Do I Need an M&A Lawyer Before I Sign a Letter of Intent (LOI)?

When a buyer and seller agree on key deal terms, it can be tempting to sign a Letter of Intent (LOI) quickly and “get the deal moving.” But before you put pen to paper, it’s worth asking a critical question: should you involve a mergers and acquisitions (M&A) lawyer before signing an LOI? The short answer is yes, and you will want to know why.

At Doggett Law Firm, we’ve seen too many business owners lose leverage or inadvertently limit their options by signing an LOI without proper legal review. While an LOI may appear to be a simple outline, it often sets the tone and legal foundation for the entire transaction. Based in San Antonio, our firm represents clients across Texas and nationally at rates lower than junior associates at large Houston or Dallas firms. We provide cost-effective, high-caliber representation backed by decades of M&A experience and an AV Rating from Martindale-Hubbell.

What a Letter of Intent Really Means

A Letter of Intent, or LOI, outlines the basic terms of a proposed business sale or acquisition before a definitive purchase agreement is drafted. It typically includes details such as:

• The purchase price or valuation range;
• The structure of the deal (asset vs. stock purchase);
• Payment terms and any earn-outs;
• Confidentiality and exclusivity (“no-shop”) clauses; and
• A general timeline for due diligence and closing.

Many business owners assume that because an LOI is “non-binding,” it’s harmless to sign. But in practice, certain provisions are legally binding, and the rest can significantly shape how the final agreement unfolds.

For example, confidentiality and exclusivity provisions almost always carry legal weight. Signing too quickly can prevent you from negotiating with other buyers or leveraging competing offers to increase value. Even “non-binding” deal terms can later become reference points that limit your ability to negotiate changes in the definitive agreement.

Why It’s Risky to Sign Without Legal Review

Once an LOI is signed, your bargaining position can drop dramatically. Buyers may treat the signed LOI as an informal commitment, and you may feel pressure to accept terms “because it’s already in writing.” Without a lawyer’s input, you could unintentionally agree to deal structures or terms that are unfavorable.

Here are some of the most significant risks business owners face when signing an LOI without legal guidance:

Unintended Binding Obligations

Even if labeled “non-binding,” an LOI can include clauses that create enforceable duties, such as confidentiality, exclusivity, or good-faith negotiation. Violating these provisions can expose you to serious legal and financial consequences.

Loss of Leverage

Suppose the LOI locks you into a low valuation, a limited buyer pool, or a one-sided exclusivity period. In that case, you may have no way to bring in competing offers or to renegotiate key terms later.

Tax or Structural Mistakes

The way a deal is structured —whether it’s a stock sale, an asset sale, or a merger—can have significant tax and liability implications. Your M&A lawyer from our firm can coordinate with tax advisors early to identify and fix potential problems before they become expensive.

Missing Protective Clauses

A well-drafted LOI can protect you by defining how due diligence will proceed, limiting the disclosure of proprietary information, and ensuring that key contingencies (such as financing or regulatory approval) are clearly stated. Skipping legal review means losing those safeguards.

How an M&A Lawyer Adds Value Early in the Process

Engaging an M&A attorney before signing an LOI isn’t just about avoiding mistakes; it’s about positioning yourself for a better outcome.

• Strategic Deal Structuring: Your attorney can help evaluate whether an asset sale or stock sale makes more sense for your goals, tax situation, and liability exposure.
• Valuation and Term Guidance: Lawyers familiar with M&A transactions know what’s market-standard in your industry and can identify hidden red flags, such as vague earn-out provisions or unrealistic closing timelines.
• Protecting Your Confidentiality: If you’re providing sensitive company data to a potential buyer, an attorney can ensure your LOI or a standalone NDA prevents misuse of that information, particularly if the buyer is a competitor.
• Negotiating Exclusivity: Buyers often push for a “no-shop” clause, which prevents you from considering other offers. A lawyer can limit the duration, scope, and exceptions to maintain your flexibility.
• Negotiate Key Protections: Sellers can negotiate stronger liability protections, like high deductibles and low liability caps, BEFORE signing the LOI.
• Preventing Future Disputes: By clarifying terms now, your attorney reduces the risk of misunderstandings later that could delay or derail the closing.
