| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | The tool lists the petition date, the perfection date, and whether a financing statement was filed before or within 20 days after the debtor received delivery. It does not say the interest is property of the estate. |
| What the lawyer must review | 11 U.S.C. § 544(a) and UCC Section 9-317. As of commencement, and without regard to any knowledge of the trustee or of any creditor, section 544(a) gives the trustee the rights of a creditor that obtains a judicial lien, the rights of a creditor that obtains an execution returned unsatisfied, and the rights of a bona fide purchaser of real property other than fixtures. The trustee may avoid a transfer that is voidable by such a creditor. Section 9-317(a)(2), except as subsection (e) provides, subordinates a security interest to a person who becomes a lien creditor before the earlier of the time the interest is perfected or the time one of the conditions in Section 9-203(b)(3) is met and a financing statement covering the collateral is filed. Subsection (e), except as Sections 9-320 and 9-321 provide, gives a purchase-money security interest priority over the rights of a buyer, lessee, or lien creditor which arise between attachment and filing, if the financing statement is filed before or within 20 days after the debtor receives delivery. The lawyer decides whether the trustee may avoid the transfer. |

## Checking plan

- What the AI does: The tool lists the petition date, the perfection date, and whether a financing statement was filed before or within 20 days after the debtor received delivery. It does not say the interest is property of the estate.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- Article 9 in the sources is the uniform text. The lawyer reads the enacting state's current text before reliance. Section 9-203(b)(3) was not opened.
- Section 544(a) gives avoiding powers. The tool does not treat an unperfected interest as property of the estate by that fact alone.
- Section 544(b) follows an actual unsecured creditor and is a separate power. The tool does not apply it on these facts.
