Writing a Legal Memorandum

Updated 7 min read
Key takeaway

A legal memorandum answers a defined question for a specific reader.

  • State the short conclusion, explain the governing rule, apply supporting and opposing facts, and identify uncertainty or next steps.
  • Use headings that reflect the assignment, cite the supplied authority accurately and avoid writing a generic essay when a practical recommendation is needed.

Define the assignment and audience

Before writing, identify who will read the memorandum, what decision they need and what form the task requests. A supervising lawyer may want a candid risk analysis; a client may need a plain-language recommendation; a court filing follows a different structure. The prompt's instructions control the response.

Note any word limit, deadline, issues to address and supplied sources. If the assignment asks for a recommendation, do not stop after describing the law. If it asks for an objective analysis, discuss adverse authority and facts.

Use a clear structure

A practical memorandum often includes a question presented, short answer, relevant facts, discussion and conclusion or recommendation. Under time pressure, headings can be concise and adapted to the requested product. Put the answer near the beginning so that the reader can orient quickly.

The short answer should give the likely result and its key reason. The facts section should include material facts from the record without argument. The discussion should organize the rule and application by issue. The conclusion should state what the client or supervising lawyer should do next.

Explain rule and application

State the governing rule with its elements, exceptions and relevant limits. Cite the supplied statute or case so the reader can trace it. Then apply each element to the facts. A useful paragraph connects rule, evidence and consequence rather than repeating a rule or making an unsupported prediction.

Address favorable and unfavorable evidence. If a case supports the client's position, compare its decisive facts with the file. If another authority points the other way, distinguish it only if the facts or rule justify the distinction. Honest treatment of a weakness makes the recommendation more credible and useful.

Handle uncertainty precisely

Separate uncertainty about law from uncertainty about facts. A legal issue may be unresolved because sources conflict; a factual issue may depend on a missing receipt or witness. Explain what additional research or evidence would matter and how different answers could alter the result.

Avoid certainty unsupported by the record. Instead of saying ‘the client will prevail,’ state the strongest current conclusion, its basis and the principal risk. Do not hedge every sentence; identify the specific condition that makes the result uncertain.

Write for usability

Use direct sentences, descriptive headings and defined terms. Remove background that does not affect the issue. Use a table only when comparing several elements, options or dates will make the analysis easier to follow. Keep legal jargon when it is precise, but explain it for a nonlawyer audience.

A recommendation should translate analysis into action. State what to preserve, whom to contact, what deadline applies, what further fact to obtain and what choice the client must make. Keep the next step within the lawyer's authority and the client's objectives.

A timed drafting sequence

  1. Outline the answer and headings before drafting full paragraphs.
  2. Write the conclusion and key rule in plain language.
  3. Apply the strongest facts element by element.
  4. Address the most important counterargument and uncertainty.
  5. Finish with a recommendation or next step matching the assignment.
  6. Proofread for task completeness, source support, dates and clarity.

Short example

Question: Can the client terminate the supply contract today? A useful short answer might be: ‘Probably not yet. The agreement requires written notice and a 10-day cure period, and the file shows an email but does not establish receipt at the contract address. Confirm delivery and calculate the cure period before sending a termination notice.’ The discussion would then analyze the contract text, evidence of delivery and available remedies.

This answer is useful because it resolves the question, ties the recommendation to the governing condition and identifies the fact that remains to be confirmed. It avoids a broad essay on contract breach.

Use the memorandum structure the task needs

A legal memorandum is a work product, not a fixed form. Follow the assignment's requested format and reader. An internal analysis may use a question presented, short answer, facts, discussion and recommendation. A client memorandum may put options and next steps first. A task with a word limit or required headings takes priority over a generic template.

Start with the short answer: state the likely result and its main reason. Then provide only the facts needed to understand the analysis. Organize discussion by issue, claim or required decision. End with a recommendation, next step or unresolved question that the reader can act on.

Write rule paragraphs that lead to application

State the rule's elements, key exception and source. Then apply the record to each element. A rule paragraph should not become a copied outline that delays the issue. Use a citation or source name accurate enough for the reader to verify the proposition. Where authority is supplied, identify the case or statute in the manner the assignment expects.

For a notice-and-cure issue, state who must receive written notice, what the notice must say and how long the recipient has to cure. Then compare the contract address, email content, delivery evidence and dates. If the email was sent to the wrong person, explain whether actual receipt changes the analysis under the supplied authority.

Address adverse facts without losing the recommendation

A credible memo identifies the strongest argument against the client's position. Explain whether the adverse fact changes an element, raises credibility or creates uncertainty. Do not bury the weakness in a vague caveat or overstate a favorable case. If two outcomes are possible, state the condition that separates them.

If a client claims a supplier missed three deadlines but the project logs show one delay caused by the client's late approvals, separate the events. The contract may treat repeated supplier delay differently from a delay excused by the client. Explain the strongest argument for termination and the risk created by the approval record. The recommendation can still be direct while acknowledging the contrary evidence.

Legal uncertainty exists when authorities conflict or leave a question open. Factual uncertainty exists when the record does not establish what happened. Do not describe a missing delivery receipt as an unsettled rule. Identify the evidence needed and how each possible answer affects the legal conclusion.

A useful formulation is conditional and specific: “If the email reached the contract-designated address on May 3, the cure period may have expired before termination; if it reached only the account manager's personal inbox, the notice requirement may remain unsatisfied.” This tells the reader both the uncertainty and the next step.

Choose headings and detail for the reader

Headings should reflect the question, such as “Was notice effective?” or “Can the client terminate now?” Use short paragraphs that connect rule, fact and consequence. A supervisor may want detail about authority and litigation risk. A client needs practical options and plain-language consequences. Keep technical language when precision requires it, but explain terms that affect the reader's choice.

Do not include every background fact. Include facts that bear on an element, defense, remedy, credibility or recommendation. A concise timeline can help when dates control. A table can help compare several options, but a table should not replace explanation of why one option is preferable.

A complete timed drafting method

Read the task and identify every requested output. Build an issue outline with the controlling authority and decisive facts. Draft the conclusion first, then organize the analysis. Address the strongest counterargument, identify any missing evidence and state next steps. Reserve a final check for task compliance, citation accuracy, names, dates and whether the recommendation follows from the analysis.

A polished opening does not compensate for an unanswered question. If time is short, complete each requested section at a clear level before refining style. After practice, diagnose whether lost quality came from reading, research, issue selection, analysis or drafting. Change that step in the next exercise rather than rewriting every sentence.

Final check: answer every requested question

Before submitting, compare the draft against the assignment. Confirm that each requested issue has a conclusion, each important rule has source support, and each disputed fact is described accurately. Check that the recommendation follows from the analysis and that the reader knows the next step. A memorandum can be concise and still complete.

If the task asks whether to terminate and what notice to send, answer both. If the conclusion depends on receipt, state the consequence and identify the record needed. Do not leave an issue unresolved merely because another issue has a stronger answer.

Common questions

What is the most important part of a legal memorandum?

Answering the assigned question with supported legal analysis and a recommendation suited to the reader.

Should a memorandum discuss facts against the client?

Yes. Address material adverse facts and explain how they affect the likely result or next step.

Is IRAC required?

A rule-application structure is useful, but follow the task's requested product and audience rather than forcing a rigid template.
