PLEASE NOTE

- Local ordinances can add rules (for example interest or receipts). The guide page lists the main ones to check.

- Digital download. No physical item will be shipped.

- Automatic totals work in Adobe Acrobat Reader (free) and most desktop PDF apps. Some apps (for example Apple Preview and some phone apps) do not run form calculations; type the totals yourself there or use the Word file.

- This is a template and general information, not legal advice. Laws change and local rules can add requirements. Check the current law and your lease, or talk to a local attorney.
