Piercing of the Corporate Veil: STJ Reaffirms Asset Autonomy, But Companies Must Be Prepared to Prove It

The separation between a company’s assets and those of its partners is one of the pillars of modern corporate law. It is this very principle that enables the organization of economic activity, investments, the formation of corporate groups, and the legitimate assumption of risks inherent to business operations.

Recently, the Superior Court of Justice (STJ) reaffirmed this principle in its ruling on REsp 1873187/SP and REsp 1873811/SP. These cases addressed whether the corporate veil could be pierced based solely on the absence of attachable assets belonging to the debtor company or the potential irregular dissolution of its operations.

According to the legal thesis established under Repetitive Theme 1,210, in civil and corporate legal relationships, piercing the corporate veil requires actual proof of corporate abuse. This must be characterized either by a deviation of purpose or the commingling of personal and corporate assets, pursuant to Article 50 of the Brazilian Civil Code.

In other words: the mere absence of attachable assets or the irregular dissolution of a business entity are not sufficient grounds, on their own, to reach the personal assets of partners and directors.

Although this understanding is not exactly new, its reaffirmation is highly relevant for family businesses, holdings, economic groups, investors, M&A transactions, corporate reorganizations, and corporate structures involving multiple companies.

Asset Autonomy Remains Protected

In practice, the ruling reaffirms that piercing the corporate veil must remain an exceptional measure. It is not enough for a creditor to face difficulties in satisfying a claim, or for a company to have closed its doors irregularly, or to lack sufficient assets to fulfill a specific obligation.

To reach the assets of partners or directors, it remains mandatory to prove specific circumstances, such as:

• The use of the corporation to commit fraud or abuse of rights;

• A deviation from the company’s business purpose;

• The commingling of personal and corporate assets; or

• The improper use of the corporate structure to conceal assets.

The central takeaway for entrepreneurs and executives is: while asset autonomy is protected by the legal system, it must be reflected in the company’s day-to-day practices.

The formal existence of a legal entity, by itself, may not be enough to ward off future challenges if financial, corporate, and accounting management fail to show a clear distinction between assets. Simply put, the company must be fully capable of proving, through documentation, that this separation actually exists.

What Does the Ruling Mean for Partners, Directors, and Corporate Groups?

The established legal thesis brings welcome news: the STJ reinforces legal certainty for business activities and protects legitimate risk-taking.

However, it also serves as an important warning: companies that fail to maintain adequate records, mix personal and corporate expenses, perform financial transfers without formalization, or operate corporate structures without minimum governance standards may find themselves more exposed to litigation, requests to pierce the corporate veil, and disputes regarding asset liability.

Therefore, the protection of asset autonomy must be built preventively through practices such as:

• Strict separation between personal and corporate expenses;

• Proper documentation of operations between companies within the same group, including loans, cash advances, cost-sharing agreements, and related-party transactions;

• Regular bookkeeping that accurately reflects operational reality;

• Formalization of corporate resolutions and keeping corporate books and records fully updated; and

• Implementation of internal controls compatible with the size and complexity of the business.

The Impact on Holdings, Economic Groups, and M&A Transactions

This matter gains special relevance in more complex corporate structures.

It is common for economic groups to share resources, centralize cash management, perform related-party transactions, reorganize assets, or utilize holdings for asset protection, estate planning, or operational purposes.

These structures are entirely legitimate. The issue arises, however, when there is insufficient documentation to demonstrate the economic rationale, asset separation, and regularity of these intra-group operations from a corporate standpoint. In a potential judicial dispute, this lack of organization can build a favorable narrative for requests to pierce the corporate veil.

The topic also demands close attention in M&A transactions. Buyers, investors, and funds evaluate not only the tax, labor, civil, and regulatory liabilities of the target company, but also the quality of the corporate governance within the economic group it belongs to, and the potential risks arising from it.

A structure that cannot clearly demonstrate asset separation can be flagged as a significant risk factor during due diligence. For entrepreneurs looking to raise capital, sell equity stakes, reorganize a group, structure succession, or professionalize governance, this is a point that must be addressed well before any strategic transaction takes place.

The True Lesson for Companies

The legal thesis established under Repetitive Theme 1,210 delivers an important message to the market: asset autonomy remains a foundation of Brazilian corporate law and continues to be protected by the courts.

However, this protection should not be viewed as automatic. It must be sustained by documents, controls, accounting records, corporate practices, and decision-making processes capable of proving that the company is not an informal extension of its partners’ personal wealth.

Preventing risks associated with piercing the corporate veil is not merely a legal measure. It is a strategic decision for asset protection, business continuity, and value generation.

Companies with well-documented corporate structures, appropriate governance, and consistent internal controls are far better prepared to face disputes, attract investors, execute M&A transactions, access credit, implement succession plans, and preserve the assets of their partners and directors.
