37. Transactional, Regulatory, and Advisory Practice

37.1 Match the source to the client's question

A client memorandum may ask what the law requires, what an agency currently says, what a contract permits, or what market participants commonly do. These are different propositions. Identify the source type supporting each claim and avoid merging law, guidance, private agreement, and observation into one unqualified statement.

37.2 Use an authority-and-assumption table

For each material conclusion, record the governing source, version, relevant facts, assumptions, and unresolved question. This lets another reviewer see where a conclusion depends on facts supplied by the client or a regulatory interpretation that has not been tested. An assumption should not become an asserted fact merely because it appears in a polished memorandum.

37.3 Maintain regulatory change records

Record the publication, effective, and compliance dates separately. Identify which business process or contract clause could be affected. Link the exact instrument and relevant section, not only an agency news release. A news release can alert the team to a change; the operative source must establish what changed.

37.4 Write for nonlawyer readers without losing support

Use plain explanations in the body and precise references in notes or an accompanying source list when appropriate. Define unusual source names and explain the practical significance of dates and versions. A client should be able to distinguish a firm conclusion from a question requiring further facts or jurisdictional advice.

Avoid filling the document with unexplained abbreviations merely because the audience includes lawyers. A source citation should reduce uncertainty, not introduce a decoding task that obscures the recommendation.

37.5 Reuse carefully

Before reusing a prior memorandum, compare the jurisdiction, operative facts, document type, governing version, and assumptions. A correct analysis from another matter can become wrong through changed facts or law. Preserve useful research notes, but reopen central sources and update the status record. A firm's precedent bank is a research starting point, not a permanent warranty.

Fictional exercise. A prior memo concluded that notice by email satisfied a particular agreement. A new transaction prohibits electronic notice for termination. Reusing the old conclusion would fail at the source and facts stages. Identify the new clause and its exceptions before adapting the citation or recommendation.
