The plaintiffs’ amended complaint sought to recover damages from the defendants, both lawyers, on allegations (1) that Gerstein had committed malpractice in representing them in connection with a suit to restrain a mortgage foreclosure; (2) that his conduct also violated G. L. c. 93A; and (3) that Weiner, who practiced law with Gerstein, was derivatively liable for Gerstein’s actions as his “partner by estoppel.” The common law claims were tried to a jury; the c. 93A claim to the judge.

Burley,
In deciding whether the judge acted properly in entering judgment notwithstanding the verdict on the common law claims, we apply the standard applicable to a.motion for directed verdict.
D’Annolfo
v.
Stoneham Housing Authy.,
Viewing the evidence in this light, we conclude that the jury could have found the following. 4 In 1975, the plaintiffs owned a parcel of commercial property in Wenham which they had purchased in 1967. The parcel contained a building, a major part of which was leased to Richdale Dairy Stores, Inc., for the operation of a convenience store, and the balance of which was rented to a second store under a tenancy at will. In the summer of 1974, the mortgagee on the property, Danvers Savings Bank (bank), claimed a default in the mortgage, an assertion which the plaintiffs contested. They consulted Gerstein, and, at Gerstein’s request wrote a letter detailing to him their dispute with the bank. 5 In January, 1975, the plaintiffs formally retained *561 Gerstein “to bring suit against the . . . bank for breach of contract” based on the bank’s alleged mishandling of their loan. 6 Gerstein advised the plaintiffs “not to have anything to do with the [bank because] ... he would handle everything.”
By letter dated April 18, 1975, the bank notified the plaintiffs that its board of investment had voted to commence foreclosure, that future payments on the loan would not be accepted, and that the plaintiffs would be liable for any deficiency resulting after foreclosure. Gerstein assured the plaintiffs “not to worry about [the notice] . . . [t]hat he would take care of everything [a]nd that he was drawing up papers to file against the bank.”
Shortly after June 13, 1975, the plaintiffs received from the bank’s attorneys a copy of the order of notice issued by the Superior Court on the bank’s complaint to foreclose the mortgage. Gerstein also received a copy of this notice and again assured the plaintiffs “not to worry . . . that it [the foreclosure] wouldn’t happen [because] he would take care of everything.”
On July 30, 1975, the plaintiffs received written notice advising them that a foreclosure sale would be held on or after September 3, 1975, and that they would be liable for any resulting deficiency. The Browns promptly brought this notice to Gerstein’s attention. Gerstein advised them that an amended complaint was being prepared, 7 and made no mention of any problems.
*562 On August 1, 1975, the plaintiffs signed and swore to an amended complaint. This complaint alleged that the bank was solely responsible for the mortgage default, and that it had improperly refused to allow the plaintiffs to cure the default. The complaint sought preliminary inj unctive relief to enjoin the foreclosure as well as an accounting and damages. Gerstein told the plaintiffs that he would file the complaint in the Superior Court. Shortly thereafter he advised the plaintiffs that he had in fact filed the complaint that “there would be no foreclosure.” The plaintiffs relied on these assurances. Gerstein never filed the com"plaint. He did not tell the plaintiffs that it had not been filed or that neither a temporary restraining order nor an injunction would be applied for.
On August 15, 1975, the plaintiffs received a copy of the bank’s legal advertisement of the foreclosure sale which had been published in a local newspaper. This notice set the foreclosure sale at 2:00 p.m. on September 3, 1975. The notice was immediately brought to Gerstein’s attention. Gerstein advised the Browns that “everything was being held in abeyance” and “that there would be no foreclosure.” On August 28, 1975, Richard Brown met Gerstein. He again told Brown that “there wasn’t going to be any auction sale and that he (Gerstein) might . . . have a customer for the property.” These representations were false. 8 The *563 property was sold to a third party at foreclosure auction on September 3, 1975, for $62,000 without the plaintiffs’ knowledge.
When the plaintiffs discovered that the property had been sold they confronted Gerstein, who then told them that he had had a “deal” with the bank’s attorney, see note 8, supra, and that this lawyer had “double-crossed him.” Gerstein recommended that the plaintiffs file an immediate suit against the bank and its counsel and assured the Browns that he would appear as a witness on their behalf at the trial. To this end, Gerstein directed the plaintiffs to another lawyer in his office. This lawyer prepared yet another complaint against the bank. This complaint, seeking damages, accused the bank of bad faith and repeated the substance of the amended complaint with one difference; it contained an assertion that at the time of the foreclosure sale “the plaintiffs were . . . financially unable to purchase the property.” 9 The plaintiffs reviewed the complaint and swore to its contents. The attorney, however, declined to represent the plaintiffs after receiving information from the bank’s counsel which made it doubtful that the plaintiffs could prevail at trial. As a result, the complaint was never filed and the lawyer terminated his relationship with the plaintiffs after telling them that he had returned their file to Gerstein.
There was testimony that Gerstein never advised the plaintiffs of options to prevent foreclosure. 10 The judge excluded testimony, preserved by a proper offer of proof, that had the Browns known that Gerstein had not filed the com *564 plaint and that the foreclosure sale would take place, they would have sought to avoid the sale by: (1) engaging another attorney to file suit and seek an injunction on a different theory of law, 11 (2) curing the default by paying the arrearage, 12 (3) attempting to sell the property or to refinance the debt with another lender, (4) attending the foreclosure sale with the required deposit either to purchase the property or to bid it up to full market value, or (5) discharging the mortgage by paying the entire indebtedness. There was further testimony that the plaintiffs had funds, independent of borrowing, which could have been used for these purposes. These funds were contained in two trusts for the benefit of Ann Brown. The first was a personal trust containing about $30,000, the terms of which permitted payments of principal to Ann Brown in the sole discretion of the trustees. The second was a testamentary trust, containing about $70,000. Ann Brown could obtain principal from the latter trust “as she deem[ed] advisable.” The annual income from the testamentary trust averaged $4,000. In addition to the assets of the trusts, there was testimony that the plaintiffs had substantial equity in their home.
A few other facts are relevant to the discussion of the common law claims. The measure of damages was stipulated to be the difference between the $62,000 paid by the *565 buyer at the foreclosure sale and the fair market value of the premises. There was evidence which would have warranted a finding that, on September 3, 1975, the premises had a fair market value of at least $100,000. The judge considered the common law malpractice claims as solely limited to Gerstein’s negligence in failing to file the amended complaint. On this hypothesis, the judge instructed the jury that the plaintiffs could recover only if they found that an injunction could have been obtained on the facts alleged in the amended complaint, declining to put to the jury the question whether Gerstein was liable for deceit.
1. We first consider the common law claims of malpractice. It is conceded that an attorney-client relationship existed between Gerstein and the Browns and that Gerstein was negligent in failing to file the amended complaint. We are satsified that the judge properly rejected the plaintiffs’ claim that the foreclosure would have been enjoined for the reasons stated in his memorandum on the motion for judgment n.o.v. In that memorandum, the judge pointed out that the plaintiffs had to establish that they “would have succeeded in the underlying litigation but for the attorney’s negligence in not bringing suit.” See
McLellan
v.
Fuller,
The plaintiffs argue, however, that Gerstein was negligent because he failed to advise them of alternatives to avoid foreclosure (and in the case of the remedy allegedly provided by G. L. c. 244, § 22, because he failed to find and plead that statute), and that Gerstein was liable for deceit. Because of this conduct, the Browns claim they were unable to take action which would have saved their property. The *566 defendants argue, on the other hand, that the judge properly kept these theories from the jury because (1) Gerstein was hired only to prepare, file and try the amended complaint and not to give general advice on other avenues that might prevent foreclosure, (2) in any event, expert testimony was necessary to establish that a lawyer in Gerstein’s position would have given advice about such alternatives, (3) deceit was never pleaded and tried, and (4) there was insufficient proof that if any of the alternatives had been pursued, the foreclosure could have been avoided.
We think the plaintiffs cannot prevail on their theory that Gerstein was negligent in failing to advise them of the options to avoid foreclosure, see note 10,
supra.
The only evidence concerning the scope of Gerstein’s employment confined his representation to “bringing] suit against the . . . bank for breach of contract.” Whether a lawyer whose employment was so limited would undertake to give his client general advice about ways to avoid foreclosure was a subject requiring expert testimony in accordance with the rule that “expert testimony is generally necessary to establish the standard of care owed by an attorney in the particular circumstances and the defendant’s alleged departure from it.”

This does not end the matter, however, because we must consider whether the evidence was sufficient to hold Ger-

“Fraud or deceit ... is no more a necessary incident to the rendition of legal services than dishonesty is to any other profession. The avoidance of fraudulent conduct requires no special skill or knowledge, but only basic precepts of honesty and integrity. When committed by an attorney, the tort of fraud or deceit is determined by essentially the same rules that apply to any defendant, regardless of whether he is a professional.” Mallen & Levit, Legal Malpractice § 107 (2d ed. 1981). See S.J.C. Rule 3:07, DR 1-102(A)(4), as appearing in
2. We then come to the question whether any damage resulted from the deceit. See
Szpiro
v.
Corkin,
*569
3. We next take up the plaintiffs’ assertion that the judge erred in the disposition of their claim under G. L. c. 93A. The plaintiffs concede that they could not recover under § 9 of c. 93A because no demand letter was sent to the defendants. See
Slaney
v.
Westwood Auto, Inc.,
In deciding whether Gerstein’s alleged wrongdoings occurred within the conduct of trade or commerce as required by § 2(a) of c. 93A, we find the decision of
Guenard
v.
Burke,
While the issue raised here is not expressly discussed in Guenard, that decision in straightforward fashion applies c. 93A to the attorney-client relationship. We consider Guenard to be authority for the proposition that in circumstances like those here present the practice of law constitutes “trade or commerce” for purposes of liability under c. 93A. We, therefore, proceed no further to ponder the relevance of the private action decisions to c. 93A claims arising out of the attorney-client relationship.
The question whether the plaintiffs were engaged in trade or commerce (a prerequisite to recovery under § 11),
21
*571
was one for the judge as the trier of fact. The evidence warranted a finding that the plaintiffs as lessors of commercial property (and perhaps as commercial clients of Gerstein) were acting in a business context and thus engaging in “trade or commerce.” See
Linthicum
v.
Archambault,
4. We reach the plaintiffs’ argument that, under the doctrine of partnership by estoppel, Weiner is liable to the same extent as Gerstein. 23
The common law doctrine of partnership by estoppel is codified for the Commonwealth in G.L. c. 108A, § 16. See
Standard Oil Co.
v.
Henderson,
*572 In setting aside the verdict against Weiner, the judge concluded that the evidence was insufficient to satisfy the second requirement, viz., that any holding out was done directly by Weiner or with his consent. On this issue, there was evidence that on October 16, 1972, the Browns had made a check payable to “Gerstein and Weiner” (apparently for legal services unrelated to the instant case) which was deposited in “Gerstein and Weiner clients’ account”; that in 1975, in connection with the pending foreclosure, the plaintiffs made out a retainer check in the amount of $150 payable to Gerstein alone; that the plaintiffs thereafter received letters from Gerstein on stationery bearing the legend “Ger-stein and Weiner;” and that Gerstein testified in his deposition that Weiner knew that he (Gerstein) was using Gerstein and Weiner stationery. There was no evidence that the plaintiffs ever met Weiner or that Weiner rendered any legal services on their behalf.
The judge’s conclusion was correct. The evidence concerning the 1972 check and the account in which it was deposited is irrelevant to establish consent in connection with the 1975 transactions before us. It is of significance that the 1975 retainer check was made payable to Gerstein alone. Hence the plaintiffs’ proof on consent came down to Weiner’s knowledge that his name was being used on the office stationery. The
Henderson
decision (at 326) establishes, however, that the use of a person’s name in a business, even with that person’s knowledge, is too slender a thread to warrant a favorable finding on the consent element. See also
Joseph
v.
Greater New Guide Baptist Church, Inc.,
5. Two issues that may arise upon retrial may be disposed of summarily.
(a) Although the attorney-client relationship is essentially contractual in nature, the claims to be retried (deceit and c. 93A) basically sound in tort. Consequently, if the plaintiffs prevail after retrial, interest on any sum recovered should be computed in accordance with G. L. c. 231, § 6B.
*573 (b) Retrial of the case will follow the usual judicial assignment procedures in the Superior Court.
6. To sum up: There is to be a new trial limited to (a) whether Gerstein’s conduct constituted deceit which prevented the plaintiffs from paying the bank’s mortgage in full and (b) whether Gerstein’s deceit violated G. L. c. 93A, §§ 2(a) and 11. On the balance of the claims against Ger-stein, the plaintiffs have failed in their proof, as they also have on their claim of derivative liability on Weiner’s part.
The judgment insofar as it disposes of the claims against the defendant Gerstein except those identified above is affirmed. The balance of the judgment for Gerstein is reversed and a new trial ordered consistent with this opinion. The judgment insofar as it relates to the defendant Weiner is affirmed.
So ordered.
Notes
The motion, despite its label, was a motion filed under Mass.R.Civ.P. 41(b)(2),
We recount here the facts that the jury could have found against Gerstein, leaving until later the evidence pertinent to the claims against Weiner.
These difficulties stemmed principally from a disagreement with Richdale over the parties’ respective obligations under the lease. Richdale had *561 paid a one-third share of the fuel bills owed by the Browns and deducted that amount from rent due under the lease. Richdale also made extensive repairs to the leased property and deducted the cost of the repairs from the rent, claiming that the plaintiffs had wrongfully refused, after notice, to make the repairs. The rent had been assigned to the bank as collateral security for the mortgage. The plaintiffs claimed that Richdale’s diversion of the rent caused the default in the mortgage payments.
At this time, the plaintiffs paid Gerstein a retainer by check and agreed with him that they would be billed periodically at a stipulated hourly rate for his services.
On July 14, 1975, the plaintiffs had received a copy of an original complaint prepared by Gerstein. After reviewing this complaint, the plaintiffs suggested some minor corrections and returned it to Gerstein for redrafting.
On September 2, 1975, Gerstein telephoned the bank’s attorney, who had previously stated to Gerstein that the bank did not prefer to foreclose and that it would not have to do so if the plaintiffs were able to sell the property and pay off the mortgage. Gerstein represented to the bank’s counsel that a purchase and sale agreement had been executed to sell the property for $85,000, that he was holding a $5,000 deposit, and that a separate side agreement had been executed by the plaintiffs and the purchaser for the sale of the fixtures. The bank’s attorney told Gerstein to deliver a copy of the purchase and sale agreement to him and indicated that he would consider postponing the next day’s foreclosure sale if everything appeared in order. On the morning of September 3, 1975, Gerstein delivered an unsigned purchase and sale agreement to this lawyer’s office and a hand-written note stating, “I am holding the $5,000 deposit.” On investigation, counsel for the bank learned that no purchase and sale agreement had been signed and that Gerstein’s representations were false. The foreclosure sale went forward as scheduled.
The amended complaint prepared by Gerstein did not contain an express allegation that the plaintiffs had the money to pay the mortgage but did aver that “[w]hen the [p]laintiffs finally ascertained the status of their account and the amount of the deficiency, it became too late for them to pay the amount due.”
More specifically, Brown testified that Gerstein did not advise the plaintiffs that they could: (a) refinance the debt with another bank, (b) discharge the mortgage by payment of the balance due on the note, (c) reinstate the mortgage by payment of the arrearages, or (d) apply for an injunction on a theory of law other than one of those stated in the amended complaint.
The alternate theory of law relied upon by the plaintiffs concerns the application of G. L. c. 244, § 22. They maintain that this statute permitted them to obtain an injunction stopping the foreclosure as matter of right. They contend that Gerstein was negligent in not bringing this statute to their attention or using it to enjoin the sale. They also claim that if they had discharged Gerstein and retained another lawyer, their new counsel would have invoked the statute to obtain an injunction. The judge refused to take judicial notice of the statute or to advise the jury of its provisions.
There was evidence that the arrearages as of April 18, 1975, totaled $1,636.85, and on the date of the sale (September 3, 1975), totaled $5,127.35. The principal due on the mortgage on September 3, 1975, weis approximately $58,000. Over the plaintiffs’ objection, the judge excluded deposition testimony of the deceased chief mortgage officer of the bank that the bank would have accepted payment of the arrearages and reinstated the mortgage.
Objections to questions by the plaintiffs’ counsel which were aimed at eliciting such opinions from the lawyer for the bank were properly sustained (if for no other reason) for lack of qualification of this lawyer as an expert and because the questioning on the subject exceeded the limit of permissible redirect examination.
There is no merit to the defendant’s contention that the plaintiffs never pleaded or tried a deceit claim. Paragraph 12 of the amended complaint bespeaks this claim, and the record leaves no doubt that the plaintiffs’ evidence raised the theory. Moreover, the plaintiffs requested jury instructions on deceit. It was the judge’s obligation to instruct the jury correctly on the general principles of law applicable to the pleadings and evidence in the case. The parties’ skirmishing over whether “fraud” was involved is beside the point. In the context of this case, the concepts of fraud and deceit are interchangeable. See
Nei
v.
Burley,
There was no evidence that the bank’s board of investment would have allowed the Browns to cure the default and continue payments in the future. The testimony of the bank’s chief mortgage officer, see note 12,
supra,
that the bank would have accepted payment of the arrearages was
*568
properly excluded since there was no evidence that he was authorized, either expressly or impliedly, to take action contrary to the decisions of the board of investment. See
Kanavos
v.
Hancock Bk. & Trust Co.,
There was no evidence that that it was
probable
that a sale or remortgage could have been successfully consummated in the short period facing the plaintiffs. The fact that the plaintiffs had negotiated a remortgage with the bank after they had defaulted on a previous mortgage with another bank would not support an inference that sale or remortgage was a likely prospect. This is particularly so in view of the plaintiffs’ debts and other encumbrances on the property. The plaintiffs’ evidence on the issue thus assumed the success of their goals and did not warrant the several inferences they now urge “based on probabilities rather than possibilities.” Alholm
v. Wareham,
In addition to the payment of a $3,500 deposit, the foreclosure sale was made subject to other terms to be announced at the sale. The record contains no evidence as to what these terms were and no evidence that the plaintiffs could have complied with them. Their proof on this issue is therefore subject to the same infirmity discussed in note 16, supra.
The evidence was not sufficient to warrant a finding that the plaintiffs could have withdrawn funds from the smaller personal trust to pay the indebtedness in full since there was no evidence that the trustees of that trust would have exercised their discretion to permit the withdrawal of principal which was not enough in any event to satisfy the whole indebtedness. There also was no evidence that the plaintiffs could have successfully remortgaged their home within the applicable time constraints.
The defendants argue that the Browns cannot recover for deceit because of the doctrine of “judicial estoppel”. This argument is based on *569 the assertion that the plaintiffs swore to a complaint, prepared by Gerstein’s associate after the foreclosure sale, which states that the plaintiffs were, at the time of the sale, “financially unable to purchase the . .. property”; an assertion at odds with their trial testimony. We are not persuaded by the argument.
While the doctrine of judicial estoppel has been recognized in various contexts by the Federal courts, see
Keystone Driller Co.
v.
General Excavator Co.,
The defendants also make a vague argument that the plaintiffs are precluded because they never advised Gerstein that they had the financial ability to pay off the mortgage. Assuming the point would have relevance, there was no testimony to support the alleged fact.
The Guenard case was decided after the trial of this case.
Section 11 of c. 93A, unlike § 9, requires that the plaintiff also be a “person who engages in . . . trade or commerce.” Section 11 does not require a demand letter as a prerequisite to suit.
We reject the defendants’ contention that the Guenard case should be distinguished on the basis that it involves a violation of ethical rules, hence a more serious infraction than the deceit complained of here. As previously noted, deceit also violates a lawyer’s ethical duty.
There was no evidence that Gerstein and Weiner were members of an actual partnership.
