¶ 1. LOUIS B. BUTLER, JR., J.

Anthony and Naomi Anderson ("Anderson") seek review of an unpublished court of appeals decision that concluded the circuit court properly exercised its discretion by awarding Accident Fund Insurance Company nearly $7,500 in attorney fees and costs as part of the reasonable costs of collection in a third-party settlement distribution under Wis. Stat. § 102.29(1) (2001-02). Anderson v. MSI Preferred Ins. Co., No. 2003AP1880, unpublished slip op. (Wis.Ct.App. Feb. 10, 2004). Anderson argues this court should reverse the court of appeals' decision on either of two grounds: (1) conclude that for a worker's compensation carrier's attorney to join in the pressing of the claim against the third-party tortfeasor requires the attorney to demonstrate that his or her activities substantially contributed to obtaining recovery from the third party; or (2) agree that Accident Fund's failure to produce any evidence of hours worked and rate charged requires overturning the circuit court's exercise of discretion.

¶ 2. We decline Anderson's invitation to alter the existing law for what is required to join in the pressing of a claim against a third party. In short, because the worker's compensation carrier has the same right to bring, and an equal voice in prosecuting, a third-party claim, and because the worker's compensation carrier's attorney does not represent the employee, the attorney is entitled to recover reasonable attorney fees and costs associated with representing the worker's compensation carrier as part of the reasonable costs of collection under Wis. Stat. § 102.29(1).

¶ 3. However, we conclude that the circuit court erroneously exercised its discretion by failing to determine whether $17,700 in total fees and costs on a $25,000 settlement constitutes the reasonable costs of collection in this case. Therefore, we reverse the court of appeals' decision and remand this matter to the circuit court for a hearing to determine what the reasonable costs of collection are and how those costs are to be apportioned between the attorneys.

¶ 4. On October 15, 2001, Anderson was injured in a motor vehicle accident caused by Shawn Jones. It is undisputed that Anderson was in the course of his employment at the time of the accident and that his injuries arose out of his employment. Jones was insured by Acceptance Insurance Co. and had a policy limit of $25,000. Accident Fund paid worker's compensation benefits and medical expenses totaling $8,711.98.

¶ 5. In March 2002, Accident Fund referred the case to Walther Law Offices, SC, to seek reimbursement for the payments it made to Anderson. See Wis. Stat. § 102.29(1). On July 11, 2002, Accident Fund directed Walther to take an active role in managing the claim to protect its reimbursement interest.

¶ 6. On July 23, 2002, Anderson commenced a third-party tort action against Jones, Acceptance Insurance Co., and MSI Preferred Insurance Co. (Jones' underinsured motorist carrier), pursuant to Wis. Stat. § 102.29(1). However, Anderson did not name Accident Fund as a party, even though § 102.29(1) gives both the employee and the worker's compensation carrier the same right to make the third-party claim and requires each to "give to the other reasonable notice and opportunity to join in the making of such claim. . . ."

¶ 7. In August 2002, Accident Fund began searching for Jones' insurer. After learning Jones' insurer was Acceptance Insurance, Accident Fund also learned that Anderson commenced a Wis. Stat. § 102.29(1) claim. Concerned with whether Anderson would protect its interests, Accident Fund prepared a motion to intervene, but Anderson voluntarily joined Accident Fund as a party on October 9, 2002.

¶ 8. The claim against Jones was mediated on March 3, 2003, and Acceptance Insurance Co. offered its policy limits of $25,000. The parties did not resolve the distribution of the proceeds under Wis. Stat. § 102.29(1).

¶ 9. Just over one month later, on April 17, Anderson filed a motion to approve the settlement and distribution of the proceeds. The motion listed Accident Funds' costs of collection as $3,547.13, a figure Anderson received from Accident Fund a month earlier during the mediation. Accident Fund opposed the distribution, asking that the court award it $7,472.97 in costs of collection. The parties filed briefs in support of their positions. On May 20, the Barron County Circuit Court, Honorable James C. Babler, approved the $25,000 settlement but set a hearing for a determination on the distribution of the proceeds. The court required the parties to submit affidavits and any other necessary documents to support their fees and costs.

¶ 10. Anderson submitted an affidavit that stated Accident Fund indicated its costs of collection were only $3,547.13 at the mediation. Anderson also attached a copy of the attorney's contingency fee agreement, which provided for a one-third recovery plus out-of-pocket expenses. The affidavit expressed Anderson's belief that its contingency fee was reasonable and then generally listed the activities taken in pursuing this claim.

¶ 11. Accident Fund also submitted an affidavit. It contested Anderson's assertion regarding its costs of collection, claiming that it never suggested its costs were actually $3,547.13. Accident Fund stated that that amount was a settlement offer to resolve its costs of collection, an offer Anderson rejected. Accident Fund further stated that the mediation and settlement occurred as a result of its persistence on having, and its argument during, mediation. As was the case with Anderson's affidavit, Accident Fund's submissions cursorily describe the legal work done and did not contain the numbers of hours worked or the fee charged. Accident Fund did not include an itemized billing of costs.

¶ 12. At the hearing on June 26, Anderson claimed it was unreasonable for Accident Fund to claim an additional $3,000 in fees that were apparently incurred from the mediation to the filing of the affidavits. Anderson took issue with Accident Funds' failure to supply the court with any proof regarding the number of hours billed, an itemization of what work was done, when it was done, and the hourly rate at which it was done. Finally, Anderson argued that it was unreasonable for Accident Fund to claim over $7,000 as costs of collection to secure an $8,711.98 reimbursement interest.

¶ 13. Accident Fund reiterated that it simply offered to settle the fees and costs at the mediation for $3,547.13, a figure that represented the fees and costs incurred prior to attending the mediation session. Although Accident Fund knew that there could be additional costs associated with attending the mediation, it stated it was willing to compromise and not claim those additional amounts. From the close of the mediation to the date of the hearing, Accident Fund averred it now had incurred $7,472.97 in total fees and costs.

¶ 14. Accident Fund further explained that some of its fees were incurred because Anderson did not provide it with notice of the suit as required by Wis. Stat. § 102.29(1). Accident Fund indicated it was suspicious of Anderson following this failure and did not trust him to protect its interest. What those fees and costs were, however, was not developed.

¶ 15. The circuit court found that Anderson's failure to join Accident Fund from the beginning was not intentional or based on bad faith, but did result in Accident Fund becoming distrustful of Anderson and how the case was to be handled. The court then concluded it was required to approve Accident Fund's fees of $7,472.97. The court expressed regret at having to do so, but stated the high costs were associated with Anderson's handling of the case from the beginning.

¶ 16. Anderson appealed, arguing that the court erred by concluding it was required to award Accident Fund's fees and costs, as opposed to awarding the reasonable costs of collection, and that there was an insufficient factual basis to sustain that award. The court of appeals affirmed. The court noted that the circuit court requested affidavits detailing the basis for each party's costs and read the affidavits at least three times. Anderson, No. 2003AP1880, unpublished slip op., ¶ 12.

¶ 17. Because the circuit court indicated it read the affidavits multiple times, the court of appeals concluded that the circuit court implicitly based its decision on them. Id., ¶ 18. The court of appeals then turned to the relevant factors in SCR 20:1.5(a) and evaluated them in light of the record. Id., ¶¶ 19-24. The court concluded the record revealed a rational basis for the circuit court's conclusion that Accident Fund's fees were reasonable. Id., ¶ 24. Therefore, the court concluded the award was not the product of an erroneous exercise of discretion. Id. We accepted Anderson's petition for review, and we reverse.

¶ 18. This case requires us to interpret Wis. Stat. § 102.29(1). Statutory interpretation presents a question of law we review de novo. German v. DOT, 2000 WI 62, ¶ 7, 235 Wis. 2d 576, 612 N.W.2d 50. Our goal is to discern the intent of the legislature. Id. The purpose of statutory interpretation is to determine what a statute means so that it may be given its full, proper, and intended effect. State ex rel. Kalal v. Circuit Court for Dane County, 2004 WI 58, ¶ 44, 271 Wis. 2d 633, 681 N.W.2d 110. We begin with the statute's language because we assume that the legislature's intent is expressed within the words it used. Id., ¶ 45. Generally, language is given its common, ordinary, and accepted meaning. Id. If the statute's meaning is plain, we ordinarily stop the inquiry. Id.

¶ 19. Our review of the circuit court's value of reasonable attorney fees and costs is limited to whether the circuit court properly exercised its discretion. See Meyer v. Michigan Mut. Ins. Co., 2000 WI App 53, ¶ 11, 233 Wis. 2d 493, 609 N.W.2d 167. A proper exercise of discretion requires the circuit court to employ "a logical rationale based on the appropriate legal principles and facts of record." Id. (citation and quotation omitted). As this court recently recognized, "We give deference to the circuit court's decision because the circuit court is familiar with local billing norms and will likely have witnessed first-hand the quality of the service rendered by counsel." Kolupar v. Wilde Pontiac Cadillac, Inc., 2004 WI 112, ¶ 22, 275 Wis. 2d 1, 683 N.W.2d 58. We will uphold the circuit court's determination unless it erroneously exercised its discretion. Id. "If the circuit court proceeds on an erroneous interpretation of the law, the exercise of discretion is erroneous." Theis v. Midwest Sec. Ins. Co., 2000 WI 15, ¶ 8, 232 Wis. 2d 749, 606 N.W.2d 162.

III

¶ 20. Wisconsin Stat. § 102.29(1) "was enacted to direct the courts in the distribution of proceeds of third-party tort actions." Nelson v. Rothering, 174 Wis. 2d 296, 303, 496 N.W.2d 87 (1993). The division of settlement proceeds under § 102.29(1) is legislatively mandated and may be deviated from only with the consent of both parties. Id. at 303-04. The proceeds recovered on any third-party tort claim are distributed as follows:

After deducting the reasonable cost of collection, one-third of the remainder shall in any event be paid to the injured employee or the employee's personal representative or other person entitled to bring action. Out of the balance remaining, the employer, insurance carrier or, if applicable, uninsured employers fund shall be reimbursed for all payments made by it, or which it may be obligated to make in the future, under this chapter, except that it shall not be reimbursed for any payments of increased compensation made or to be made under s. 102.18 (1) (bp), 102.22, 102.35 (3), 102.57 or 102.60. Any balance remaining shall be paid to the employee or the employee's personal representative or other person entitled to bring action. . . . If both the employee or the employee's personal representative or other person entitled to bring action, and the employer, compensation insurer or department, join in the pressing of said claim and are represented by counsel, the attorneys' fees allowed as a part of the costs of collection shall be, unless otherwise agreed upon, divided between such attorneys as directed by the court or by the department. § 102.29(1). Thus, the reasonable costs of collection are first deducted from any recovery. These costs include both the employee's and the worker's compensation carrier's attorneys' fees and costs if both attorneys "join in the pressing" of the claim. Id.

¶ 21. Anderson argues that to join in the pressing of the claim requires the worker's compensation carrier to demonstrate that its attorney's activities substantially contributed to making the third party pay. He asserts that the worker's compensation carrier should not recover reasonable attorney fees for activities that merely duplicate the activities of the injured party's attorney, or merely document the amount of its lien interest, and are not effective or necessary in procuring a recovery from the third party.

¶ 22. In advancing this argument, Anderson recognizes that the court of appeals held to the contrary in Zentgraf v. The Hanover Insurance Co., 2002 WI App 13, ¶ 14, 250 Wis. 2d 281, 640 N.W.2d 171. Because we agree with and adopt that reasoning, we see no reason to depart from that precedent.

A

¶ 23. We begin with Wis. Stat. § 102.29(1). That section recognizes an employee's right to maintain a tort claim against a third party who caused the underlying worker's compensation injury, but it gives worker's compensation carriers "the same right." Perhaps most importantly, § 102.29(1) explains that both the employee and the worker's compensation carrier "shall have an equal voice in the prosecution of said claim. . . ."

¶ 24. If both the employee and the worker's compensation carrier "join in the pressing" of the third-party tort claim and "are represented by counsel, the attorneys' fees allowed as a part of the costs of collection shall be, unless otherwise agreed upon, divided between such attorneys as directed by the court or by the department." Id.

B

¶ 25. This court first considered what it meant to join in the pressing of the claim in Diedrick v. Hartford Accident Indemnity Co., 62 Wis. 2d 759, 216 N.W.2d 193 (1974). In Diedrick, this court affirmed that Wis. Stat. § 102.29(1) contemplates but one "reasonable cost of collection" if both the employee and the worker's compensation carrier "join in the pressing" of the third-party claim. Diedrick, 62 Wis. 2d at 766-67. Finding § 102.29(1) plain and unambiguous, this court stated, "[t]he statute specifically requires the court approving the settlement to determine the attorneys' fees to be allowed where both the injured party and the compensation carrier joined in bringing the claim to court, and then requires the trial court to divide the fees allowed `between such attorneys.'" Id. at 763-64 (citations omitted).

¶ 26. In bringing a claim to court, the Diedrick court recognized that the services the worker's compensation carrier's attorney performed are recoverable even if not completed "at the request of or on behalf of the employee." Id. at 767. This court determined that the statute allows the worker's compensation carrier's attorneys to recover a "reasonable fee based on services performed for and on behalf of the carrier." Id. "[I]t is immaterial," this court concluded, "whether efforts of the carrier's counsel contributed to the employee's recovery." Id. at 766. Examples of those efforts that were recoverable included the carrier's counsel drafting required legal papers, handling the advance depositions, and participating in the negotiations for settlement. Id. at 767.

¶ 27. The court of appeals expanded on what it means to press the claim against the third party in Zentgraf, 250 Wis. 2d 281. Following a third-party settlement approval, American, the worker's compensation carrier, argued the circuit court erred by not awarding it its attorney fees as a cost of collection under Wis. Stat. § 102.29(1). Zentgraf, the employee, argued that none of American's activities constituted legal efforts "to prepare the case for trial or to reach a settlement." Id., ¶ 15. Zentgraf contended that absent active participation in the pressing of the principal third-party claim, which he claimed was contributing services toward the successful result, American was not entitled to attorney fees as part of the reasonable cost of collection. Id. The court of appeals disagreed.

¶ 28. The court of appeals turned to ordinary dictionary definitions of "press" to understand what it means to join in the pressing of the claim. Id., ¶ 18. The court observed that press meant "to follow through (a course of action)," "to seek to influence, as by insistent arguments; entreat insistently," and "to attempt to force to action; urge on." Id. (citations and quotations omitted). Under any of these definitions, the court concluded, American joined in the pressing of the claim against the third party. As examples of American's pressing activities, the court offered:

In addition to repeatedly notifying the circuit court of the amount of its lien claim and its intent to participate in the prosecution of the claim against Duame [the third party tortfeasor] and his insurer, counsel for American: (1) was in frequent contact with attorneys for the other parties; (2) responded to requests from both defense counsel and plaintiffs' counsel to produce documents; (3) requested, received, and reviewed medical records from multiple medical institutions; (4) spent time preparing for the final pretrial conference; (5) frequently reviewed the case file to determine the status of discovery and investigation; (6) prepared for and attended a mediation conference; (7) analyzed Wis. Stat. § 102.29 implications for settlement and repeatedly communicated with the Zentgrafs' attorney regarding distribution of the settlement proceeds; (8) prepared a motion to postpone the hearing on the Zentgrafs' motion to approve the settlement and distribution of its proceeds as outlined in their proposed order; (9) prepared a letter brief and affidavit with supporting documentation; and (10) prepared for and attended the motion hearing. Although the Zentgrafs emphasize that the action was settled in April 2000, substantial issues regarding distribution of the settlement funds remained until the circuit court signed the Zentgrafs' proposed order on January 11, 2001.

Id., ¶ 19. Ultimately, the court of appeals remanded the case for further proceedings to determine the attorney fees due. Id., ¶ 20.

¶ 29. We see no reason to supplant the interpretations given to Wis. Stat. § 102.29(1) in Diedrick and Zentgraf with Anderson's substantial contribution test. Both decisions are consistent with Wis. Stat. § 102.29(1)'s grant that both the injured employee and the worker's compensation carrier have "the same right" to maintain the third-party claim and "an equal voice in the prosecution of said claim." Both decisions also recognize that the attorneys represent different parties, which may have unaligned interests. Thus, any activities that the attorney takes to bring the claim to court on behalf of his or her client, as expanded in Zentgraf, constitute a cost of collection amenable to recovery under § 102.29(1).

¶ 30. To conclude that a worker's compensation carrier cannot recover attorney fees for work that "merely duplicate[s]" the employee's attorney's actions or "simply document the amount of the lien" ignores that this work is performed on behalf of the client, the worker's compensation carrier. As Zentgraf illustrated, there can be a laundry list of activities undertaken as part of normal advocacy in bringing a claim to court that has little to do with "substantially contributing to making the third-party pay." Therefore, we will not depart § 102.29(1)'s prior precedent.

IV

¶ 31. Anderson's second argument is that Accident Fund failed to establish the reasonableness of its claimed costs of collection. In particular, Anderson notes that Accident Fund did not file proof of the hours worked, the rate billed, or an itemization of disbursements.

¶ 32. Accident Fund responds by criticizing Anderson for the same shortcomings. Although Anderson's fee was based on a one-third contingency fee agreement, Accident Fund notes that Anderson has provided no basis upon which to conclude that his fee and costs were reasonable. On this issue, we agree with both parties.

¶ 33. As mentioned above, Wis. Stat. § 102.29(1) contemplates a deduction for costs of collection, and that deduction must be reasonable. Diedrick, 62 Wis. 2d at 766-67. In this case, the circuit court awarded $17,730.12 as the reasonable cost of collection on a $25,000 settlement; $10,257.15 to Anderson's attorney ($8,333.33 one-third contingent fee and $1,923.82 in costs), and $7,472.97 to Accident Fund for attorney fees and costs.

¶ 34. While the award of attorney fees is a matter left to the circuit court's discretion and is entitled to deference, the circuit court in this case did not consider the reasonableness of the aggregate fees and costs, let alone the reasonableness of the individual fees in the first instance. Instead, the circuit court concluded that it was required to approve Accident Fund's attorney fees. This was an erroneous interpretation of the law, and thus an erroneous exercise of discretion. See Theis, 232 Wis. 2d 749, ¶ 8. Considering the lack of information the circuit court had to work from, our review of the record cannot salvage the circuit court's order.

¶ 35. On remand, the circuit court must first determine what constitutes the reasonable cost of collection. Although seemingly simple, this task is complicated here since Anderson's attorney is working on a contingency fee basis while Accident Fund is working on an hourly basis. To determine what the reasonable cost of collection is, the circuit court will have to manage alternate tests to gauge the reasonableness of the different attorney fees, while bearing in mind that the aggregate of reasonable attorneys' fees may not result in a reasonable cost of collection. We discuss each test in turn.

A

¶ 36. In Meyer, the court of appeals was confronted with whether the circuit court properly exercised its discretion by awarding an employee's attorney a one-third contingent fee (resulting in a $333,333.33 fee) as part of the reasonable cost of collection under Wis. Stat. § 102.29(1). Meyer, 233 Wis. 2d 493, ¶¶ 1, 9. For guidance, the court of appeals turned to Village of Shorewood v. Steinberg, 174 Wis. 2d 191, 204, 496 N.W.2d 57 (1993), an eminent domain case involving awarding attorneys' fees. The court of appeals noted that in Village of Shorewood, this court determined that a contingency fee agreement was to be used only as a guide when calculating reasonable attorney fees; it is not controlling. Meyer, 233 Wis. 2d 493, ¶ 13. The court of appeals further observed that the Village of Shorewood court held that the circuit court must consider all of the circumstances to determine whether a contingency fee figure is reasonable and looked to the factors in SCR 20:1.5(a) to help steer that determination. Meyer, 233 Wis. 2d 493, ¶ 13. Using that framework, the court of appeals determined that the circuit court properly exercised its discretion by awarding the employee's attorney a one-third contingency fee. Id., ¶ 23.

¶ 37. As in Meyer, the circuit court in this case must evaluate Anderson's one-third contingency fee in light of all the circumstances. The court must not simply enforce the contingency fee agreement. Supreme Court Rule 20:1.5(a) lists factors that help determine the reasonableness of an attorney's fee, which are:

(1) the time and labor required, the novelty and difficulty of the questions involved, and the skill requisite to perform the legal service properly;

(2) the likelihood, if apparent to the client, that the acceptance of the particular employment will preclude other employment by the lawyer;

(3) the fee customarily charged in the locality for similar legal services;

(4) the amount involved and the results obtained;

(5) the time limitations imposed by the client or by the circumstances;

(6) the nature and length of the professional relationship with the client;

(7) the experience, reputation, and ability of the lawyer or lawyers performing the services; and

(8) whether the fee is fixed or contingent.

Id. Although each factor need not be examined, the circuit court must consider "all the circumstances of the case to determine whether the contingency fee amount is a just and reasonable figure." Village of Shorewood, 174 Wis. 2d at 204.

¶ 38. We pause to note that we do not question the propriety of a contingency fee in a third-party tort claim. We recognize that contingency fees play a vital role in ensuring that certain claimants get access to the courts by providing attorneys with a sufficient incentive that outweighs the risks of litigating uncertain claims. We further recognize that contingent fees also counterbalance prior gambles the attorney took that returned little or nothing in terms of compensation. Nevertheless, assessing the reasonableness of Anderson's contingency fee is necessary here as it is the first step in determining the reasonable costs of collection under Wis. Stat. § 102.29(1). See infra Part IV.C.

B

¶ 39. Scrutinizing Accident Fund's attorney fees requires a different analysis because Accident Fund's attorney is working on an hourly basis. To determine the reasonableness of Accident Fund's attorney's fees, all parties concede that the circuit court must follow this court's recent decision in Kolupar, 275 Wis. 2d 1. In Kolupar, this court adopted the lodestar approach for determining reasonable attorney fees in fee-shifting statutes. Under this analysis, the circuit court must first multiply the reasonable hours expended by a reasonable rate. Id., ¶ 29. The circuit court may then make adjustments using the SCR 20:1.5(a) factors. Id., ¶¶ 29-30.

C

¶ 40. After determining the reasonable value for each party's fees and costs, the circuit court's inquiry does not end. Wisconsin Stat. § 102.29(1) requires deducting the reasonable cost of collection from third-party claim proceeds. The sum of the attorneys' reasonable fees and costs may, but need not, equal a reasonable cost of collection. The circuit court must evaluate the total cost of collection and determine whether that sum is reasonable, in light of, among other things, the recovery. SCR 20:1.5(a)(4).

¶ 41. As in evaluating the reasonableness of the contingency fee and hourly fee, the circuit court has wide discretion here. Examples of factors to consider as highlighted in this case include the quality and quantity of services provided (to weed out costs and fees that are merely duplicative, needless, or unreasonable with regard to pressing the claim), the amount recovered from the third party, and the posture of the case (to take into account whether additional litigation was necessitated by the lack of notice and the need for appellate litigation. See Pagel v. Kees, 23 Wis. 2d 462, 472, 127 N.W.2d 816 (1964)).

¶ 42. And finally, after determining the reasonable costs of collection, the court must direct, unless otherwise agreed, how the attorneys' fees are to be divided between the attorneys.

V

¶ 43. To foreclose an issue that will arise on remand, we address a question that emerged during oral argument. On November 16, 2003, Anderson arbitrated his underinsured motorist (UIM) claim and he received $85,000, with a $25,000 reduction for the prior settlement. Accident Fund contends that the circuit court's determination of what constitutes reasonable costs of collection should take into account the UIM claim proceeds, as it suggests that much (if not all) of the groundwork for the UIM claim was laid during the third-party tort claim.

¶ 44. We cannot reconcile Accident Fund's contention with Wis. Stat. § 102.29(1). That section specifically deals with third-party liability, specifically "an action in tort against any other party for such injury or death." Id. The worker's compensation carrier has "the same right to make claim or maintain an action in tort against any other party for such injury or death." Id. Out of the proceeds of "said claim," the worker's compensation carrier is entitled to the reasonable costs of collection. A UIM claim, however, is not a third-party tort claim. As is an uninsured motorist claim, a UIM claim is a first-party contract claim. See Berna-Mork v. Jones, 174 Wis. 2d 645, 651, 498 N.W.2d 221 (1993) ("[U]nder sec. 102.29(1), Stats., an employer or compensation insurer has no right to subrogation against uninsured motorist benefits available to the employee because an action for uninsured motorist benefits is based on contract not tort."); Danner v. Auto-Owners Ins., 2001 WI 90, ¶ 51, 245 Wis. 2d 49, 629 N.W.2d 159 ("Underinsured motorist coverage provides first party coverage that affords compensation for injured persons whenever a tortfeasor is inadequately insured." (citation and quotation omitted)). Thus, we see no basis upon which to conclude that the worker's compensation carrier obtains the benefit of having its fees and costs artificially enlarged by inflating the recovery the injured employee ultimately obtains.

VI

¶ 45. In sum, we conclude that Wis. Stat. § 102.29(1) does not require a worker's compensation attorney to demonstrate that his or her activities substantially contributed to obtaining recovery from the third party, or that the activities were taken on behalf of the employee, in order to join in the pressing of a claim. However, the cost of collection must be reasonable. Because the circuit court did not consider whether the total costs of collection in this case were reasonable in light of the amount recovered, and because the court lacked sufficient information upon which to base its determination regarding attorneys' fees, we reverse the court of appeals' decision and remand the matter to the circuit court for a determination of what the reasonable costs of collection are and how those costs are to be apportioned between the attorneys.

By the Court. — Reversed and cause remanded for further proceedings consistent with this opinion.
