Yes, while LOIs are generally non-binding, certain clauses within them—for example, confidentiality or exclusivity provisions—can be legally enforceable if clearly stated.

A Letter of Intent is typically 1–3 pages, depending on the complexity of the deal. It should be long enough to outline the key business terms, responsibilities, and next steps, but not so detailed that it starts to function like a full contract. The goal is clarity and alignment—not exhaustive legal drafting.

A Cover Letter accompanies documents (like proposals or applications) and simply introduces the sender, purpose, and key highlights.
 A Letter of Intent, on the other hand, expresses preliminary agreement between parties before drafting a formal contract.

  • Use a Cover Letter to present or summarize information.
  • Use a Letter of Intent to outline deal terms before negotiations begin.

A Letter of Intent (LOI) signals that parties intend to move forward with a specific agreement, often including draft terms and timelines.
 A Letter of Interest simply indicates interest in exploring a potential opportunity, without committing to terms.

  • Letter of Interest = initial interest
  • Letter of Intent = agreement on high-level deal terms and next steps

Both documents express preliminary agreements, but MOUs tend to be less formal and have more limited legal effect. LOIs are often more detailed regarding deal terms and are common in commercial transactions.

Not always. Simple transactions may proceed directly to the definitive contract. However, LOIs help in complex deals by outlining negotiation scope and protecting interests during preliminary stages.

It depends on the deal’s nature. Financial terms often appear in the LOI to ensure mutual understanding but can be subject to due diligence and final contract negotiation.

If the LOI is non-binding, breach usually does not lead to legal penalties, except if binding clauses like confidentiality are violated. However, breaches can harm trust and negotiation progress.

A universal template provides a strong starting point, but customization is vital to address industry-specific risks, jurisdictional requirements, and deal particulars.

A Letter of Intent typically ends with a clear closing statement that reaffirms the intent to move forward and outlines what happens next. The closing should:

  • Restate the shared goal (e.g., to finalize a definitive agreement).
  • Confirm any immediate next steps (such as due diligence or negotiation timelines).
  • Clarify which provisions are binding (commonly confidentiality, exclusivity, or governing law).

Most LOIs close with a simple, professional sign-off such as:

“We look forward to working together to finalize the agreement.”

Then include signature blocks for both parties. This ensures the document ends with mutual acknowledgment and clarity, without implying commitments beyond what the LOI is intended to cover.
