California Letter of Intent (LOI) FAQ

What is a Letter of Intent?

A Letter of Intent (LOI) is a document that outlines the initial terms and intentions of parties who plan to enter into a formal agreement. It is often used as a pre-contract to show serious interest and confirm the key points before drafting a final, legally binding contract.

An LOI helps ensure both sides agree on the main expectations, goals, and basic terms upfront, reducing misunderstandings later. While it may include important details such as pricing, timelines, responsibilities, and next steps, most Letters of Intent are not legally binding, except for specific clauses like confidentiality or exclusivity if included.

When to use a Letter of Intent?

A Letter of Intent (LOI) is used when two parties want to outline the key terms of a potential agreement before creating a formal contract. It helps confirm interest, clarify expectations, and make sure both sides agree on the main points early in the process.

Individuals often use an LOI when applying for a job, internship, school, or partnership opportunity to show serious intent and professional interest. Businesses use a Letter of Intent during negotiations for major transactions, such as buying a business, forming a partnership, or entering into a commercial agreement. In these cases, an LOI sets out the main terms — such as price, timeline, responsibilities, and confidentiality — before preparing a detailed and legally binding contract.

What should be included in a Letter of Intent?

A Letter of Intent (LOI) allows parties to outline, clarify, and announce the key terms of a potential deal before creating a final, legally binding agreement. It sets expectations and ensures both sides understand the proposed transaction.

A well-structured Letter of Intent should include:

• Contact information: Include the names, addresses, and contact details of both the sender and recipient.

• Salutation: Use a professional greeting and the recipient’s full name (e.g., “Dear [Name]”).

• Introduction: Clearly state the purpose of the letter, the opportunity or transaction being proposed, and the key parties involved.

• Body content: Provide essential details such as the scope of the proposal, responsibilities of each party, timeline, pricing or financial terms, contingencies, and any due diligence information required.

• Confidentiality or exclusivity (if applicable): Note any terms that limit sharing information or negotiating with others.

• Closing statement: Explain the next steps to move forward (such as signing the LOI) and include an expiration or response deadline.

• Signature: The sender should sign and date the LOI to confirm the intent.

• Enclosures: List and attach any supporting documents, such as NDAs, business summaries, or product details.

While an LOI is often not fully legally binding, businesses should consider having it reviewed by a lawyer to ensure clarity, protect their interests, and avoid unintended legal obligations.

Is a Letter of Intent legally binding?

A Letter of Intent is usually not fully legally binding, but it can include certain binding provisions depending on how it is written. Most LOIs simply outline the parties’ intentions and key terms before drafting a final agreement. However, specific sections — such as confidentiality, exclusivity, non-disclosure, or governing law clauses — can be legally enforceable if clearly stated as binding. To avoid misunderstandings, the LOI should clearly specify which parts are binding and which are non-binding.

What is the difference between a Letter of Intent and a Memorandum of Understanding (MOU)?

A Letter of Intent (LOI) and a Memorandum of Understanding (MOU) are both preliminary documents used before signing a formal contract, but they serve slightly different purposes. An LOI typically expresses one party’s intention to enter into a future agreement and often outlines key terms from a more one-sided perspective (usually the proposing party). It may include binding or non-binding sections, but it is generally more informal and focused on showing commitment to move forward.

An MOU, on the other hand, is usually more detailed and mutually drafted, outlining expectations, roles, and responsibilities of all parties involved. It is more formal than an LOI and is typically used when both parties want to document mutual understanding and cooperation before creating a legally binding contract. While both can be partially enforceable depending on their wording, an MOU is often viewed as closer to a contractual agreement than an LOI.

In short, an LOI expresses intent, while an MOU establishes mutual understanding and agreed-upon principles before finalizing a contract.
