An equitable doctrine permitting a court to disregard a corporation's separate legal personality when the entity functions as the mere instrumentality of its controlling shareholder. The doctrine requires proof of unity of interest and ownership between the corporation and its owner together with circumstances showing that adherence to the corporate form would sanction fraud or promote injustice.

Commingled Funds and Safety Neglect
Adrian Aguilar formed Avalon Pharmaceuticals as a single-purpose entity to run one research facility. He deposited all grant money into his personal account and paid facility repair bills from the same account. After a chemical spill injured a visitor, the facility had no assets left to satisfy the judgment. The court disregarded the corporate form because the commingling and undercapitalization showed Avalon existed only to shield Aguilar from personal liability.
Siphoned Construction Fees
Aaron Adams created Azure Solutions to build a single apartment complex. He caused the company to pay large monthly management fees directly to his wholly owned holding company, leaving Azure with no cash reserves. When the unfinished building collapsed and injured a worker, Azure could not pay the resulting judgment. The transfers demonstrated that Azure operated solely as Adams's instrumentality, allowing the worker to reach Adams's personal assets.

Separate Taxi Corporations
Alexandra Armstrong incorporated each of her ten cabs as a distinct corporation with minimal capital and no insurance. After one cab injured a pedestrian, the owning corporation held only a few thousand dollars. Because Armstrong had not used the separate corporations to defraud creditors or treat them as her personal alter egos, the court refused to pierce any veil and left the pedestrian limited to the corporation's meager assets.
Centralized Revenue Stripping
Alfred Ashford incorporated each of his retail outlets separately and routed every day's receipts to his central management company. One outlet's neglected wiring caused a fire that injured a customer. The outlet corporation was left insolvent. The pattern of systematic asset removal showed the outlet functioned as Ashford's alter ego, permitting the customer to reach both Ashford and the central entity.
Undocumented Personal Withdrawals
Aisha Ahmed formed Aurora Biotech to develop a single software product. She regularly transferred company funds to her personal brokerage account without any loan documentation or repayment. When the product failed and creditors sued, Aurora had no remaining assets. The undocumented transfers established that Aurora served as Ahmed's personal instrumentality, supporting disregard of its separate existence.
Informal Governance and Commingling
Angela Acosta formed Arcadia Retail to operate one store. She kept no separate ledgers, held no meetings, and paid personal travel expenses directly from the store account. After a slip-and-fall judgment exceeded the store's assets, the complete commingling and absence of any corporate records showed Arcadia was merely Acosta's alter ego, allowing the plaintiff to reach her personal assets.
Common questions
Frequently Asked
4
Does undercapitalization by itself justify piercing the corporate veil under the alter ego theory?+
No. Courts require additional evidence that the corporation was used to perpetrate fraud or operated as the shareholder's alter ego for personal benefit. Thin capitalization alone is insufficient to disregard the corporate form.
Supporting sources
What factors show unity of interest between a corporation and its owner?+
Relevant factors include commingling of funds, failure to maintain corporate formalities, undercapitalization, and systematic transfers of corporate assets to the owner or a related entity. These facts indicate the corporation lacks a separate personality.
Supporting sources
When does observance of the corporate form sanction injustice?+
Injustice arises when the corporation is left insolvent after the owner has extracted all value, leaving tort victims or creditors without any realistic recovery. The second prong is satisfied when the corporate fiction would shield the owner from liability created by his own domination.
Supporting sources
Can failure to observe corporate formalities alone support veil piercing?+
No. Modern statutes and case law expressly provide that failure to observe formalities is not a ground for imposing personal liability. Additional evidence of domination and injustice is required.
