Forming a corporation or limited liability company (LLC) helps protect your personal assets from business debts and lawsuits. This protection, known as the corporate veil, is not absolute. Courts look beyond formation documents to see how the business actually operates. If owners blur the line between personal and business affairs, Texas courts can, and do, pierce the corporate veil.
A Houston business lawyer can help you maintain the legal separation your business structure was designed to provide. Below, we outline nine common mistakes that can expose owners to personal liability.
When Texas Courts Will Pierce the Corporate Veil
Texas law usually shields owners from personal liability, but there are limits. In Castleberry v. Branscum, the Texas Supreme Court identified several situations where courts may disregard the corporate form, including when a business is used to commit fraud, evade obligations, or act as a personal extension of its owner.
Although Texas Business Organizations Code § 21.223, which typically requires proof of actual fraud for personal benefit, later narrowed Castleberry, the decision remains central to veil-piercing analysis. Courts still examine whether an entity truly operates as a separate business or merely serves as the owner’s alter ego.
1. Failing to Keep Personal and Business Finances Separate

- Paying company debts with personal checks or commingling funds
- Personally guaranteeing company obligations
- Diverting company profits for personal use
- Operating with inadequate capitalization
- Using the company for personal purposes
- Failing to maintain distinct assets and records
To avoid this, business owners should maintain separate bank accounts, document all transactions between the business and its owner, and avoid treating company funds as personal income. Courts view commingling as strong evidence that the owner disregarded the corporate boundary.
2. Missing or Improper Corporate Records
Although Texas LLCs have fewer formalities than corporations, they still require a certain level of structure and documentation. This can include:
- Company agreements
- Membership records and ownership interests
- Crucial decision documentation
- Minutes of important meetings or resolutions
Failure to maintain these records can suggest that the owner is not running the business as a legitimate entity. Even if the company is successful, the lack of documentation makes it vulnerable to disputes that may arise.
3. Underfunding the Business
If a company cannot pay debts or function without constant owner help, courts may find it undercapitalized. A business should have enough funding to operate on its own. Common red flags include:
- Company exists just to avoid liability
- Took on debts it couldn’t pay
- Owner kept assets out of the business
Texas courts consider whether your business had reasonable funding for its expected operations.
4. Using the Business to Commit Fraud
No corporate structure protects owners who intentionally use the business for wrongful or fraudulent conduct. Under Texas Business Organizations Code § 21.223, the corporate veil may only be pierced when an individual uses the corporation to perpetrate an actual fraud primarily for their direct personal benefit. Examples of improper uses include:
- Misrepresenting services or products
- Evading taxes
- Hiding assets
- Misleading creditors
- Breaching statutory or fiduciary duties
Older common law doctrines, such as Castleberry, sometimes allowed piercing merely for an alter ego or a sham entity, but Texas now requires actual fraud with personal benefit to pierce the veil.
5. Failing to Follow the Company Agreement, Operating Agreement or Bylaws

- Allowing unauthorized individuals to sign contracts
- Distributing profits in ways the agreement prohibits
- Changing ownership without written authorization
- Failing to follow voting or decision-making processes
Courts often examine whether the business followed its own rules. When the answer is no, it becomes far easier to pierce the corporate veil.
6. Treating the Business as a Personal Extension
The more the business appears to be an extension of the owner rather than an independent operation, the easier it is for a plaintiff to argue that the corporate veil should not apply. Warning signs include:
- No separate business office or address
- Lack of employees or defined roles
- Using personal property as business assets without documentation
- Having no distinction between the owner and the business identity
To maintain separation, the company must have its own distinct identity, including a unique branding, dedicated email domains, contracts in the company’s name, and clearly defined internal roles.
7. Ignoring Required Tax and Legal Filings
Even a properly formed and operated business can lose liability protection if it fails to:
- File annual franchise tax reports with the Texas Comptroller
- Maintain a registered agent and registered office
- Renew state or industry licenses
- Keep up with payroll, employment, or state tax obligations
Failing to stay current on state filings or taxes can cause an LLC or corporation to lose its legal standing, along with the protections offered under Texas Business Organizations Code §§ 101.113-.114. If that happens, owners could become personally liable for company actions until the business is reinstated.
8. Not Documenting Loans, Payments, or Internal Transactions
Every owner-to-business transaction should be recorded with clear terms. Missing documentation makes it look like the owner is taking money at will, weakening the corporate veil. Key transactions that must be documented include:
- Owner contributions and draws
- Reimbursements
- Member or shareholder loans
9. Letting Business Insurance Lapse
Insurance does not prevent a lawsuit, but it does help demonstrate that the business operates independently and responsibly. Operating without sufficient insurance can support claims of negligence or reckless disregard, which may factor into veil-piercing claims. In some industries, lack of insurance can itself be evidence of improper business operation.
Protecting Your Corporate Veil Requires Daily Awareness
Maintaining strong liability protections requires continuous separation, thorough documentation, and strategic adherence to legal compliance. Even one ongoing bad habit, such as using the business account to pay personal expenses, can be used as evidence to pierce the corporate veil.
