Preparing The Draft: Research And Organization

Efficient drafting begins with thorough research and careful organization. A well-researched memo rests on authoritative sources and transparent reasoning. Begin with a literature scan to identify controlling authorities and vibrant contrary authorities. Create an outline that maps each issue to the relevant rule and supporting authorities. This planning reduces rework and ensures a coherent flow from facts to conclusion.

Research Strategy

Adopt a targeted search approach: start with controlling statutes and leading cases, then expand to secondary sources for interpretation and synthesis. Verify jurisdictional relevance and stay aware of changes in law or recent decisions. Record pinpoint citations to facilitate easy reference in the final draft.

Organizational Outline

Structure the memo to mirror the logical progression of analysis. Use a consistent format for each issue: statement of issue, applicable law, analysis, and conclusion. A predictable structure improves readability for busy readers and helps ensure no critical authority is overlooked.

Use clear topic sentences, active voice where appropriate, and precise citations. Keep paragraphs concise and transitions smooth to maintain readability.

Structure Templates: Practical Formats

Two common formats accommodate most legal contexts. Choose the one that aligns with the audience and purpose of the memo.

Issue-Driven Format

Best for memos that address multiple questions. Each issue has its own section with a mini-IRAC (Issue, Rule, Application, Conclusion) or Rule-Application-Conclusion flow. This format highlights the analysis for each point separately.
