Letter of Intent (LOI)
Published on: 19 Sep, 2025

In Singapore’s business world, negotiations often move faster than formal contracts. Parties want to outline terms, signal commitment, and begin due diligence—without yet drafting a full agreement. This is where a Letter of Intent (LOI) comes in.

An LOI is a preliminary document that sets out key terms of a potential deal. For business owners, it provides clarity during negotiations, aligns expectations, and can even reserve exclusivity. But it also carries risks if not carefully worded.

What Is a Letter of Intent (LOI)?

A Letter of Intent (LOI) is a written document expressing a party’s intention to enter into a business arrangement, such as:

  • Mergers & Acquisitions (M&A)

  • Joint Ventures

  • Franchise Agreements

  • Large Supply Contracts

  • Investment Deals

An LOI is typically non-binding, but may contain binding clauses such as confidentiality or exclusivity. It serves as a roadmap for formal contracts.

Key Features of an LOI

  1. Outline of Deal Structure: Purchase price, investment amount, equity split.

  2. Scope of Transaction: Assets vs shares, geographic coverage, duration.

  3. Conditions Precedent: Approvals required (board, regulatory).

  4. Due Diligence Provisions: Timelines and access to information.

  5. Confidentiality Obligations: Binding protection of sensitive data.

  6. Exclusivity Clauses: Prevents parties from negotiating with competitors for a set period.

  7. Timeline: Deadlines for signing definitive agreements.

LOI vs MOU vs Term Sheet

  • LOI: Signals intent, often used in transactions like acquisitions.

  • Memorandum of Understanding (MOU): Broader, used for partnerships or collaborations.

  • Term Sheet: Focuses on commercial and financial terms, especially in fundraising.

For Singapore SMEs, LOIs are common in business sales, joint ventures, and franchise deals.

Enforceability of LOIs in Singapore

Under Singapore contract law, LOIs are generally not binding unless they include specific binding clauses. Courts will assess:

  • Intention to Create Legal Relations: Did parties intend obligations to be binding?

  • Certainty of Terms: Are terms specific enough to enforce?

Binding clauses (e.g., confidentiality, exclusivity, governing law) are enforceable, while the overall deal terms are usually not.

Practical Business Scenarios

1. Business Acquisition

A Singapore SME issues an LOI to acquire a competitor. The LOI sets purchase price range and due diligence scope, while confidentiality and exclusivity clauses are binding.

2. Franchise Expansion

A local F&B brand provides an LOI to a potential master franchisee overseas. The LOI outlines territory, franchise fee expectations, and training support, subject to a full agreement.

3. Investor Negotiation

An angel investor issues an LOI to a startup, confirming intent to invest S$500,000 subject to due diligence. Exclusivity prevents the startup from shopping the deal around.

Case Study: LOI in Dispute

A Singapore construction company signed an LOI with a partner for a joint venture. The LOI was labelled “non-binding,” but contained binding exclusivity and confidentiality clauses. When the partner negotiated with a competitor during the exclusivity period, the company sued and won damages for breach of exclusivity—even though the joint venture itself never materialised.

Lesson: Specific LOI clauses can be binding even if the overall deal is not.

Benefits of Using an LOI

  1. Clarity in Negotiations: Sets a framework for discussions.

  2. Saves Time and Costs: Allows progress while detailed contracts are prepared.

  3. Secures Commitment: Exclusivity locks in serious interest.

  4. Enables Due Diligence: Provides access to confidential information under binding obligations.

  5. Reduces Misunderstandings: Clarifies key terms early, avoiding wasted effort.

Risks of LOIs

  1. False Sense of Security: Non-binding nature may leave parties without recourse if deal collapses.

  2. Ambiguous Drafting: Vague terms may cause disputes.

  3. Over-Commitment: Binding exclusivity may tie a party’s hands unnecessarily.

  4. Premature Disclosure: Sharing sensitive data before contracts are signed can be risky.

  5. Litigation Risk: Poorly worded LOIs may inadvertently create binding obligations.

Best Practices for Business Owners

  1. Mark Clearly: State which clauses are binding vs non-binding.

  2. Keep It Concise: Avoid over-detailing commercial terms unless necessary.

  3. Include Governing Law: Specify Singapore law for disputes.

  4. Set Timelines: Ensure deadlines for due diligence and contract signing.

  5. Limit Exclusivity: Keep periods short to preserve flexibility.

  6. Seek Legal Advice: Even though “preliminary,” LOIs can carry serious obligations.

Strategic Use of LOIs

  • Acquisitions: Lock in price ranges before committing to due diligence costs.

  • Franchises: Signal expansion intent before drafting franchise agreements.

  • Joint Ventures: Establish goodwill and clarify responsibilities.

  • Fundraising: Secure investor interest while negotiating detailed term sheets.

Conclusion: LOIs as Strategic Roadmaps

A Letter of Intent is not a full contract—but it is not meaningless either. For Singapore business owners, LOIs are strategic roadmaps that guide negotiations, secure key protections, and create a framework for successful deals.

Used wisely, LOIs:

  • Align expectations.

  • Protect sensitive information.

  • Provide negotiating leverage.

But they must be drafted carefully to avoid unintended obligations. With the right balance, LOIs can help businesses move from intention to execution with confidence.
