A letter of intent is a preliminary written agreement that captures the main terms two parties have negotiated before they commit to a binding contract. It shows up in business sales, real estate deals, joint ventures, job offers, and graduate school applications. The purpose is the same across all of them: pin down what both sides have agreed to so far while leaving room to work out the details. What belongs inside varies sharply by situation, and getting the structure wrong can lock you into a deal you thought was still tentative.
When a Letter of Intent Is Legally Binding
Most people assume every letter of intent is non-binding. That assumption gets expensive when a court disagrees. The general rule is that an LOI is not a final contract, but courts have repeatedly held that an LOI becomes enforceable when it contains all the material terms of a deal and lacks an express statement reserving the right to walk away before a formal agreement is signed. If the document uses mandatory language like “shall” and “will” throughout, specifies the price, parties, and key obligations, and never says the letter is non-binding, a judge may treat it as the deal itself.
To keep an LOI non-binding, state clearly that neither party is legally obligated unless and until a definitive agreement is signed. Avoid classic contract language like “offer,” “accept,” “agree,” and “commit.” Phrases like “presently intends” or “expects” signal that the parties are still negotiating. A termination clause allowing either side to end discussions at any time without liability reinforces that intent.
Even a non-binding LOI usually contains a few provisions written to be enforceable on their own. Confidentiality clauses protect sensitive information exchanged during negotiations. Exclusivity or “no-shop” clauses prevent the other side from entertaining competing offers for a set period, typically 30 to 90 days. When binding and non-binding provisions sit in the same document, the LOI should explicitly identify which sections carry legal weight and state that everything else does not. Skipping that distinction is where most disputes start.
Letter of Intent, Memorandum of Understanding, and Term Sheet
These three documents cover similar ground but suit different situations, and the names get swapped around when they shouldn’t be.
A letter of intent is most common in mergers, acquisitions, and commercial contracts. It is typically drafted by the buyer and sent to the seller for review and countersignature. It covers deal structure, purchase price, payment terms, transition arrangements, non-competes, and due diligence timelines. LOIs work best when one party is driving the negotiation.
A memorandum of understanding serves the same function but is drafted neutrally when both parties have roughly equal bargaining power. An MOU is circulated unsigned, negotiated collaboratively, and then signed by both sides. If you’re the seller opening dialogue, or the discussions feel genuinely mutual, an MOU signals that better than a buyer-drafted LOI.
A term sheet is standard in venture capital, private equity, and other financing transactions. Term sheets use a concise, often bulleted format to outline economic and control terms: valuation, investment amount, price per share, liquidation preferences, board composition, and investor protections. They work well when the terms are relatively standardized and speed matters more than narrative.
All three typically include binding provisions for confidentiality, exclusivity, and expense allocation, even when the core deal terms remain non-binding. The choice between them is less about legal effect and more about tone, context, and who is driving the conversation.
Business Acquisition Letter of Intent
An acquisition LOI needs to resolve one threshold question before anything else: is this an asset purchase or a stock purchase? An asset purchase lets the buyer pick which items to acquire (equipment, inventory, intellectual property, customer lists) while leaving behind liabilities the buyer doesn’t want. A stock purchase transfers the entire legal entity, including every debt, pending lawsuit, and tax obligation the company carries. That distinction drives every other term in the document.
Core Deal Terms
The LOI should state the proposed purchase price, how it will be paid (cash at closing, seller financing, or a combination), and any adjustments tied to working capital or inventory counts at closing. If the deal includes an earn-out, the LOI needs to define the specific performance metrics that trigger additional payments. Revenue and EBITDA are the most common benchmarks, and earn-out periods typically run up to three years. Vague earn-out language is one of the most reliable sources of post-closing litigation, so getting specific at the LOI stage saves money later.
The LOI should also address existing employee contracts and whether key staff will stay on after closing. Non-compete agreements that prevent the seller from launching or joining a competing business are standard. Non-compete terms are governed entirely by state law, and enforceability varies significantly depending on duration, geographic scope, and the restrictions imposed. A non-compete that’s reasonable in one state may be unenforceable in another.
Tax Allocation
In an asset purchase, both buyer and seller must agree on how the purchase price is allocated among the different classes of assets (tangible property, intellectual property, goodwill, and so on). Under federal tax law, that written allocation is binding on both parties for tax reporting. The IRS requires both sides to file Form 8594, which reports the allocation across seven asset classes. The buyer wants more value assigned to assets that depreciate quickly; the seller wants more allocated to capital gains categories taxed at lower rates. Those interests conflict directly, and negotiating the split early avoids a stalemate during final contract drafting.
Real Estate Letter of Intent
A real estate LOI anchors the deal around the property itself and the timeline from handshake to closing. The document should identify the property by its physical address and, for commercial transactions, by its tax parcel number or legal description. Commercial LOIs tend to be more detailed than residential ones because the stakes and complexity are higher.
Inspection and Due Diligence
The LOI should define the length of the due diligence period, during which the buyer can inspect the property, review environmental assessments, examine title records, and verify zoning compliance. For commercial properties, this window commonly runs 30 to 60 days. The LOI should also state whether the buyer can walk away without penalty if the inspection turns up significant problems. Without that exit ramp spelled out, a buyer who discovers contaminated soil or structural damage may still be on the hook.
Earnest Money
Earnest money shows the seller that the buyer is serious. In residential transactions, deposits typically range from 1% to 5% of the purchase price and are held in an escrow account by a title company or attorney until closing or termination. Commercial deals often push higher, sometimes reaching 10% depending on the property and the seller’s leverage. The LOI must state clearly whether the deposit is refundable or non-refundable, and if refundability expires after certain milestones (like the end of the inspection period), those dates need to be explicit.
Contingencies and Exclusivity
Financing and zoning contingencies protect the buyer from being locked into a purchase before securing a loan or confirming that the intended use of the property is permitted. These are standard in both residential and commercial LOIs. On the seller’s side, an exclusivity clause prevents them from shopping the property to other buyers during the negotiation period, typically for 30 to 90 days in commercial real estate. Some sellers negotiate exceptions that allow them to respond to unsolicited offers, particularly in competitive markets.
Joint Venture Letter of Intent
When two companies agree to pool resources for a specific project rather than one acquiring the other, the LOI looks quite different. A joint venture LOI focuses on the structure of the new entity, each party’s contribution, and the governance rules that will control the partnership.
The LOI should specify whether the venture will operate as an LLC, a partnership, or another structure. It needs to state each party’s initial capital contribution (cash, assets, intellectual property, or personnel), the ownership split, and how profits and losses will be divided. Governance terms matter here more than in most LOIs: who controls day-to-day operations, what decisions require unanimous consent, and how deadlocks are resolved.
Joint venture LOIs should also address what happens when one party wants out. Buyout formulas, rights of first refusal, and termination fees protect both sides from being trapped in a venture that stops working. These exit mechanisms are harder to negotiate after the venture is operating, so outlining them at the LOI stage is worth the effort.
Employment Letter of Intent
An employment LOI bridges the gap between a verbal job offer and a formal employment contract. It typically covers the job title, start date, base salary, bonus structure, benefits eligibility, and any relocation assistance. For executive positions, the LOI may also address equity compensation, severance terms, and reporting structure.
Over a dozen states and the District of Columbia now require employers to disclose salary ranges in job postings or during the hiring process. No federal law mandates salary disclosure in an LOI, but operating in a state with pay transparency requirements means the compensation section needs to align with what was already disclosed. Leaving the salary vague creates problems in those jurisdictions even if it wouldn’t elsewhere.
Employment LOIs are typically non-binding and explicitly state that the formal offer is contingent on background checks, reference verification, and any other conditions the employer requires. Including a response deadline, often one to two weeks, keeps the hiring process moving and prevents the offer from sitting open indefinitely.
Graduate School Letter of Intent
A graduate school letter of intent has almost nothing in common with its business counterpart except the name. There’s no negotiation, no purchase price, and nothing is binding. The document is a formal letter explaining why you want to attend a specific program and what you’d contribute to it. Many schools use “letter of intent” and “statement of purpose” interchangeably, though a letter of intent is typically formatted as an actual letter addressed to the admissions committee.
The content should connect past experience (research, publications, internships, relevant certifications) to the specific program. Generic letters that could be sent to any school are obvious and ineffective. Name specific faculty whose research interests align with yours, reference particular labs or centers, and explain concretely how the program advances your professional trajectory.
Signing, Delivering, and Keeping the Letter
Electronic signatures carry the same legal weight as ink signatures for LOIs. Under the federal Electronic Signatures in Global and National Commerce Act, a signature or contract cannot be denied legal effect solely because it’s in electronic form. Platforms that provide audit trails documenting who signed and when are standard practice. If a party prefers a physical signature, using a notary adds a layer of identity verification, though notarization is rarely required for an LOI.
Delivery method matters because the LOI typically includes an expiration date, often as short as 72 to 96 hours for competitive transactions. Certified mail or a secure email portal with read receipts creates a documented record that the letter was received before the deadline. Once both parties have signed, each side should keep digital and physical copies.
Retention is worth thinking about before you file the document away. Statutes of limitation for breach of contract claims run three to six years in most states, and the Uniform Commercial Code sets a four-year window for contracts involving the sale of goods. Hold onto the fully executed LOI and all related correspondence for at least that long if a dispute surfaces after the deal closes or falls apart.
