Illinois applies a two-prong veil-piercing test: unity of interest (evaluated through 11 factors from Jacobson v. Buffalo Rock) plus injustice or inequitable result. Illinois treats piercing as a remedy rather than an independent claim, and the Fontana v. TLD Builders framework reaches even non-shareholders who exercise equitable ownership and control. The breadth of who can be pierced makes documented governance separateness the primary defense for Illinois LLC owners.
Illinois’s Veil-Piercing Standard
Illinois applies a two-prong test that has been refined through decades of case law. The first prong is unity of interest — the entity is the alter ego of the individual or controlling entity. Courts evaluate this prong through the 11 factors set out in Jacobson v. Buffalo Rock Shooters Supply, Inc.: inadequate capitalization; failure to issue stock; failure to observe corporate formalities; nonpayment of dividends; insolvency of the debtor corporation; nonfunctioning officers and directors; absence of corporate records; commingling of funds; diversion of assets; treatment of corporate assets as the individual’s own; and the corporation as a mere facade for individual operations. The second prong asks whether adherence to separate entity status would promote injustice or inequitable circumstances.
Illinois treats veil piercing as a “means of imposing liability” rather than an independent cause of action — meaning a plaintiff must have an underlying claim against the entity, then can use veil piercing to reach the controlling person. Under Fontana v. TLD Builders (2005), the framework reaches even non-shareholders if they exercise equitable ownership and control, broadening the universe of people who can be held personally liable.
Illinois does not require actual fraud. The second prong is satisfied by injustice or inequitable circumstances — broader than fraud, and easier for plaintiffs to plead. That makes the first prong, where governance records do their work, the practical defensive line.
Real Cases from Illinois
Stockbridge 600 West Jackson, LLC v. Industrious National Management Co. LLC (Ill. App., 2023)
Veil pierced — parent liable for subsidiary’s lease
Industrious National created a subsidiary LLC to sign a Chicago office lease. When the lease underperformed, the subsidiary defaulted and claimed to have no assets. The Illinois Appellate Court found the subsidiary was a “mere instrumentality” with no independent existence: the parent had instructed movers to “wear plain clothing” and “be discreet” when secretly moving tenants to other locations; the parent had funds to pay rent but chose not to; and the subsidiary did not negotiate in good faith. The decision affirmed the trial court’s veil piercing and held the parent liable for the subsidiary’s lease obligations.
What governance records would have changed the outcome: The subsidiary had no independent governance — no separate decision-making, no documented authorization for the lease, no formal independence from its parent. Annual written consents establishing the subsidiary’s independent operations, banking resolutions documenting separate financial control, and single resolutions authorizing the lease in the subsidiary’s own name would have undermined the “mere instrumentality” finding directly. Each addressed one of the 11 Jacobson factors that drove the court’s analysis.

Fontana v. TLD Builders, Inc. (Ill. App., 2005)
Veil pierced — non-shareholder personally liable for $1.27M
TLD Builders contracted to build a $1.47 million home, then abandoned the project, leaving it incomplete and uninhabitable. The Illinois Appellate Court pierced the veil and held DiCosola — who was not a shareholder — jointly and severally liable for $1.27 million in damages. The court found he exercised equitable ownership and control over TLD, despite formal share ownership being elsewhere. The decision established that veil piercing in Illinois reaches anyone who dominates the entity, not just record-titled owners.
What governance records would have changed the outcome: Formal governance records separating DiCosola’s personal role from TLD’s corporate decisions would have undermined the “equitable ownership” finding. Documented board meetings, formal authorizations attributed to record-titled officers, and separation of personal and corporate decision-making would have made it harder to characterize him as the de facto controlling person. The case shows that in Illinois, the absence of formal records lets the court trace control through whatever pathway it finds.
How to Protect Your LLC in Illinois
Illinois’s 11-factor first-prong analysis rewards LLCs that produce documentary evidence on each factor. The list is long — absence of corporate records, commingling, undercapitalization, nonfunctioning officers, treatment of assets as the individual’s own — but the response is structural. Each factor has a corresponding governance document.
Annual written consents establish that the LLC has functioning officers making documented decisions on a regular cadence — addressing the “nonfunctioning officers” and “absence of corporate records” factors. Banking resolutions establish that financial authority flows from documented LLC governance, not from informal owner control — addressing the commingling and diversion factors. Distribution authorizations record that any money taken from the LLC was authorized through formal channels — addressing the “treatment as individual’s own” factor. Single resolutions document major decisions — addressing the formality factors directly.
Without these records, your personal assets are exposed under Illinois’s broad alter-ego analysis — and the Fontana framework means even the absence of formal share ownership won’t protect you if you exercise equitable control. Minutes.llc generates the governance documents Illinois courts examine, signs them with a digital corporate seal, hashes them, and stores them in a private offshore jurisdiction.

Frequently Asked Questions
Does Illinois require LLCs to keep meeting minutes?
Illinois LLC Act §1-40 requires LLCs to maintain certain records, but does not specifically mandate meeting minutes. Illinois courts evaluating veil piercing under the Jacobson v. Buffalo Rock 11-factor framework consider “failure to maintain corporate records” as one factor. The absence of governance documentation is treated as evidence of unity of interest under the first prong.
What is the standard for veil piercing in Illinois?
Illinois applies a two-prong test: (1) unity of interest such that the entity is the alter ego of the individual, evaluated through the 11 factors from Jacobson v. Buffalo Rock; and (2) adherence to separate entity status would promote injustice or inequitable circumstances. Illinois treats piercing as a “means of imposing liability” rather than an independent cause of action. Under Fontana v. TLD Builders, even non-shareholders can be held liable when they exercise equitable ownership and control.
Can a single-member LLC be pierced in Illinois?
Yes. Illinois courts apply the same Jacobson 11-factor analysis to single-member LLCs as to multi-member entities. Illinois has no statutory carve-out for single-member LLCs, and the broader Fontana framework reaches even non-shareholders who exercise control. Documented governance separateness is the primary defense for single-member LLC owners in Illinois.
What records protect an LLC from veil piercing in Illinois?
Illinois courts applying the 11-factor Jacobson test look for evidence of independent operation: separate bank accounts, formal authorization of major decisions, documented capital contributions, distribution authorizations, and annual written consents establishing officers and ratifying actions. The Stockbridge case shows that subsidiary entities without independent governance are characterized as “mere instrumentalities” — documented decision-making and separate banking are the direct response.
