Common counts survive alongside an express contract at the pleading stage. Quantum meruit does not — unless the contract's enforceability or scope is genuinely in dispute. Here's how courts draw the line.

Common Counts and Quantum Meruit in Cross-Complaints — What Survives Demurrer

Two recovery theories that commercial litigants routinely misread: common counts and quantum meruit. The first survives alongside an express contract at the pleading stage. The second does not — unless the contract's enforceability or scope is genuinely in dispute. Knowing which is which, and how courts draw the line, determines whether your cross-complaint survives the first round of demurrers.

The Motion

Cross-complainant pleads breach of contract and, alongside it, common count and quantum meruit theories. Cross-defendant demurs, arguing that the express contract governs and alternative theories are unavailable. The question is whether those alternative claims can survive at the pleading stage.

What the Law Requires

Common Counts. California permits alternative theories at the pleading stage. A common count — open book account, account stated, goods sold and delivered, services rendered, money had and received — does not fail on demurrer merely because an express contract covers the same subject matter. The argument that "plaintiff has an express contract, so common counts are unavailable" is not a pleading-stage demurrer ground. Utility Audit Co., Inc. v. City of Los Angeles (2003) 112 Cal.App.4th 950, 958.

Demurrer to a common count succeeds only when the count fails to allege: (1) an indebtedness, (2) the amount owed, or (3) a transaction giving rise to the debt. Each count must state these elements. The label "common count" is not self-sufficient — the underlying transactional facts must appear in the pleading.

Quantum Meruit. The standard is different. Quantum meruit — recovery for the reasonable value of services rendered — is available as an alternative theory when the enforceability or scope of the governing contract is disputed. It does not lie when an enforceable contract governs the same services at a definite price. "If there is an enforceable contract governing the parties' relationship, quantum meruit recovery is not available." Wall Street Network, Ltd. v. New York Times Co. (2008) 164 Cal.App.4th 1171, 1182.

Elements of quantum meruit: (1) services rendered to cross-defendant; (2) at cross-defendant's request; (3) without agreed compensation or with a reasonable expectation of payment; (4) reasonable value. All four must appear in the pleading.

What the Corpus Shows

Common Counts — What Survives. CAB v. Champion Power Equipment (L.A. Superior Ct. No. 25NWCV03878, May 2026) — demurrer overruled to cross-complaint asserting contract claims alongside common-count theories in a commercial goods dispute. The court applied the standard rule: at the pleading stage, a plaintiff or cross-complainant may pursue both express contract and common counts in the alternative. The existence of a contract does not make common counts legally unavailable.

The practical limit that does not appear in the corpus but controls the outcome: if the cross-complaint itself acknowledges that the contract is valid and enforceable, and seeks the contract price under a common count label, courts may sustain. The alternative theory is not a mechanism for recovering the same dollar figure twice under a different heading while conceding the contract governs. Common counts are alternative theories, not duplicative ones.

Quantum Meruit — The Contract Boundary. The demurrer line is cleaner for quantum meruit. Where the cross-complaint acknowledges an express, enforceable contract covering the same services at a definite price, quantum meruit is unavailable and demurrer is sustained. The theory survives where: (1) the existence, scope, or price term of the contract is genuinely in dispute; or (2) the cross-complainant provided services beyond the contract's scope. Maglica v. Maglica (1998) 66 Cal.App.4th 442.

At the pleading stage, the cross-complainant need not concede the contract is unenforceable to assert quantum meruit as an alternative under CCP § 428.30. The election between theories is decided at trial, not on demurrer — unless the cross-complaint itself conclusively establishes the contract's enforceability by its own allegations.

What Counsel Does

If you are the moving party (demurring to common counts and quantum meruit):

For common counts: confirm that the count fails to allege an indebtedness, the amount owed, or a transaction giving rise to the debt. The argument that "a contract exists" alone does not win on demurrer. You need a missing element.
For account stated: check whether the cross-complaint alleges that the parties previously agreed on a balance due. Account stated requires mutual agreement on the amount — if that agreement is not alleged, the count fails.
For quantum meruit: the stronger demurrer ground is that the cross-complaint's own allegations establish an enforceable contract governing the same services at a definite price. If the cross-complaint quotes or incorporates the contract and then seeks "reasonable value" for the same work, that is the demurrer.
Do not rely solely on "a contract exists" to defeat common counts. The pleading-stage rule is clearly established against you. Focus on missing transactional elements or the specific quantum meruit enforceability argument.

If you are the opposing party (defending the cross-complaint):

For common counts: plead each count as a separately numbered cause of action. Open book account requires (1) a book account; (2) a balance due; (3) that remains unpaid. Account stated requires (1) prior transactions establishing an amount; (2) a statement of that amount between the parties; (3) agreement. Money had and received requires (1) cross-defendant received money; (2) at cross-complainant's expense; (3) that in equity and good conscience should be returned. Plead the specific dollar amount for each count.
For quantum meruit: if the contract's enforceability or scope is disputed, say so explicitly. Do not plead quantum meruit alongside a contract claim while also conceding the contract is valid and covers the work at issue. The inconsistency will defeat you.
Plead quantum meruit under CCP § 428.30 as an alternative. You do not need to admit the contract is unenforceable — you need to allege facts that would support recovery if the contract turns out not to govern.
For the reasonable value element: describe the services and state the dollar amount you contend is their reasonable value. "Reasonable value in an amount to be proven at trial" without any factual content is at risk.
