Yes. Under California law, you can challenge and sometimes void an arbitration clause that is both procedurally and substantively unconscionable. The California Supreme Court’s ruling in Ramirez, the older Armendariz framework, and Code of Civil Procedure section 1281.98 all give employees real leverage. If you signed one of these agreements at onboarding, save every document you got that day and talk to a lawyer before your employer files a motion to compel arbitration.
TL;DR:
- Courts will scrutinize onboarding paperwork more closely, especially when multiple unfair provisions are interconnected or rushed signing suggests procedural unconscionability.
- Challengers should preserve all related documents immediately, including offer letters, signed agreements, and any HR communications, to strengthen their unconscionability case.
- If an employer fails to pay arbitrator fees within the statutory deadline, the case can be sent back to court without reaching unconscionability issues.
- The sliding scale shows that significant unfair terms require less procedural oppression to invalidate, making detailed facts critical to success.
- Legal challenges should focus on demonstrating procedural unfairness, unfair terms, and the employer’s drafting practices, especially given recent courts’ increased skepticism of adhesion contracts.

The Case Law Behind Arbitration Unconscionability in California
California’s unconscionability doctrine didn’t spring up overnight, and it hasn’t stopped moving. The single biggest recent shift came from the California Supreme Court’s decision in Ramirez v. Charter Communications, Inc., which found several provisions in Charter’s employment arbitration agreement substantively unconscionable, including a shortened limitations period, a lack of mutuality favoring the company, and an attorney fee provision that punished employees for bringing claims. The court sent the case back down for a severance analysis rather than deciding outright whether the whole agreement should fall, which tells you something important: even the state’s highest court treats severance as a fact-specific question, not a formality.
Before Ramirez, the governing case was Armendariz v. Foundation Health Psychcare Services, Inc., decided in 2000. Armendariz set the floor for mandatory employment arbitration in California: a neutral arbitrator, adequate discovery, a written decision, and no limits on the remedies an employee could otherwise get in court. Any clause that falls short of those baseline protections is vulnerable, and Armendariz remains the doctrinal backbone every subsequent case builds on.
Two more decisions matter if your dispute touches wage claims under the Private Attorneys General Act. Iskanian v. CLS Transportation held that employees cannot waive their right to bring representative PAGA claims on behalf of the state, even in an arbitration agreement. Viking River Cruises, Inc. v. Moriana, decided by the U.S. Supreme Court, complicated that picture by ruling that individual PAGA claims can be compelled to arbitration while non-individual claims proceed separately in court. The practical effect: your individual claim might get pulled into arbitration even when your representative claim stays in court.
Appellate courts have applied these principles in ways worth knowing about:
- Cook v. University of Southern California invalidated a clause with an unlimited scope and duration, finding the breadth itself substantively unfair.
- A Ninth Circuit panel in Ronderos declined to compel arbitration where the formation process showed clear procedural oppression.
- Lower courts increasingly treat an agreement as “permeated” by unconscionable terms when the one-sided provisions interlock, which cuts against severing just one bad clause and enforcing the rest.
None of these rulings exist in a vacuum. Courts read them together, and the trend line points toward closer scrutiny of onboarding paperwork specifically.
Procedural vs. Substantive Unconscionability: The Sliding Scale Explained
California doesn’t require you to prove one giant unfairness. It requires two separate showings, weighed against each other on a sliding scale.
Procedural unconscionability looks at how the agreement was formed. Was it a take-it-or-leave-it contract of adhesion? Did you get it buried in a stack of onboarding paperwork with no real chance to read it or negotiate? Did the company keep the only copy? The Ramirez case summary notes that rushed signing and no meaningful opportunity to review the terms can materially increase procedural unconscionability, even when the underlying terms are only moderately unfair on their own.
Substantive unconscionability looks at the actual terms. Common red flags include:
- One-sided fee-shifting that makes the employee pay costs the employer would normally bear.
- A shortened statute of limitations that cuts off claims before an employee would otherwise know they have one.
- Unlimited scope or duration language that sweeps in disputes with no logical connection to the job.
- Carveouts that let the employer sue in court for certain claims (trade secrets, unfair competition) while forcing the employee into arbitration for everything else.
- Discovery limits that prevent an employee from getting the documents needed to prove a discrimination or wage claim.
The sliding scale is where the doctrine gets interesting. As the Berkeley Law analysis of California unconscionability explains, a high degree of substantive unfairness requires less procedural oppression to invalidate the agreement, and the reverse holds too. A modestly rushed signing combined with three or four one-sided terms can be enough. A near-total absence of choice in how the contract was presented can tip the balance even if only one term looks unfair on paper. This is the unconscionability test California courts actually use, and it rewards a lawyer who can lay out both sides of the scale rather than hammering on just one.
FAA Preemption, the California Arbitration Act, and SB 82
Federal law sets outer boundaries on how far California can go, and understanding where those boundaries sit changes how you frame a challenge.
The Federal Arbitration Act preempts state rules that single out arbitration for special disfavor. That’s the core holding behind AT&T Mobility v. Concepcion, where the U.S. Supreme Court struck down California’s Discover Bank rule because it effectively required classwide arbitration to be available, a requirement that conflicted with arbitration’s basic bilateral structure. But the FAA has a saving clause, and that clause is the reason unconscionability challenges still work: generally applicable contract defenses, the kind that would void any contract regardless of whether it involves arbitration, survive preemption. That’s why California courts and litigants frame these challenges around adhesion, surprise, and one-sided terms rather than arguing arbitration itself is disfavored.
- The FAA’s saving clause lets unconscionability defenses stand because they apply to all contracts, not just arbitration agreements.
- Concepcion and its progeny bar rules that treat arbitration worse than other contract types.
- California’s own statute, the California Arbitration Act, still governs procedure once a court agrees an agreement can be challenged.
One of the sharpest procedural tools sits in Code of Civil Procedure section 1281.98: if the employer, as the drafting party, fails to pay arbitrator fees within the statutory deadline, it can forfeit the right to compel arbitration altogether, sending the case back to court.
A newer wrinkle arrives with SB 82, a statutory update codified at Civil Code section 1670.15, which recently came into effect. It narrows how broadly a consumer arbitration clause can sweep, limiting “any claims” language so it only covers disputes actually arising from the good or service at issue. Legal commentary tracking the rollout of SB 82 already flags that businesses will likely argue the law singles out arbitration and is therefore preempted by the FAA, the same argument that sank the Discover Bank rule. Expect this fight to play out in the courts over the next year or two, and expect California to keep legislating around the edges the FAA leaves open.
Will the Court Sever the Bad Clause or Throw Out the Whole Agreement?
Courts have three options once they find unconscionable terms, and which one you get depends heavily on how tangled the bad provisions are with the rest of the contract.
Civil Code section 1670.5 governs severance. A court can strike the offending clause and enforce the rest, refuse to enforce the arbitration agreement at all, or limit the application of certain terms to avoid an unconscionable result. Which path a judge takes turns on what practitioners call the “permeation” doctrine: when unconscionable terms are so intertwined with the rest of the agreement that removing them would require the court to rewrite the contract rather than edit it, severance becomes far less likely.
Courts weigh several factors when deciding:
- How many unlawful terms exist, and how central each one is to the agreement’s core function.
- Whether the one-sidedness runs in a single direction (employer favored) across multiple clauses, suggesting a drafting pattern rather than an isolated mistake.
- The formation context: rushed signing, no negotiation, standardized company-wide language.
A 2024 analysis of the sliding-scale approach from Ogletree’s employment law team makes a useful practical point: when multiple interlocking one-sided provisions exist in the same onboarding document, courts increasingly find the whole agreement permeated rather than salvageable one clause at a time. That’s a meaningfully different outcome than losing one bad fee-shifting term while the rest of the agreement stands. Full invalidation sends your case to court. Partial severance might still send you to arbitration, just on fairer terms. Knowing which outcome your facts point toward changes how you should be litigating from day one.
How to Actually Challenge an Arbitration Clause in California
If you think your arbitration agreement is unconscionable, treat the first two weeks after you realize it like a discovery sprint, because the paper trail you preserve now becomes your evidence later.
- Preserve everything from onboarding. Pull your offer letter, the arbitration agreement itself, any HR emails referencing the signing, and note the exact date and setting where you signed. If a coworker witnessed the rushed pace of onboarding, get their name and contact information now, while memories are fresh.
- Draft a declaration describing the signing circumstances. Courts want specifics: how much time you had to read the agreement, whether anyone explained it, whether you got a copy, whether you were told signing was optional. Vague statements about feeling pressured carry far less weight than a timeline with dates and names.
- Oppose the motion to compel arbitration with a focused unconscionability argument. Your opposition should map your facts onto both prongs of the test explicitly, not just gesture at unfairness generally.
- Request limited discovery on drafting practices. Ask for evidence showing whether the same clause was used company-wide, which supports an adhesion argument, and any internal communications about the fee-shifting or scope language.
- Check whether the employer paid arbitrator fees on time. If not, invoke CCP §1281.98 immediately. Missing that statutory deadline can hand you an outright win on the forum question without ever reaching the merits of unconscionability.
Timing matters more than most employees realize. Opposition deadlines to a motion to compel arbitration are short, generally measured in weeks, not months, and a botched declaration or a missed filing window can cost you the argument before a judge ever reaches the substance.
Pro Tip: Ask your former or current employer, in writing, for a copy of the arbitration agreement and the arbitration provider’s invoice history. If they can’t produce proof of timely fee payment, you may have a fast, clean path back to court that doesn’t require litigating unconscionability at all.
The Fee-Payment Rule Most Employees Never Use
Section 1281.98 gets overlooked constantly, and that’s a mistake. The statute sets a default deadline, generally 30 days from the invoice due date, for the party who drafted the arbitration agreement to pay its share of arbitration costs. Miss that deadline, and the drafting party can lose the right to force the case into arbitration at all.
Practitioners tracking this rule note that chasing proof of payment is one of the most underused tools available to employees, because it converts a fight over legal doctrine into a fight over a calendar date, which is far easier to prove.
- Send a written request for the arbitrator’s invoice and proof of payment date as soon as arbitration is initiated.
- If payment is late, file a notice with the court or arbitration provider citing the statutory forfeiture provision.
- Use fee-shifting language in the agreement itself as evidence of substantive unconscionability if the same clause that triggered the payment dispute also imposes one-sided costs on you.
Courts have shown little patience for drafting parties who miss these deadlines and then argue the delay was harmless. The rule exists precisely because the legislature wanted a bright-line consequence, not a negotiable one.
Why This Guide Draws on Javitch Law Office’s California Litigation Work
Javitch Law Office is a California-based civil rights firm that litigates employment discrimination, consumer protection, and constitutional claims, work that regularly puts the firm on the opposite side of arbitration clauses drafted to limit employee remedies. This guide reflects that practical experience with how California courts actually apply Ramirez and Armendariz in contested motions, not just how the opinions read on paper. Author Mark has covered California consumer protection issues, including the state’s 90 day pricing rule and credit card surcharge law, for the firm’s blog.
Where This Doctrine Is Headed Next
Courts are scrutinizing onboarding paperwork harder than they did five years ago, and Ramirez accelerates that trend. SB 82 aims to strengthen the hand of consumers and employees, but legal challenges over FAA preemption are anticipated before it settles into practice. My advice stays simple: act fast, preserve every document from the day you signed, and get counsel involved before you’re stuck defending a motion to compel on a deadline you didn’t see coming.

Talk to Javitch Law Office About Your Arbitration Agreement
Some law offices give California employees something a generic legal referral service can’t: direct experience litigating one-sided arbitration provisions that show up in discrimination and wage disputes, beyond just general familiarity with contract law.
If you’re staring down a motion to compel arbitration or you suspect the agreement you signed at onboarding was written to box you out of court, gather your offer letter, the signed arbitration clause, any HR emails from the signing period, and a rough timeline of how the paperwork was presented to you. Those four items are usually enough for an initial case evaluation. The firm’s discrimination practice handles employment matters where arbitration clauses frequently intersect with bias claims, and where PAGA or class issues are in play, the consumer class action team can evaluate whether representative claims survive even if individual claims get compelled to arbitration. Reach out through Javitchlawoffice to start a case evaluation before you respond to any motion.

FAQ
What makes an arbitration agreement unconscionable in California?
An agreement is unconscionable when it shows both procedural unfairness in how it was formed, like a rushed adhesion contract, and substantive unfairness in its terms, like one-sided fee-shifting or a shortened limitations period, weighed together on a sliding scale.
Is arbitration enforceable in California?
Yes, arbitration agreements are generally enforceable under both the Federal Arbitration Act and the California Arbitration Act, but California courts can refuse enforcement when an agreement meets the state’s unconscionability test.
Can unconscionable contracts be voided in California?
Yes. Under Civil Code section 1670.5, a court can refuse to enforce an unconscionable clause entirely, or it can sever the offending term and enforce the rest, depending on how deeply the unfair provisions permeate the agreement.
What makes an arbitration clause unenforceable?
Common defects include a lack of mutuality favoring the employer, unlimited scope or duration, discovery limits that block an employee from proving statutory claims, and an employer’s failure to pay arbitration fees on time under CCP §1281.98.
Can an employer force PAGA claims into arbitration?
Individual PAGA claims can be compelled to arbitration under Viking River Cruises v. Moriana, but representative claims brought on behalf of the state generally cannot be waived, following Iskanian v. CLS Transportation.
