Put the purpose at the top
Write a private working note with one sentence explaining what you want to understand. Avoid presenting a conclusion as an instruction unless you have already taken advice on it. “I want to understand this letter” gives a different starting point from “please file this application”. Keep your note off public search forms.
Use headings, not a life history
Try four small headings: the situation, the latest development, documents available and questions. Put dates beside events where you know them. An uncertain date should be marked uncertain. The lawyer may need a much fuller history later; the short brief simply helps you use the opening minutes well.
Leave a visible space for unknowns
Missing information can be important. List the records you cannot locate and questions you cannot answer without advice. Do not fill gaps with guesses just to make the page look complete. Ask the office which documents it wants before the meeting and use only its independently checked transfer method.
Keep the note as a prompt
Your brief is not an application, a witness statement or a legal opinion. Take it as a conversation aid and let the lawyer explain what else is needed. When the consultation ends, keep your own next-action note separate from the original account so that later advice is not confused with what you originally knew.
