What this template was checked against
Before it is published, the template passes an automated check of these requirements:
- Amendment in a writing signed by both parties — UCC 2-209(2) and (3)
- Documents excluded from electronic signatures — 15 U.S.C. 7003(a) and (b)

This is a template, not legal advice.
The automated check covers only the laws listed here. The template does not replace a lawyer, and it cannot account for every situation, every state's rules or changes in the law after the date of the check. You use this document at your own risk: before signing, make sure it fits your situation.
