Common Letter of Intent Mistakes That Create Contract Risk

For US founders, operators, and small business owners, letters of intent (LOIs) are a regular part of doing deals. Whether you are buying or selling a business, negotiating a joint venture, or lining up a major supplier, you may be asked to sign an LOI before moving forward. Many people assume these documents are just a formality or a way to "get on the same page." However, common mistakes in drafting, negotiating, or signing a letter of intent can create real contract risk. You might accidentally create a binding contract, expose your business to liability, or lose leverage in negotiations. This guide covers the most frequent letter of intent mistakes, explains how state law can change your risk, and provides practical steps to help you avoid costly surprises. We also include real-world examples, checklists, and answers to the most common questions US businesses have about LOIs.

What Is a Letter of Intent and Why Do Businesses Use Them?

A letter of intent is a document that summarizes the main terms of a proposed business deal. It is used early in negotiations to outline key points, clarify expectations, and set the stage for a more detailed contract. LOIs are common in mergers and acquisitions, business sales, joint ventures, real estate deals, supplier agreements, and other significant commercial transactions.

LOIs can serve several purposes, such as:

• Summarizing the main commercial terms (such as price, payment structure, and timeline)
• Establishing a period of exclusivity for negotiations
• Setting out confidentiality or non-disclosure obligations
• Clarifying what issues are still open for negotiation
• Providing a roadmap for due diligence or next steps

While LOIs are usually intended to be non-binding, the way they are written can make some or all of their terms legally enforceable. This is where many businesses run into trouble. If you are not careful, you may end up with obligations you did not intend or lose protections you thought you had. In some cases, an LOI can even be treated as a binding contract, leading to lawsuits or financial exposure if the deal falls apart.

Common Letter of Intent Mistakes That Create Contract Risk

Many US businesses make similar mistakes when dealing with LOIs. Here are some of the most frequent errors and why they project:

• Unclear Binding vs. Non-Binding Language: If the LOI does not clearly state which terms are binding and which are not, a court may find that the entire document is enforceable. For example, an LOI that says "the parties agree to the following terms" without a clear non-binding disclaimer can be treated as a binding contract in some states.
• Missing or Weak Exclusivity Clauses: If you want to prevent the other party from negotiating with competitors during a certain period, the LOI should include a clear and enforceable exclusivity provision. Otherwise, you may lose leverage or waste time and resources if the other party shops your deal around.
• Overlooking Confidentiality: Not all LOIs include adequate confidentiality clauses. If sensitive business information is shared during negotiations, you may have little recourse if the other party discloses or misuses it. A vague or missing confidentiality provision can leave your trade secrets unprotected.
• Failing to Address Key Deal Terms: Leaving out important terms like price, payment structure, deliverables, or conditions precedent can lead to confusion or disputes later. Even if the LOI is non-binding, unclear terms can create misunderstandings and weaken your negotiating position.
• Ignoring State Law Differences: Contract law is primarily governed by state law in the US. Some states are more likely than others to treat an LOI as binding, depending on its wording and the parties' conduct. Not understanding these differences can create unexpected risk.
• Assuming No Liability: Even if the LOI is mostly non-binding, certain provisions (like confidentiality or exclusivity) may be enforceable. Breaching these can expose your business to damages or legal action.
• Not Reviewing with Advisors: Many businesses sign LOIs without legal review, thinking it is "just a letter." This can lead to missing important issues or failing to negotiate better terms. Getting a professional review can help you avoid contract risk.
• Using Generic Templates: Relying on a one-size-fits-all LOI template without customizing it for your deal, industry, or state law can lead to gaps or conflicting terms. Templates may not reflect the unique risks of your transaction.
• Not Addressing Termination: Failing to specify how and when the LOI can be terminated can leave both parties uncertain about their rights if negotiations break down.
• Overcommitting in Negotiations: Making promises or taking actions that go beyond the LOI's terms can be used as evidence of intent to be bound, increasing the risk of a court enforcing the LOI as a contract.

These mistakes can result in lost deals, lawsuits, damaged relationships, or unexpected costs. Being proactive at the LOI stage is critical for protecting your business.

How State Law Affects Letters of Intent

There is no single federal law governing letters of intent. Instead, each state has its own contract law rules about when an LOI is binding and what obligations it creates. This means that the same LOI could be treated differently in California, Texas, New York, Illinois, or Florida.

Here are some important state law caveats:

• Intent and Language project: Courts look at the wording of the LOI and the conduct of the parties to decide if they intended to be bound. Even if the LOI says "non-binding," other evidence (such as emails or actions) can override this.
• Partial Binding Terms: Many states will enforce specific provisions (like confidentiality, exclusivity, or governing law) even if the rest of the LOI is non-binding. For example, a confidentiality clause may be enforceable even if the deal does not close.
• Good Faith Obligations: Some states, such as New York and Illinois, may find that signing an LOI creates a duty to negotiate in good faith. Breaching this duty can lead to liability for damages, even if no final contract is signed.
• Industry Practices: In certain industries (such as real estate or M&A), state law and industry custom may influence how LOIs are interpreted. For example, in New York real estate, LOIs are generally considered non-binding unless clearly stated otherwise.
• Choice of Law Clauses: Including a clause specifying which state's law applies can help provide clarity, but it must be drafted carefully to be effective. If the parties are in different states, this is especially important.

Because state law can make a big difference, it is important to understand the rules in the state where the deal is being negotiated or performed. If you are operating in multiple states, extra care is needed to avoid conflicting obligations. For example, a California court may be less likely to enforce an LOI as a binding contract than a Texas court, depending on the facts and wording.

Always consider the following:

• Where are the parties located?
• Where will the contract be performed?
• What does the LOI say about governing law and jurisdiction?
• What are the industry norms in your state?

Consulting with an attorney who understands the relevant state law can help you avoid surprises.

Checklist: What to Review Before Signing a Letter of Intent

Before you sign a letter of intent, take the time to review it carefully. Use this practical checklist to spot and address common risks:

• Clearly State Binding vs. Non-Binding Terms: Specify which provisions are binding (such as confidentiality, exclusivity, or governing law) and which are not. Use plain language and consider a separate section for binding terms. For example, "Except as otherwise stated, this LOI is non-binding."
• Define Key Deal Terms: Make sure the LOI covers the main commercial points, such as price, payment terms, deliverables, timeline, and any conditions that must be met before a final agreement. If a term is still under negotiation, state that clearly.
• Include Confidentiality Protections: If you will be sharing sensitive information, include a clear confidentiality or non-disclosure clause. Specify how long the obligation lasts, what information is covered, and any exceptions (such as information already in the public domain).
• Address Exclusivity (if needed): If you want to prevent the other party from negotiating with others, include a specific exclusivity or "no shop" provision. State how long it lasts, what it covers, and what happens if it is breached (such as a right to terminate or seek damages).
• Clarify Termination Rights: Explain how either party can withdraw from negotiations or terminate the LOI. This helps avoid disputes if the deal does not go forward. For example, "Either party may terminate this LOI by written notice to the other party."
• Specify Governing Law and Jurisdiction: Indicate which state's law will apply and where disputes will be resolved. This can help avoid confusion and forum shopping. For example, "This LOI shall be governed by the laws of the State of Delaware."
• Consider Good Faith Obligations: Be aware that some states may impose a duty to negotiate in good faith. If you want to limit this, state it clearly in the LOI. For example, "Nothing in this LOI shall create an obligation to negotiate in good faith beyond the express terms herein."
• Review with Advisors: Have a qualified attorney or advisor review the LOI before you sign, especially for high-value or complex deals. Professional review is especially important for business sales, mergers, or significant contracts.
• Customize for Your Deal: Do not rely solely on generic templates. Tailor the LOI to your specific transaction, industry, and state law requirements.
• Document Negotiations: Keep clear records of all negotiations, emails, and drafts. These can be important evidence if a dispute arises about what was intended.

Taking these steps can help you avoid the most common LOI mistakes and protect your business as you move forward.

Real-World Examples of Letter of Intent Pitfalls

To illustrate how letter of intent mistakes can create contract risk, here are some real-world scenarios US founders and operators have faced:

• Binding Deal by Accident: A startup in Texas signed an LOI to sell its assets. The LOI did not clearly state which terms were binding. When the buyer backed out, the startup sued for breach of contract. The court found the LOI was binding, and the startup was awarded damages. In Texas, courts may look beyond the document to the parties' intent and actions.
• Loss of Confidentiality: A SaaS company shared trade secrets during negotiations under an LOI that lacked a strong confidentiality clause. When talks broke down, the other party used the information to launch a competing product. The SaaS company had limited legal recourse because the LOI was vague. In California, trade secret laws may help, but clear contract terms are stronger.
• Exclusivity Dispute: A founder negotiating a joint venture included an exclusivity clause in the LOI but did not specify the duration. The other party started talks with a competitor after two weeks, claiming the exclusivity had expired. The founder lost leverage and the deal fell through. In New York, courts may enforce exclusivity only if the term is clear.
• State Law Surprise: A business based in California used a template LOI from a New York deal. The document did not specify governing law. When a dispute arose, the parties ended up in a lengthy fight over which state's law applied, adding cost and delay. This could have been avoided with a clear choice of law clause.
• Good Faith Negotiation Claim: In Illinois, a company signed an LOI to acquire a smaller business. When the buyer walked away, the seller sued for failure to negotiate in good faith. The court found that the LOI created a duty to negotiate, and the buyer was liable for the seller's costs. Illinois courts may impose good faith duties even if the LOI is mostly non-binding.
• Template Trouble: An e-commerce business used a generic LOI template found online to outline a supplier relationship. The template did not address exclusivity or governing law. When the supplier began selling to a competitor, the business had no recourse. The lack of tailored terms left the business exposed.
• Termination Confusion: Two parties negotiating a franchise agreement signed an LOI with no clear termination clause. When one party tried to withdraw, the other claimed damages for lost opportunity. The dispute dragged on, costing both sides time and money. A clear termination provision could have prevented this.

These examples show how small oversights in an LOI can lead to big legal and business consequences. Reviewing and customizing your LOI for each deal is essential.

FAQs

Is a letter of intent legally binding in the US?

It depends on the wording of the letter, the parties' intent, and state law. Some LOIs are entirely non-binding, while others include binding provisions (such as confidentiality or exclusivity). Courts will look at the language of the LOI, the conduct of the parties, and applicable state law to determine whether it is enforceable as a contract. Always clarify which terms are binding before signing.

What should I include in a letter of intent?

A well-drafted LOI should clearly state which terms are binding and which are not. It should outline the main commercial terms (such as price, timeline, deliverables), address confidentiality and exclusivity if needed, specify governing law, and explain how either party can terminate the LOI. If you are unsure, consider having an attorney review the document before signing.

Can I back out of a letter of intent?

Whether you can withdraw from an LOI depends on its terms and applicable state law. If the LOI is non-binding, you can usually walk away without penalty. However, if certain provisions (like confidentiality or exclusivity) are binding, breaching them can lead to liability. Always review the LOI carefully and clarify your rights before signing or withdrawing.

Do I need legal review for a letter of intent?

While not every LOI requires legal review, it is a good idea to have an attorney or qualified advisor review any LOI for high-value, complex, or sensitive deals. Legal review can help you spot risks, clarify terms, and avoid unintended obligations. This is especially important if you are dealing with parties in different states or industries with unique rules.

What happens if the parties act as if the LOI is binding?

If the parties begin performing under the LOI or act as if it is binding, a court may find that a contract exists, even if the LOI says it is non-binding. Conduct matters as much as the written document. Avoid taking actions that could be interpreted as acceptance of binding obligations until a final contract is signed.
