Start with the account relationship
Locate account-opening documents, advisory or brokerage agreements, fee schedules, authority forms, and any later amendments. Include the relationship summary if you received one. Note the legal account owner, account type, and the people authorized to give instructions.
Keep older versions when terms changed. A current agreement may not show the arrangement in place during the period in dispute. If a document is missing, put it on an outstanding-records list rather than filling the gap from memory. Ask the lawyer which requests should go to the firm.
Collect statements and transaction-level records
Gather statements covering a useful period before, during, and after the events that concern you. Keep complete PDFs, including footnotes and explanatory pages. Download available records through a trusted access route while you still have legitimate access.
Trade confirmations can show details that a monthly summary does not. Keep records of deposits, withdrawals, transfers, distributions, and charges too. Investor.gov encourages reviewing both account statements and confirmations and promptly raising discrepancies. A lawyer may need both to understand when an issue first appeared.

Preserve the explanations surrounding a decision
The reason given for a recommendation can be as important as the transaction itself. Save presentations, product documents, letters, emails, and complete relevant message threads. Include your questions and the replies, not just the one sentence that seems most useful.
- Keep original files separate from working copies.
- Use filenames with the date, account label, and document type.
- Record whether a date is exact or approximate.
- Preserve message context and available attachment information.
- Avoid editing a record to add an interpretation.
If you want to annotate something, do it on a clearly labeled copy. Ask counsel how to preserve material held in an app or portal without losing context.
Create an index rather than a document dump
A one-page index can identify the folder, date range, and question each group of records may help answer. Keep account numbers masked in an ordinary summary. Send sensitive documents only through the method the lawyer specifies; do not publish them in a public complaint or shared link.
A simple organization might use Agreements, Statements, Transactions, Communications, and Questions. Put missing periods in the index. It is more helpful to say that three statements are unavailable than to leave the reviewer wondering whether nothing happened during those months.
Prepare a short explanation of the gaps
Write a factual timeline and identify the few events that need closer review. Tell counsel whether you requested an explanation, who responded, and what you were told. Keep a separate list of potential witnesses and where each person fits into the history.
Do not access someone else’s account or restricted records to fill a gap. If documents are controlled by another party, the attorney can discuss lawful ways to request them. Preserve what you have and be clear about what remains unknown. The purpose of the file is to support an honest review, including facts that may weaken the claim.
