Avoiding Ambiguity: Why Word Choice Matters in Legal Writing

Written by: Tyler Hurst, Lex Tecnica Law Clerk

Albert Einstein is credited with saying, “If you can't explain it simply, you don't understand it well enough.” That principle applies to legal writing as much as any other kind of writing. Clear legal writing is not simplistic. It is disciplined. It reflects a strong command of both the subject matter and the reader’s needs. 

Good legal writing is not just about sounding polished or professional. It is about clarity. Whether the document is a client email, a demand letter, a motion, a policy, a contract, or an internal memorandum, the writer’s job is the same: communicate complex ideas in a way that is accurate, understandable, and useful to the reader. 

That is where word choice matters. A vague phrase, an undefined term, or an overly complicated sentence can create confusion even when the writer believes their meaning is obvious. In legal writing, ambiguity is rarely harmless. It can lead to misunderstanding, weaken an argument, frustrate a client, or leave too much room for misinterpretation. 

At the end of the day, legal writing is not just for lawyers by lawyers; it is read by many different audiences. Sometimes the reader is a client with no legal training. Sometimes it is a judge, trying to understand the practical effect of a legal issue. In each of those situations, the writing needs to do more than sound competent. It needs to communicate clearly. Simply. 

Ambiguity Undermines More Than Style 

Many people treat unclear writing as a minor style issue. It is more than that. Ambiguous legal writing can create real problems long before anyone disputes the substance of the issue. 

A client who reads a legal memorandum shouldn’t guess at the recommendation. A judge reading a brief shouldn't have to work excessively to determine the point of the argument. When legal writing leaves the reader uncertain, the problem is not only readability. As a result of unclear writing, the problem becomes one of function. 

Poor word choice can also affect credibility. When legal writing is vague, repetitive, or unnecessarily complicated, the reader may question whether the writer fully understands the issue. That is especially true when the subject matter is already difficult.  

In that sense, clarity is not an issue separate from persuasion. It is persuasion itself.  

Where Ambiguity Usually Starts 

Ambiguity in legal writing often begins with habits that are easy to overlook. Mark Twain said “Habit is habit, and not to be flung out of the window by any man, but coaxed downstairs one step at a time.” Habits can be broken.  

One of the most common poor writing habits is permitting abstract or open-ended language when more precise wording is available. Terms like “reasonable,” “significant,” “substantial,” or “timely” may have a place in legal analysis, and they may sound punchy, but they should be used carefully and only when the context surrounding the term is clear. Without context, those words can leave the reader with more questions than answers. 

Another common issue is unnecessary complexity. Legal writers sometimes assume that longer sentences and more formal vocabulary make a document sound more authoritative, when, in reality, they just make it more complex. When a sentence is overloaded with clauses, qualifiers, and dense phrasing, the reader has to spend more time untangling the structure than they spend understanding the point, creating a legal writing “gordian knot.”  

Inconsistent terminology can also create confusion. If a document uses different terms to refer to the same idea, person, or legal standard, the reader may stop to wonder whether a distinction was intended. Remember, any pause that interrupts the flow of the analysis weakens the overall presentation. 

Precision Strengthens Analysis and Communication 

Good legal writing depends on precision because legal issues often turn on nuance. A small difference in wording can change how a rule is understood, how a fact is framed, or how a conclusion is received. 

This is especially important when legal writing is analytical or persuasive. In a memorandum, precise language helps separate the governing rule from the writer’s interpretation of it. In a motion, it helps present facts and arguments in a way that is both accurate and compelling. In client-facing writing, it helps translate legal complexity into practical guidance. 

Clear word choice also makes legal advice more useful. Clients are not usually looking for the most technical explanation. They want to know what the issue is, why it matters, what the risk looks like, and what they should do next. Quick, dirty, and to the point. Just practical information. Legal writing that answers those questions directly is far more valuable than writing that simply restates doctrine in a formal, and frankly foreign, language to the layperson. 

This is one reason plain language matters so much in legal practice. Plain language expresses analysis in a way that is easier to understand. 

Practical Ways to Write More Clearly 

Clear legal writing is usually the result of deliberate choices. One of the simplest ways to improve it is to choose concrete words. If the point can be made more directly, it usually should be. A sentence built around specific actors, actions, and consequences is often stronger than one filled with abstractions. 

It also helps to keep sentences simple. Not every sentence needs to be short, but every sentence should be easy to follow. When a sentence contains too many ideas at once, it often becomes less effective. Breaking a long sentence into two can improve clarity immediately. 

Writers should also pay attention to whether each paragraph has a clear purpose. A strong paragraph guides the reader. It begins with a point, supports that point, and then moves on. If the paragraph wanders, repeats itself, or buries the conclusion, the writing loses force. 

Reading for your audience is another important habit. A document written for a judge will sound different from one written for a client, but both should be clear. Before finalizing any piece of legal writing, it helps to ask a simple question: Will this make sense to the intended reader? Asking this question sentence by sentence, paragraph by paragraph, is usually unnecessary. However, asking with the entire document in mind, or perhaps a particular section of the document, is an effective method of gauging your clarity and tone. 

Finally, revision matters. Legal writing often improves most after the first draft is done. Nobody ever says exactly what they want to say, exactly how they want to say it, on the first pass. Write with the knowledge that revision is, and should be, the final step for any legal document. 

Conclusion 

Ambiguity in legal writing is not just a stylistic weakness. It can create confusion, weaken analysis, and make legal guidance harder to understand. Careful word choice helps prevent those problems by making writing clearer, more precise, and more effective for its intended audience. 

The strongest legal writing is not the most eloquent. It is the clearest and often the simplest. When legal ideas are explained with precision and simplicity, they are more likely to inform, persuade, and serve the people who need them.
