CALIFORNIA CONTRACTS DISTINCTIONS
California is a Restatement-and-UCC state: it follows common-law contract doctrine for service, employment, and real-property agreements and has adopted Article 2 of the Uniform Commercial Code (codified at California Commercial Code §§ 2101 et seq.) for transactions in goods. Most black-letter rules you learned for the MBE — offer, acceptance, the mailbox rule, the parol evidence rule, mutual mistake, anticipatory repudiation, expectation damages — apply unchanged. But California's Civil Code contains a number of codified rules that displace or sharpen the majority common-law position, and several California statutes (non-compete voidness, the liquidated-damages presumption, the implied covenant of good faith) are heavily tested fact patterns. This page isolates those departures.
📘 This page covers only California's departures from national/majority law. For the full doctrine, see the MBE Contracts & Sales Long Outline.
I. CONSIDERATION, MODIFICATION, AND RELEASE
California codifies consideration in the Civil Code and softens several common-law rules about modifying and discharging contracts. The headline departures involve oral modification of written contracts and the writing requirement for releases.
A. Consideration Defined (CCC § 1605)
CA Rule: Civil Code § 1605 defines good consideration as "any benefit conferred, or agreed to be conferred, upon the promisor . . . or any prejudice suffered, or agreed to be suffered" by the promisee. This tracks the common-law benefit/detriment formulation. National: bargained-for legal detriment under Restatement (Second) § 71. California: same substance, but expressed by statute, and a written instrument is presumptive evidence of consideration (CCC § 1614), with the burden of showing want of consideration falling on the party attacking the contract (CCC § 1615).
B. Modification of Written Contracts (CCC §§ 1697–1698)
CA Rule: Civil Code § 1698 governs modification. A contract in writing may be modified by (1) a later written contract; (2) an oral agreement to the extent it is executed; (3) an oral agreement supported by new consideration; or (4) an oral agreement if the contract does not require modifications to be in writing (subject to the Statute of Frauds). National: the common law's pre-existing duty rule requires fresh consideration for any modification, and the UCC (§ 2-209) allows good-faith modification of goods contracts without new consideration. California: for non-goods written contracts, § 1698 expressly permits oral modification where it has been executed or supported by new consideration — a more structured, statute-driven analysis than the common-law default.
C. Release Must Be in Writing (CCC § 1541)
CA Rule: Civil Code § 1541 provides that an obligation is extinguished by a release given by the creditor "with or without new consideration" — but a release is binding only if in writing or executed. Practically, an executory oral release without consideration is ineffective. National: common law generally requires consideration or a writing under seal for a release. California: a written release needs no consideration, which is a meaningful trap.
ESSAY WRITING TIP: When a fact pattern shows the parties changing a signed written contract by handshake, do not stop at the common-law pre-existing duty rule. Walk through Civil Code § 1698's four routes: later writing, executed oral agreement, new consideration, or no no-oral-modification clause. State each and apply the facts; that statutory framework is what California graders reward.
CA BAR TIP: Memorize the section numbers — § 1605 (consideration), § 1698 (modification), § 1541 (release). California examiners frequently reward candidates who cite the Civil Code section, even loosely, because it signals you know this is a codified, not purely common-law, jurisdiction.
II. STATUTE OF FRAUDS (CCC § 1624)
California's Statute of Frauds is codified at Civil Code § 1624 and largely mirrors the traditional MY LEGS categories, but with California-specific additions and a notable real-estate agent provision.
A. Covered Categories
CA Rule: Section 1624 requires a writing for: agreements not performable within one year; promises to answer for the debt of another (suretyship); agreements made upon consideration of marriage; contracts for the sale of real property or an interest therein; leases longer than one year; and — distinctively — an agreement authorizing or employing an agent or broker to purchase or sell real estate for compensation (§ 1624(a)(4)). National: the broker-employment writing requirement is not universal. California: a real-estate listing or buyer-representation agreement must be in writing to be enforceable for commission.
B. Loan Commitments and Other Additions
CA Rule: Section 1624(a)(7) requires a writing for a contract by which a person agrees to lend money or extend credit in an amount greater than $100,000, made by a person engaged in the business of lending, where the borrower is not primarily for personal/family/household purposes. National: no general writing requirement for loan commitments. California: large commercial loan commitments fall within the Statute of Frauds.
ESSAY WRITING TIP: After identifying the relevant § 1624 category, always test the standard exceptions — part performance for land (acts unequivocally referable to the contract), full performance taking a one-year contract out of the statute, promissory estoppel, and the UCC merchant-confirmation and specially-manufactured-goods exceptions for goods. California recognizes all of these; saying so completes the analysis.
CA BAR TIP: Watch for the broker-commission and large-loan provisions — they are uniquely California and are exactly the kind of detail an essay grader inserts to separate candidates who memorized only MBE Statute of Frauds categories from those who learned California law.
III. NON-COMPETE AGREEMENTS — VOID (CCC § 16600)
This is California's single most important and most heavily tested contract distinction. California's Business and Professions Code § 16600 declares that, with narrow statutory exceptions, "every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void."
A. The General Rule and Its Breadth
CA Rule: Employee covenants not to compete are void as a matter of law, not merely subject to a reasonableness test. The California Supreme Court in Edwards v. Arthur Andersen LLP (2008) rejected any "narrow restraint" exception and held § 16600 means what it says. As of 2024, Bus. & Prof. Code §§ 16600.1 and 16600.5 make it unlawful even to attempt to enforce such a clause and require employers to notify affected current and former employees. National: most states enforce non-competes that are reasonable in scope, duration, and geography (the rule of reason). California: reasonableness is irrelevant; the clause is void.
B. Statutory Exceptions
CA Rule: The narrow exceptions are: (1) a person selling the goodwill of a business or selling/disposing of all ownership interest (§ 16601); (2) dissolution of, or dissociation from, a partnership (§ 16602); and (3) dissolution of, or sale of interest in, a limited liability company (§ 16602.5). Outside these, even a non-solicitation-of-customers clause that operates as a de facto restraint is suspect. National: such restraints are routinely enforced if reasonable. California: only the sale-of-business and partnership/LLC-dissolution exceptions survive.
EXAMPLE: An engineer signs an employment contract promising not to work for any competitor within California for two years after leaving. Under the rule of reason in most states this might be reduced and enforced. In California the clause is simply void under § 16600; the engineer may immediately work for a competitor, and the former employer may face liability for trying to enforce it.
ESSAY WRITING TIP: If an essay shows a departing employee bound by a non-compete, lead with § 16600 and Edwards: the clause is void. Then check whether a § 16601/16602 exception applies (sale of a business or partnership dissolution). Distinguish a lawful trade-secret protection (enforceable under the Uniform Trade Secrets Act) from an unlawful naked restraint — the former survives, the latter does not.
CA BAR TIP: This is a near-certainty topic. The grader wants to see you reject the MBE "reasonableness" balancing entirely and apply California's flat rule. Mentioning the 2024 amendments (notice duty, unlawful to enforce) shows current knowledge and earns points.
IV. LIQUIDATED DAMAGES — PRESUMED VALID (CCC § 1671)
California reverses the common-law starting presumption for liquidated-damages clauses in most contracts.
A. The Statutory Presumption
CA Rule: Civil Code § 1671(b) provides that in contracts other than consumer and residential-lease contracts, a liquidated-damages provision is valid unless the party challenging it proves it was unreasonable under the circumstances existing when the contract was made. National (common law): a liquidated-damages clause is presumptively an unenforceable penalty unless the proponent shows damages were difficult to estimate and the amount is a reasonable forecast. California: in commercial contracts the burden flips — the clause is presumptively valid and the challenger must prove unreasonableness.
B. Consumer and Lease Contracts
CA Rule: Section 1671(c)–(d) keeps the protective common-law rule for consumer contracts and residential leases: such clauses are void unless the parties agreed they would and it was impracticable or extremely difficult to fix actual damages. National: similar protective stance. California: the distinction between commercial (presumed valid) and consumer/residential (presumed void) is the tested point.
ESSAY WRITING TIP: Identify the contract type first. If it is a commercial deal, state that § 1671(b) presumes validity and put the burden on the challenger. If it is a consumer or residential-lease deal, flip to § 1671(c)/(d) and apply the stricter "impracticable to fix actual damages" test. Naming the subsection signals mastery.
CA BAR TIP: The classic trap is to apply the MBE penalty analysis (difficult-to-estimate plus reasonable-forecast) to a commercial California contract. That gets the burden backwards. In commercial contracts, assume valid and make the other side prove otherwise.
V. IMPLIED COVENANT OF GOOD FAITH AND FAIR DEALING
Every California contract contains an implied covenant of good faith and fair dealing. The California-specific question is when its breach gives rise to tort rather than mere contract liability.
A. Contract Versus Tort Recovery
CA Rule: Breach of the implied covenant ordinarily sounds in contract, yielding contract damages only. California permits tort recovery for breach of the covenant essentially only in the insurance context — the "insurance bad faith" cause of action — because of the special, quasi-fiduciary relationship between insurer and insured. In Foley v. Interactive Data Corp. (1988), the California Supreme Court refused to extend tort recovery for breach of the implied covenant to the ordinary employment relationship. National: most jurisdictions limit good-faith breach to contract damages and likewise confine bad-faith tort liability to insurance. California: Foley is the leading authority cabining tort recovery to insurance.
EXAMPLE: An insurer unreasonably refuses to pay a covered claim. The insured may sue in tort for bad faith and recover consequential and possibly punitive damages. An at-will employee fired in bad faith generally recovers only contract damages, not tort damages, under Foley.
ESSAY WRITING TIP: When you see the implied covenant, state the default — contract damages — then ask whether this is an insurance relationship. If yes, discuss tort bad-faith liability; if no (employment, ordinary commercial), cite Foley to confine recovery to contract. This two-step is the California-graded analysis.
CA BAR TIP: Do not award tort or punitive damages for a garden-variety breach of the good-faith covenant. The grader is testing whether you know Foley limits tort exposure to insurance.
VI. UNCONSCIONABILITY AND THIRD-PARTY BENEFICIARIES
California applies the standard procedural/substantive unconscionability sliding scale but has a well-developed line of arbitration cases, and it codifies third-party beneficiary rights.
A. Unconscionability — Procedural and Substantive (Armendariz)
CA Rule: Under Armendariz v. Foundation Health Psychcare Services (2000), an agreement (typically a mandatory employment arbitration clause) is unenforceable only if it is both procedurally and substantively unconscionable, evaluated on a sliding scale — the more of one, the less of the other is needed. Civil Code § 1670.5 codifies the court's power to refuse to enforce an unconscionable clause or contract. National: same two-prong sliding-scale framework derived from UCC § 2-302. California: Armendariz adds specific minimum requirements for lawful employment arbitration (neutral arbitrator, adequate discovery, written award, no limits on statutory remedies, employer pays arbitration-unique costs).
B. Third-Party Beneficiaries (CCC § 1559)
CA Rule: Civil Code § 1559 provides that "a contract, made expressly for the benefit of a third person, may be enforced by him." California uses an intended/incidental distinction consistent with the Restatement but anchors enforcement in this statute. National: Restatement intended-beneficiary analysis. California: same result, codified.
ESSAY WRITING TIP: For an arbitration or adhesion-clause essay, structure the answer around procedural unconscionability (oppression/surprise, adhesion) and substantive unconscionability (overly harsh, one-sided terms), then apply the sliding scale and the Armendariz fairness factors if employment arbitration is involved.
CA BAR TIP: Remember that the Federal Arbitration Act preempts some California arbitration rules (e.g., AT&T Mobility v. Concepcion on class-waiver bans). If federal law governs the transaction, note the preemption issue rather than mechanically applying state unconscionability doctrine.
VII. CALIFORNIA DISTINCTIONS CHECKLIST
- Modification of a written contract — apply Civil Code § 1698's four routes (later writing; executed oral; new consideration; no no-oral-modification clause), not just the common-law pre-existing duty rule.
- Releases must be in writing or executed (§ 1541); a written release needs no consideration.
- Statute of Frauds (§ 1624) adds real-estate broker-employment agreements and large commercial loan commitments (over $100,000) to the standard categories.
- Employee non-competes are void under Bus. & Prof. Code § 16600 (Edwards); no reasonableness test. Exceptions only for sale of business goodwill (§ 16601) and partnership/LLC dissolution (§§ 16602, 16602.5).
- Liquidated-damages clauses in commercial contracts are presumed valid under § 1671(b); the challenger bears the burden. Consumer/residential-lease clauses remain presumptively void (§ 1671(c)–(d)).
- Breach of the implied covenant of good faith yields tort/bad-faith recovery essentially only in insurance; Foley confines employment and ordinary contracts to contract damages.
- Unconscionability requires both procedural and substantive elements on a sliding scale (§ 1670.5); employment arbitration must satisfy the Armendariz minimum fairness requirements.
- Third-party beneficiaries enforce contracts under Civil Code § 1559 (intended, not incidental).
- A written instrument is presumptive evidence of consideration (§ 1614); the burden to show want of consideration falls on the attacking party (§ 1615).
