Is an LOI legally binding?

It depends on the language. An LOI can contain binding provisions (for example, confidentiality or exclusivity) while leaving the main commercial terms non-binding. To avoid unintended obligations, state clearly which clauses are intended to bind the parties.

Can I sign an LOI electronically?

Yes. Electronic signatures are legally valid under the ESIGN Act (15 U.S.C. ch. 96) and most state UETA laws, provided intent, consent, attribution, and record retention requirements are met.

Do I need a notary or witnesses?

Most LOIs do not require notarization or witnesses. If a state or specific counterparty requests notarization or if the LOI attaches documents that require notarization, follow the applicable notary rules.

What if the counterparty changes terms in a response?

Treat a modified LOI as a counteroffer. Document changes clearly, seek internal approvals, and avoid verbal amendments without written confirmation to prevent disputes.

Should counsel review the LOI?

Yes, especially for high-value or complex deals. Legal review helps ensure the LOI correctly captures intentions and limits unintended legal exposure.

How do I revoke or withdraw an LOI?

Unless the LOI contains binding commitments preventing withdrawal, you can revoke it in writing. If binding provisions exist, consult legal counsel to understand potential liabilities.

What a Business Letter of Interest Is and When It's Used

A Business Letter of Interest is a brief, formal document used to express preliminary intent to pursue a commercial opportunity — for example, a purchase, partnership, lease, or joint venture. It typically summarizes the parties, high-level terms, timelines, and any requested due diligence. The letter can be non-binding or contain limited binding provisions (confidentiality, exclusivity); it sets expectations and helps prioritize negotiations before drafting a definitive agreement. Parties often use an LOI to document mutual interest, outline next steps, and capture key commercial points to reduce misunderstanding.

Why a Business Letter of Interest Matters

A clear LOI signals intent, frames key commercial terms, and reduces negotiation friction while preserving flexibility for a later definitive agreement.

Who Typically Prepares and Signs an LOI

The LOI is used by deal initiators and counter-parties across industries to record initial terms and next steps before formal contracts.

Entrepreneurs and small-business owners seeking partners, buyers, or investors; used to document preliminary commercial terms and timelines.
Corporate development and M&A teams at mid-size and large companies to reserve negotiation priority and outline due diligence expectations.
Brokers, real estate agents, and commercial landlords using LOIs to summarize price, contingencies, and proposed closing schedules.

Core Parts of a Professional Business Letter of Interest

A well-structured LOI is concise and organized so parties can quickly confirm commercial alignment and proceed toward a definitive agreement.

Introductory Clause

Identify the parties, effective date, and the specific opportunity or asset that the letter addresses, using clear legal names.

Principal Terms

Summarize price, payment structure, key milestones, and any contingencies such as financing, inspection, or regulatory approvals.

Exclusivity Period

State whether the recipient must negotiate exclusively for a defined period and any carve-outs or termination conditions for exclusivity.

Confidentiality

Note any confidentiality obligations or reference an attached NDA; specify scope and duration of confidentiality protections.

Non-Binding Language

Specify which sections are non-binding and which (if any) are intended to be binding, such as confidentiality or exclusivity.

Next Steps

Outline desired timelines for due diligence, document drafting, approvals, and a target date to execute a definitive agreement.

Common Mistakes to Avoid When Preparing an LOI

Neglecting to secure internal authority, which can result in unsigned or unenforceable commitments later in the process.
Skipping basic confidentiality or exclusivity language when sensitive information is shared during due diligence.

Potential Consequences of an Incorrect or Misstated LOI

Unclear Intent: May produce disputed obligations

Undisclosed Contingencies: Can delay or derail closing

Unauthorized Signer: Risk of non-binding or void signature

Data Exposure: Inadvertent disclosure during diligence

Missed Deadlines: Loss of negotiation priority

Legal Costs: Increased attorney involvement and fees
