Piercing the Corporate Veil in California

By Ingrid Rainey · June 10, 2026 · 7 min read

Owners form an LLC or corporation for one primary reason: to keep business liabilities away from personal assets. California courts will disregard that separation when the entity is treated as the owner's alter ego and honoring the separation would sanction a fraud or produce an inequitable result. Both halves of that test matter, and the evidence courts rely on is mundane — bank records, meeting minutes, capitalization, and whether the company was ever really run as a company.

Key takeaways

California applies a two-part alter ego test: unity of interest between owner and entity, plus an inequitable result if the separation is respected.
Commingled funds and paying personal expenses from the business account are the fastest route to personal exposure.
Inadequate capitalization at formation is weighed heavily, especially in a business with known risk.
Reverse veil piercing is also available in California against LLCs, letting a creditor reach entity assets for an owner's personal debt.

The test courts actually apply

Part one is unity of interest and ownership — whether the separate personalities of the owner and the entity no longer really exist. Part two asks whether treating the acts as those of the entity alone would produce an inequitable result. Neither is satisfied by a single fact; courts weigh a long list.

This matters procedurally too. Alter ego is generally pleaded and proven in the underlying case, and it can also be raised after judgment through a motion to add a judgment debtor. An owner who assumed the case was 'against the company' can find themselves personally on the judgment.

The factors that show up in the findings

Commingling of funds — personal expenses paid from the business account, or the reverse.
Failure to maintain minutes, resolutions, and other corporate records.
Undercapitalization measured against the foreseeable risks of the business.
Identical equitable ownership across entities, with assets shuffled between them.
Using the entity as a mere shell or conduit for a single owner's affairs.
Failure to issue stock or membership interests, or to observe formalities the governing documents require.
Diversion of assets away from creditors to the owner.

Housekeeping that preserves the shield

Keep a dedicated business bank account and never run personal charges through it. Pay yourself through documented distributions, salary, or draws rather than ad hoc transfers. Sign contracts in the entity's name with your title, so counterparties are dealing with the company and know it.

Maintain the records: annual meeting minutes or written consents, an updated operating agreement or bylaws, current Statements of Information, and documented approval of major transactions. Any loan between the owner and the company should be papered with a note, a rate, and an actual repayment history.

Capitalization and insurance

A business that opens with no capital and no insurance in a line of work with obvious risk is the classic undercapitalization fact pattern. Fund the entity adequately at formation and document the contributions.

Insurance functions as practical protection even where the shield holds. A general liability policy, employment practices coverage, and professional liability where relevant often resolve the matter before an alter ego theory ever gets tested.

Where the shield never applied in the first place

Personal guaranties on leases, credit lines, and vendor accounts — contractual, and unaffected by the entity.
Your own tortious conduct; forming an entity does not immunize the person who committed the act.
Unpaid payroll taxes, where responsible-person liability reaches individuals directly.
Certain wage and hour claims, where California law permits individual liability for owners, officers, and managing agents who violate specific provisions.

Frequently asked questions

Does a single-member LLC get less protection in California?

The statute does not remove protection for single-member LLCs, and California law states that failure to hold meetings is not itself grounds for piercing. In practice single-member entities draw more scrutiny because commingling is easier and formalities are more often skipped.

Can a creditor reach my LLC's assets for a personal judgment against me?

Potentially. California recognizes reverse veil piercing against LLCs, and a creditor can also obtain a charging order against your membership interest.

How much capital is enough?

There is no fixed figure. Courts measure capitalization against the reasonably foreseeable risks of the specific business, which is why insurance is part of the answer.

If I already commingled funds, is it too late?

No. Correcting the practice, documenting reimbursements, and restoring formalities going forward reduces the exposure — and the history is only one factor among many.
