## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Mergers & Acquisitions / Private Equity](https://ailawframework.com/practice/mergers-and-acquisitions-private-equity.md) |
| Human involvement | Red: Lawyer writes; AI may check, clarify or collect data |
| How AI is used | Extract the buyer's foreign-person facts, the U.S. business, and whether the documents describe control or a real-estate deal, each with a source page. Do not say that a declaration or notice is required, and write no filing. |
| What the lawyer must review | Treasury describes CFIUS as the interagency committee that reviews certain foreign investments in U.S. businesses, and certain real-estate transactions by foreign persons, for national security. Its site is where a declaration or notice is started. You decide whether this deal is covered and whether to file. An Australian foreign-investment approval is not a CFIUS filing. Model Rule 1.1 and Formal Opinion 512 require you to verify the facts before you advise. Do not put the data room into a public tool. |

## Checking plan

- What the AI does: Extract the buyer's foreign-person facts, the U.S. business, and whether the documents describe control or a real-estate deal, each with a source page. Do not say that a declaration or notice is required, and write no filing.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- The Treasury overview does not itself state which transactions are mandatory. Read the current CFIUS rules before advising that a declaration is or is not required.
- Real-estate transactions are in the committee's remit on the Treasury page, separate from an investment in a U.S. business.
