Non-disclosure agreements (NDAs) are a frequent part of business in the United States, especially for startups, founders, and small business owners. Whether you are pitching a new idea, hiring a contractor, or exploring a partnership, you may be asked to sign an NDA. While these agreements are intended to protect confidential information, they can also create unexpected risks and obligations if you do not understand what you are agreeing to. Many founders sign NDAs without reviewing the details, thinking they are all standard. Others miss critical state law differences or hidden terms that could impact their business. This guide explains the key questions to ask before signing a non disclosure agreement, highlights common mistakes, and provides practical examples and checklists to help you make informed decisions.
What Is a Non-Disclosure Agreement?
A non disclosure agreement (NDA) is a legal contract that requires one or more parties to keep certain information confidential. NDAs are widely used in the US to protect sensitive business information, such as:
- Startup ideas and business plans shared with investors or partners
- Trade secrets and proprietary processes given to contractors or employees
- Financial data, customer lists, or marketing strategies discussed with vendors
- Product designs or software code revealed during collaborations
NDAs can be unilateral (one party discloses, the other receives and must keep it confidential) or mutual (both parties share and protect each other's information). The agreement usually defines what is confidential, how it can be used, and what happens if someone breaches the agreement.
There is no single federal law that governs all NDAs. The federal Defend Trade Secrets Act (DTSA) provides a baseline for trade secret protection, but most NDA rules and enforceability issues are determined by state contract law. This means the details of your NDA, and how it is enforced, can vary depending on which state's law applies. Some industries, such as healthcare or finance, may also have additional confidentiality requirements under federal or state regulations.
Key Questions to Ask Before Signing an NDA
Before you sign a non disclosure agreement, take time to review the terms carefully. Here are the most important questions to consider, along with practical examples:
- What information is covered? Is the definition of "confidential information" clear and specific? For example, does it cover only documents labeled "confidential," or does it include anything discussed in meetings? If the definition is too broad, you might be restricted from using your own ideas or information you already know. Ask for a list or examples of what is covered.
- Who is bound by the agreement? Does the NDA apply only to you, or does it also cover your employees, contractors, affiliates, or advisors? If you are a founder with a team, make sure everyone who might access the information is either covered by the NDA or has signed a separate agreement.
- How long does the obligation last? Is there a specific time period for confidentiality (such as two or three years after disclosure), or is it indefinite? Some states, such as California and Illinois, limit how long NDAs can last, especially for employees. Make sure the time period is reasonable for your industry and state.
- What are the permitted uses? Can you use the confidential information for any purpose, or only for a specific project or evaluation? For example, if you are reviewing a potential partnership, the NDA might limit you to using the information only for due diligence, not for developing your own competing product.
- What happens if there is a breach? Does the NDA specify remedies, such as injunctions (court orders to stop disclosure), monetary damages, or attorney fees? Are there penalties or limits on liability? Some NDAs require you to pay the other party's legal costs if you breach, which can be risky for small businesses.
- Which state law applies? Is there a governing law or jurisdiction clause? If the other party is in a different state, their laws may be very different from yours. For example, California law is generally more protective of employee mobility and less likely to enforce overly broad NDAs, while Texas or New York may enforce broader terms.
Asking these questions before signing can help you avoid surprises and ensure the NDA fits your business needs.
Example: Imagine you are a founder in New York discussing a potential partnership with a company in California. The NDA says California law applies and requires you to keep all information confidential forever. You should ask if the indefinite term is enforceable under California law and whether the definition of confidential information is too broad for your business activities.
Common NDA Mistakes and How to Avoid Them
NDAs are often treated as routine paperwork, but small mistakes can have major consequences. Here are some frequent errors US founders and operators make when signing NDAs, along with tips to avoid them:
- Signing without reading: Many people assume all NDAs are the same. In reality, terms can vary widely. Always read the entire agreement before signing, and do not hesitate to ask questions.
- Agreeing to overly broad definitions: If "confidential information" includes anything the other party says or writes, you may be restricted from using your own knowledge or independently developed ideas. Ask for a clear, specific definition and request exceptions for information you already know or develop on your own.
- Not checking the duration: Some NDAs last forever, while others have a set term. Indefinite NDAs can create long-term obligations that are hard to manage, especially if employees leave or your business pivots. Make sure the time period is reasonable for your industry and state.
- Ignoring state law differences: State laws can affect whether an NDA is enforceable, especially for employees or contractors. For example, California limits NDAs that restrict employees from working elsewhere or using general skills. Illinois and Washington have rules about maximum periods for confidentiality in employment. Always check which state law applies.
- Missing exceptions: Most NDAs have exceptions for information that is public, already known, or independently developed. If these are missing, you could be held liable for things you should not be. Make sure the NDA includes standard exceptions.
- Overlooking remedies and penalties: Some NDAs include harsh penalties or require you to pay the other party's legal fees. Understand what happens if there is a dispute and whether the remedies are fair and enforceable in your state.
- Failing to protect your own confidential information: If the NDA is one-way, make sure you are not giving up your right to protect your own information. Consider asking for a mutual NDA if both parties will be sharing sensitive details.
- Not considering practical enforcement: Even if the NDA is enforceable, will you be able to detect a breach or afford to pursue legal action? Consider whether the agreement is practical for your business size and resources.
To avoid these mistakes, use this NDA review checklist before signing:
- Review the definition of confidential information for clarity and specificity
- Check who is bound by the NDA (including employees, contractors, and affiliates)
- Confirm the duration of the agreement and whether it is reasonable for your state and industry
- Look for standard exceptions (public, already known, independently developed)
- Understand permitted uses and restrictions
- Review remedies, penalties, and limitations on liability
- Verify the governing law and jurisdiction
- Consider whether the NDA should be mutual
Example: A small business owner in Texas is asked to sign an NDA that defines confidential information as "all information disclosed, whether oral or written, regardless of whether it is marked confidential." This could prevent the owner from using knowledge gained from public sources or prior experience. The owner should ask for a narrower definition and standard exceptions.
State Law Issues: What Changes from State to State?
Because NDAs are governed mainly by state contract law, their enforceability and interpretation can change depending on where you and the other party are located. Here are some key state law issues to watch for:
- Employee NDAs: Some states, like California, limit or prohibit NDAs that restrict employees from working for competitors or using general skills and knowledge. California courts often refuse to enforce NDAs that go beyond protecting true trade secrets. In contrast, states like Texas or New York may enforce broader NDAs, as long as they are reasonable and not overly restrictive.
- Trade secret protection: The federal Defend Trade Secrets Act (DTSA) provides a baseline, but most states have adopted versions of the Uniform Trade Secrets Act (UTSA). However, states may differ on what counts as a trade secret and how it must be protected. For example, Massachusetts and Illinois have their own versions of the UTSA with unique requirements.
- Duration limits: Some states limit how long an NDA can last, especially in employment contexts. For example, Illinois limits confidentiality obligations for employees to a reasonable period after employment ends. Washington requires that NDAs with employees be reasonable in duration and scope.
- Remedies and penalties: Some states may not enforce penalty clauses or may limit the types of damages you can recover for a breach. For example, California generally does not enforce punitive damages for breach of contract, while New York may allow broader remedies if specified in the agreement.
- Public policy exceptions: States may refuse to enforce NDAs that are too broad, restrict whistleblowing, or violate public policy. For example, federal law prohibits NDAs from preventing employees from reporting certain types of misconduct to government agencies. Some states also restrict NDAs that cover harassment or discrimination claims.
Example: An employee in Illinois is asked to sign an NDA with a five-year confidentiality term after leaving the company. Illinois law may consider this excessive unless the information is a true trade secret. The employee should ask for a shorter term or clarification on what information is truly confidential.
Always check which state's law is listed in the NDA. If you and the other party are in different states, consider whether the chosen law is fair and whether you are comfortable resolving disputes in that state. If in doubt, ask for clarification or negotiate the governing law clause.
Checklist: State Law Red Flags
- Does the NDA restrict employees from working elsewhere? Check for non-compete language disguised as confidentiality.
- Is the duration reasonable for your state and industry?
- Are there exceptions for whistleblowing or reporting illegal activity?
- Does the NDA comply with state-specific rules for trade secrets?
- Are penalties or remedies enforceable under your state law?
If you are unsure, consider a legal review, especially for high-value deals or cross-state agreements.
When Should You Seek a Legal Review?
Not every NDA requires a full legal review, but there are situations where getting legal input can save you time, money, and risk. Consider seeking a review if:
- The NDA is part of a high-value deal or involves sensitive intellectual property, such as proprietary software, patents, or trade secrets
- You are being asked to agree to unusual or one-sided terms, such as unlimited liability or indefinite confidentiality
- The other party is a much larger company or has more bargaining power, making negotiation more challenging
- The NDA includes unfamiliar legal language or references to laws you do not recognize
- You have employees, contractors, or affiliates who will also be bound by the NDA, especially in multiple states
- The NDA references international parties or cross-border disclosures, which may trigger additional legal requirements
- The NDA covers regulated industries, such as healthcare, finance, or defense, where federal or state confidentiality rules may apply
Legal review can help you:
- Spot hidden risks or obligations, such as indemnity clauses or broad definitions
- Negotiate more balanced terms, including mutual protection and reasonable duration
- Ensure the NDA is enforceable in your state and industry
- Protect your rights if there is a dispute, including understanding the cost and process of enforcement
Example: A startup founder is negotiating with a large technology company that insists on its standard NDA. The agreement includes a clause requiring the founder to pay all legal fees if there is a dispute, regardless of outcome. A legal review can help the founder negotiate this clause or understand the risks before signing.
Even if you do not get a full legal review, consider using a template NDA that is tailored to your state and industry. Avoid copying NDAs from the internet without checking if they fit your situation. Many generic templates do not account for state law differences or industry-specific requirements.
Checklist: When to Seek Legal Help
- High-value or sensitive deals
- Unusual or one-sided terms
- Multi-state or international parties
- Regulated industries
- Unclear or confusing language
FAQs
Are NDAs enforceable in every state?
Most states will enforce NDAs if they are reasonable and do not violate public policy. However, some states, like California, have strict rules about what can be protected and may refuse to enforce NDAs that restrict employees or cover information that is not truly confidential. Always check the governing law and make sure the NDA complies with local rules.
What happens if someone breaches an NDA?
If a party breaches an NDA, the non-breaching party can seek remedies such as an injunction (to stop the disclosure), monetary damages, or sometimes attorney fees if allowed by the agreement. The exact remedies depend on the NDA terms and the law of the state that governs the agreement. Enforcement can be costly and time-consuming, so consider whether the remedies are practical for your business.
Can I refuse to sign an NDA?
Yes, you can refuse to sign an NDA, but the other party may choose not to share information or proceed with the deal. If you are uncomfortable with the terms, try negotiating for changes or ask for clarification. It is better to ask questions than to sign something you do not understand. If the NDA is a dealbreaker, consider whether the relationship is worth the risk.
Do NDAs cover information that is already public?
No, most NDAs exclude information that is already public, known to the receiving party, or independently developed without reference to the confidential information. Always check for these exceptions in the agreement. If they are missing, ask to add them before signing.
What is the difference between an NDA and a non-compete agreement?
An NDA is designed to protect confidential information, while a non-compete agreement restricts a party from working for competitors or starting a competing business. Some NDAs may include non-compete language, especially in employment settings, but these are subject to stricter state law rules. Always check for hidden non-compete clauses in NDAs and understand your state's laws on enforceability.
