Equitable indemnity in California is a court-made doctrine that lets a defendant who paid more than their fair share of a judgment or settlement recover the excess from other parties whose fault contributed to the same injury. Each party’s share is measured by their percentage of fault, not by headcount or by who signed a contract. The right exists by operation of law, and defendants typically assert it by filing a cross-complaint in the underlying lawsuit.
What the Doctrine Does
Equitable indemnity applies whenever two or more parties share liability to the same injured plaintiff for the same harm. The parties don’t have to have acted together, and they don’t have to be liable under the same legal theory. One might be sued for negligence, another for strict liability; what matters is that their separate conduct contributed to one injury. A surgeon and a hospital, a general contractor and a subcontractor, a bar and a drunk driver — any of those combinations can trigger indemnity rights if one of them ends up paying more than their proportional share.
Say a jury finds you 20% responsible for a plaintiff’s injuries but you paid the whole judgment. Equitable indemnity is what lets you go after the co-defendants who accounted for the other 80%.
How Fault Gets Apportioned
The modern version of the doctrine comes from American Motorcycle Assn. v. Superior Court (1978). Before that decision, California used an all-or-nothing rule that shifted the entire loss to whichever defendant was labeled “actively” negligent, leaving the “passively” negligent defendant off the hook. The California Supreme Court modified the rule to “permit, in appropriate cases, a right of partial indemnity, under which liability among multiple tortfeasors may be apportioned on a comparative negligence basis.”1Supreme Court of California Resources. American Motorcycle Assn. v. Superior Court
That’s what California courts now call comparative indemnity. A judge or jury assigns each party a percentage of fault, and each defendant’s share of the damages matches that percentage. A defendant found 30% at fault pays 30%, not zero and not the whole judgment.2Justia. American Motorcycle Assn. v. Superior Court
Where Proposition 51 Changes the Math
Voters passed Proposition 51 in 1986, and it changed how joint liability works depending on the type of damages. Under Civil Code section 1431.2, each defendant’s liability for non-economic damages — pain, suffering, emotional distress, loss of companionship — is several only. Each defendant pays their own percentage and no more.3California Legislative Information. California Civil Code 1431.2 – Several Liability for Non-Economic Damages
Economic damages are different. Medical bills, lost wages, property repair costs, and similar out-of-pocket losses stay subject to joint and several liability, so a plaintiff can still collect the full amount from any single defendant regardless of that defendant’s fault percentage. That’s where equitable indemnity does its real work today. For non-economic damages, Proposition 51 already keeps each defendant on the hook for only their share, so there’s usually nothing to redistribute.3California Legislative Information.

What You Have to Prove
A defendant pursuing equitable indemnity has to establish three things:
- Shared liability. You and the party you’re pursuing both owe a legal obligation to the same injured plaintiff for the same harm. The theory of liability doesn’t have to match.
- Payment. You actually paid something — a judgment or a settlement — that discharged all or part of the shared obligation. Potential future liability isn’t enough; money has to have changed hands.
- Disproportionate fault. There’s a basis to conclude you paid more than your proportionate share. A court or jury assigns fault percentages, and you recover the difference.
Bringing the Claim in an Active Lawsuit
The mechanism is a cross-complaint. Code of Civil Procedure section 428.10 lets any defendant file a cross-complaint against co-defendants or new parties as long as the claim arises out of the same events as the original suit.4California Legislative Information. California Code of Civil Procedure 428.10 – Cross-Complaint
Timing matters. A cross-complaint against the party who sued you has to be filed before or at the same time as your answer. A cross-complaint against anyone else, including a new third-party defendant, can be filed any time before the court sets a trial date. After that, you need the court’s permission, which can be granted “in the interest of justice at any time during the course of the action.”5California Legislative Information. California Code of Civil Procedure 428.50 – Filing of Cross-Complaint
Bringing in a new party also means serving them with the cross-complaint and a summons. Filing alone doesn’t give the court jurisdiction over someone who wasn’t already in the case.
When a Co-Defendant Settles First
This is the pressure point in most multi-defendant cases. Under Code of Civil Procedure section 877.6, a settling defendant can ask the court to find that the settlement was made in good faith. If the court agrees, the remaining defendants lose all rights to seek equitable indemnity or contribution from the settling defendant.6California Legislative Information. California Code of Civil Procedure 877.6 – Good Faith Settlement Determination
The remaining defendants aren’t stripped of everything. The total claim against them gets reduced by the settlement amount. But if the settling defendant paid a light amount relative to their fault, the non-settling defendants absorb the difference. That’s the reason parties push to settle early, and it’s the reason a non-settling defendant may want to fight a settlement’s good faith finding.
Contesting Good Faith
The burden is on the party challenging the settlement. Courts weigh the factors laid out in Tech-Bilt, Inc. v. Woodward-Clyde & Associates (1985):7Justia. Tech-Bilt, Inc. v. Woodward-Clyde and Associates
- A rough approximation of the plaintiff’s total recovery and the settling defendant’s proportionate share of liability
- The settlement amount relative to what the settling defendant would likely owe after trial
- The settling defendant’s financial condition and insurance policy limits
- How settlement proceeds are allocated when there are multiple plaintiffs
- Any evidence of collusion or fraud aimed at the non-settling defendants
Courts recognize that settling defendants reasonably pay less than a full-trial verdict, so a discount doesn’t by itself signal bad faith. The question is whether the number is “grossly disproportionate” to a reasonable estimate of the settling defendant’s liability.7Justia. Tech-Bilt, Inc. v. Woodward-Clyde and Associates
The Deadline to Object
The settling party files a good faith application and serves it on the other parties. Non-settling defendants then have 25 days from mailing, or 20 days from personal service, to file a motion contesting good faith. If nobody objects in that window, the court can approve the settlement without a hearing.6California Legislative Information. California Code of Civil Procedure 877.6 – Good Faith Settlement Determination
When the Clock Starts
An equitable indemnity claim doesn’t accrue when the plaintiff is injured. It accrues when you actually pay the judgment or settlement, because until then there’s no overpayment to recover. California courts apply a two-year limitations period from the date of payment. Miss that window and the right to recover from co-defendants goes away, even if the underlying case took years to resolve.
How It Differs From Contribution and Contractual Indemnity
Two related tools sit next to equitable indemnity, and they aren’t the same thing.
Contribution under Code of Civil Procedure section 875 splits a judgment equally among joint judgment debtors regardless of fault, and only after a defendant pays more than their pro rata share. Equitable indemnity divides by fault instead of by headcount, which is why it has largely overtaken contribution in California practice. The contribution statute expressly preserves indemnity rights.8California Legislative Information. California Code of Civil Procedure 875 – Contribution Among Joint Tortfeasors
Contractual indemnity is different again. It comes from a written agreement — often in a construction contract, lease, or services deal — and follows whatever the contract says. A contract clause might obligate one party to cover 100% of certain losses regardless of actual fault. When a contract clause reaches the specific loss, it usually controls. Where it doesn’t reach, equitable indemnity can still fill the gap, and defendants often plead both theories as alternatives.
Attorney Fees
California follows the general rule that each side pays its own attorney fees unless a statute or contract says otherwise, and equitable indemnity claims usually don’t get you the fees you spent chasing them. The narrow exception is the “tort of another” doctrine, which allows fee recovery when someone else’s wrongful conduct forced you into litigation with a third party to protect your interests. California courts have added an “exceptional circumstances” requirement so the exception doesn’t swallow the rule, so plan on paying your own fees unless the facts are unusual.
