So, is a term sheet legally binding? The honest answer is "partly", and problems start when a term sheet doesn't say clearly which parts are which. This article explains how binding and non-binding terms work, why the line matters, and how to draw it properly.

Why most of a term sheet is non-binding
A term sheet is signed early, usually before due diligence and before the full agreements are drafted. At that point neither side knows everything. If the price or the obligation to complete were binding, a party could be forced into a deal even after discovering a serious problem.
Keeping the commercial terms non-binding means:
- either side can walk away if due diligence uncovers issues;
- terms can be renegotiated as more information comes to light;
- nobody is locked in until the definitive agreements are signed.
Which terms are usually binding?
A small number of terms need to be binding from the moment the term sheet is signed, because they protect the parties during negotiations. They're only useful if they can be enforced.
| Term | What it does | Why it's binding |
|---|---|---|
| 🔒 Exclusivity | The other side agrees not to negotiate with anyone else for a set period | Protects the side spending time and money on due diligence |
| 🤐 Confidentiality | The deal and shared information are kept private | Protects sensitive information whether or not the deal goes ahead |
| 💸 Costs | Sets out who pays legal and other fees | Matters most if the deal doesn't proceed |
| ⏳ Expiry | How long the offer is open, and when the term sheet ends | Stops an old offer being accepted later |
| ⚖️ Governing law and disputes | Which law applies and how disputes are resolved | Any binding promise needs a law and a forum |
Which terms are usually not binding?
- Price, investment amount and valuation
- Payment terms and instalments
- Interest rates, security and repayment terms (for loans)
- Conditions such as due diligence and approvals
- Target dates for signing and completion
- Rights such as board seats, information rights or vesting
These are all intentions, recorded so everyone is aligned, but not yet legally enforceable.
How to make the line clear: the "legal effect" clause
The most important clause in any term sheet may be the one that says what is binding. A clear legal effect clause:
- Lists the binding paragraphs by name, for example "Exclusivity", "Confidentiality", "Costs", "Expiry", "Governing Law and Disputes" and "General".
- States that everything else is not binding and is not an offer or commitment to do the deal.
- Confirms that no party is obliged to proceed until the definitive agreements are signed.
- Says the final agreements prevail if they differ from the term sheet.
A simple version reads:
Save for this paragraph and the paragraphs headed "Confidentiality", "Costs", "Expiry", "Governing Law and Disputes" and "General", this Term Sheet is not legally binding and does not constitute an offer or a commitment by any Party to enter into the Proposed Transaction.
Keep the list accurate. If you remove exclusivity from a draft, remove it from the legal effect clause too. A mismatch creates exactly the kind of uncertainty the clause is meant to prevent.
Is a term sheet legally binding just because it says "non-binding"?
Not always. The label helps, but courts look at the whole document and the parties' conduct. Risks include:
- Silence. If the term sheet doesn't say what's binding, a court may decide the parties intended a binding contract, particularly if the terms are detailed and complete.
- Conduct. If the parties start performing the deal (for example, paying money or transferring assets) before signing the final agreements, that can suggest a binding arrangement.
- Good-faith duties. Legal systems treat negotiations differently. In many civil-law countries, such as Germany and France, walking away from negotiations in bad faith can create liability even without a binding contract. In the United States, some courts have treated detailed term sheets as binding the parties to negotiate in good faith. English law, by contrast, has traditionally been reluctant to enforce agreements to negotiate.
The practical lesson: say clearly what binds, act consistently with it, and check the rules of the governing law you choose.
Common requests that change legal effect
"Can we make the price binding?"
It's possible but unusual, and risky. It could oblige a party to proceed at that price even if due diligence reveals problems. Take legal advice before agreeing to it.
"Can we add a break fee or deposit?"
A break fee (a payment if one side walks away) is a binding financial obligation. Some legal systems won't enforce payments that operate as a penalty, so these need careful drafting and legal review.
"Can exclusivity bind both sides?"
Exclusivity usually binds only the party receiving the term sheet (for example, the company raising money). Mutual exclusivity is possible, but the wording needs adapting.
"Is a non-compete in a term sheet binding?"
Usually not. A non-compete in a term sheet is normally a commercial term that will be set out in the final agreement. Enforceability of non-competes also varies a lot between countries.
Frequently asked questions
Can I be sued for breaking a term sheet?
You can be sued for breaching its binding terms, such as confidentiality or exclusivity. Walking away from the non-binding terms is generally not a breach, although some legal systems impose good-faith duties during negotiations.
Is a signed term sheet a contract?
Its binding provisions form a contract. The rest of the term sheet is usually a non-binding record of intended terms.
Does a letter of intent work the same way?
Yes. Whether it's called a term sheet, letter of intent, heads of terms or MOU, what matters is what the document says about its legal effect, not its title.
How long does exclusivity usually last?
It depends on the deal. Periods of 30 to 90 days are common, with longer periods for more complex transactions. Longer exclusivity favours the side receiving it, so it's often negotiated.
