, that the trial court awarded punitive damages under the Uniform Trade Secrets Act rather than under common law. The punitive damages provision of that act, namely, General Statutes § 35-53 (b), provides: “In any action brought pursuant to subsection (a) of this section,10 if the court finds wilful and malicious misappropriation, the court may award punitive damages in an amount not exceeding twice any award made under subsection (a) and may award reasonable attorney’s fees to the prevailing party.” (Emphasis added.) The trial court specifically quoted § 35-53 (b) in awarding punitive damages on the basis [470]*470of its finding that the defendants’ conduct was wilful and malicious. The only logical interpretation of the trial court’s decision, therefore, is that it awarded punitive damages under § 35-53 (b). The defendants do not dispute the trial court’s finding that their conduct was wilful and malicious. We conclude, therefore, that the trial court did not abuse its discretion in awarding $40,000 in punitive damages under § 35-53 (b) inasmuch as the award did not exceed twice the amount of the award of compensatory damages. See General Statutes § 35-53 (b).
D
Finally, the defendants claim that the trial court abused its discretion in awarding $20,000 in attorney’s fees. Specifically, the defendants claim that the award of attorney’s fees was improper because no evidence was presented to establish the reasonableness, nature and extent of the attorney’s fees incurred by the plaintiffs during the course of the litigation. We reject the defendants’ claim under the particular circumstances of this case.
The trial court was vested with discretion to award reasonable attorney’s fees under both CUTPA and the Uniform Trade Secrets Act. General Statutes § 42-1 lOg (d) provides in relevant part that, in any action in which a person alleges damages resulting from an unfair trade practice prohibited by § 42-110b of CUTPA, “the court may award, to the plaintiff, in addition to the relief provided in this section, costs and reasonable attorneys’fees based on the work reasonably performed by an attorney and not on the amount of recovery. ...” (Emphasis added.) Additionally, General Statutes § 35-53 (b), one of the provisions comprising Connecticut’s Uniform Trade Secrets Act, provides in relevant part: “[I]f the court finds wilful and malicious misappropriation, the court may award punitive damages in an [471]*471amount not exceeding twice any award [of compensatory damages] and may award reasonable attorney's fees to the prevailing party.” (Emphasis added.)
Notwithstanding the conclusive establishment of liability occasioned by the default of the defendants in the present case, “the plaintiff must still prove . . . how much of the judgment prayed for in the complaint he is entitled to receive.”11 (Internal quotation marks omitted.) DeBlasio v. Aetna Life & Casualty Co., supra, 186 Conn. 401. Thus, although Lectron was entitled to a discretionary award of reasonable attorney’s fees in light of the defendants’ liability, it was incumbent upon Lectron to prove the amount of fees to which it was entitled upon the entry of the default judgment.
We long have held that there is an “undisputed requirement that the reasonableness of attorney’s fees and costs must be proven by an appropriate evidentiary showing." (Emphasis added.) Hartford Electric Light Co. v. Tucker, 183 Conn. 85, 91, 438 A.2d 828, cert. denied, 454 U.S. 837, 102 S. Ct. 143, 70 L. Ed. 2d 118 (1981); accord Barco Auto Leasing Corp. v. House, 202 Conn. 106, 121, 520 A.2d 162 (1987); see also Appliances, Inc. v. Yost, 186 Conn. 673, 680-81, 443 A.2d 486 (1982); Stelco Industries, Inc. v. Cohen, 182 Conn. 561, 567-68, 438 A.2d 759 (1980). We also have noted that “courts have a general knowledge of what would be reasonable compensation for services which are fairly stated and described"-, (emphasis added; internal quotation marks omitted) Shapero v. Mercede, 262 Conn. 1, 9, 808 A.2d 666 (2002); and that “[c]ourts may rely on their general knowledge of what has occurred at the proceedings before them to supply evidence in support of an award of attorney’s fees.” (Internal quotation marks omitted.) Andrews v. Gorby, 237 Conn. 12, 24, [472]*472675 A.2d 449 (1996). Even though a court may employ its own general knowledge in assessing the reasonableness of a claim for attorney’s fees, we also have emphasized that “no award for an attorney’s fee may be made when the evidence is insufficient.” (Internal quotation marks omitted.) Appliances, Inc. v. Yost, supra, 680.
The weight of authority indicates that more than the trial court’s mere general knowledge is required for an award of attorney’s fees. See, e.g., Miller v. Kirshner, 225 Conn. 185, 201, 621 A.2d 1326 (1993); Barco Auto Leasing Corp. v. House, supra, 202 Conn. 120-21; Appliances, Inc. v. Yost, supra, 186 Conn. 681; Stelco Industries, Inc. v. Cohen, supra, 182 Conn. 567-68; Lebowitz v. McPike, 151 Conn. 566, 568, 201 A.2d 469 (1964); but see Bizzoco v. Chinitz, 193 Conn. 304, 310-11, 476 A.2d 572 (1984).
For example, in Appliances, Inc. v. Yost, supra, 186 Conn. 679, the terms of a promissoiy note provided for an award of reasonable attorney’s fees. The trial court nevertheless determined that the parties had failed to provide sufficient evidence for an award of attorney’s fees. Id. We disagreed, concluding that “some evidentiary material did exist for the court to consider on that issue”; id., 681; including a supplemental brief filed by the plaintiff in which the plaintiff itemized the attorney’s services. Id. We noted that “[t]hese materials, combined with the court’s own general knowledge, could serve to provide a basis for the court to decide the right to and amount of reasonable attorney’s fees.” (Emphasis added; internal quotation marks omitted.) Id.
In Piantedosi v. Floridia, 186 Conn. 275, 440 A.2d 977 (1982), the defendant claimed that the trial court improperly awarded attorney’s fees because it did not base its award on “factual evidence in the transcript, such as expert witness testimony.” Id., 279. We rejected the defendant’s contention, concluding that the trial [473]*473court properly considered evidence that “twenty-five hours, at $60 per hour, had been expended on the case before trial.” Id. We noted that a party need not present expert testimony regarding attorney’s fees and reaffirmed our previous holdings that “courts have a general knowledge of what would be reasonable compensation for services which are fairly stated and described.” (Emphasis added; internal quotation marks omitted.) Id.
Moreover, in Hartford Electric Light Co. v. Tucker, supra, 183 Conn. 86-87, the defendant appealed from the judgment of the trial court awarding, inter alia, attorney’s fees to the plaintiff. The defendant challenged the constitutionality of a statute that allowed for the plaintiff’s recovery of “reasonable attorney’s fees and costs . . . .” (Internal quotation marks omitted.) Id., 91. We rejected the defendant’s contention that the statute authorizing the plaintiffs recovery of attorney’s fees was “devoid of standards,” concluding that “[t]he defendant’s constitutional protection from excessive awards [was] to be found in the undisputed requirement that the reasonableness of attorney’s fees and costs must be proven by an appropriate evidentiary showing.” (Emphasis added.) Id.
In Miller v. Kirshner, supra, 225 Conn. 199, the defendant, Hal Kirshner, claimed that there was insufficient evidence to support an award of attorney’s fees. “During the trial on financial issues, the plaintiff [Mary Miller] submitted a sworn affidavit indicating that she owed counsel $20,000 at the time of trial and attached a supporting itemization. [Kirshner] argued that [Miller] was barred from seeking attorney’s fees because she had failed to produce expert testimony that the fees were reasonable. In its memorandum of decision on financial issues, the trial court awarded [Miller] $7000 in attorney’s fees. The court stated that ... [it had] a general knowledge of what would be a reasonable fee under [474]*474the facts, circumstances and workload of th[e] case. It [found that] amount to be fair and reasonable.
“[On appeal, Kirshner] claim[ed] that the trial court improperly [had] awarded attorney’s fees without conducting a hearing to consider evidence from an expert witness with respect to the reasonableness of the hours and monetary amount of the fees requested. [Kirshner did] not claim that he was not permitted to introduce evidence regarding the unreasonableness of the fees requested, but that [Miller had] failed to produce evidence, through an expert witness, of their reasonableness. [Kirshner] argue [d], therefore, that without a proper evidentiary foundation, an award of attorney’s fees could not be made.” (Internal quotation marks omitted.) Id., 199-200.
We disagreed with Kirshner and concluded that “[t]he trial court properly relied on the financial affidavit before it and, on its general knowledge and involvement with the entire trial to ascertain a reasonable attorney’s fee.” (Emphasis added.) Id., 201. Thus, the trial court possessed documentary evidence regarding attorney’s fees and based its award on that evidence in addition to its own general knowledge of what constituted a reasonable attorney’s fee. See id.
In Shapero v. Mercede, 262 Conn. 1, 808 A.2d 666 (2002), we reviewed the Appellate Court’s conclusion that there was insufficient evidence upon which to base a finding of attorney’s fees because the plaintiff attorney, Paul D. Shapero, had produced no evidence to establish either his rate of compensation or the prevailing rates in the legal community. We stated that “[t]he Appellate Court did not consider, however, whether there was other evidence that could have supported the fee award.” Id., 6.
Shapero testified that he had worked 100 hours on the matter. Id., 3. “[T]he referee based her finding that [475]*475the appropriate hourly rate was $275, rather than $500 as requested by [Shapero], upon other subordinate findings relevant to the value of [Shapero’s] services. With regard to [Shapero’s] experience and reputation, the referee noted that [t]he fact finder recognizes that the value added choice of [having Shapero] . . . handle the [client’s] tax matters involved the recognition of [Shapero’s] notable service as probate judge and as corporation counsel with the city of Stamford and other public boards and agencies and his lifelong service to the community and to the legal profession. [The referee] also found that [t]he arguments were complicated by the fact that a claim of environmental contamination was involved that could [have] triggered] a broader base for application of tax relief, and that [t]here [was] an element of novelty to [Shapero’s] presentation to the tax assessor regarding the assessment method and the list year in question ....
“The referee’s evidentiary findings with regard to [Shapero’s] experience and reputation, and the novelty and complexity of the legal issues addressed in the course of his work on behalf of [his client], ha[d] not been challenged and [were] therefore binding on this court.” (Internal quotation marks omitted.) Id., 8-9.
In Shapero, we concluded the court’s “general knowledge [of what constitutes a reasonable attorney’s fee] and the referee’s unchallenged findings relevant to the value of the plaintiffs services provided sufficient support for the challenged finding that $275 per hour was an appropriate measure of the value of those services.” Id., 10. Thus, as in numerous other cases, there was additional evidence in Shapero to support the trial court’s award of attorney’s fees.
In Shapero, we distinguished cases that the Appellate Court had relied on in reversing the trial court’s award of attorney’s fees. See id., 6-7 n.3. We noted that “[t]he [476]*476Appellate Court cite[d] several cases in support of its conclusion that [n]o award of attorney’s fees . . . may be made when the evidence on which to base the award is insufficient. . . . Although this is a correct statement of the law, the cases cited are distinguishable .... Specifically, in none of the cases cited has this court or the Appellate Court ruled that competent evidence regarding the value of legal services was introduced but that it did not suffice to support a finding regarding that value. Indeed, in the first case cited by the Appellate Court [namely, Appliances, Inc. v. Yost, supra, 186 Conn. 673], we reversed the ruling of the trial court and held that a brief in which counsel’s services were itemized, when taken with the court’s own general knowledge, constituted sufficient evidence from which to determine the amount of reasonable attorney’s fees. [Id., 681]. Therefore, in Appliances, Inc., we required neither evidence regarding the rate ordinarily charged by the plaintiff in that case nor evidence of prevailing rates in the community. In one of the other cases cited by the Appellate Court ... no evidence of the value of the services whatsoever had been introduced. Lebowitz v. Pike, [151 Conn. 566, 568, 201 A.2d 469 (1964)]. In another [namely, City Savings Bank of Bridgeport v. Miko, 1 Conn. App. 30, 467 A.2d 929 (1983)], the Appellate Court determined that the awarding of attorney’s fees would be improper because the post-deficiency-judgment services for which the fees were sought had not yet been performed, unlike those in question in [Shapero], and might never be performed in the future. [Id., 38]. That court ruled that [permitting an award of legal fees depends upon a factual finding concerning work already performed. Id. In the remaining case cited by the Appellate Court [namely, Gruskay v. Simenauskas, 107 Conn. 380, 140 A. 724 (1928)], the only evidence of the value of the attorney’s services was in the form of opinion testimony [477]*477provided by three witnesses in response to a hypothetical question regarding the attorney’s prior experience. [Id., 384-85]. An objection to the question was made on the grounds that it did not accurately reflect the actual level of experience of the attorney seeking compensation. Id., 384. This court concluded that the trial court improperly had overruled this objection . . . and held that [w]ith the hypothetical question excluded, there was no sufficient evidence before the court upon which to predicate a conclusion regarding the value of the services. Id., 387. [In Shapero] . . . there [was] such evidence.” (Citations omitted; emphasis added; internal quotation marks omitted.) Shapero v. Mercede, supra, 262 Conn. 6-7 n.3.
Thus, as our case law demonstrates, to support an award of attorney’s fees, there must be a clearly stated and described factual predicate for the fees sought, apart from the trial court’s general knowledge of what constitutes a reasonable fee. Although we have been careful not to limit the contours of what particular factual showing may suffice, our case law demonstrates that a threshold evidentiary showing is a prerequisite to an award of attorney’s fees.12
Notwithstanding the existence of numerous cases establishing this evidentiary burden, some confusion exists in our case law regarding the nature and extent of this evidentiary burden. See Resurreccion v. Normandy Heights, LLC, 76 Conn. App. 642, 650, 820 A.2d 1116 (acknowledging confusion relating to evidentiary burdens associated with awards of attorney’s fees), cert. denied, 264 Conn. 917, 826 A.2d 1159 (2003).
[478]*478The dissent relies on our holding in Bizzoco v. Chintz, supra, 193 Conn. 304, to support its conclusion that the trial court’s general knowledge of the file, per se, is sufficient for an award of attorney’s fees. In Bizzoco, the defendant, Leon Chinitz, appealed from the judgment of the trial court awarding the plaintiff, Elizabeth Bizzoco, attorney’s fees. See id., 306-307. The trial court awarded Bizzoco attorney’s fees pursuant to the explicit provisions of a promissory note authorizing an award of reasonable fees. Id., 310. Inasmuch as Bizzoco had offered no additional evidence regarding attorney’s fees at trial apart from the terms of the promissory note, Chinitz claimed that the evidence was insufficient to sustain an award of attorney’s fees. See id. We disagreed with Chinitz and held that “courts may rely on their general knowledge of what has occurred at the proceedings before them to supply evidence in support of an award of attorney’s fees.” Id. We noted that “the trial court knew that [Bizzoco’s] counsel had taken a lengthy deposition, had engaged in a two-day trial, and had prepared a post-trial brief.” Id., 310-11. We thus concluded that “[t]he [trial] court was in a position to evaluate the complexity of the issues presented and the skill with which counsel had dealt with these issues. Th[e] record was sufficient to support the award made by the court.” Id., 311.
We acknowledge that the dissent’s interpretation of our holding in Bizzoco, namely, that the trial court’s general knowledge of the reasonableness of the attorney’s fees as well as the court’s access to the file and knowledge of the proceedings before it was alone sufficient to warrant an award of attorney’s fees, is a reasonable interpretation of that case. Nevertheless, we believe, on the basis of the weight and persuasiveness of our case law on this issue, decided both before and after Bizzoco, that the trial court’s general knowledge of the file in a particular case, by itself, is an insufficient [479]*479foundation on which to base an award of attorney’s fees. Our adherence to the principle set forth in Bizzoco would require us to read the “fairly stated and described” language out of our long-standing precedent. (Internal quotation marks omitted.) Shapero v. Mercede, supra, 262 Conn. 9. We decline to do so. Furthermore, we note that, in support of our holding in Bizzoco, we cited to Appliances, Inc., and Piantedosi; Bizzoco v. Chintz, supra, 193 Conn. 310; two cases that clearly emphasize the necessity of having an evidentiary foundation, independent of the trial court’s general knowledge, upon which to base an award of attorney’s fees. See Appliances, Inc. v. Yost, supra, 186 Conn. 681; Piantedosi v. Floridia, supra, 186 Conn. 279.
Accordingly, when a court is presented with a claim for attorney’s fees, the proponent must present to the court at the time of trial or, in the case of a default judgment, at the hearing in damages, a statement of the fees requested and a description of services rendered.13 Such a rule leaves no doubt about the burden on the party claiming attorney’s fees and affords the opposing party an opportunity to challenge the amount requested at the appropriate time.14
[480]*480Our holding today does not limit the trial court’s ability to assess the reasonableness of the fees requested using any number of factors, including its general knowledge of the case, sworn affidavits or other testimony, itemized bills, and the like. As we recognized in Piantedosi, “[t]he value [of reasonable attorney’s fees] is based upon many considerations.” (Internal quotation marks omitted.) Piantedosi v. Floridia, supra, 186 Conn. 279, quoting Hoenig v. Lubetkin, 137 Conn. 516, 524, 79 A.2d 278 (1951).
In addition, as a matter of good policy, our holding today establishes a paradigm within which all parties must act when pursuing a claim for attorney’s fees. Perhaps, even more importantly, our holding eliminates the undesirable burden imposed upon the courts when a party seeks an award of attorney’s fees predicated solely upon a bare request for such fees. Parties must supply the court with a description of the nature and extent of the fees sought, to which the court may apply its knowledge and experience in determining the reasonableness of the fees requested.
Under the circumstances of this case, however, we affirm the trial court’s award of $20,000. We reach this conclusion because the defendants did not oppose or otherwise take any action in response to the plaintiffs’ request for $25,000 in fees in their post-damages hearing brief.15 Although the proponent bears the burden of [481]*481furnishing evidence of attorney’s fees at the appropriate time, once the plaintiffs in this case did make such a request, the defendants should have objected or at least responded to that request. Had the defendants demonstrated any interest in objecting to the plaintiffs’ request for attorney’s fees, the trial court would have been obligated to grant the defendants an opportunity to be heard. See Barco Auto Leasing Corp. v. House, supra, 202 Conn. 121; footnote 14 of this opinion. Accordingly, although a bare request for attorney’s fees, without more, ordinarily would not suffice under the clarifying rule we announce today, we conclude that a reversal of the award in the present case is not justified in light of the defendants’ failure, prior to this appeal, to interpose any objection whatsoever to the plaintiffs’ request for attorney’s fees. In other words, the defendants, in failing to object to the plaintiffs’ request for attorney’s fees, effectively acquiesced in that request, and, consequently, they now will not be heard to complain about that request.16
The judgment is reversed with respect to the trial court’s award of damages and attorney’s fees to the plaintiffs Patricia Smith and Carol Tartagni and the case is remanded to the trial court with direction to render judgment dismissing the action as to those two plaintiffs. The judgment is otherwise affirmed.
In this opinion SULLIVAN, C. J., and NORCOTT and PALMER, Js., concurred.
