Can you e-sign a lien waiver?
Yes. A lien waiver signed electronically is as valid as one signed in ink, under the federal ESIGN Act and the Uniform Electronic Transactions Act that nearly every state has adopted, and the state statutes that prescribe waiver forms ask for the claimant's signature, not a pen. The exceptions are forms that add a notary or a witness, such as Mississippi's and Wyoming's waivers or Georgia's witness line. There the claimant can still sign electronically, but the notary or witness step has to happen too.

The short answer
- An e-signature satisfies a signature requirement. That's the core rule of ESIGN and UETA, and lien waivers aren't on either law's list of exclusions.
- The state form still rules. If your state prescribes the wording, e-sign that wording. An electronic signature on the wrong form is still the wrong form.
- Notaries and witnesses don't disappear. Where a form includes a notary's jurat or acknowledgment, or a witness line, someone still has to perform that step, electronically where the law allows it.
- Payment rules don't change. Signing online doesn't make an unconditional waiver any safer to sign before the money clears.
What federal and state e-signature law say
The ESIGN Act says a signature or contract relating to a transaction in or affecting interstate commerce can't be denied legal effect solely because it's electronic (15 U.S.C. § 7001(a)). Its exceptions in § 7003 cover things like wills, family law matters, court documents and certain consumer notices; construction lien waivers aren't among them. State law says the same in plainer words:
If a law requires a signature, an electronic signature satisfies the law.
An electronic signature is any electronic sound, symbol or process attached to a record and adopted with the intent to sign it (UETA § 2(8)), so a drawn signature, a typed name or a click can all qualify. What makes it hold up is proof: UETA § 9 says a signature is attributable to a person if it was that person's act, which can be shown in any manner, including the security procedure used. That's why an audit trail of who opened, agreed and signed, and when, matters more than how the signature looks.
What the state waiver statutes ask for
These are the states we've checked against the statute text for our state-by-state guides. Most require only the claimant's signature.
| State | Who signs | Notary or witness |
|---|---|---|
| Arizona | Claimant or authorized agent | None |
| California | Claimant | None |
| Florida | Lienor, by an authorized person | None on waivers; the contractor's final payment affidavit is sworn before a notary |
| Georgia | Claimant, under hand and seal | Witness line on the waivers; the affidavit of nonpayment is notarized |
| Massachusetts | Contractor who recorded a notice of contract, under the penalties of perjury | None |
| Michigan | Lien claimant | None on waivers; sworn statements are notarized |
| Mississippi | Claimant | Notary jurat on both waiver forms |
| Missouri | Claimant, with printed name, title, address, phone and date | None on the residential final waiver |
| Nevada | Claimant or authorized agent | None |
| Texas | Claimant or authorized agent | None for original contracts from January 1, 2022; earlier contracts required notarization |
| Utah | Claimant or authorized agent | None |
| Wyoming | Claimant, or a person signing for it | Notary acknowledgment on the form |
In states without a statutory form, the waiver's own wording and the contract decide what's needed. Many contracts, lenders and title companies ask for notarized waivers even where the law doesn't, so check what the person collecting it requires.
When a notary or witness is involved
Both ESIGN and UETA allow electronic notarization. If a law requires a signature or record to be notarized, acknowledged, verified or made under oath, the requirement is met when the notary's electronic signature and all the other information the law requires are attached to or logically associated with the record (15 U.S.C. § 7001(g); UETA § 11). Many states also let notaries perform remote online notarization over audio-video, under their own notary laws. See remote online notarization.
SignMaster doesn't notarize documents. For a notarized form, the signer can choose Print and sign instead on the signing page, sign in front of a notary, and upload the notarized pages, which are added to the signed PDF; the certificate records that it was signed on paper. A witness, like Georgia's, can simply be a second signer on the same envelope. See how to add a witness.
What makes an e-signed waiver hold up
- The right form. Use the statutory wording where your state has it, unedited, with any required notice at the required size.
- The right signer. The claimant or someone authorized to sign for it. A GC signing on a sub's behalf defeats the purpose.
- Evidence of who signed. An email link sent to the signer, an access code for sensitive jobs, and a certificate of completion showing name, email, IP address and time.
- A record nobody can quietly change. SignMaster's certificate lists a SHA-256 fingerprint of each original file, so an altered copy won't match.
- The right timing. Conditional with the pay request, unconditional only once payment clears.
How GCs collect waivers from subs electronically
- 1
Set up one template per form
Upload each statutory form you use, per state, with New template. Name the role Claimant and add fields for the amount, through date and job details.
- 2
Send the conditional waivers with the draw
On paid plans, bulk send sends one form to every sub from a CSV, each with its own amount. Each sub signs from an email link on a phone or computer, with no account.
- 3
Pay against signatures
The bulk send's Results CSV shows every envelope's status, so you can hold a check for anyone who hasn't signed. Reminders and sign-by dates do the chasing.
- 4
Swap to unconditional once paid
When checks clear, send the unconditional form for the same amounts. Keep both waivers with the pay application in your project file.
- 5
Feed your other systems
On Crew and Company, a webhook on envelope.completed delivers every field value, such as the amount and through date, with a link to the signed PDF, ready for your accounting software.

Questions? Answers.
Is a lien waiver signed online legally binding?
Yes. ESIGN and UETA give an electronic signature the same effect as ink, and lien waivers aren't excluded. It still has to be the right form, signed by the right person.
Does a typed name count as a signature on a lien waiver?
It can. Under UETA an electronic signature is any symbol or process adopted with the intent to sign, so a typed name works if you can show the claimant adopted it to sign that waiver.
Do lien waivers have to be notarized?
Usually not. Most statutory forms need only the claimant's signature. Mississippi's and Wyoming's forms include a notary block, and Texas dropped notarization for original contracts from January 1, 2022.
Can a subcontractor sign a lien waiver on a phone?
Yes. With SignMaster the sub opens the email link on any phone, reviews the waiver and signs with no account or app. Where the form needs a notary, they can print, sign before one and upload it.
