New Jersey business owners sign contracts and agreements day in and day out. Routine paperwork like credit applications, supply agreements, equipment leases, and vendor terms are necessary to keep the business afloat. But what happens when they contain language designed to pierce the corporate veil and get to the owners’ personal assets?
It’s a sneaky, underhanded tactic that creditors may attempt. They slip in language intended to create a personal guaranty, making the signer personally responsible for the business’s debts if the business can’t pay. These issues often surface only after a dispute arises, which is why understanding how to resolve business disputes in New Jersey early can prevent escalation.
The tension reached a fever pitch in the 2025 NJ Supreme Court Case Extech Building Materials, Inc. v. E&N Construction, Inc. The case involved a supplier attempting to collect over $1 million in unpaid invoices directly from a business representative.
The Court’s ruling fundamentally changed how New Jersey handles personal guarantees and why consulting a business lawyer in NJ before signing credit documents matters more than ever.
Quick Answer: When Can a Business Owner Be Personally Liable for Debt in NJ?
Yes, but only if the creditor can prove that you clearly and unambiguously intended to be personally responsible for the debt. In its 2025 decision in Extech Building Materials, Inc. v. E&N Construction, Inc., the New Jersey Supreme Court ruled that simply signing a credit application as a corporate representative is not enough. To enforce a personal guaranty after Extech, the intent to be personally bound must be unmistakable.
What Is a Personal Guaranty in New Jersey Business Law?
A personal guaranty is a contractual promise by an individual to pay a business’s debt if the company fails to do so. It gives creditors the power to bypass the corporate veil and go after the owner’s personal assets. That could mean bank accounts, real estate, and other property.
Corporations and LLCs are designed to shield owners from liability, but a personal guaranty voluntarily sidesteps that protection. This is why disputes over guarantees frequently arise alongside actions to sue a business in New Jersey, especially when creditors are deciding whether to pursue the entity, the individual, or both.
Personal guarantees are legal under New Jersey law. But the courts treat them as serious financial commitments. Agreeing to one dramatically increases the risk a business owner incurs. That’s why the courts take a real microscope to guaranties, especially when they’re buried in the fine print of standard credit applications.
The New NJ Supreme Court Rule: “Unambiguous Intent” Is Required for Personal Liability
The controlling rule now comes from Extech Building Materials, Inc. v. E&N Construction, Inc. (2025). In that case, a supplier sought to hold a construction company’s representative personally liable based on a two-page credit application.
The Supreme Court rejected that attempt and established a clear rule: a personal guaranty is only enforceable if the individual knew and intended to be personally bound.
This ruling answered a question many business owners ask: does signing as president protect me from business debt in NJ? The answer is often yes, but only if the document itself does not clearly impose personal liability.
How New Jersey Courts Decide If You Personally Guaranteed a Business Debt
Under the Extech standard, New Jersey courts check many factors together.
The Signature Block
Did the individual sign as “John Smith, President” or just “John Smith”? Including a corporate title shows the signer is acting only as an agent of the entity, not in an individual capacity.
The Contract Language
Does the agreement explicitly state that the signer is personally guaranteeing the debt? Courts now reject vague or hidden language.
The Structure of the Document
Is the personal guaranty separated from the general credit terms, with its own signature line? This separation is critical when courts are looking at intent.
The Context of the Deal
Were there discussions indicating that personal liability was a condition of extending credit? Context matters when determining whether the signer knowingly assumed risk.
Many NJ business owners wonder whether signing a credit application automatically creates personal liability. After Extech, the answer depends entirely on whether the agreement clearly shows an intentional choice to assume personal responsibility.
Key Takeaways from Extech Building Materials, Inc. v. E&N Construction, Inc. (2025)
The Extech case has become the defining authority on personal guaranties in New Jersey.
In that dispute, the supplier attempted to collect more than $1 million directly from the business representative. Despite the size of the debt, the Court ruled that the guaranty was unenforceable because the signer did not clearly agree to personal liability.
For business owners, this decision offers meaningful protection against accidental exposure. For suppliers, it underscores why mistakes businesses make when collecting overdue invoices in New Jersey—especially unclear documentation—can derail enforcement efforts.
Does Signing as a Corporate Representative Protect You in NJ?
Often, yes.
Signing with your corporate title is one of the clearest ways to show that you are acting only on behalf of the business. It’s not a definitive form of protection, but the NJ Supreme Court recognizes it as a key indicator of intent.
Many owners assume the LLC structure alone is enough. In reality, careful signing practices are just as important as entity formation.
Protecting Yourself vs. Enforcing Debt After the Extech Ruling
The Extech decision changed the game for both sides of business transactions.
| For Business Owners | For Suppliers & Creditors |
| Always include your corporate title when signing | Use a separate, clearly labeled guaranty section |
| Strike language referencing personal liability | Require a second signature for the guaranty |
| Keep written records of negotiations | Make guaranty language bold and conspicuous |
| Ask for clarification before signing | Ensure the signer’s intent is unmistakable |
These distinctions now determine whether courts will enforce a personal guaranty in New Jersey.
How Creditors Can Enforce a Personal Guarantee in New Jersey
For creditors, enforcement now requires more than pointing to a signature.
To enforce a personal guaranty after Extech, a creditor must prove:
- Clear guaranty language
- A signature demonstrating personal assent
- Evidence that the guaranty was knowingly and intentionally accepted
Without these elements, courts are increasingly unwilling to impose personal liability. This often forces creditors to rethink strategy and avoid the kinds of missteps outlined in mistakes businesses make when collecting overdue invoices in New Jersey.
Why Business Lawyers in NJ Matter More for Credit Agreements After Extech
The new standard raises the bar for clarity and places more responsibility on business owners to understand what they are signing.
A business lawyer in NJ can:
- Review credit applications before execution
- Identify hidden personal liability clauses
- Defend owners facing improper guaranty enforcement
- Help suppliers draft enforceable guaranty language
For many companies, this explains why hiring a business lawyer in New Jersey early is far less costly than litigating after relationships break down.

If you are being asked to sign a credit application, facing a collection lawsuit, or unsure whether a document exposed you to personal liability, consulting a business lawyer in NJ can help protect your personal assets.
