| 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 | From the certificate and the change filing, record the registered office address, including street, number, city, county and postal code, the registered agent at that address, the date the board resolution was adopted, and any later effective time stated in the filed certificate. Do not file the certificate. |
| What the lawyer must review | The lawyer decides whether § 131 is met: every corporation shall have and maintain a registered office in Delaware, which need not be a place of its business, at the address of its registered agent. A change of office or agent is a board resolution under § 133 and a certificate filed under § 103. An instrument filed under § 103 is effective on its filing date unless it states a later time, which cannot be later than the ninetieth day after filing. |

## Checking plan

- What the AI does: From the certificate and the change filing, record the registered office address, including street, number, city, county and postal code, the registered agent at that address, the date the board resolution was adopted, and any later effective time stated in the filed certificate. Do not file the certificate.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- A registered agent may change the office address under § 134 by its own certificate stating the day of the change. That is a different path from a § 133 board resolution.
- The registered office is in the state of incorporation. A corporation formed in another state follows that state's statute.
