OPINION
To collect outstanding legal fees, respondent law firm moved to establish and determine the amount' of an attorney lien under Minn.Stat. § 481.13 (2004). Appellants, former clients of respondent, argued that, because respondent forfeited the attorney fees by committing legal malpractice, a. lien cannot be established. The district court declined to consider appellants’ allegations of legal malpractice and breach of fiduciary duty in a summary proceeding and determined the amount of attorney fees incurred pursuant to the retainer agreement. .Appellants now contend that the district court erred in failing to consider their claims. . Appellants also move to supplement the record with a letter from respondent’s insurance carrier and to recover attorney fees for expenses incurred in drafting the motion. We affirm and .deny the motions.
FACTS
.In February 2003, appellants Scott and Bernadette Paulson •. (the Paulsons) retained respondent Thomas A. Foster & Associates,. LTD (Foster) to represent them in a construction-arbitration action against the builder of their residence. The parties entered into a retainer agreement, whereby the Paulsons agreed to pay Foster a $10,000 non-refundable retainer fee and 25 percent of any dollar amount recovered in the litigation.
*4 In May 2004, the Paulsons recovered $118,952 in settlement of their claims. Shortly thereafter, the Paulsons refused to pay Foster the attorney fees and costs contemplated in the retainer agreement, alleging that Foster committed legal malpractice and breached its fiduciary duty to them. On May 20, 2004, Foster served the Paulsons with notice of an attorney lien.
In June 2004, the construction company issued a check for the settlement amount payable to the Paulsons and Foster. Foster endorsed the check but requested that the Paulsons’ new counsel hold in trust the disputed attorney fees and costs.
Foster then brought a motion under Minn.Stat. § 481.13, subd. 1(c) (2004), to determine the amount of the attorney lien and enter judgment on the lien. At the hearing on the motion, the Paulsons argued that Foster forfeited its right to attorney fees and costs when, acting in bad faith, it failed to inform the Paulsons of an expert witness’s impeachable background and failed to convey settlement offers. In support of their claims, the Paulsons proffered two expert affidavits. The Paulsons requested that the district court either stay entry of judgment on the lien until the malpractice and fiduciary-duty claims were litigated or “declare that there has been a lawsuit, complete forfeiture [of] fees and [turn the money] over to Mr. and Mrs. Paulson.” Immediately following the hearing, the Paulsons served Foster with a complaint alleging malpractice, breach of fiduciary duty, breach of contract, and deceit and collusion.
The district court declined to order forfeiture of the fees or “declare that there ha[d] been a lawsuit” without a decision on the merits of the legal-malpractice claims. Instead, based on the terms of the retainer agreement, the district court entered judgment in favor of Foster for $30,204.56.
Aware of the Paulsons’ intent to sue Foster for legal malpractice, the district court ordered Foster to verify that its malpractice insurer would accept defense of the Paulsons’ malpractice claim before disbursing the fees. The district court received the requisite verification on October 26, 2004. Upon receiving the letter, the Paulsons moved to stay the entry of judgment pending further clarification as to whether Foster’s insurance would cover the non-malpractice claims in their complaint. The district court interpreted the Paulsons’ letter as a motion for reconsideration, which it denied. This appeal followed.
ISSUES
I. Did the district court err in establishing and determining the amount of an attorney lien without considering appellants’ professional-malpractice claims?
II. May appellants supplement the record with a letter from respondent’s insurer regarding coverage for appellants’ professional-malpractice claims?
III. May appellants recover attorney fees incurred in bringing the motion to supplement the record?
ANALYSIS
I.
Application of the attorney-lien statute is a question of law, which we review de novo.
Boline v. Doty,
*5 The Paulsons challenge the district court’s calculation of the amount of the attorney lien, arguing that Foster is not entitled to any attorney fees because it committed professional misconduct. Foster maintains that the district court properly awarded attorney fees based on the terms of the retainer agreement. The arguments here present a novel question, namely whether the district court is required to entertain a legal-malpractice defense in a summary proceeding to establish and determine the amount of an attorney lien.
A.
We first examine the nature of the attorney-lien proceeding under Minn. Stat. § 481.13 (2004). Derived from common law and later codified in statute, an attorney lien attaches to any recovery by the attorney in the course of representation.

Minn.Stat. § 481.13, subd. 1(a), (b);
Boline,
As an equitable lien, the attorney lien protects against a successful party receiving a judgment secured by an attorney’s services without paying for those services.
Johnson v. Blue Cross & Blue Shield of Minn.,
Minn.Stat; § 481.13 governs attorney liens and provides in relevant part:
(a) An attorney has a lien for compensation ... (1) upon the cause of action ... and (2) upon the interest of the attorney’s client in any money or property involved in or affected by any action or proceeding in which the attorney may have been employed....
(b) An attorney has a lien for compensation upon a judgment, whether there is a special express or implied agreement as to compensation, or whether a lien is claimed for the reasonable value of the services....
(c) A lien provided by paragraphs (a) and (b) may be established, and the amount of the lien may be determined, summarily by the court under this paragraph on the application of the lien claimant or of any person or party interested in the property subject to the lien.
Judgment shall be entered under the direction of the court, adjudging the amount due.
Minn.Stat. § 481.13, subd. 1. Subdivision 1 grants an attorney an inchoate lien on a recovery obtained through his or her efforts on behalf of a client. 7A C.J.S.
Attorney & Client
§ 450 (2004). The attorney may petition a district court to establish the lien, determine the proper

amount of the lien, and enter judgment accordingly.
N. States Power Co. v. Gas
Servs.
Inc.,
Minnesota caselaw has long characterized attorney-lien actions as summary proceedings.
See, e.g., Vill. of New Brighton v. Jamison,
The 2002 amendment to section 481.13 further clarified that an attorney-lien action will be conducted summarily regardless of the location and timing of the proceeding. 2002 Minn. Laws ch. 403, § 2;
N. States Power Co.,
B.
Having concluded that the establishment and enforcement of an attorney lien under Minn.Stat. § 481.13 are to be conducted summarily, we next consider whether a district court must entertain a legal-malpractice defense when calculating the amount of the lien. The term “summarily” means in a “summary proceeding.”
Vill. of New Brighton,
We have considered the appropriate balance between fairness and the summary nature of an attorney-lien proceeding. Although section 481.18 is silent as to permissible defenses in an action to establish and determine the amount of an attorney lien, we have held that due process requires that the procedure employed afford the parties a meaningful opportunity to be heard.
Id.; Gaughan,
Here, the district court declined to consider evidence that Foster breached its fiduciary duty and committed legal malpractice, reserving these issues for the pending malpractice suit. We agree with the Paulsons’ contention that Foster’s alleged misconduct may be relevant to calculating attorney fees.
Rice v. Perl,
To state a prima facie case for legal malpractice, a client must demonstrate (1) the existence of an attorney-client relationship; (2) acts constituting negligence or breach of contract; (3) that such acts were the proximate cause of the plaintiffs damages; and (4) that but for the malpractice defendant’s conduct, the malpractice plaintiff would have been successful in the prosecution or defense of the action.
Noske v. Friedberg,
The Paulsons rely on
Boline
and
Gaughan
to support their claim that the district court was required to consider the legal-malpractice defense. But this case differs significantly from the facts in
Bo-line
and
Gaughan.
In neither
Boline
nor
Gaughan
did the client raise a defense or counterclaim of professional misconduct, breach of fiduciary duty, or legal malpractice. Rather, the client contested the factual basis for calculating the amount of the fees. The
Boline
court reversed the amount of the attorney lien and remanded to permit the clients to litigate “their good-faith claim that the attorney’s fees were excessive.”
To litigate the Paulsons’ claims fully, the parties would need to offer expert witness testimony on complicated issues of causation and damage. Entertaining such claims in a proceeding under Minn.Stat. § 481.13 would impermissibly transform a summary-lien proceeding into a lengthy malpractice trial. Indeed, some questions fall beyond the scope of a summary proceeding.
See Fidelity & Deposit Co. v. Riopelle,
The plain language of the Minnesota attorney-lien statute, MinmStat. § 481.13, provides for a summary proceeding to establish and enforce a lien. Consideration of complex questions of professional negligence in the lien action is contrary to the legislative intent expressed in the language of the statute. Because neither section 481.13 nor Minnesota caselaw compels the district court to consider a breach-of-fiduciary-duty or legal-malpractice defense in an attorney-lien action, the district court did not err when it declined to entertain the legal-malpractice and breach-of-fiduciary-duty claims and instead determined the amount of the attorney lien based on the uncontested retainer agreement.

The Paulsons move to supplement the record with a letter from Foster’s malpractice insurer addressing the extent of Foster’s insurance coverage. The papers filed in the district court, the exhibits received in evidence, and the transcript of the proceedings, if any, shall constitute the record on appeal. Minn. R.

Civ.App. P. 110.01. An appellate court ordinarily may not consider matters outside the record.
Thiele v. Stich,
III.
The Paulsons also move pursuant to Minn. R. Civ.App. P. 139.06 for attorney fees incurred in filing their motion to supplement the record on the basis that Foster intentionally concealed the letter regarding insurance coverage. An appellate court may award attorney fees when the appeal is frivolous or in bad faith.
Brett v. Watts,
The record does not. demonstrate bad faith or intent to delay the proceedings. Moreover, the Paulsons are not entitled to attorney fees for preparing a motion to supplement the record with a document that is not pertinent to the issue on appeal.
DECISION
In a summary proceeding to establish and determine the amount of an attorney lien under Minn.Stat. § 481.13 (2004), the district court was not required to entertain defenses of legal malpractice and breach of fiduciary duty. The district court did not err in declining to entertain these claims in a summary attorney-lien proceeding.
Affirmed; motions denied.
