The primary issue we confront in this case is whether a settlement by a lessor of a personal injury action by an employee of the lessee based solely on allegations of the lessor’s own negligence precludes recovery in a subsequent action by the lessor for contractual indemnification against the lessee. We conclude the settlement precludes indemnification under the facts of this case. We affirm the order by the district court granting summary judgment.
I. Background Facts and Proceedings.
The facts of this case date back to 1994 when Neumann-Kiewit Constructors, Inc. (Neumann), a joint venture formed by Neumann Brothers, Inc. and Kiewit Construction Company for the purpose of constructing the Employers Mutual Casualty Insurance Company building in downtown Des Moines, leased a 150-ton crawler crane from McNally & Nimergood (McNally). McNally is a Michigan corporation, and Neumann needed the crane to assist in the construction of the building. The lease was a “bare rental,” which meant the crane was leased without an operator.
The terms of the lease were developed by the parties through an exchange of their respective form agreements. McNally initiated the process when it sent Neu-mann its form lease agreement. The lease required Neumann to pay McNally $6000 a month for the use of the crane, and covered a twelve-month period. McNally was authorized to adjust the monthly payments if Neumann did not need the crane for the full twelve months. The agreement also included the following provisions:
C. ... Lessee shall be responsible for normal maintenance and for repair of any damage incurred....
*568 D. INSURANCE AND LIABILITY OF LEASEE: ... Lessee assumes full responsibility for and indemnifies Lessor against and will protect and save Lessor against harm from any and all loss, liability, damage, and expense in connection with any injury or claim of injury of Lessee’s employees and will save Lessor harmless from any and all loss, liability, damage, and expense to other persons or any property arising from or in connection with the use or operation of the leased equipment....
The McNally lease agreement was dated August 25, 1994. It was signed by an authorized representative of McNally.
After receiving the McNally lease agreement, Neumann sent McNally its own form rental agreement. Like the McNally lease, the lease rate was $6000 a month, but the term was designated to be between ten and twelve months, with no adjustments in the monthly rate. The rental agreement also included the following provisions:
[B.] (iii) DAMAGES. Lessee shall be liable for any and all damage to any persons or property while said equipment is in Lessee’s possession, except for damage caused by defects in the equipment.

G. ATTORNEY’S FEES. In the event either party institutes suit in court against the other party in connection with any dispute or matter arising under this Agreement, the prevailing party shall be entitled to recover a reasonable attorney’s fee in addition to any other relief granted by the court.
H. FULL AGREEMENT. The agreement constitutes the full and complete understanding between the parties ....
The agreement also required Neumann to inspect and examine and replace or repair the crane if not found in good condition. It further required Neumann to keep the crane in good repair. '
The unsigned rental agreement included a one-page attachment containing additional provisions. These documents were sent with a cover letter to McNally stating, “Enclosed is our rental agreement and attachments.” The letter requested McNally to “sign both the rental agreement and attachments and return them to us for final execution.” The lease agreement was also enclosed with the letter. It contained several handwritten changes made by Neumann. Like the rental agreement, the lease agreement was not signed by Neumann.
An authorized representative of McNally signed the rental agreement and returned the documents to Neumann. An authorized representative of Neumann then signed the rental agreement. Neumann, however, did not sign the lease agreement.
The crane was subsequently delivered by McNally to the construction site of the Employers’ Mutual Insurance Company building in Des Moines. On November 28, 1994, William Lawson, Jr., an employee of Neumann, was seriously injured while erecting a tower crane needed to construct the building. The accident occurred when Lawson’s arm was pinched between an erected section of the tower crane and another section of the tower crane that was being hoisted into place with the crawler crane.
Lawson brought an action against Neu-mann and McNally for the injuries he sustained. He claimed Neumann was negligent in failing to inspect the crawler crane, failing to maintain and service the crane, and failing to properly operate the crane. Lawson claimed McNally was negligent in failing to inspect the crawler crane prior to its delivery, failing to properly maintain the crane prior to its delivery, and delivering a crane with a defective pump.
*569 However, McNally asserted as an affirmative defense that Neumann was negligent and that the negligence of Neumann was a superceding cause of Lawson’s injury. The district court subsequently dismissed the action against Neumann. It determined that recovery against Neu-mann was limited to workers’ compensation benefits. The case proceeded to trial against McNally.
After four days of trial, Lawson and McNally settled the claim for $499,000. The settlement agreement released McNally from liability, but did not release Neumann. No liability was admitted by McNally and McNally did not give up any subsequent remedies.
Following the settlement, McNally made repeated demands on Neumann for indemnification under the lease agreement. After Neumann declined to reimburse McNally for the settlement, McNally filed an action against Neumann for indemnification. The petition was filed on August 25,1998.
McNally claimed both the rental agreement and the lease agreement combined to form the terms of the parties’ complete agreement, which included the duty of Neumann to provide indemnification. McNally claimed indemnification was also provided under the damage clause in the rental agreement based on the language that made Neumann “liable for any and all damage to any persons or property while said equipment is in Lessee’s possession, except for damage caused by defects in the equipment.” It claimed indemnification was required by the lease agreement under the “INSURANCE AND LIABILITY OF LESSEE” clause providing that Neu-mann assume “full responsibility for and indemnifies Lessor against and will protect and save Lessor against harm from any and all loss, liability, damage, and expense in connection with any injury or claim of injury of Lessee’s employees.” In addition to the expressed contractual obligations for indemnification, McNally claimed the duties under both agreements requiring Neumann to inspect, maintain and repair the crane also formed the basis for implied indemnification.
On October 12, 1999, Neumann moved for summary judgment. It asserted the agreement between the parties was limited to the terms of the signed rental agreement, which excluded indemnification for damages caused by defects in the equipment and was not broad enough to require indemnification for McNally’s own acts of negligence.
The district court granted summary judgment. It found the parties’ agreement was confined to the rental agreement under the integration clause. It determined this agreement did not provide for indemnification for McNally’s own negligence. The district court also awarded Neumann attorney fees for defending the indemnification claim of $77,828.50.
McNally appeals. It claims summary judgment was improper because a factual dispute exists over the scope of the parties’ written agreement. Additionally, McNally asserts that it does not seek indemnification for liability based on its own negligence or for any defect in the crane which existed prior to delivery, but seeks indemnification based on the breach of Neu-mann’s contractual promise to indemnify it for Neumann’s own acts of negligence. McNally claims both the expressed and implied contracts require Neumann to indemnify it for the settlement it paid to Lawson as long as it can show Neumann was negligent and that Neumann’s negligence was a cause of the injury. McNally argues that it is entitled to a trial to make this showing. It also argues the trial court abused its discretion in awarding the amount of attorney fees to Neumann for defending the action.

IV.Express Contract for Indemnification.
Under a contract for indemnification, “one party (the
indemnitor)
promises to hold another party (the
indemni-tee
) harmless for loss or damage of some kind....” II E. Allan Farnsworth,
Farns-worth on Contracts
§ 6.3, at 108 (2d ed.1998). The indemnitor “promises to indemnify ... [the] indemnitee against liability of [the] indemnitee to a third person, or against loss resulting from [the] liability.” 42 C.J.S.
Indemnity §
2, at 72 (1991). Generally, no particular language is required to support indemnification, and a written agreement can be established without specifically expressing the obligation as indemnification.
See Jenckes v. Rice,
A contract for indemnification is generally subject to the same rules of formation, validity and construction as other contracts.
Evans v. Howard R. Green Co.,
This principle of construction must be considered in this case because the legal claims for damages paid by McNally in settlement were based solely on the allegations of its own negligence. Neumann claims our strict rule of construction does not allow the contract to be interpreted to require it to indemnify McNally for its own negligence.
For purposes of summary adjudication, we will consider the indemnification clauses in both the lease agreement and the rental agreement together. The lease agreement was broad and all-inclusive. It provided for indemnification for all damage claims “arising from or in connection with the use or operation of the [crane].” The rental agreement also broadly encompassed liability for all damage “while [the crane was] in [the] Lessee’s possession,” but specifically excluded “damage caused by defects in the equipment.”
Since the time we first recognized our rule of construction against indemnification for the indemnitee’s own negligence unless the intention to do so is clearly and unequivocally expressed, we have tended to apply the rule by distinguishing contracts permitting indemnification for the indem-nitee’s own negligence from those that do not by looking for specific language in the contract addressing the fault or negligence of the indemnitee.
See Employers Mut. Cas. Co. v. Chicago & N.W. Transp. Co.,
However, the distinction between contracts that explicitly mention the indemnitee’s own fault or negligence and those that do not was never intended to create a fixed limitation on our rule of construction. We have long recognized that indemnity contracts do not need to expressly state that the indemnitee will be indemnified for its own negligence if the clear intent of the contractual language provides for such indemnification.
See Weik v. Ace Rents Inc.,
Nevertheless, the rental agreement specifically addressed the issue of causation by excluding indemnification for “damage[s] caused by defects in the equipment.” Thus, even if the broad lease provisions were construed to provide for indemnification without regard to fault, the language in the rental agreement, which both parties agree was part *573 of the contract, expressed the clear intention of the parties that Neumann would have no obligation to indemnify McNally if damage was the result of a defect in the crane. This specific clause trumps the general clause. The only purpose of this exclusion would be to express the intent for Neumann to be responsible for all damages, regardless of the cause, except those damages relating to a defect in the crane. Thus, the contract entered into by the parties expressed a clear intent for McNally to be indemnified for its own negligence, unless that negligence was based on or attributable to a defect in the crane. The defect exclusion would also apply to any negligence of McNally that was responsible for the existence of a defect, such as the failure to inspect the crane for defects prior to its delivery and a failure to maintain the crane free from defects prior to its delivery. In such instances, the defect remains the ultimate cause of the injury and makes the failure to inspect and maintain actionable.
Consequently, it is not important to our analysis to decide whether the indemnification clause was limited to the terms of the rental agreement or also included the terms of the lease agreement. Even assuming the district court improperly limited the contract to the terms of the rental agreement, the additional terms of the lease agreement do not impact the analysis. The parties contracted for indemnity under both agreements, but not. in the event the damage resulted from a defect in the crane.
V. Implied Contractual Indemnification.
McNally further claims there is an implied contract for indemnity based on the duties imposed on Neumann in the lease and rental agreements to maintain the crane in good condition and to notify McNally in the event the crane is not in good condition. McNally asserts the breach of these contractual duties by Neu-mann forms a basis for indemnification for the settlement amount paid to Lawson in this case.
Like other contracts, a contract for indemnification can be expressed or implied. It can be implied when the parties have entered into a contract that imposes an independent duty that implies a mutual intent to indemnify for liability or loss resulting from a breach of the duty.
See Johnson v. Interstate Power Co.,
In this case, both the lease agreement and the rental agreement imposed inde-péndent duties on Neumann to maintain the crane in good condition, and the rental agreement additionally required Neumann to notify McNally of any damage to the crane. Considering the nature of the agreement, these are the types of duties that we have recognized can give rise to an implied obligation to indemnify for a loss. See id.
Notwithstanding, even if indemnification is implied by virtue of an independent duty imposed on Neumann under the lease or rental agreement, the terms of the implied agreement for indemnification would not include indemnification for the indemnitee’s own negligence, such as a defect in the crane. Consistent with the rule of construction for expressed con
*574
tracts, there can be no indemnification based on the indemnitee’s own negligence absent a clear intent.
See Herter,
VI. Settlement of Underlying Claim.
McNally argues that it does not seek indemnification based on any damages resulting from a defect in the crane. Instead, it argues that it has evidence to establish that the damages sustained by Lawson resulted from Neumann’s negligence in failing to properly maintain and operate the crane, which makes Neumann responsible for indemnification under the expressed agreement as well as its theory of implied indemnification. McNally asserts it is entitled to a trial to establish Neumann’s negligence and its responsibility for indemnification.
Before beginning our analysis of this claim, we acknowledge the complexity of the law of indemnification and the challenges that can confront judges and lawyers in its application to particular factual circumstances.
See Woodruff Constr. Co.,
This case gives rise to two important and related concepts of indemnification. The first principle is that a party who seeks to establish a right to indemnity in an independent action must normally plead and prove it was liable to the injured party.
Ke-Wash Co. v. Stauffer Chem. Co.,
The requirement to plead and prove liability established in
Ke-Wash
applies in independent actions for indemnity where the underlying claim for damages was settled without an adjudication of liability.
Ke-Wash Co.,
The importance in this case of the rule that requires the indemnitee to be liable for the damages is brought to life by Neu-mann’s argument that proof by McNally that it was liable for the loss or damage will defeat the claim for indemnity because the duty to indemnify under both claims for indemnification asserted by McNally does not cover liability or loss attributable to a defect in the crane or McNally’s conduct relating to the defect. McNally responds that the rule requiring proof of liability is inapplicable to its claims of expressed or implied contractual indemnification and does not apply to claims for indemnity based solely upon Neumann’s own negligence.
We specifically indicated in
Ke-Wash
that the need for the indemnitee to prove its liability to the injured party does not apply “where there is an expressed agreement for indemnification providing otherwise.”
Id.
However, this exclusion was not intended as a blanket limitation for all claims based on expressed indemnification, but exists to recognize that express indemnification agreements can alter the common law rules on indemnity by calling for indemnification in the absence of underlying liability between the indemnitee and the injured party.
See
42 C.J.S.
Indemnity
§ 23(b), at 112 (rule that indemnity does not protect the indemnitee against loss through voluntary payments may be affected by the terms of the indemnification agreement). We specifically recognized this type of exclusion in
Ke-Wash,
where we cited
Robert & Company Associates v. Pinkerton & Laws Co.,
Thus, the express indemnification exception recognizes that contract law can alter the common law concepts of indemnification, and impose obligations not otherwise supported by those equitable principles that drive noncontractual indemnification. On the other hand, if an expressed agreement does not reveal an intent to alter the rule against voluntary payment, the fundamental rule of liability for loss to the injured party applies, and the claim for indemnity must be viewed in its traditional form as shifting liability for a loss from one person who is legally responsible to another person.
We have previously determined in this case that the only limitation placed in the indemnification agreement was liability or loss based on a defect in the crane. However, there is no further indication the parties intended to alter the concept of indemnification by . imposing a duty on Neumann to reimburse McNally in the *576 event McNally paid for the damages to an injured person when it was not liable to the injured person for the damages.
Alternatively, McNally argues that the Ke-Wash rule against voluntary payments is a product of tort-based indemnification and was never intended to apply to implied contractual claims for indemnification, such as those claimed in this case. Thus, McNally argues that the rule in Ke-Wash does not apply to claims for implied indemnification based on the breach of independent duty arising from a contract. 2
We agree with McNally that the rule against voluntary payment established in
Ke-Wash
arose from a tort-based claim for indemnity.
See Ke-Wash Co.,
We think the apparent conflict is resolved by recognizing that the implied indemnification adopted in Woodruff is not a broad concept. Instead, it is viewed as a remedy in those situations in which a breach of a duty imposed under a contract between the two parties caused injury to a third party for which the nonbreaching party was not primarily liable, but only secondarily liable. See id. at 785-86. We, of course, recognize indemnity based on vicarious or derivative liability in a tort setting, but a separate remedy is necessary when the source of the duty arises from a contract instead of tort and equitable principles. Thus, while the concept of shifting responsibility for loss from one who is secondarily liable to one who is primarily liable remains the same, the different source of the duty requires different theories of recovery.
Accordingly, we discern no inconsistency between the general rule against *577 voluntary payments recognized in Ke-Wash and the rule limiting the implied indemnification concept recognized in Woodruff to indemnitees who did not aid in creating the hazard. An indemnitee can be liable to the injured party by operation of legal principles, yet not actually contribute to the hazard which caused the injury. In truth, we would create an inconsistency in our law if we adopted McNally’s argument. We conclude the rule expressed in Ke-Wash applies to McNally’s claim for implied indemnification asserted in this case.
The second rule that comes into play in this case is that a claim for contractual indemnity must be covered by the contract.
See Ke-Wash Co.,
We have previously determined that the indemnification agreement in this case does not alter the requirement for McNally to show that it was liable to the injured party. Yet, the only limitation upon the shifting of liability from McNally to Neumann was that the injury resulted from a defect in the crane. In that situation, Neumann had no duty to indemnify McNally because it was not covered in the agreement. Conversely, any other circumstances were covered. Thus, to recover under the agreement, McNally would only be required to show its liability is not based upon a defect in the crane prior to delivery. If McNally was liable for other reasons, including Neumann’s negligence, Neumann would have a duty to indemnify under the contract.
Generally, issues of liability presented in an indemnification action are not suitable for summary adjudication without a prior judicial determination of the issues. When an indemnitee settles the underlying action for damages, a subsequent action for indemnification normally requires a judicial determination of the issues raised in the case. However, the need for a hearing will ultimately depend upon the terms of the indemnification agreement and the scope of the allegations of the underlying claim by the injured party.
In this case, the underlying claim that gave rise to McNally’s liability or loss was restricted to allegations of McNally’s own negligence. Moreover, those allegations of negligence were not covered under the indemnification contract. The indemnification contract specifically excluded liability based on defect. Thus, any liability that could have been imposed on McNally in the underlying action could only have been based on a de-
*578
feet in the crane, which was a noncovered claim. Therefore, it is not enough that Neumann may have been negligent and that its negligence was covered under the agreement. Instead, McNally must show the loss it suffered or the liability it incurred was covered. Neumann’s negligence could not have been the basis for McNally’s liability under the allegations of the underlying action, and an indemnitee cannot transform the underlying claim by the injured party into a different lawsuit by making allegations of negligence against the indemnitor in a subsequent action for indemnity. When the underlying litigation settled by a potential indem-nitee was limited to allegations of the in-demnitee’s own negligence not covered under the indemnification agreement, there can be no claim for indemnity because the amount paid in the settlement could only have been the result of the indemnitee’s own noncovered negligence.
See Olin Corp. v. Yeargin Inc.,
We emphasize that the settlement of the underlying case by an indemnitee does not always constitute a waiver of the right to seek indemnification.
See Liberty Mut. Ins. Co.,
VII. Attorney Fees.
Finally, we address McNally’s contention that the district court abused its discretion in setting the amount of attorney fees for Neumann in defending the action. The contract for indemnification in this case permitted Neumann to obtain reasonable attorney fees to compensate for the costs expended in defending the action for indemnification brought by McNally. Neumann initially requested $90,466.76 in attorney fees and $11,544.32 in additional expenditures. In exercising its discretion, the district court reduced the attorney-fee claim to $77,828.50 and rejected the claim for other expenses. Because we find the district court acted within its discretion in setting the amount of attorney fees to Neumann, we affirm the award of attorney fees by the district court.
VIII. Conclusion.
We conclude the settlement by an in-demnitee of an underlying claim for damages based solely on the negligence of the indemnitee precludes indemnification under a contract that does not cover loss based on the indemnitee’s own negligence. The district court properly granted summary judgment.
AFFIRMED.
Notes
. Tort-based indemnity has been recognized in Iowa under four circumstances. They are: vicarious liability, liability based on conduct directed by the indemnitor, liability based on the breach of an independent duly of care owed by the indemnitor, and liability based on the failure of the indemnitor to discover or prevent misconduct.
Hansen,
. We have previously indicated that indemnification implied from the breach of an independent duty expressed in a contract is in the nature of a contract implied by law.
