This matter stems from three complaints filed against respondent following an audit of his books and records. The District VI Ethics Committee (Ethics Committee) found that respondent had engaged in conduct involving dishonesty and misrepresentation, in violation of DR 1-102(A)(4); had overreached clients in charging excessive fees, in violation of DR 2-106(D); had violated record keeping regulations, R. 1:21-6 and DR 9-102(B)(3) and (C); had failed to preserve the identity of client funds, in violation of DR 1-102(A); and had engaged in other *262activities adversely reflecting on his fitness to practice law, in violation of DR 1-102(A)(6). Although it found that respondent had misused trust funds, the Ethics Committee did not determine whether the misuse was knowing.
The Disciplinary Review Board (DRB) agreed substantially with the Ethics Committee’s findings. In addition, the DRB found that respondent knowingly misappropriated client funds in three separate matters. Accordingly, the DRB recommended that respondent be disbarred. Three dissenting members of the DRB found respondent’s misuse of client funds to be negligent and recommended a three-year suspension.
Our independent review of the record leads us to conclude that respondent knowingly misappropriated client funds and that he must be disbarred. Because of that conclusion, this opinion is concerned, to the exclusion of other allegations of attorney misconduct, solely with the issue of knowing misappropriation. Within that context, we further limit the opinion to the acts of misappropriation that occurred after the publication of In re Wilson, 81 N.J. 451, 409 A.2d 1153 (1979).
I
The record clearly and convincingly establishes that respondent knowingly misappropriated trust funds in two post-Wilson matters. In the first, his clients were James and Maryann Maguire, and in the second, his client was his cousin, Maurice Spagnoletti.
The DRB summarized the facts in these two matters:
In the Maguire matter, for instance, respondent deposited two checks in his trust account, one for $9,300 and the other for $1,000, representing the deposit tendered by the purchasers of the Maguires’ property. Those deposits were made on December 1, 1979, and January 9, 1980, respectively. Notwithstanding the fact that no disbursements were made on the Maguires’ behalf until March 31, 1980, the trust account balance was only $1,697.12 on December 31, 1979, $968.98 on January 7, 1980, $1,053.07 on January 31, 1980, and $12.98 on February 29, 1980. However, respondent should have held $10,300 in trust for the Maguires until March 31, 1980. Thus, the trust account shortage in Maguire ranged from more than $8,000 to more than $10,000. $8,000 of that *263shortage resulted from two payments to respondent in December: one check for $3,000 which cleared on December 12, 1979, and a second check for $5,000 payable to respondent, which cleared on December 17, 1979.
At the ethics hearing of January 14, 1987, respondent conceded that there was a trust account shortage in connection with the Maguire transaction. He testified that he was unable to explain the reason for the shortage as a result of the destruction of all his records by a fire in his office in late 1979. He recalled, however, that “there were monies that were supposed to come from (client) Malfettone which did not come which caused a shortage. And I believe the same day, I made a loan ... which satisfied the overdraft.” Indeed, the record shows — and respondent so admitted — that in April 1980 he obtained a $35,000 loan which he deposited in his trust account to cover a shortage in connection with “one of the two real estate transactions.” 1
Similarly, in the Spagnoletti matter, on June 18, 1980, respondent’s trust liability to his client consisted of $20,074.64. On that date, however, the trust account balance was only $18,137.68. From June 23 through July 7, 1980, respondent’s trust liability to Spagnoletti amounted to $15,051.44. On June 23, however, the trust account balance was only $12,022.04 and, by July 7, 1980, it had declined to $1,903.60. The three largest decreases in the trust account balance were the result of three checks of $3,000 each made payable to respondent. Those checks were dated July 1, July 2, and July 5,1980. (Exhibit P-9 attached to the complaint). The July 1 and July 2 checks were cashed on those same days; the July 5 check was cashed on July 7, 1980 (Exhibit P-8 attached to the complaint).

From these facts, the DRB concluded:
It matters not that respondent might not have utilized those funds for his own gain, as he contends. In re Wilson, supra, 81 N.J. at 455 n. 1 [409 A.2d 1153]; In re Noonan, [102 N.J. 157, 160, 506 A.2d 722 (1986).]
The record is replete with clear instances of knowing misappropriation of trust funds. In the absence of an outright admission, circumstantial evidence can lead to the conclusion that a lawyer knew or had to know clients’ funds were being invaded. Matter of Johnson, 105 N.J. 249, 258 [520 A.2d 3] (1987).
By respondent’s own admission, beginning in December, when he had a coronary bypass operation, and during the relevant times mentioned in the complaint, 1978 through 1980, “I really didn’t feel Jwas practicing law.” I had no “outside office. I was using my home. I wasn’t listed. I (did not) believe I had an office phone. I didn’t have a secretary____ I had no sign; and I didn’t *264solicit any business. The only work I was doing was for people I had a personal relationship with.” Accordingly, respondent cannot argue that the volume of his practice, combined with the fact that he was a sole practitioner, precluded him from closely examining his trust account records and that, consequently, any misuse of client funds was negligent, not intentional. As the Court stated in Matter of Johnson, supra, 105 N.J. at 260 [520 A.2d 3] (1987):
[W]e do not intend to suggest that henceforth a respondent who just walks away from his fiduciary obligation as safekeeper of client funds can expect this Court to take an indulgent view of any misappropriation. We will view “defensive ignorance” with a jaundiced eye. The intentional and purposeful avoidance of knowing what is going on in one’s trust account will not be deemed a shield against proof of what would otherwise be a "knowing misappropriation.” There may be semantical inconsistencies, but we are confident that within our ethics system, there is sufficient difference between intentional ignorance and legitimate lack of knowledge.
[Transcript references omitted.]
In Wilson, we declared, in now familiar language, that a misappropriation is “any unauthorized use by the lawyer of clients’ funds entrusted to him, including not only stealing, but also unauthorized temporary use for the lawyer’s own purpose, whether or not he derives any personal gain or benefit therefrom.” 81 N.J. at 455 n. 1, 409 A.2d 1153. Knowing misappropriation “consists simply of a lawyer’s taking a client’s money entrusted to him, knowing that it is the client’s money and knowing that the client has not authorized the taking.” In re Noonan, 102 N.J. 157, 160, 506 A.2d 722 (1986). In both the Maguire and Spagnoletti matters, as the DRB concluded, “the record is replete with clear instances of knowing misappropriation of trust funds.”
Our examination of the record reveals that during the period he handled the Maguire and Spagnoletti matters, respondent used his trust account both as a business account and as a personal account to accommodate some of his friends, generally elderly acquaintances whose bills respondent paid. Respondent regularly paid these bills regardless of whether sufficient funds were in his trust account to cover the expenditures. The practice began before the publication of Wilson and continued thereafter. Respondent described his use of trust funds for his friends in the late 1970s:
*265A. Well, at the time, I know I had a lot of personal problems; and, quite honestly, I don’t think I was putting in the attention to the accounts that probably normally I would have had before 1976.
But I had records. I knew who had money in the account, and who had to give me money, you know, at all times.
Q. Well, would it ever come an occasion where you made an advance for [your friend], and he owed the money, and you paid out money on his behalf despite the fact that you didn’t have it?
A. (No response.)
Q. You didn’t have it from him to make the disbursement?
A. Oh, yeah. That happened a number of times.
Q. And would that be the reason that your trust account might have been deficient in those areas by virtue of doing the work you were doing for these particular [friends]?
A. Well, at certain times, yeah, I would assume it would.
Respondent justifies his misuse of clients’ funds because of his personal problems. In 1975, respondent’s father died, and in the following year, respondent underwent double bypass heart surgery. After this operation, respondent essentially ceased accepting clients. He completed pending matters and accepted new matters from friends only. In 1977, respondent’s brother committed suicide. The following year respondent developed a nervous condition and impotency due to a diabetic condition. In 1979, because of an automobile accident, he was hospitalized for one month with two herniated discs and related back ailments. In December of that year, his residence, in which his office was located, burned down. Finally, in May 1980, his mother suffered a stroke.
The thrust of respondent’s argument is that his personal problems so distracted him that he could not diligently manage his trust account. He admitted, however, that he knew that it was unethical to use client funds without authorization. Furthermore, contrary to his asserted inability to manage his trust account from 1978 to 1980, respondent perceived himself during this period as possessing sufficient financial expertise to manage the affairs of others. In this regard, he testified:
Q. Now, going back to the Maguire real estate transactions with Burch [the pre-Wilson matter], could you, as an attorney since 1960 — did you understand *266that when you received the funds of $9300 and $1000, that these funds were to be held by you and not to be disbursed until the closing?
A. As a lawyer, as a matter of general knowledge, of course, I know that I have to say, though, my state of mind was such that whatever you want to call it, neglect, lack of concern, whatever * * *.
********
I was not conducting a law practice, although I may have filed a tax return listing myself as a lawyer; but I certainly was not the same lawyer I was * * *.
Q. I won’t argue with you; but despite the fact that you might not have been the same lawyer that you were, you did know even at that time that this is what was supposed to be done with the money?
A. I admit that, yes.
Q. Mr. Bell, other than your practice as an attorney at law, would you consider yourself to have any expertise in any other area.
A. Yes.
Q. What area would that be?
A. Financial.
Q. During the years 1978, 1979, and 1980, would you still have considered yourself to be an expert in the area of finances?
A. Yes.
Respondent does not deny that using his business account as a trust account was improper or that his record keeping was shoddy and haphazard. Lawyers, as we have said, “have a duty to assure that their accounting practices are sufficient to prevent misappropriation of trust funds.” In re Fleischer, 102 N.J. 440, 447, 508 A.2d 1115 (1986). As fiduciaries, lawyers are obliged to know whether their trust accounts are in balance. Here, the conclusion is inescapable that respondent knew he was using client funds without authorization. It makes no difference that respondent did not use any of the funds for his own purposes or that no client suffered from his misappropriation. In re Noonan, supra, 102 N.J. at 160, 506 A.2d 722.
Respondent’s claim that his physical and mental problems excuse or mitigate his misappropriations are likewise unavailing. Nothing in the record establishes that his problems caused his misappropriations. In re Jacob, 95 N.J. 132, 137, 469 A.2d 498 (1984). Absent a “demonstration by competent medical proofs that respondent suffered a loss of competency, comprehension or will of a magnitude that could excuse egregious *267misconduct,” his physical or mental condition will not excuse the knowing misuse of client funds. Ibid.
II
Although respondent may have endured more grief within several years than many endure in a lifetime, his suffering did not prevent him from knowing what he was doing when he misused client funds. Accordingly, we find that respondent knowingly misappropriated funds in violation of DR 9-102 and must be disbarred.
Respondent shall reimburse the Ethics Financial Committee for appropriate administrative costs, including the costs of transcripts.
Respondent admitted to allegations of the Ethics Committee complaint that on April 19, 1980, he was out-of-trust to the Maguires by over $21,000. The Ethics Committee established the deficit by deducting from the proceeds of the sale of the Maguire’s existing home the costs of that sale and of the purchase of their new home. On April 14, respondent brought the account into balance by depositing the above-described $35,000 loan.
