Browsewrap Arbitration Clauses Are Unenforceable Under Maryland Law When Unilateral “Change-in-Terms” Takes Effect Upon Site Visit Without Advance Notice

Introduction

In Kaitlyn Trimble v. Entrata, Inc. (4th Cir. Aug. 11, 2026), the Fourth Circuit affirmed a district court’s refusal to compel arbitration in a putative class action challenging “convenience fees” charged through Entrata’s online rent-payment portal (“ResidentPortal”). The plaintiff, Kaitlyn Trimble, alleged Entrata acted as an unlicensed collection agency and sought to recover convenience fees under several Maryland consumer and debt-collection statutes (including the Maryland Collection Agency Licensing Act and Maryland Consumer Debt Collection Act), as well as equitable and tort theories.

The dispositive issue on appeal was not the merits of the fee claims, but whether a valid arbitration agreement existed under Maryland contract law. Entrata relied on an arbitration provision embedded in hyperlinked Terms and Conditions presented on the rent-payment page. The Fourth Circuit held the arbitration agreement unenforceable for lack of consideration because Entrata’s promise to arbitrate was illusory: Entrata reserved the unilateral ability to change the Terms from time to time, with no meaningful advance notice and no opportunity for users to end the contract before changes took effect.

Summary of the Opinion

The FAA favors enforcing arbitration clauses, but the pro-arbitration presumption does not apply to the threshold question whether a valid arbitration agreement was formed.
Maryland law requires consideration for an arbitration agreement; a mutual promise to arbitrate can supply that consideration.
A promise is not consideration if it is illusory—i.e., the promisor can escape the obligation at will.
Entrata’s “Change Clause,” coupled with its “Notices Clause,” allowed Entrata to modify the Terms (including arbitration) without providing users meaningful advance notice and without giving users a chance to end the agreement before changes became binding.
Entrata’s argument that changes only became effective when a user returned to the site failed because the Terms bound users immediately upon visiting; users could not receive notice or review changes without being automatically bound.
The court also rejected Entrata’s framing of each portal transaction as a separate, stand-alone contract; the Terms contemplated an ongoing service relationship.
Result: no agreement to arbitrate was formed; denial of the motion to compel arbitration was affirmed.

Analysis

Precedents Cited

The court’s analysis is anchored in a line of Maryland-consideration cases applied in Fourth Circuit FAA litigation:

Cheek v. United Healthcare Mid-Atlantic, Inc.
The core Maryland rule: “A promise becomes consideration for another promise only when it constitutes a binding obligation.” If the employer reserves the right “to alter, amend, modify, or revoke” the arbitration policy “at any time with or without notice,” the promise to arbitrate is illusory and the agreement fails for lack of consideration. The Trimble majority treats Cheek as the doctrinal baseline for evaluating unilateral-modification clauses in arbitration settings.
Hill v. Peoplesoft USA, Inc.
Cited for the definition and consequence of an “illusory promise” under Maryland law and for the proposition that an arbitration agreement must be a valid contract under state law. Hill helps the court frame the inquiry as ordinary contract formation, not a specialized FAA rule.
Coady v. Nationwide Motor Sales Corp.
The Fourth Circuit previously found illusory a modification clause allowing unilateral change “with or without notice.” Trimble relies on Coady to classify Entrata’s Change Clause as the same kind of unbounded unilateral power that destroys mutuality/consideration for arbitration.
Johnson v. Continental Fin. Co.
The decisive Fourth Circuit authority. Johnson held that, to preserve consideration in the face of a change-in-terms clause, Maryland law requires an “advance notice requirement” that constrains the modifying party by giving the other side “a chance to end the agreement before the change takes effect.” Johnson also rejected “post-hoc notice” (e.g., merely posting updated terms online) as inadequate because it “places no constraint” on the drafter’s ability to evade obligations. Trimble extends Johnson’s logic to a portal-based “visit binds you” structure where the user has no pre-effective chance to reject modifications.
Dhruva v. CuriosityStream, Inc., Henry Schein, Inc. v. Archer & White Sales, Inc., Moses H. Cone Mem'l Hosp. v. Mercury Constr. Corp., and Coady v. Nationwide Motor Sales Corp.
These cases collectively reinforce the arbitration framework: strong federal policy favoring arbitration exists, but courts must first determine whether a valid arbitration agreement exists; the pro-arbitration presumption does not apply to validity/formation.
First Options Chi., Inc. v. Kaplan, Spaulding v. Wells Fargo Bank, N.A., and CTI/DC, Inc. v. Selective Ins. Co. Am.
Cited for Maryland formation elements (mutual assent, definiteness, consideration) and the commitment to apply “ordinary state-law principles.”
Marshall v. Georgetown Mem'l Hosp. and Rowland v. Sandy Morris Fin. & Est. Plan. Servs., LLC
Used to situate the dispute in modern online contracting: “the digital age has changed the nature of contract formation,” but foundational contract principles remain controlling.
Credible Behavioral Health, Inc. v. Johnson
Invoked for Maryland’s “common sense” approach to contract interpretation; the majority uses it to reject Entrata’s argument that users can avoid new terms simply by not returning to the site, because notice and review are functionally impossible without immediate binding assent.

Legal Reasoning

Formation, not FAA policy, controls.
The court reiterates that the FAA’s enforcement mandate applies only once a valid agreement exists. The presumption favoring arbitration does not govern contract-formation disputes (relying on Coady v. Nationwide Motor Sales Corp. and the broader formation framework in Dhruva v. CuriosityStream, Inc.).
Maryland requires consideration; illusory promises are no consideration.
Under Cheek v. United Healthcare Mid-Atlantic, Inc., a mutual promise to arbitrate can be consideration, but only if both promises are binding. If one party can revoke or rewrite its promise at will, mutuality collapses.
The Change Clause applied to arbitration and was effectively unconstrained.
Following Johnson v. Continental Fin. Co., a contract-wide change-in-terms provision presumptively reaches the arbitration provision unless the contract says otherwise. Entrata’s Change Clause (“This Agreement may change from time to time”) was broad enough to permit changing the arbitration obligation itself.
No effective advance notice; no chance to end before changes take effect.
The majority treats the Notices Clause (“we will give you any notices … by posting them on [ResidentPortal] … you must check [ResidentPortal]”) as, at best, post-hoc notice. Under Johnson v. Continental Fin. Co., notice that arrives only through a mechanism that does not let the user reject changes before they bind is not a meaningful constraint.
Entrata’s “you can just not return” argument fails because returning is the only way to learn of changes, yet return triggers immediate binding.
The majority’s key functional insight is structural: the Terms state users are bound by the version in effect on the date of the visit, so a user who returns to check whether changes exist becomes bound immediately—before any practical opportunity to review and reject.
The relationship is “ongoing,” not a series of isolated one-off contracts.
The court rejects Entrata’s characterization that each portal payment creates a new contract that cannot be retroactively altered. It points to language about “version[s]” of an agreement, changes “from time to time,” and a “relationship resulting from the use of such services,” all suggesting continuing governance rather than transaction-by-transaction contracting.
Therefore: no consideration for arbitration; no agreement formed.
With Entrata retaining unilateral escape power, its promise to arbitrate is illusory under Cheek v. United Healthcare Mid-Atlantic, Inc., as applied through Coady v. Nationwide Motor Sales Corp. and Johnson v. Continental Fin. Co.. The motion to compel arbitration was properly denied.

Impact

The decision has practical consequences for online contracting—especially in Maryland-governed agreements within the Fourth Circuit:

Drafting constraints on unilateral modification clauses.
Providers who want enforceable arbitration clauses cannot reserve open-ended power to change terms “from time to time” while making changes effective upon site visit, absent a mechanism that gives users meaningful advance notice and a real opportunity to reject changes before they become binding.
Heightened risk for portal-based “hyperlink + checkbox” contracting.
Even where a user checks a box to proceed with payment, courts may focus on how the Terms define when a user is bound (“upon visit”) and whether the provider’s modification mechanics undermine consideration.
Class-action exposure may increase.
When arbitration is unavailable at the outset, defendants lose a key tool for managing aggregated statutory claims (here, MCALA/MCDCA and related consumer-protection claims).
Clear roadmap for enforceable updates.
The opinion implicitly points toward safer designs: advance notice outside the “visit binds you” moment, delayed effective dates, and opt-out/termination paths that can be exercised before new terms govern.

Complex Concepts Simplified

Consideration: The exchange of binding promises or value that makes a contract enforceable. In Maryland, an arbitration clause typically needs its own consideration, often satisfied by both sides making binding promises to arbitrate.
Illusory promise: A promise that looks like a commitment but does not actually bind the promisor—e.g., “I promise to arbitrate, unless I later change my mind whenever I want.” Under Cheek v. United Healthcare Mid-Atlantic, Inc., an illusory promise cannot serve as consideration.
Unilateral modification / change-in-terms clause: A contract term letting one party change the agreement later. Under Johnson v. Continental Fin. Co., such a clause threatens consideration unless it is meaningfully constrained—especially by advance notice that allows the other party to end the agreement before changes take effect.
Browsewrap: Online terms that purport to bind users through use of a website, typically via a hyperlink to terms rather than a standalone, clearly presented assent flow. The district court labeled the Terms “browsewrap” because the Terms stated users were bound upon visiting the portal.
Advance notice vs. post-hoc notice: “Advance notice” gives the user time to reject or exit before a change becomes effective. “Post-hoc notice” (e.g., posting revised terms on a site) informs the user only after the change is already binding, which Johnson v. Continental Fin. Co. treats as an inadequate constraint.

Conclusion

Kaitlyn Trimble v. Entrata, Inc. reinforces and operationalizes the Fourth Circuit’s Maryland-law rule that arbitration provisions fail for lack of consideration when embedded in terms that the drafter can unilaterally modify without meaningful, pre-effective notice and without giving users a genuine chance to end the agreement before modifications bind. By focusing on how “visit-based” binding and notice-by-posting function in practice, the court underscores that online contract architecture can itself render a promise to arbitrate illusory.

Note on the Dissent

Judge Rushing’s dissent reads the Change Clause differently, emphasizing that modifications are prospective and/or become binding only if the customer revisits the portal—making the customer, not Entrata, the gatekeeper of changes. The majority rejects that framing as inconsistent with the Terms’ “bound upon visit” structure and the lack of meaningful advance notice.
