## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Commercial Property & Leasing](https://ailawframework.com/practice/commercial-property-and-leasing.md) |
| Human involvement | Green: AI drafts, lawyer checks |
| How AI is used | From each lease, list commencement, expiry, option windows, notice addresses, and rent-adjustment dates in a table. Leave a cell blank when the lease is silent. Do not say an option was exercised. |
| What the lawyer must review | Option and rent-review mechanics are the lease. Where Texas Property Code Chapter 93 applies, a charge other than rent or physical damage must have its amount or method in the lease, an exhibit, or an amendment (§ 93.012). You confirm each date against the signed document before anyone relies on the diary. Formal Opinion 512: test the extraction on a sample before you trust the run. |

## Checking plan

- What the AI does: From each lease, list commencement, expiry, option windows, notice addresses, and rent-adjustment dates in a table. Leave a cell blank when the lease is silent. Do not say an option was exercised.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- A portfolio tool does not know which state's law governs each building. Keep the governing-law column for the lawyer.
- Do not apply an Australian retail-leases renewal notice to a US commercial lease.
