Attorney's Fees Clauses in Commercial Leases: The Complete 2026 Guide

Attorney's fees clauses are among the most consequential—and most overlooked—provisions in commercial leases. A poorly drafted or lopsided fees clause can transform a $12,000 rent dispute into an $85,000 war of attrition. A well-negotiated mutual fee-shifting provision, on the other hand, deters frivolous landlord actions and forces both sides toward early resolution.

Yet most commercial tenants sign leases without scrutinizing the fees clause at all. They assume litigation is unlikely, that the clause is boilerplate, or that they will never need to invoke it. That assumption is wrong. Commercial lease disputes are among the most common categories of business litigation in the United States, and the attorney's fees clause determines who bears the $40,000–$90,000 in legal costs that routine disputes generate. This guide gives you the framework, the math, the case law, and the model language to negotiate from strength.

The American Rule vs. the English Rule: How the Default Works

U.S. courts operate under the American rule: each party bears its own attorney's fees regardless of who prevails in litigation. This is the baseline in every jurisdiction absent a specific statutory or contractual override. The American rule has significant practical consequences—it means that even a clearly wronged party may rationally decline to pursue a small claim because the cost of litigation exceeds the recovery.

The English rule (fee-shifting) flips this: the losing party pays the winner's reasonable attorney's fees. England, most of Europe, and many arbitration regimes follow this model as the default. In the U.S., fee-shifting is available through: (1) specific statutes (e.g., federal civil rights laws, RICO, certain state consumer protection statutes); (2) court-imposed sanctions under Rule 11 or § 1927; and (3) contractual provisions—the mechanism that governs in commercial leases.

When a commercial lease contains an attorney's fees clause, the clause is treated as a contractual override of the American rule. Courts enforce these clauses as written (subject to state-specific limitations discussed below), which means the party that negotiated the better clause controls the litigation economics of the entire lease term.

Why This Matters for $12K Disputes

Consider a tenant withholding $12,000 in disputed CAM charges. Under the American rule, the landlord must weigh spending $40,000–$60,000 in attorney's fees to collect $12,000. Most rational landlords settle. Under a one-way English rule (landlord-only fees), the calculus shifts dramatically: the landlord knows it will recover fees if it wins, making even expensive litigation economically rational. The tenant, by contrast, faces $12,000 in rent exposure plus up to $85,000 in landlord's attorney's fees if it loses—a 7:1 risk multiple that generates enormous settlement pressure regardless of the merits.

One-Way vs. Mutual Fee-Shifting: The Core Distinction

Commercial lease attorney's fees clauses fall into three structural categories:

Prevailing Party Definitions: The Most Litigated Element

The definition of "prevailing party" determines who collects fees. Courts apply different tests depending on the lease language and the jurisdiction:

The Net Winner Test

The majority approach in most jurisdictions: whoever obtained the greater net monetary award (or achieved more of what they sought) is the prevailing party. Under this test, a landlord who sought $50,000 in unpaid rent but was awarded only $8,000 may still be the prevailing party if the tenant recovered nothing on its counterclaim. The net winner test can produce counterintuitive outcomes—a party that wins on the merits but is awarded minimal damages may end up with a reduced or denied fee award.

The Primary Issue Test

Several courts (particularly in New York commercial lease disputes) focus on which party prevailed on the most significant issue. If the central dispute was whether the landlord properly terminated the lease and the court holds the termination was improper, the tenant may be the prevailing party on attorney's fees even if it owes some back rent. The primary issue test rewards tenants who can isolate the key legal question and win it decisively.

California Statutory Prevailing Party (CCP § 1032)

California Code of Civil Procedure § 1032 defines prevailing party to include the party with a net monetary recovery, the defendant where judgment is entered against the plaintiff, and parties receiving costs under a voluntary dismissal. The statute interacts with Civil Code § 1717 to create a comprehensive framework: if neither party achieves a complete victory, the trial court has discretion to determine that there is no prevailing party and decline to award fees to either side.

Lease-Specific Definitions

The most sophisticated leases define "prevailing party" contractually. Strong tenant language reads: "For purposes of this Section, 'prevailing party' means the party that obtains the relief or recovery it sought, measured by the economic value of the judgment, award, or settlement compared to the position of each party as of the commencement of the action. A party that obtains a net recovery shall be deemed the prevailing party even if such recovery is less than the full amount claimed, unless the court or arbitrator exercises its discretion to find no prevailing party in light of the mixed nature of the result."

California Civil Code § 1717 and the Hana Financial Case

California's Civil Code § 1717 is the most important attorney's fees statute in U.S. commercial real estate. It provides that in any action on a contract that contains an attorney's fees clause, the prevailing party is entitled to fees regardless of which party the clause explicitly designates. The statute achieves two things:

1. Mutuality Conversion: A one-way clause designating only the landlord as fee-eligible becomes mutual—the tenant can recover fees if it prevails.
2. Discretionary No-Prevailing-Party Finding: Where the result is mixed (e.g., tenant wins on liability but landlord wins on damages), the court may find no prevailing party and deny fees entirely.

The Hana Financial line of California cases established that "prevailing party" status is determined based on achieving a "practical victory" on the central dispute—not just on which party received a favorable judgment label. In commercial lease litigation, this has been applied to hold that a tenant who successfully defended against eviction and obtained a court declaration that its lease was valid was the prevailing party entitled to fees—even though the landlord was awarded some unpaid rent as part of the same judgment.

Arbitration Clause Interaction: Fee Awards in Arbitration

The majority of commercial leases executed after 2015 contain mandatory arbitration clauses. The interaction between arbitration and attorney's fees provisions creates several issues that landlord forms routinely exploit and tenants routinely miss:

AAA Commercial Rules and Fee Awards

Under AAA Commercial Arbitration Rules (Rule 47(d)(ii)), the arbitrator may award attorney's fees only if authorized by applicable law or the agreement of the parties. If the lease contains an attorney's fees clause, the arbitrator is authorized to award fees. If the arbitration clause is silent on fees, the arbitrator may lack authority to award them even if the lease contract contains a fees clause—depending on how the arbitration clause is drafted relative to the fees clause.

The Scope Problem

Some landlord-form leases include attorney's fees clauses in the general provisions but include arbitration clauses that state: "The arbitrator's award shall be limited to direct damages; no attorney's fees or consequential damages shall be awarded." This effectively guts the attorney's fees clause for any dispute that goes to arbitration—which is most disputes under modern lease forms. Tenants should ensure the arbitration clause explicitly states: "The arbitrator shall have authority to award attorney's fees and costs to the prevailing party as provided in Section [X] of this Lease."

Preliminary Injunctions and TROs

If a party seeks emergency injunctive relief in court before invoking arbitration, attorney's fees incurred in the injunction proceeding may or may not be recoverable depending on whether the fees clause covers "all proceedings arising out of or relating to this Lease" or is narrowly limited to "arbitration." Tenants pursuing or defending emergency injunctions should confirm their fees clause applies to those proceedings before committing to expensive injunction litigation.

What "Reasonable" Attorney's Fees Means in Practice

Even when a party wins and is entitled to fees, the court or arbitrator must determine the "reasonable" fee amount. Courts use the lodestar method: multiply reasonable hours expended by the reasonable hourly rate for attorneys of similar experience in the same market. The lodestar can then be adjusted upward or downward based on factors including the result obtained, complexity of the case, and whether the prevailing party took unnecessary steps that inflated fees.

Market Hourly Rates (2026)

At New York partner rates, a 12-month commercial lease dispute involving contested summary judgment motions, depositions, and a 3-day bench trial can easily generate $120,000–$180,000 in billable hours. Under a one-way fees clause where the landlord prevails, those fees shift entirely to the tenant—on top of whatever the underlying judgment was.

Model Mutual Fee-Shifting Language

The following model language is designed to be fair to both parties, replace typical one-way landlord-form clauses, and survive challenge in most U.S. jurisdictions:

Fees in Bankruptcy Proceedings

When a commercial tenant files for bankruptcy protection, the automatic stay halts most landlord collection efforts—but the attorney's fees clause continues to govern fee obligations arising from the bankruptcy. Landlords often incur substantial fees seeking stay relief, objecting to tenant plans to assume or reject the lease, and litigating pre-petition rent claims in bankruptcy court. Whether these fees are recoverable depends on: (1) whether the fees clause expressly extends to bankruptcy proceedings; (2) whether the claim is treated as an administrative expense (entitled to priority) or a general unsecured claim; and (3) how the lease is ultimately treated (assumed, rejected, or renegotiated).

Tenants negotiating fees clauses should be aware that landlord forms frequently include language explicitly extending fee-shifting to bankruptcy proceedings. If the tenant ends up in financial distress, this provision can convert a standard proof of claim into an administrative priority claim for fees, jumping the queue ahead of other creditors.

Fees Clauses in Lease Renewals and Amendments

When a lease is amended, the attorney's fees clause in the original lease may or may not extend to disputes arising from the amendment. Courts are split: some hold that an amendment is a separate contract and requires its own fees clause; others treat the amendment as part of the original lease and apply the original fees clause. To avoid ambiguity:

• Every lease amendment should include a clause confirming whether the original lease's fees provision applies to disputes arising under the amendment.
• If the original lease has a one-way clause and you've negotiated a mutual amendment, confirm the amendment's mutual clause applies to the entire lease as amended.
• Exercise renewal options with a written acknowledgment that the renewed lease incorporates the fees clause.

Fees Clause Interaction with Indemnification Provisions

Many commercial leases contain both an attorney's fees clause and broad indemnification provisions. These can overlap in confusing ways. A tenant who is sued by a third party for injuries occurring in the premises, then seeks indemnification from the landlord, may find that the fees clause and the indemnification clause point to different outcomes: the fees clause may require the indemnified party to be the "prevailing party" to recover fees, while the indemnification clause may require the indemnitor to pay all costs including fees regardless of outcome.

Courts generally enforce the more specific provision. Tenants should ensure that indemnification provisions explicitly cover attorney's fees incurred in defending indemnified claims, separate from and in addition to the general prevailing party fees clause.

Negotiation Strategies by Tenant Type

Small Tenants (Under 5,000 SF)

Small tenants have the least leverage but the highest proportional risk from one-way fees clauses. A $15,000 dispute can generate $50,000 in landlord's fees—3.3× the underlying claim. Strategy: ask for deletion of the fees clause entirely (revert to the American rule) rather than arguing for mutuality. Landlords are more likely to agree to "no fees clause" than to mutual fee-shifting, as it protects them from an adverse judgment too. If the landlord insists on a fees clause, negotiate a dollar cap ($25,000–$50,000).

Mid-Size Tenants (5,000–25,000 SF)

Mid-size tenants have moderate leverage. Push for full mutual fee-shifting with a prevailing party definition that includes partial victories. Insist that the arbitration clause explicitly incorporates the fees provision. If you're in California, the statute already provides mutuality—but your attorney's fees clause language still determines what counts as "prevailing." If outside California, getting mutuality is the single most important improvement to a standard fees clause.

Large Tenants (25,000+ SF)

Large tenants with significant leverage should aim for: (1) mutual fee-shifting; (2) explicit extension to arbitration, appeals, and bankruptcy proceedings; (3) inclusion of expert witness fees and e-discovery costs in recoverable items; and (4) a provision that requires the landlord to provide quarterly fee estimates if it commences litigation, giving the tenant transparency on mounting exposure.

12-Item Attorney's Fees Clause Negotiation Checklist

• Identify whether the current clause is one-way (landlord only) or mutual — request mutual fee-shifting as baseline ask.
• Confirm whether your state has a mutuality statute (California § 1717, Florida § 57.105(7), Washington RCW 4.84.330) that already converts one-way clauses.
• Ensure the "prevailing party" definition covers partial victories and settlements, not just final judgments.
• Verify the fees clause extends to arbitration proceedings and that the arbitration clause expressly authorizes fee awards.
• Confirm the fees clause covers appeals, post-judgment enforcement, and bankruptcy proceedings.
• Check whether the clause limits recovery to "reasonable" fees actually incurred and paid (avoids inflated in-house rate awards).
• Include paralegal fees, expert witness fees, and e-discovery costs within the definition of recoverable fees.
• Negotiate a cap on fee recovery if you are a smaller tenant — a $50,000 mutual cap is better than an unlimited one-way clause.
• Confirm the fees clause applies to counterclaims, cross-claims, and third-party actions, not just the primary claim.
• Review the interaction between the fees clause and indemnification provisions — avoid gaps where indemnified claims fall outside both provisions.
• In lease amendments and renewals, explicitly confirm whether the original fees clause applies or whether the amendment controls.
• If the lease is governed by California law regardless of your state, ensure your counsel reviews Civil Code § 1717 implications on any fees clause you sign.
