## 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 | Apply the removal list the lawyer supplies, replacing each listed name, address, price and account number with a token, and flag any leftover item on that list. |
| What the lawyer must review | Model Rule 1.6: do not put client information into a tool that is not configured to keep it confidential. You read the output before it is sent, because a contract can identify the client by a deal term that is not on a standing list. Formal Opinion 512 does not treat a confidentiality setting as optional. This check is done on the contract in hand. It is not finished when the list was first written. |

## Checking plan

- What the AI does: Apply the removal list the lawyer supplies, replacing each listed name, address, price and account number with a token, and flag any leftover item on that list.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- A standing removal list is not enough on its own. The lawyer reads this contract before it goes into a tool.
- A token list kept in the file is what lets the lawyer put the names back. Do not send the token list with the contract.
