OPINION
HUSPENI, Judge.*In this consolidated appeal, appellants Robert H. Williams and Robert K. Williams challenge the dismissal of their surcharge action against respondent-trustee Norwest Bank Minnesota, National Association (Nor-west), contending the district court erred in concluding that (1) a corporate trustee may rely upon an exculpatory clause in a trust instrument; and (2) the language of the particular exculpatory clause at issue here protects Norwest. Norwest also appeals,1 contending the district court abused its discretion by denying payment of attorney fees from the corpus of the trust and> erred in releasing Norwest’s co-trustees, Robert H. Williams and Margaret Linstroth, from liability. We affirm in part, reverse in part, and remand.
FACTS
In his last will and testament, dated August 22, 1949, and codicil thereto, dated August 29, 1950, James T. Williams created a trust. The original corporate trustee was Northwestern National Bank of Minneapolis. Northwestern changed its name, first to Nor-west Bank Minneapolis, National Association, and then to Norwest Bank Minnesota, National Association. From 1979 until 1997, the trustees were appellant Robert H. Williams, Margaret Linstroth, and respondent Nor-west.
*746Under Minn.Stat. § 501B.23 (1998), the Williams trust is subject to the continuing supervision of the district court. The trustees’ accounts of the trusteeship from the trust’s inception through December 31, 1989 have been filed with the district court and were duly settled and allowed by prior orders of the court.
James T. Williams, the trust’s creator, was the founder of the Creamette Company, and Creamette stock originally accounted for 98% of the trust’s value. In 1979, Creamette was acquired by Borden, Inc. As part of the Borden acquisition, the trust’s Creamette stock was exchanged for Borden common stock. As of January 1,1980, nearly 100% of the total market value of the trust was in Borden stock. The trust owned 630,948 shares of Borden stock at that time.
Beginning in 1980, the trustees began selling shares of Borden stock because of a perceived need to diversify trust assets. As of December 31, 1989, the last date through which trusteeship accounts have been settled and allowed by the district court, the trust owned 600,000 shares of Borden common stock at a value of $36,375 per share, and that stock accounted for 39.3% of the total market value of the trust.
From 1990 through 1994, the trustees generally voted to defer further divestment of Borden stock. The Williams trust’s board of trustees makes decisions by majority vote, so although Robert Williams moved to sell Borden stock, Norwest and Linstroth were able to defeat the motions. Norwest and Lin-stroth apparently felt that it would be prudent to hold Borden stock until the price of the stock rose in value. Borden stock ultimately lost value. The trustees disposed of most of the trust’s Borden stock by exchanging it for RJR Nabisco stock. For purposes of this stock exchange, Borden common stock was valued at $14.25 per share. Because Borden stock was previously valued at $36,375 per share, this exchange represented a significant loss in the value of the trust.
By petition dated June 6, 1996, trustees Linstroth and Norwest sought approval of the trustees’ annual accounts for the trusteeship from 1990 to 1995. Appellant Robert H. Williams filed objections to the petition, claiming that Norwest, as corporate trustee, was responsible for the trust’s loss in value from 1990 to 1995 and should be surcharged for the trust’s losses.
Norwest eventually asserted that article VIII, section 12 of the trust instrument protects it from liability. That clause states:
No Trustee shall be liable for the default or doing of any other Trustee, whether the act be one of misfeasance or nonfeasance, nor shall he be held liable for any loss by reason of any mistake or errors of judgment made by him in good faith in the execution of the trust.
The district court dismissed the action against Norwest on the basis of this clause because the court found that Norwest did not act with malfeasance and therefore was not liable.
ISSUES
I. May Norwest, as corporate trustee, use the exculpatory clause in the trust instrument as a shield to liability for breach of trust without violating public policy?
II. Does the exculpatory clause at issue shield Norwest from liability?
III. Did the district court abuse its discretion in refusing to award attorney fees from the corpus of the trust?
IV. Did the district court err by ruling that Linstroth and Williams would be released from liability for their administration of the trust?
ANALYSIS
I. Public policy
Where the critical evidence in interpreting a trust instrument is documentary, this court engages in de novo review. In Re Trust of Ward, 360 N.W.2d 650, 652 (Minn.App.1985), review denied (Minn. March 29, 1985). Here, the exculpatory clause in question is part of the trust instrument, and thus our review of the meaning and significance of that clause is de novo.
Appellant contends that allowing corporate trustees to use exculpatory clauses as a shield to liability for breach of trust vio*747lates public policy. We disagree. In Schlobohm v. Spa Petite, Inc., 326 N.W.2d 920 (Minn.1982), and Walton v. Fujita Tourist Enterprises Co., 380 N.W.2d 198 (Minn.App.1986), review denied (Minn. March 21, 1986), Minnesota courts examined exculpatory clauses generally and held that such clauses are valid so long as two conditions are met. Before enforcing an exculpatory clause, Minnesota courts look to see
(1) whether there was a disparity of bargaining power between the parties (in terms of a compulsion to sign a contract containing an unacceptable provision and the lack of ability to negotiate elimination of the unacceptable provision) and (2) the types of services being offered or provided (taking into consideration whether it is a public or essential service).
Schlobohm, 326 N.W.2d at 923 (citations omitted).
Here, there is no evidence suggesting either that there was a disparity of bargaining power between Norwest and the trust’s creator, James T. Williams, or that Norwest somehow compelled Williams to add the exculpatory clause. Moreover, numerous organizations are able to act as corporate trustees, and this particular trust was designed to benefit only private individuals. Thus, service as a corporate trustee for the Williams trust does not appear to be the type of public or essential service discussed in Schlobohm. We conclude that Norwest may raise the exculpatory clause in this case without violating Minnesota’s public policy.
II. Application of the exculpatory clause to Norwest
A. The first portion of the clause
In administering a trust, the court’s role is limited to fulfilling the donor’s intent, and that intent is “to be gathered from the whole instrument and all reasonable inferences that may be drawn from it.” Ward, 360 N.W.2d at 652. Generally, exculpatory clauses are not favored by the law and are strictly construed against the benefited party. Schlobohm, 326 N.W.2d at 923. If an exculpatory clause is either ambiguous in scope or attempts to release the benefited party from liability for intentional, willful, or wanton acts, the clause will not be enforced. Id.
Here, the district court found that under the Williams trust instrument, “trustees cannot be held liable for any act of misfeasance or nonfeasance but only for acts of malfeasance.” However, the “misfeasance or nonfeasance” portion of the clause states that “[n]o trustee shall be liable for the default or doing of any other trustee,” thereby preventing a trustee from incurring liability only for the acts of other trustees. The clause does not protect a trustee from his or her own act of misfeasance or nonfeasance; the clause only relieves a trustee of liability for his or her own acts when loss is suffered “by reason of any mistake or error of judgment made by [the trustee] in good faith in the execution of his trust.” Thus, while there may be situations in which the exculpatory clause will eliminate a trustee’s liability, the “misfeasance or nonfeasance” portion of the clause does not define those situations.
B. The second portion of the clause
Norwest contends that even if the district court incorrectly interpreted the clause, that portion relieving a trustee of liability for mistakes or errors of judgment made in good faith applies to Norwest’s benefit. See Myers v. Price, 463 N.W.2d 773, 775 (Minn.App.1990) (appellate court will affirm the judgment if it can be sustained on any grounds), review denied (Minn. Feb. 4,1991). Appellant argues that this language cannot aid Norwest because Norwest was negligent in failing to vote to divest the trust of Borden stock, and the language of the exculpatory clause does not exculpate a trustee for negligence.
We note initially that courts have long distinguished between negligence-type claims and mistakes or “mere errors of judgment.” See Sjobeck v. Leach, 213 Minn. 360, 365, 6 N.W.2d 819, 821-22 (1942) (“Mere error of judgment * * * does not create liability.”); In re Will of McCann, 212 Minn. 233, 238, 240, 3 N.W.2d 226, 229, 230 (1942) (indicating that exculpatory clause stating “my said trustees shall not be liable for any *748mistake of judgment” did not protect the trustees from negligence); Fortune v. First Trust Co., 200 Minn. 367, 379, 274 N.W. 524, 530 (1937) (“[T]he distinction between negligence and mere errors of judgment must be borne in mind. ‘Trustees acting honestly, with ordinary prudence and within the limits of their trust, are not liable for mere errors of judgment.’”) (citation omitted). Moreover, this distinction has existed since before the trust instrument at issue here was created. Thus, we can reasonably assume that the trust creator was aware of these distinctions and could have exculpated a trustee for negligent acts had he wished to do so. Because our task is to find the intent of the trust’s creator, and trust instruments are to be strictly construed, we conclude that while the exculpatory clause protects a trustee from liability for “mistakes or errors of judgment,” it does not do so for negligent acts.
Norwest concedes that it is a professional trustee and has greater skills in the area of trusts than does a person of ordinary prudence. Therefore, Norwest was under a duty to use those skills under Minn.Stat. § 501B.10, subd. 1(a) (1994).2 Further, failure of a professional to meet a minimum standard of care is not a mere error in judgment. Wartnick v. Moss & Barnett, 490 N.W.2d 108, 116 (Minn.1992).
Generally, expert testimony is required to establish the standard of care and breach of that standard, unless the conduct can be evaluated by a jury in the absence of expert testimony. Id. A review of the record convinces us that a material fact issue exists as to whether Norwest met the minimum standard of care for a professional trustee. Appellant’s expert investment executive concluded in his affidavit that
[m]y professional experience indicates that even under special circumstances, the Borden holding should have represented no more than 10% of trust assets after a maximum of five years.
Moreover, the district court itself observed that “[appellant] raised substantial and serious questions as to whether Norwest breached its fiduciary obligations.” We must remand for trial on the issue of possible negligence of Norwest.
In determining the presence of a material fact issue on negligence, we of necessity reject Norwest’s reliance on Minnesota caselaw to support the argument that any error with respect to divesting the trust of Borden stock cannot be labeled negligence. In In re Will of Comstock, 219 Minn. 325, 17 N.W.2d 656 (1945) and Fortune, 200 Minn. at 367, 274 N.W. at 524, Minnesota courts determined that a trustee’s decisions concerning the disposition of trust securities involved only claimed errors of judgment, not negligence. Both Comstock and Fortune, however, were matters tried on their merits. The negligence issue went to a fact-finder. On appeal, the reviewing court merely concluded that the district court finding of no negligence was not incorrect as a matter of law. Fortune, 200 Minn. at 382, 274 N.W. at 531; Comstock, 219 Minn. at 333, 17 N.W.2d at 661. In remanding this matter, we are assuring that a decision will be made by the fact-finder after trial on the merits, consistent with the procedures in Comstock and Fortune.
III. Attorney fees
While remand for trial may obviate the necessity of addressing legal fees, we do so in the interest of fully analyzing issues that may recur. The determination of whether attorney fees will be chargeable to the trust is in the sound discretion of the district court. In re Trust Created by Boss, 487 N.W.2d 256, 262 (Minn.App.1992), review denied (Minn. Aug. 11, 1992). A trustee is entitled to reasonable attorney fees incurred in good faith in defending its administration of the trust, in defending a proceeding for the benefit of the trust, and in defending a beneficiary’s challenge to the trust’s administration. In re Trust Created by Hill, 499 N.W.2d 475, 494 (Minn.App.1993), review denied (Minn. July 15, 1993). However, where a trustee has acted in bad faith or has been *749guilty of fraud or inexcusable neglect that has caused loss to the estate, the trustee may be denied attorney fees. In re Trust of Freeman, 247 Minn. 50, 56, 75 N.W.2d 906, 910 (1956).
Norwest argues that the district court erred in denying attorney fees on the basis that “[appellant] raised substantial and serious questions as to whether Norwest breached its fiduciary obligations.” We find no merit in Norwest’s argument on this issue. Even without a judicial determination of misconduct, Minnesota permits courts to consider the underlying allegations against a trustee when deciding whether to allow the trustee’s attorney fees to be paid out of the corpus of the trust. See Kronzer v. First Nat’l Bank, 305 Minn. 415, 430, 235 N.W.2d 187, 196 (Minn.1975) (allowing the district court to use the underlying action as a reason to deny attorney fees even where the underlying action was not resolved).
Norwest also contends the district court abused its discretion by finding that Norwest’s litigation strategy was costly to the trust. Norwest admits, however, that it twice pursued writs of prohibition in connection with discovery requests, not in the interests of this particular litigation, but rather, because Norwest was concerned about the implications of these requests for other trusts in which Norwest is a corporate trustee. Moreover, the second writ of prohibition was denied by this court as “unauthorized and improper.” Also, Norwest refused to turn over the requested documents in a timely fashion. The district court did not err in citing Norwest’s litigation strategy in denying attorney fees.
Nor do we find merit in Norwest’s contention that its submission of a comprehensive exhibit list was not wasteful. While litigants should be allowed to argue their cases forcefully, presenting a list of 2,170 exhibits for a five-day trial appears excessive and wasteful, and the district court did not err in citing this as a basis for denying fees.
Next, Norwest claims that it reviewed certain tapes in order to find evidence of tampering, even though the tapes were for the most part transcribed. While Norwest may be correct to point out that such vigorous advocacy is not inherently problematic, the district court properly determined that. a trust should not have to pay for such advocacy that was this “zealous.”
We agree with Norwest that when the district court requested argument on attorney fees it did not make clear that it would only accept argument on Norwest’s attorney fees.3 Thus, it was not improper of Norwest to have briefed attorney fees issues with respect to appellant Williams’s attorney fees. We conclude that to the extent the district court denied reimbursement of attorney fees because of Norwest’s allegedly improper attorney fees arguments, the district court abused its discretion.
Finally, Norwest objects to any reliance by the district court, in denying fees, on Norwest’s timing in raising the exculpatory clause as a defense. The exculpatory clause was not raised as a defense by Norwest until a hearing on October 7, 1997 (one week before trial was initially set). Even at this hearing, it was counsel for Linstroth who first raised the issue of the exculpatory clause and its potential application to Nor-west. While Norwest may not have been required to raise the exculpatory clause as a defense early in the litigation, considerable litigation may have been avoided had it done so. Raising the exculpatory clause late in the litigation did not benefit the trust. The district court properly relied on this tardiness in denying fees.
IV. Future liability of Linstroth and Williams
Norwest contends the district court erred by discharging Linstroth and Williams from liability for their administration of the trust. The district court’s order concerning the liabilities of Linstroth and Williams appears to be somewhat contradictory. In its order and decree, the court stated:
2. That the contribution claims of Nor-west Bank Minnesota, National Association *750against Margaret L. Linstroth and Robert H. Williams be and hereby are dismissed without prejudice.
The “dismissed without prejudice” language indicates that Norwest is free to bring its contribution claim again in the future. See Black’s Law Dictionary 469 (6th ed.1990) (term meaning “dismissal without prejudice to the right of the- complainant to sue again on the same cause of action. The effect of the words ‘without prejudice’ is to prevent the decree of dismissal from operating as a bar to a subsequent suit.”). In another portion of the district court’s order, however, the court concluded that Linstroth and Williams would be “discharged and released from any and all liability for [their] administration of the trust.”
These conclusions appear to produce inconsistent rules of law.. By dismissing the contribution claim without prejudice, the court indicated an intention to allow a future claim. However, in stating that Williams and Lin-stroth were released from liability, the court may have precluded Norwest from effectively seeking contribution against Williams and Linstroth. Because the liability of Williams and Linstroth has not been litigated, we vacate the district court’s order to the extent that it releases Williams and Linstroth from liability for a future contribution claim by Norwest.
DECISION
Norwest may assert the exculpatory clause in the trust instrument as a defense to breach of trust without violating public policy. However, the district court erred in determining that the first portion of the exculpatory clause shields Norwest from liability. Further, the second portion of the clause does not protect Norwest from liability for negligent acts, and there is a fact issue as to whether Norwest was negligent. The district court correctly determined that certain attorney fees were not chargeable to the trust except in the case of attorney fees for argument with respect to Williams’ attorney fees. Finally, the district court’s order is vacated to the extent it releases Williams and Linstroth from liability for future contribution claims because these issues have not yet been litigated.
Affirmed in part, reversed in part, and remanded.
