## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Commercial & Corporate Advisory (contracts, company law, governance)](https://ailawframework.com/practice/commercial-and-corporate-advisory.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | Draft the letter from the facts and the questions the lawyer has marked, with a square-bracket gap for any fact or authority the file does not state. |
| What the lawyer must review | Read every sentence against the file before the letter is sent. Formal Opinion 512: uncritical reliance on generated text can fail Model Rule 1.1, and you remain responsible for the advice. Comment 8 to Rule 1.1 requires you to understand the technology used. Do not leave a citation in the letter until you have opened it. Model Rule 1.6: do not put the file into a public tool. |

## Checking plan

- What the AI does: Draft the letter from the facts and the questions the lawyer has marked, with a square-bracket gap for any fact or authority the file does not state.

## Notes

- A letter of advice states the lawyer's conclusion. The lawyer checks every sentence before it goes out.
- A citation the draft invents is deleted, not repaired from memory.
