Piercing the Corporate Veil in California: When the Owner Is Liable
A corporation or LLC is supposed to be a wall between the business’s debts and the owner’s personal assets. In most cases it is. But California courts will look through that wall — “pierce the corporate veil” — when an owner has run the entity as an extension of themselves and letting the entity absorb the loss would be unjust. The owner on the other side of the wall is called the alter ego. This article is written for both readers: the creditor wondering whether the owner can be reached, and the owner wondering whether the entity really protects them.
What limited liability normally means
The default rule is separateness. A corporation is a legal person distinct from its shareholders, officers, and directors, with its own debts. California’s LLC statute says the same thing directly: an LLC’s debts, whether they arise in contract, tort, or otherwise, are solely the LLC’s, and they do not become a member’s or manager’s debts just because that person acted as a member or manager. When a properly run entity is sued, the judgment is against the entity and the creditor collects from the entity’s assets.
That protection has always had limits that have nothing to do with veil piercing. An owner who personally co-signs or guaranties a loan is liable on that promise. An owner who personally commits a tort — the fraud, the negligent act — is liable for their own conduct no matter what entity they were working through. Veil piercing is the third route: holding the owner liable for the entity’s obligation, not their own, because the entity was never really separate.
The two-part test
California courts apply a two-part test, stated in Sonora Diamond Corp. v. Superior Court (2000) 83 Cal.App.4th 523 and in many cases before and since. First, there must be such a unity of interest and ownership between the entity and its owner that the separate personalities of the two do not in reality exist. Second, there must be an inequitable result if the acts in question are treated as those of the entity alone.
Both parts are required. A one-person corporation where the owner makes every decision is not automatically an alter ego; that describes most small businesses. And a creditor who cannot collect is not automatically the victim of an inequitable result; an unpaid debt is the ordinary consequence of limited liability, not an exception to it. What courts look for is the combination: an entity run as the owner’s pocket, plus something about the way it was run that makes it unjust to let the owner walk away — assets stripped out, a shell left holding the liability, a creditor misled about who it was dealing with.
The factors courts look at
The unity-of-interest question is decided from the whole picture. Associated Vendors, Inc. v. Oakland Meat Co. (1962) 210 Cal.App.2d 825 collected the list that courts still use. The factors most often cited include:
- Commingling of funds and other assets, failing to keep the entity’s money separate, and diverting entity funds to non-business uses;
- Treating the entity’s assets as the owner’s own;
- Failing to keep corporate records or minutes, or to observe corporate formalities;
- Inadequate capitalization — starting or running the business with far less money than its obligations foreseeably required;
- Identical equitable ownership, and the same officers and directors, across two related entities;
- Using the same offices and employees, or holding one entity out as liable for the other’s debts;
- Using the entity as a mere shell or conduit for the owner’s or another entity’s affairs.
No single factor decides the question. Undercapitalization comes up so often that Associated Vendors addressed it squarely: thin capital is an important factor, but the court found no case holding that it alone requires piercing the veil. The strongest cases stack several factors; the weakest rest on one.
LLCs: the same doctrine, with one difference
The alter ego doctrine applies to LLCs. Corporations Code section 17703.04(b) says a member is subject to liability under the common law governing alter ego, under the same or similar circumstances and to the same extent as a shareholder of a corporation. An LLC owner who commingles funds or strips the company has the same exposure a shareholder would.
The one statutory difference concerns formalities. The same subdivision provides that the failure to hold meetings of members or managers, or to observe formalities about calling and conducting meetings, is not to be considered a factor tending to establish alter ego liability where the articles of organization or operating agreement do not expressly require those meetings. That is a genuine advantage for a small business that will never hold a formal meeting. It is not a pass on everything else: separate accounts, adequate capital, and honest dealing still count.
Reverse piercing: reaching the entity for the owner’s debt
Traditional piercing runs from the entity to the owner. Outside reverse veil piercing runs the other way: a creditor with a judgment against an individual asks the court to reach the assets of an entity the individual controls, on the theory that the entity is the individual’s alter ego, used to keep assets out of reach.
An earlier decision had rejected this remedy against a corporation. In Curci Investments, LLC v. Baldwin (2017) 14 Cal.App.5th 214, the Court of Appeal distinguished that case and held that reverse piercing is possible against an LLC, at least on facts like those before it: a judgment debtor who held 99 percent of an LLC that had distributed roughly $178 million to him and his wife before the judgment and nothing after it, while a charging order against his membership interest — the usual creditor remedy against an LLC member — produced nothing. The court sent the case back for the trial judge to decide whether the facts actually justified piercing. The remedy is fact-driven and far from routine.
Adding the owner after judgment, and why plaintiffs plead alter ego up front
A creditor who already holds a judgment against the entity does not always have to start over. Code of Civil Procedure section 187 gives a court the means necessary to carry out its jurisdiction, and California courts have long used it to amend a judgment to add a judgment debtor. The motion has to show more than alter ego, though. Because the new debtor never had a day in court, the creditor must also show that the person controlled the litigation and was virtually represented in it — that the entity’s defense was, in substance, theirs. NEC Electronics Inc. v. Hurt (1989) 208 Cal.App.3d 772 reversed an amended judgment on exactly that ground: the corporation had filed a bare denial and never appeared at trial, so there was no defense for its president to have controlled.
That is why a plaintiff with any reason to suspect an alter ego situation usually names the owner and pleads alter ego in the complaint. It puts the owner on notice, gets the issue tried on a full record, and avoids the extra hurdles of a post-judgment motion.
Keeping the veil intact: a checklist for owners
Most veil-piercing exposure comes from habits, not from one dramatic act. The habits that prevent it are not complicated:
- A separate bank account for the entity, with no personal expenses run through it and no business expenses paid from personal accounts without a paper trail;
- Adequate capital for the business you are actually running, and liability insurance sized to the risk;
- Contracts, leases, and invoices signed in the entity’s name, with your title, so the other side knows who it is dealing with;
- Owner loans, capital contributions, and distributions documented when they happen, not reconstructed later;
- The Secretary of State Statement of Information filed on schedule — annually for a corporation, every two years for an LLC — and the entity kept in good standing;
- For a corporation, minutes or written consents for the decisions that matter; for an LLC, an operating agreement that reflects how the company actually runs.
None of this excuses a personal promise or a personal wrong. What it does is keep the first half of the test — unity of interest — from being satisfied, which is where most veil-piercing claims are decided.
