Legal analysis is the process of taking a specific set of facts, identifying the legal question those facts raise, finding the rule that governs the question, and applying the rule to the facts to reach a reasoned answer. It is the skill behind every legal memo, court brief, client letter, and judicial opinion. Most legal analysis is organized through a framework called IRAC, or a close cousin called CREAC, both of which force you to separate the law from the facts and then show your reasoning for connecting the two.
The IRAC Framework
IRAC stands for Issue, Rule, Application, and Conclusion. It is a repeatable structure: no matter how complicated the problem, you break it into these four steps for each question you need to answer. The method works because it keeps what you know (the law) distinct from what happened (the facts), and makes your reasoning visible on the page.
Issue
The issue is the specific legal question the facts raise. Getting it right matters more than any other step, because a vague issue sends everything after it off course. Ask what is actually in dispute. A good issue statement combines the legal concept with the key facts. “Is there a valid contract?” is too broad. “Did the parties form a binding contract when the buyer emailed acceptance after the seller’s written offer expired?” gives you something you can actually analyze.
Rule
Once you know the question, state the rule that answers it. A rule can be a statute, a regulation, a constitutional provision, a principle established by case law, or some combination. Lay out enough of the law to give the reader the framework they need to follow your reasoning. If the issue is whether a contract formed, the rule section explains the elements of a valid contract: offer, acceptance, consideration, and mutual assent.
Application
Application is where the real analytical work happens. You take each element of the rule and match it against the specific facts. The word “because” earns its keep here: “The offer was valid because the seller specified a price, a quantity, and a delivery date.” A weak application sets the rule and the facts next to each other and hopes the reader connects them. A strong application explains why the facts satisfy or fail to satisfy each element, drawing on analogies to prior cases where that helps.
Thorough application also means dealing with the other side. If there is a reasonable argument that an element wasn’t met, name it and explain why your reading is stronger. Skipping obvious counterarguments leaves a gap that a judge or supervising attorney will fill on their own, rarely in your favor.
Conclusion
The conclusion answers the issue you started with. Keep it direct: “A court would likely find that a valid contract existed because all four elements are satisfied.” If the analysis points different directions depending on how a court weighs certain facts, say so. Not every conclusion has to be absolute. What matters is that it follows from the application and doesn’t introduce new reasoning or new facts.
A Short Worked Example
Suppose a client slipped on an icy sidewalk outside a store and broke her wrist. She wants to know whether the store is liable. In miniature:
- Issue. Is the store liable for negligence when a customer slipped on ice that had accumulated on the sidewalk outside the entrance?
- Rule. A property owner is negligent when they owe a duty of care to the injured person, breach that duty by failing to act as a reasonable owner would, and that breach causes the injury.
- Application. The store owed a duty to keep its entrance reasonably safe for customers. The ice had been accumulating for several hours and no salt or warning signs were placed, which a reasonable store owner would have done. The customer’s fall and broken wrist followed directly from the unaddressed ice.
- Conclusion. A court would likely find the store negligent because it failed to address a known hazard within a reasonable time, and that failure caused the customer’s injury.
In practice each of those bullets might expand into several paragraphs with case citations and deeper factual discussion. The skeleton is the same.
CREAC and When to Use It
IRAC is not the only structure. Many legal writing programs teach CREAC: Conclusion, Rule, Explanation, Application, Conclusion. The underlying logic is identical, but two things change.
First, CREAC leads with the conclusion rather than the issue. You tell the reader your answer up front and then prove it. That makes CREAC a natural fit for persuasive writing like court briefs, where you want the judge to know your position immediately. IRAC fits objective writing like an internal memo, where the point is to explore a question rather than argue a side.
Second, CREAC adds an explicit Explanation step between the rule and the application. This is where you show how courts have interpreted the rule in prior cases before you apply it to your own facts. IRAC doesn’t forbid that kind of case illustration; CREAC makes it a required step, which often produces richer analysis. The closing conclusion in CREAC restates and reinforces the opening one.
Objective vs. Persuasive Analysis
The purpose of the analysis shapes how you write it. In objective analysis, like a memo to a supervising attorney, you lay out the law neutrally, apply it to the facts, and predict the most likely outcome without advocating for either side. If the law cuts against your client, you say so. The attorney reading the memo needs an honest picture to make strategy decisions.
Persuasive analysis works differently. In a court brief or oral argument, you take a position and marshal the strongest authority and reasoning for it. You still address counterarguments, but you frame them to minimize their weight. The facts are the same; the lens changes. Writing a persuasive memo when your supervisor needs an honest assessment wastes everyone’s time, and writing a neutral brief when you need to win a motion can lose the case.
Common Mistakes
Certain errors show up repeatedly, in student work and in practicing attorneys’ drafts alike.
- Vague issue statements. “Is there liability?” doesn’t guide anything. The issue needs the specific legal theory and the key facts.
- Rule dumps. Copying blocks of statutory text or long case quotes without synthesizing them. The reader needs you to distill what the law requires, not reproduce it.
- Thin application. Restating the rule and the facts without explaining the connection. Writing “the defendant had a duty and breached it” without showing how the conduct constituted a breach is the single most common analytical failure.
- Ignoring counterarguments. If the other side has a reasonable reading, skipping it doesn’t make it go away. It makes the analysis look incomplete.
- Confusing holding with dicta. A court’s holding is the legal principle that decided the case. Dicta are comments the court made in passing that weren’t necessary to the outcome. Treating dicta as binding overstates your position.
- Wrong jurisdiction. Citing a statute from one state in a matter governed by another state’s law, or relying on federal law when the question is purely a state issue. This happens more often than seasoned lawyers like to admit.
A Word on AI-Generated Analysis
Generative AI tools can draft research memos, summarize cases, and suggest arguments in seconds. They can also fabricate citations that look convincing and are completely fake. In a widely reported matter, a federal court in the Southern District of New York imposed a $5,000 fine and additional sanctions on attorneys who submitted an AI-generated brief containing six entirely fictitious court opinions with fabricated quotes.1Justia Law. Mata v. Avianca, Inc., No. 1:2022cv01461 – Document 54 The cases did not exist.
Since then, multiple federal judges have issued standing orders requiring attorneys to certify that AI-generated content in filings has been verified by a human, or to disclose AI use outright. In July 2024, the American Bar Association issued Formal Opinion 512 on lawyers’ ethical duties when using generative AI, grounding those duties in existing rules on competence, confidentiality, candor toward courts, and supervision.2American Bar Association. Rule 1.1: Competence
Treat AI output like a first draft from someone without a law license. Check every citation against a verified legal database. Trace every legal conclusion back to an actual statute or case. Confirm every jurisdiction reference. AI can speed up the early stages of research. It cannot replace the analytical judgment that turns raw legal materials into reliable analysis.3American Bar Association. A Practical Checklist for Using AI Responsibly in Your Law Firm
