Letter of Intent vs Contract: When Each One Applies
A letter of intent signals that both parties intend to enter an agreement. A contract creates that agreement. The LOI outlines key terms both sides expect to formalize. The contract makes those terms binding. Confusing the two creates risk: treating an LOI as binding when it is not, or treating a contract as preliminary when it is already enforceable.
| Letter of Intent | Contract | |
|---|---|---|
| Primary purpose | Signal mutual interest and outline expected terms | Create enforceable obligations between the parties |
| Legally binding | Generally non-binding, except for specific clauses like confidentiality | Fully binding and enforceable from execution |
| Level of detail | High-level terms, often with gaps to be negotiated | Comprehensive terms covering all material aspects of the relationship |
| When it is used | Before the definitive agreement, to align on key terms | When terms are finalized and both parties are ready to commit |
| Typical context | M&A, real estate, large partnerships, complex multi-party deals | Any engagement where enforceable obligations are needed |
What is the difference between a letter of intent and a contract?
A letter of intent is a preliminary document. It says both parties intend to do business together and outlines the terms they expect to agree on. It is not, in most cases, a binding commitment. A contract is a definitive agreement. It creates obligations that both parties must fulfill, with consequences if they do not. The letter of intent is a handshake on direction. The contract is the enforceable commitment that follows. The confusion arises because some LOIs contain binding provisions, such as exclusivity or confidentiality, even while the rest of the document is non-binding.
When should you use a letter of intent?
Use a letter of intent when the deal is complex enough that both parties need to agree on major terms before investing in the time and cost of drafting a full contract. This is standard in acquisitions, real estate transactions, and large-scale partnerships. The LOI reduces the risk of spending weeks negotiating a contract only to discover that the parties disagree on a fundamental term like price, timeline, or exclusivity.
- The deal involves significant due diligence or legal costs before closing.
- Both parties want to confirm alignment on price and structure before drafting a contract.
- Exclusivity is needed during a negotiation period.
- The transaction is large or complex enough to justify a preliminary step.
When should you skip the LOI and go straight to a contract?
Skip the LOI when the terms are straightforward enough to go directly into a binding agreement. For most service engagements, consulting projects, and freelance work, a letter of intent adds a step without adding clarity. The proposal serves the preliminary alignment function, and the contract formalizes it. Adding an LOI between them creates an extra document without reducing risk.
- The engagement is simple enough that a contract can be drafted quickly.
- Both parties already agree on scope, price, and timeline.
- The cost of negotiation is low relative to the value of the engagement.
- A proposal already serves the alignment function the LOI would provide.
Can a letter of intent be binding?
Parts of it can be. Most LOIs include a statement that the document is non-binding, but carve out specific provisions that are binding. Common binding provisions include confidentiality, exclusivity, and the obligation to negotiate in good faith. The risk is ambiguity. If the LOI does not clearly state which provisions are binding and which are not, a court may interpret the entire document as binding if the terms are sufficiently definite. Every LOI should include explicit language about which sections create obligations.
What are the risks of using an LOI incorrectly?
The two main risks are treating a non-binding LOI as a commitment, and accidentally creating a binding agreement when you intended a non-binding one. The first risk leads to wasted time and broken expectations when one party walks away. The second risk leads to unintended obligations that a court may enforce. Both risks are managed by clear drafting. State which provisions are binding, include a termination mechanism, and specify that the LOI expires if a definitive agreement is not executed by a stated date.
Which one should you use?
Use a Letter of Intent when
- The deal requires significant due diligence before a contract is practical.
- You need exclusivity during a negotiation period.
- Both parties want to align on major terms before investing in legal drafting.
- The transaction is large, complex, or involves multiple parties.
Use a Contract when
- The terms are agreed and both parties are ready to commit.
- The engagement is simple enough that a preliminary document is unnecessary.
- You need enforceable obligations from the start.
- A proposal already provided the alignment that an LOI would offer.
FAQ
What is the difference between a letter of intent and a contract?
A letter of intent outlines the terms both parties expect to formalize in a binding agreement. A contract creates that binding agreement. The LOI is typically non-binding except for specific carved-out provisions. The contract is fully enforceable.
Is a letter of intent legally binding?
Most LOIs are non-binding by design, but they often contain specific binding provisions such as confidentiality, exclusivity, or good-faith negotiation obligations. The document should clearly state which provisions are binding and which are not.
Do I need a letter of intent before a contract?
Not always. An LOI is most useful when the deal is complex enough that both parties benefit from aligning on major terms before drafting a full contract. For simpler engagements, going directly to a contract is more efficient.
What happens if a letter of intent expires?
If the LOI expires without a definitive agreement being signed, neither party is obligated to proceed. Any binding provisions, such as confidentiality, typically survive the expiration. The parties can negotiate a new LOI or walk away.
