Is a Letter of Intent to Buy a Business Binding?

A letter of intent, often called an LOI or term sheet, is the document that kicks off most business sales. It lays out price, structure, and timeline before anyone drafts a purchase agreement. Buyers and sellers frequently treat it as a formality, something to sign quickly so the real work can start. That assumption causes problems. Parts of a typical LOI are binding the moment both sides sign, even though the document says the deal itself is not final.

Neither North Carolina nor Pennsylvania has a special statute that governs letters of intent in a business sale. Courts in both states fall back on ordinary contract principles: they look at what the document actually says, and they enforce the parts that read like a promise rather than a plan. That makes careful drafting, not boilerplate, the thing that protects you.

The default: most of an LOI is not binding

A well-drafted LOI usually opens with language stating that the document reflects the parties' current intent, that it is not an offer, and that no party is bound to complete the transaction unless and until a definitive purchase agreement is signed. Courts in NC and PA will generally honor that framing for the deal terms themselves: price, closing date, what assets or equity transfer, and so on. Either side can walk away from those terms without breaching anything, as long as the walkaway does not violate one of the binding provisions discussed below.

This non-binding status is the entire point of using an LOI instead of jumping straight to a purchase agreement. It lets both sides negotiate price and structure, line up financing, and start due diligence without either party being locked into a sale that might not survive a closer look at the books.

The exceptions: clauses that bind regardless

A handful of provisions in a standard LOI are written, deliberately, to be enforceable on signing. These are usually carved out in a separate section of the document, sometimes labeled "binding provisions" so there is no ambiguity. The most common ones:

• Exclusivity (no-shop). The seller agrees not to negotiate with other buyers for a set period, often 30 to 90 days, while the buyer spends money on diligence and legal fees. If the seller takes a better offer during that window, the buyer has a real breach-of-contract claim, even though the sale itself never closed.
• Confidentiality. Both sides typically agree to keep deal terms, financials, and business information private, and to use anything they learn only to evaluate the transaction. This obligation survives even if the deal falls apart entirely.
• Expense allocation. LOIs commonly state that each side bears its own legal and accounting costs regardless of outcome, or they allocate specific costs, such as a deposit on a quality-of-earnings report, to one party. That allocation is enforceable.
• Governing law and dispute resolution. If the parties are in different states, the LOI usually picks which state's law applies and how disputes get resolved. This clause binds even though the underlying deal does not.
• Standstill or break-up fees, when included. Some LOIs, particularly for larger deals, include a fee the buyer owes if it walks away after diligence is substantially complete without cause. These are less common in small business sales but do appear.

The practical effect: you can sign an LOI, walk away from the deal six weeks later because diligence turned up something you do not like, and still owe the other side performance on exclusivity, confidentiality, and expenses for the period the LOI was in effect.

How sellers accidentally sign a binding deal

The more serious risk is not that a clearly non-binding clause gets enforced. It is that the LOI's own non-binding language is weaker than the parties think, and a court or an aggressive opposing party treats the whole document as an enforceable agreement to sell. This happens a few ways:

The LOI uses mandatory language for deal terms instead of conditional language. A document that says the seller "shall sell" and the buyer "shall purchase" the business for a stated price reads very differently than one that says the parties "intend to negotiate" a purchase agreement reflecting those terms. Courts look at the actual words used, not the label on the document.

The LOI omits a clear statement that it is non-binding except for specifically listed sections. Silence is dangerous here. If the document does not say which parts are binding and which are not, a court has to guess at the parties' intent by looking at the whole document, the parties' conduct, and the surrounding negotiations.

The parties act like the deal is done. Emails that say "once we close" instead of "if we close," a seller who starts laying off staff or notifying customers, a buyer who starts operating the business before a purchase agreement is signed: all of this can be used as evidence that the LOI was understood as the final deal, regardless of what the document itself says.

There is also no price point or deal size where this stops mattering. A straightforward acquisition of a small local business carries the same risk as a larger transaction if the LOI is poorly drafted. If anything, smaller deals are more exposed, because the parties are less likely to have counsel review the LOI before signing, and more likely to negotiate by email in a way that blurs the line between the term sheet and the deal itself.

What this means before you sign

Read an LOI the way you would read any contract, not as a placeholder. Identify which sections are labeled binding and understand exactly what obligation each one creates, including how long it lasts. Confirm that the deal-terms sections use language that keeps them non-binding. And be careful with your own conduct and correspondence after signing: treating the LOI as a done deal can undo the protection the document was supposed to give you.
