OPINION
MATTHEWS, Justice.I. INTRODUCTION
Federal statute 25 U.S.C. § 410 (1994) insulates from the reach of creditors proceeds from the sale or lease of Indian allotment lands. A road which became public was illegally built on Bertha Mae Tabbytite’s allotment. More than two decades later, the land on which the road was located was formally taken in condemnation proceedings and a money judgment in her favor was entered. The main question in this case is whether the proceeds from this judgment are protected under section 410. We answer in the affirmative because we conclude that the judgment is money accruing from an involuntary lease and sale of Tabbytite’s land.
II. FACTS AND PROCEEDINGS
Bertha Mae Tabbytite owns a 160-acre Indian allotment in the Chugach Mountains in Anchorage. In 1958 Glen Clarke constructed a road across Tabbytite’s property without any right to do so. Clarke transferred the road to the City of Glen Alps. Glen Alps was eventually annexed by the Municipality of Anchorage.
Litigation prompted by the road began in 1969 when the United States, joined by Tab-bytite as an intervener, sued to enjoin the use of the road and sought trespass damages. The course of the litigation can be traced through United States v. Clarke, 529 F.2d 984 (9th Cir.1976); United States v. Clarke, 590 F.2d 765 (9th Cir.1979); and United States v. Clarke, 445 U.S. 253, 100 S.Ct. 1127, 63 L.Ed.2d 373 (1980). In the case last cited, *1145the Supreme Court of the United States held that the Municipality could not acquire the road by inverse condemnation.
The Municipality then brought a formal condemnation action to acquire the road. Ten years after it was filed, the case was tried in the United States District Court for the District of Alaska. The court awarded Tabbytite damages of $165,962, consisting of four items:
(1) Value of the property on which the road is constructed — $13,162;
(2) Value of the road as constructed (separate from the value of the bare land) — ■ $60,000;
(3) Fair rental value of the bare land on which the road is built from the date of first Municipal occupancy until condemnation — $13,000; and
(4) Fair rental value of the road as constructed (separate from the rental value of the bare land) — $79,800.
Both the Municipality and Tabbytite appealed from the condemnation award. The Ninth Circuit rejected the arguments of both parties and affirmed the award on September 23,1992.
Between 1976 and 1980, Vincent Vitale acted as counsel to Tabbytite in connection with the litigation described above. In 1980 Tab-bytite terminated the lawyer-client relationship. Prior to his termination, Vitale filed an attorney’s lien seeking security for payment of his fees from litigation proceeds. After the Ninth Circuit affirmed the condemnation award, the Municipality owed Tabbytite, including interest and less sums previously deposited, $197,460. The Municipality did not believe that it could deliver this sum to Tab-bytite without risking double liability because it was aware of Vitale’s lien claim. It therefore filed a complaint for interpleader in the superior court against Tabbytite and Vitale. Alleging that it had no interest in the funds but that it was exposed to possible double liability, the Municipality requested the adjudication of the validity of the conflicting claims of Tabbytite and Vitale.
Vitale answered the interpleader complaint and asserted a cross-claim against Tabbytite, seeking enforcement of his attorney’s lien. Tabbytite responded by filing a fee arbitration petition under Alaska Bar Rule 39. Tabbytite petitioned to stay the interpleader action under the automatic stay provisions of Alaska Bar Rule 39(b). The superior court granted this petition. Thereupon the focus of the parties shifted to the fee arbitration.1
The fee arbitration panel reached its decision on March 15, 1995. It awarded Vitale $64,375, representing the present value of fair and reasonable compensation for his services to Tabbytite. Vitale then moved in the interpleader action for an “Order Confirming and Reducing to Judgment” the arbitration award and for a final judgment and disbursement of the interpled funds.
Tabbytite opposed this motion and moved for dismissal of the action. One ground which she asserted in her opposition and in support of her motion to dismiss was based on 25 U.S.C. § 410, which provides as follows:
No money accruing from any lease or sale of lands held in trust by the United States for any Indian shall become hable for the payment of any debt of, or claim against, such Indian contracted or arising during such trust period, or, in case of a minor, during his minority, except with the approval and consent of the Secretary of Interior.
After much additional briefing, the superi- or court entered an order dismissing the case, reasoning that it was divested of subject matter jurisdiction by the application of 25 U.S.C. § 410. Finding that the condemned land was held in trust on dates pertinent to section 410, the court wrote:
[T]his court concludes that a condemnation is a sale, albeit a forced one. See Jackson v. New York, [213 N.Y. 34,] 106 N.E. 758 (N.Y.1914), in which Justice Cardozo said: “ ‘[condemnation’ is an enforced sale, and the state stands toward the owner as a *1146buyer toward a seller.” But, if there be any doubt on the issue, the doubt should be resolved in favor of defendant Tabbytite under the well recognized principle that when a statute affecting Indian rights is ambiguous the ambiguities must be resolved in favor of the Indian. Bryan v. Itasca County, 426 U.S. 373, 392[, 96 S.Ct. 2102, 2112-13, 48 L.Ed.2d 710] (1976). Finally, this Court’s determination that condemnation proceeds are protected by 25 U.S.C. 410 furthers the intent of the statute which is to protect revenue generated by Indian trust land. Squire v. Capoeman, 351 U.S. 1[, 76 S.Ct. 611, 100 L.Ed. 883] (1956).
The court dismissed the action and ordered the interpled funds returned to the Municipality of Anchorage. Subsequently, Tabby-tite moved for attorney’s fees and costs. This motion was denied for the stated reason that the court lacked subject matter jurisdiction over the underlying dispute.
Vitale appeals. On appeal he raises essentially three arguments. First, he argues that he was entitled to a personal judgment against Tabbytite based on the arbitration award. Second, he contends that section 410 did not divest the superior court of jurisdiction. And third, he argues that section 410, for a number of reasons, does not apply to the interpled funds.
Tabbytite has filed a cross-appeal from the court’s failure to award her attorney’s fees and costs. We proceed to address the parties’ arguments.
III. DISCUSSION
1. Was Vitale Entitled to a Personal Judgment Based on the Fee Arbitration Award?
We answer this question in the affirmative. Bar Rule 40(t) requires the superior court to confirm an award and reduce it to judgment upon the application of a party unless either party has timely sought to vacate, correct or modify it.2 Tabbytite advances two grounds in opposition.
First, she claims that 25 U.S.C. § 82 (1994) prohibits Vitale from enforcing any personal contract with Tabbytite without approval of the Secretary of the Interior.3 Section 82 applies to agreements “made by any person with any tribe of Indians, or individual Indians not citizens of the United States....” 25 U.S.C. § 81 (1994). The application of section 82 to individual Indians currently has little, if any, force, since it is limited to Indians who are not citizens of the United States. Tabbytite makes no claim that she is not a United States citizen, and therefore she is not entitled to the protection of section 82.
Second, Tabbytite presents an argument the caption of which states: “The Findings of the Panel Are Based on Fraud.” The entire argument presented under this caption is as follows:
Ms. Tabbytite asserts that the findings of the Fee Arbitration Panel are based on incorrect information. Ms. Tabbytite asserts that Mr. Vitale waived any fee when he voluntarily withdrew from the underly*1147ing federal case cited above. She has been consistent and persistent on that point. Furthermore she is insistent that Mr. Vi-tale’s claims are not recognizable in State Court. Ms. Tabbytite respectfully requests this Court to affirm the dismissal.
Under AS 09.43.120(a) an arbitration award can be vacated if it was procured by fraud.
Tabbytite’s argument in her brief on appeal is an almost verbatim reproduction of the argument she made in opposition to the motion to confirm the award before the trial court. No instance of fraud is specified in this argument. Fraud, in fact, is not mentioned. Fraud, even in an initial pleading, must be averred with particularity. Alaska R. Civ. P. 9(b). It follows that a confirmation award may not be resisted merely by reciting without specificity that fraud existed. Further, at the motion stage, evidentiary support for particular fraud claims must be presented. See, e.g., Alaska R. Civ. P. 56(c); McHugh v. Church, 583 P.2d 210, 217 (Alaska 1978). We conclude therefore that Tabbytite did not present a legally sufficient claim of fraud as a defense to the motion to confirm. Further, given her briefing as set forth above, if she had presented such a defense it would be waived on appeal because of inadequate briefing. See Adamson v. University of Alaska, 819 P.2d 886, 889 n. 3 (Alaska 1991); State v. O’Neill Investigations, Inc., 609 P.2d 520, 528 (Alaska 1980).
2. Did the Superior Court Have Subject Matter Jurisdiction ?
We answer this argument in the affirmative as well. Even if 25 U.S.C. § 410 bars imposing liability on the proceeds of the condemnation action, nothing in section 410 excludes state court jurisdiction. Section 410 does not purport to make federal jurisdiction exclusive. Where a federal statute is silent on the question of jurisdiction, state and federal courts have concurrent jurisdiction. Charles Dowd Box Co. v. Courtney, 368 U.S. 502, 506-08, 82 S.Ct. 519, 522-23, 7 L.Ed.2d 483 (1962); Paul v. Nauska, 395 P.2d 260, 262-63 (Alaska 1964). Indeed, a state court of general jurisdiction may not refuse to hear a case brought under a federal statute unless it also lacks jurisdiction to hear state cases of the same type. Testa v. Katt, 330 U.S. 386, 67 S.Ct. 810, 91 L.Ed. 967 (1947); E.A. v. State, 623 P.2d 1210, 1215 n. 13 (Alaska 1981). Thus the superior court had jurisdiction to decide the application of section 410 to the proceeds in question here.
Because we hold that the superior court had jurisdiction, we need not address Vitale’s arguments regarding various permutations of the doctrine of res judicata. Similarly, his arguments that Tabbytite waived her jurisdictional objections are mooted.
3. Does Section 110 Apply to the Proceeds of the Condemnation Case?
We answer this question in the affirmative for the reasons expressed by the superior court.4 Section 410 is designed to exempt certain Indian property from liability for the payment of certain debts. In Matter of City of Nome, 780 P.2d 363, 367 (Alaska 1989), we noted that a federal statute designed to protect from creditors certain categories of Indian property should be construed broadly: “ambiguities must be resolved in favor of the Indians.” Id.
An award of compensation for land which is forcibly conveyed in a condemnation action can readily be categorized as money accruing from a sale of the land in question. As Judge Cardozo put it, “ ‘Condemnation’ is an enforced sale, and the state stands toward the owner as buyer toward seller. On that basis the rights and duties of each must be determined.” Jackson v. State, 213 N.Y. 34, 106 N.E. 758, 758 (1914); see also, United States v. 27,223.21 Acres of Land, 589 F.Supp. 1121, 1124 (D.Colo.1984); Herskovitz v. Vespico, 238 Pa.Super. 529, 362 A.2d 394, 397 (1976).
Similarly, damages for the precondemnation use of land are analogous to lease proceeds. The court in the condemnation case calculated damages for the precondemnation use of Tabbytite’s land based on its fair rental value:
*1148The fair rental value of the road, from the time the City began its occupancy, to the time the City condemned the road, was $13,000. This compensates Ms. Tabbytite for the fair market value of the City’s use during the time that the City did not pay rent for the land upon which the road was built. This is the rent value of the bare land, not including the improvement.
The City had the advantage of the improved road, which had been conferred as an unwanted benefit by Clarke onto Tab-bytite’s land, for nineteen years, from 1961 to 1980. The fair rental value of the bare land during this time must be increased by the rental value of the improvement. I find that a fair measure, roughly in accord with market values, for a lease of the improvement subject to maintenance by the Municipality as tenant, would be 7% per year of what it cost to build the road, $60,000, times 19 years, for a rent on the improvement of $79,800. This is for rent value of the improvement, independently of the rent value of the bare land.
(Emphasis added.) Just as Tabbytite can be said to have involuntarily sold a portion of her land and received proceeds for the sale in the condemnation action, it is reasonable to conclude that the use of the same land prior to the formal condemnation action was an involuntary leasing and the damages for that use were lease accruals.
Vitale argues that trespass damages are not the equivalent of proceeds from a forced lease. He points out that damages for trespass may include amounts for emotional distress suffered by the owner and for physical harm to the land and that such amounts would not take on the character of lease proceeds. We need not decide whether trespass damages are equivalent to lease proceeds in every case. In this case there is no doubt that the entire amount of the damage award for trespass was based on the precon-demnation use of the land measured by its rental value. The award thus had the character of lease proceeds. See Restatement (Second) of Torts § 931 cmt. b & illus. 1 (1979).
We conclude, for the above reasons, that all of the proceeds from the condemnation action reasonably can be considered to have accrued from the lease or sale of allotment lands. The proceeds thus fall within the protection of section 410.5
Vitale contends that, even if the proceeds here are protected by section 410, attorney’s fees arising from work performed to protect allotment rights are excepted from the section’s bar. As support for this position he cites Arenas v. Preston, 181 F.2d 62 (9th Cir.), cert. denied, 340 U.S. 819, 71 S.Ct. 50, 95 L.Ed. 602 (1950).
In Arenas, the Ninth Circuit allowed an attorney’s lien to be placed on an Indian allotment despite the inalienability of that land. Id. at 66-67. In doing so the court reasoned that such a course of action would, in effect, serve the congressional purpose of affording extra protection to Native allotments. Id. at 66. That is, without the services of the attorney the Indian would not have received his allotment at all. Id. Vitale urges this court to apply this same doctrine to proceeds protected by section 410.
While the matter is not free from doubt, we think that Arenas is not controlling. Section 410 is neither mentioned nor discussed in the Arenas opinion. Given that section 410 applies, we are not free to decide this case based on the rationale underlying Arenas, because that rationale conflicts with the explicit command of the statute.6
*11494. Did the Trial Court Err in its Denial of Attorney’s Fees?
Tabbytite argues on cross-appeal that the superior court should have awarded her attorney’s fees under Civil Rule 82 because she was the “prevailing party.” The superior court declined to award attorney’s fees because it had ruled that it possessed no subject matter jurisdiction. Because we hold that the superior court had jurisdiction, we also direct that court to consider the issue of attorney’s fees on remand. The superior court must, of course, determine who is the prevailing party before awarding fees.
TV. CONCLUSION
The dismissal of this case for lack of subject matter jurisdiction is REVERSED. This ease is REMANDED for (1) entry of a personal judgment in favor of Vitale, (2) entry of judgment awarding the interpled funds to Tabbytite, (3) determination of the prevailing party and an award of attorney’s fees to such party, and (4) such other and further relief as may be appropriate.
RABINOWITZ, J., with whom COMPTON, C.J., joins, dissents.
. This was interrupted by Tabbytite’s subsequent removal of the interpleader to federal court. The United States District Court for the District of Alaska remanded the case to the state superior court on motion of Vitale, which was not opposed by Tabbytite. The court stated: "It appears that removal was not timely and that it is doubtful that any federal question exists.”
. Bar Rule 40(t) provides:
Confirmation of an Award. Upon application of a parly, and in accordance with the provisions of AS 09.43.110 and AS 09.43.140, the superior court will confirm an award, reducing it to a judgment, unless within ninety days either party seeks through the superior court to vacate, modify or correct the award in accordance with the provisions of AS 09.43.120 through 140.
. 25 U.S.C. § 82 provides:
Payments under contracts; aiding in making prohibited contracts. No money shall be paid to any agent or attorney by an officer of the United States under any such contract or agreement, other than the fees due him for services rendered thereunder; but the moneys due the tribe, Indian, or Indians, as the case may be, shall be paid by the United States, through its own officers or agents, to the party or parties entitled thereto; and no money or thing shall be paid to any person for services under such contract or agreement, until such person shall have first filed with the Commissioner of Indian Affairs, a sworn statement, showing each particular act of service under the contract, giving date and fact in detail, and the Secretary of the Interior and Commissioner of Indian Affairs shall determine therefrom whether, in their judgment, such contract or agreement has been complied with or fulfilled; if so, the same may be paid, and, if not, it shall be paid in proportion to the services rendered under the contract.
. Vitale does not argue that Tabbytite’s land is not land held in trust by the United States for any Indian; thus we assume that Tabbytile's land is within the coverage of section 410.
. Vitale’s argument regarding the fact that, at the time his services were rendered, there had been no sale or lease of the land in question and that, therefore, section 410 is inapplicable, is without merit. Section 410 proceeds are exempt from all claims arising during the period the land is held in trust, regardless of the relationship in time between the accrual of the claim and the sale or lease. Vitale’s argument that applying section 410 unconstitutionally impairs his contract rights is also without merit. It is inconceivable that the inability to levy on a specific fund to satisfy a debt unconstitutionally impairs a contract underlying the debt when the bar on levying pre-exists the making of the contract. Vitale's ex post facto argument is similarly misguided. Section 410 was enacted in 1906. See 25 U.S.C. § 410. He rendered his services seventy years later.
. Further, textual adherence to section 410 does not necessarily mean that indigent allotment holders cannot obtain effective representation. At least in some circumstances, as the facts in this case illustrate in part, the Department of *1149Justice provides representation to allotment holders. Moreover, we cannot assume that the Secretary of the Interior will unreasonably disapprove of reasonable fees under section 410.
