Legal memos are time-intensive. A well-researched memo can take 4-8 hours. AI won’t replace the legal analysis, but it can cut the drafting time in half by handling the structure, initial research summary, and formatting.

The Legal Memo Prompt Framework

Issue Identification

“I need to analyze [legal issue] for a client in [jurisdiction]. The key facts are: [facts]. Identify the 3-4 main legal issues I should address in a memo. For each, note the relevant area of law and key questions to answer.”

Research Summary

“Summarize the current state of law regarding [specific issue] in [jurisdiction]. Include: the general rule, key exceptions, leading cases (with citations), and any recent developments. Note: I will verify all citations independently — focus on giving me a comprehensive overview of the legal landscape.”

Memo Draft

“Draft a legal memorandum analyzing [issue]. Facts: [facts]. Jurisdiction: [state/federal]. Structure: Question Presented, Brief Answer, Statement of Facts, Discussion (with IRAC for each issue), Conclusion. Tone: objective analysis, not advocacy. Flag areas where the law is unsettled or where additional research is needed.”

Client-Friendly Summary

“Take this legal analysis: [paste memo discussion section] and rewrite it as a 1-page client letter. Explain the legal issues in plain language, state our recommendation clearly, and outline next steps. The client is a [business owner/individual] who is not a lawyer.”

Critical Warning

AI-generated legal citations are frequently wrong — hallucinated case names, incorrect citations, and fabricated holdings. Always verify every citation against Westlaw, LexisNexis, or primary sources. Use AI for structure and analysis frameworks, not as a citation source.

Pro Tips for Better Legal Memo Prompts

Specify the standard of review. If you’re analyzing a motion to dismiss, tell AI it’s a 12(b)(6) standard. If it’s summary judgment, say so. The legal framework changes the entire analysis.

Feed it the actual cases. Instead of asking AI to find cases (where it hallucinates), paste the relevant cases you’ve already found and ask AI to analyze them:

“Here are the three leading cases on [issue] in [jurisdiction]: [paste key holdings]. Analyze how these cases apply to my client’s facts: [facts]. Identify which case is most favorable to our position and why. Note any distinguishing facts.”

Use AI for the counter-argument. The best memos anticipate the other side. After drafting your analysis:

“Now argue the opposite position. What’s the strongest counter-argument to the conclusion in this memo? What cases or facts would the opposing party rely on? How would we respond to each counter-argument?”

Iterate, don’t one-shot. A single prompt won’t produce a usable memo. Use AI in stages: issues first, then research framework, then draft, then refinement. Each stage builds on the last and gives you checkpoints to correct course.
