What Is a Letter of Intent (LOI) or Letter of Interest (IOI) — And Why Sellers Should Be Cautious
What Is a Letter of Intent (LOI) or Letter of Interest (IOI) — And Why Sellers Should Be Cautious
A Letter of Intent (LOI) is one of the most important milestones in selling a business. While it is generally considered a non-binding agreement, certain provisions—such as exclusivity and confidentiality—can carry legal obligations. Understanding what an LOI includes, when to sign it, and how to protect your interests can help you avoid costly mistakes and keep your transaction on track.
Is a Letter of Intent Legally Binding?
Not entirely—but some sections often are.
Most Letters of Intent are largely non-binding, but certain provisions commonly carry legal weight, including:
Exclusivity clauses
Confidentiality agreements
Good-faith negotiation requirements (in some cases)
Although an LOI may seem like a preliminary document, signing it can limit your flexibility during the sale process.
For example, an LOI may:
Prevent you from negotiating with other buyers during the exclusivity period.
Require you to protect a buyer's confidential information even if the transaction doesn't close.
Create legal disputes if certain binding provisions are violated.
Before signing, it's important to understand exactly which sections are legally enforceable.
Why Buyers Want an LOI
A Letter of Intent benefits buyers by allowing them to move the transaction forward while reducing uncertainty.
Common reasons buyers request an LOI include:
Securing an exclusivity period.
Demonstrating serious intent to lenders or investors.
Beginning formal due diligence.
Allowing time to obtain financing or internal approvals.
While these are reasonable objectives, sellers should be careful not to give up negotiating leverage too early.
What's Included in a Letter of Intent?
Although every transaction is different, most LOIs include:
Proposed purchase price or valuation methodology.
Asset sale or stock sale structure.
Due diligence timeline.
Exclusivity period.
Confidentiality provisions.
Expected closing timeline.
Financing or legal contingencies.
Identification of binding and non-binding provisions.
Every clause matters, so reviewing the document carefully is essential.
When Should You Sign an LOI?
A Letter of Intent should only be signed after several key items have been addressed.
Before signing, make sure:
You agree on valuation and overall deal structure.
The buyer has demonstrated financial capability.
You're comfortable with the exclusivity period and its terms.
An experienced business broker and attorney can help review these terms before you commit.
At Transworld Business Advisors, we connect sellers with experienced brokers, attorneys, CPAs, and other professionals to help protect their interests throughout the transaction.
Risks of Signing Too Early
Signing an LOI before you're ready can create unnecessary challenges, including:
Reduced negotiating leverage.
Exclusivity with an unqualified buyer.
Missed opportunities from competing buyers.
Legal exposure if binding provisions are violated.
Deal fatigue from lengthy negotiations that never close.
A lengthy exclusivity period can leave sellers negotiating with one buyer for months, only to have the deal fall apart while other opportunities disappear.
How to Protect Yourself Before Signing
Before executing a Letter of Intent:
Negotiate the terms rather than treating the LOI as a formality.
Keep exclusivity periods as short as practical.
Understand which provisions are legally binding.
Request proof of funds or financing milestones.
Work with experienced advisors throughout the process.
The right guidance can help you avoid unnecessary risk while preserving your negotiating position.
Can You Negotiate an LOI?
Yes—and you should.
A Letter of Intent is intended to begin negotiations, not end them. Sellers can negotiate:
Purchase price.
Payment structure.
Exclusivity period.
Due diligence timeline.
Contingencies.
Closing schedule.
Don't assume the first draft is the final agreement.
What Happens If an LOI Is Broken?
Although many portions of an LOI are non-binding, violating binding provisions—such as confidentiality or exclusivity—can result in legal disputes or reputational damage.
Depending on the language used, courts may also enforce certain obligations related to good-faith negotiations.
Aspect | Letter of Intent (LOI) | Purchase Agreement |
Purpose | Outline initial intentions | Finalize the deal and terms |
Level of detail | High-level, flexible | Comprehensive and detailed |
Legal enforceability | Limited—some binding provisions | Fully binding (or mostly) |
Timing | Early in the process | At or near closing |
Flexibility | Still negotiable | Locked in |
An LOI establishes the framework for negotiations, while the Purchase Agreement completes the transaction.
