Frequently Asked Questions

Are e-signatures legal for construction contracts?

Yes. E-signatures are legally binding under ESIGN Act and UETA for most construction documents. Some states have specific requirements for lien waivers—check local laws.

What about notarized documents?

Traditional notarization requires wet signatures. Remote Online Notarization (RON) allows digital notarization in many states. Check your state's rules.

How do I get subs to sign digitally?

Most subs prefer digital—it's faster. Include e-signature acceptance in your subcontractor qualification process. Use mobile-friendly tools.

What if someone doesn't have email?

Some tools allow in-person signing on your device. Alternatively, print, sign, and scan for those rare cases.

How secure are e-signatures?

Reputable tools use encryption and secure authentication. They're often more secure than paper documents that can be lost or forged.
