## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Maritime, Shipping & Transport](https://ailawframework.com/practice/maritime-shipping-and-transport.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | From the ownership papers, record the owner type, the net tonnage if stated, whether a foreign documentation is mentioned, and whether the mortgage covers the whole vessel. Decide nothing. |
| What the lawyer must review | A certificate of documentation may be issued under 46 USC section 12103 only if the vessel is wholly owned by eligible owners, is at least 5 net tons, and is not documented under the laws of a foreign country. Eligible owners include a United States citizen, an association, trust, joint venture, or other entity whose members are citizens and which can hold title, a partnership whose general partners are citizens and whose controlling interest is owned by citizens, a corporation incorporated under United States or state law whose chief executive and board chair are citizens and whose noncitizen directors are no more than a minority of the number needed for a quorum, the United States Government, and the government of a State. The Secretary may issue a temporary certificate before measurement. A preferred mortgage under section 31322 includes the whole of the vessel, is filed in substantial compliance with section 31321, and covers a documented vessel or a vessel for which a documentation application is filed in substantial compliance with chapter 121. Section 31321 was not opened. Subsection (a)(4) limits mortgagees of certain fishery-endorsement vessels. Open it before you apply it. |

## Checking plan

- What the AI does: From the ownership papers, record the owner type, the net tonnage if stated, whether a foreign documentation is mentioned, and whether the mortgage covers the whole vessel. Decide nothing.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- There is no Australian-style shipping register in these sections. Documentation and the preferred mortgage are the opened path.
- Coastwise endorsement is a further question under chapter 121 and was not decided by section 12103 alone.
