Structuring a Holdco So a Lawsuit Against One Subsidiary Can't Reach the Others

The whole point of using a holding company with separate subsidiaries is containment. If each risky activity or asset (a rental property, a product line, a piece of equipment) sits in its own LLC, then a lawsuit arising from that activity is supposed to stay contained inside that one LLC, rather than spreading to the parent company or to sister subsidiaries.

But that containment is not automatic just because you filed separate Articles of Organization for each entity. Courts will disregard the separate legal existence of commonly owned companies, and treat them as one enterprise for liability purposes, if they were never actually operated as separate businesses. This article covers what it actually takes to keep that wall standing.

It helps to separate two distinct protections that a holding company structure provides, because they work differently and fail for different reasons.

Inward protection (also called charging order protection) keeps a member's personal creditors from reaching the LLC's assets and business. This is the asset protection Wyoming is known for, and it's a matter of Wyoming's LLC statute.

Outward protection is the opposite direction: keeping a judgment against one subsidiary from reaching the parent company or its sister subsidiaries. This is governed by ordinary corporate law, specifically the doctrine of piercing the corporate veil, and its sibling doctrines of alter ego liability and enterprise liability (sometimes called the "single business enterprise" theory) when the target is a group of commonly owned companies rather than an individual owner. This article is primarily about the outward direction, because that's the one owners tend to overlook.

Veil piercing and enterprise liability claims are fact-intensive, and no single factor decides a case. But the factors courts repeatedly examine when deciding whether to treat separately formed companies as one enterprise include:

• Commingling of funds and assets between the parent and its subsidiaries, or between sister subsidiaries, is one of the factors courts cite most often as evidence the companies were never really separate.
• Undercapitalization, meaning a subsidiary was never given enough capital or insurance to cover the risks of the business it was formed to run.
• Disregard of corporate formalities, such as never documenting member decisions, never keeping separate books, or never executing a real operating agreement for the subsidiary.
• Holding the companies out as one business, for example sharing a name, marketing, office, phone number, or employees in a way that leads the public (and, later, a court) to see one business rather than several.
• Guarantees and cross-obligations, where the parent personally guarantees a subsidiary's debts or a subsidiary's assets are pledged for another subsidiary's financing, which can itself become the very link a creditor uses to reach across entities.

None of these factors is automatically fatal by itself, but they compound. A company with one sloppy habit is unlikely to lose its separateness in court; a company with several of them, especially commingled funds plus undercapitalization, is the fact pattern that shows up in the cases where courts do pierce.

1. Form each subsidiary as its own real LLC

Each subsidiary should have its own Articles of Organization, its own EIN, and its own registered agent record, not simply exist as a "DBA" or division of the parent. See our guide to Articles of Organization for what's involved in forming each one.

2. Give each subsidiary its own bank account and books

This is the single most-cited factor in veil piercing cases. Each subsidiary needs its own bank account, its own bookkeeping, and its own tax filings. Money moving between the parent and a subsidiary, or between two subsidiaries, should be documented as a loan, distribution, or capital contribution, not simply moved informally because it's "all the same money" to the owner.

3. Capitalize (or insure) each subsidiary for the risk it carries

A subsidiary that owns a risky asset, such as a rental property with tenants, needs enough capital or liability insurance behind it to plausibly cover the risks of that activity. An empty shell holding a valuable, high-risk asset with no insurance is a common fact pattern plaintiffs' attorneys look for.

4. Put intercompany dealings in writing, at arm's length

If the holding company charges a subsidiary a management fee, leases it equipment, or licenses it a name or trademark, paper it as you would with an unrelated third party: a signed agreement, a market rate, and an actual paper trail of payment. This is also where a properly drafted operating agreement for the parent-subsidiary relationship matters; see our companion article on operating agreement language for a parent LLC owning subsidiary LLCs for the specific provisions to include.

5. Be careful with guarantees and cross-collateralization

A lender may ask the parent to guarantee a subsidiary's loan, or ask for a subsidiary's assets as collateral for another subsidiary's financing. These arrangements are common and not inherently fatal to your structure, but they create a real, documented financial link between entities. Limit them to what the lender actually requires, and don't create voluntary cross-guarantees between subsidiaries just for convenience.

6. Hold each subsidiary out as its own business

Separate contracts, separate invoices and, where practical, separate insurance policies in each subsidiary's own name reinforce that each one is a real, independent business rather than a label on the parent's operations.

7. Document decisions instead of running everything informally

When the holding company, acting as the sole member or a controlling member of a subsidiary, makes a major decision (a distribution, a sale of the subsidiary's asset, a new loan), write it down as a member or manager action under the subsidiary's own operating agreement. Informality is inexpensive until it becomes Exhibit A in a piercing claim.

A typical setup looks like this: a Wyoming holding company sits at the top and owns 100% of each subsidiary LLC beneath it. The holding company doesn't operate a business, sign leases, or hold a risky asset directly; it just owns the membership interests in the subsidiaries. Each subsidiary owns and operates one discrete asset or activity, and each has its own bank account, its own books, and its own operating agreement. For a walkthrough of the parent/subsidiary/affiliate terminology used throughout this structure, see What's a Subsidiary?

This is also why real estate investors with multiple properties are typically advised to put each property in its own LLC beneath a single holding company, rather than in one LLC together; see should each rental property have its own LLC for that decision in more depth.

A Series LLC is sometimes pitched as a cheaper way to get the same isolation, since each series is intended to be shielded from the liabilities of the other series under a single master LLC. It can work, and it's popular with real estate investors for exactly that reason. The tradeoff is that series LLC liability shields are a newer legal concept with far less courtroom history behind them than the parent-subsidiary structure described above, and not every state recognizes or respects series LLCs formed elsewhere. See our full comparison of a Series LLC and a holding company before deciding which fits your situation, and our page on holding company vs. parent company terminology if you're unsure how the pieces relate.

Isolating liability between subsidiaries is less about the initial filing and more about how the group is run afterward.
