Electronic signatures are legally valid for most business contracts in the United States under the federal E-SIGN Act and state laws based on the Uniform Electronic Transactions Act. What matters is showing intent to sign, consent to do business electronically, and a reliable record of the signed version.
The legal basis
Federal law and the version of the Uniform Electronic Transactions Act adopted in Colorado both give electronic signatures the same effect as ink for most commercial agreements. A few document types, such as wills and certain notices, still follow separate rules.
| Usually fine to sign electronically | Check before signing electronically |
|---|---|
| Customer and vendor agreements | Wills and trusts |
| Offer letters and NDAs | Certain court filings |
| Purchase orders and statements of work | Documents requiring notarization |

“The software rarely decides a signature dispute. The record of who signed what, and when, usually does.”
